MKP1840268014 概要

The Vishay MKP1840268014 is a 6.8 nF (6800 pF) metallized polypropylene (PP) film capacitor rated for 100 V DC continuous operation (with a 63 V AC rating) in a radial-lead through-hole package with 5 mm lead pitch. It is part of Vishay's MKP1840 series, a long-standing family of metallized PP film capacitors optimized for DC link, snubber, and high-frequency filtering roles that demand tight capacitance tolerance and low dissipation.

A film capacitor (also called a plastic-film or polymer-film capacitor) is a passive component that stores electrical energy in a thin polymer film such as polypropylene (PP), polyester (PET), or polyethylene naphthalate (PEN). Metallized film capacitors use a vacuum-deposited metal layer as the electrode directly on the film surface, which gives them a graceful self-healing behavior under voltage stress and a smaller package than foil-electrode constructions. Within the broader capacitor taxonomy, MKP1840268014 sits under film capacitor -> plastic-film capacitor -> metallized polypropylene (MKP/PP) capacitor -> DC link/snubber/signal coupling capacitor -> passive component.

Key features include a ±5 % capacitance tolerance (EIA standard M-class), stable capacitance across temperature (PP dielectric has a temperature coefficient of roughly -250 ppm/K and very low dielectric absorption), a typical dissipation factor tan(δ) on the order of 0.001 at 1 kHz, and an insulated radial-leaded construction suitable for automated insertion or hand wiring. PP film inherently delivers high insulation resistance, low loss across capacitance, and excellent frequency response, making MKP1840268014 well-suited to applications where capacitance must not change with temperature, frequency, or applied voltage.

The MKP1840 series is widely specified as a drop-in PP film capacitor in switched-mode power supplies, electronic ballasts, and audio coupling/decoupling networks where the alternative polyester (PET, MKT) or epoxy-dipped ceramic would distort or drift. Polypropylene's very low dielectric absorption (~0.05 %) makes it preferable for sample-and-hold, AD/DC reference, and analog signal-path designs that must hold a charge accurately.

Typical applications include SMPS output filtering after the rectifier, high-frequency snubber networks across switching transistors and rectifiers, DC-blocking in audio signal paths, timing and oscillator circuits, and general-purpose coupling in analog front ends. The 5 mm pitch and 100 VDC rating make it convenient for 24 V and 48 V industrial rails where it functions as a Y-class-like bypass or X-class-like across-the-line filter capacitor (consult the datasheet for safety class certification).

When designing with this part, keep lead-forming stress to a minimum so the through-hole terminations do not crack the epoxy seal, and verify the operating AC ripple current and dV/dt against the manufacturer datasheet. For surface-mount designs the MKP1840 series is not the right choice - consider Vishay's MMKP or stacked SMD PP families instead.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond the manufacturer datasheet alone, giving buyers and engineers a single source of truth for the MKP1840268014.

主な用途

MKP1840268014 の用途: 6 件s: SMPS Output Filtering, Switching Transistor Snubber, Audio Signal Coupling, Timing and Oscillator Circuits, DC-Blocking and Line Filtering, Sample-and-Hold and ADC Reference.

⚡

SMPS Output Filtering

The Vishay MKP1840268014 fits SMPS secondary-side output filtering because its 100 VDC rating covers the rectified rail of 24-48 V industrial SMPS designs, and its 6.8 nF capacitance complements the main bulk electrolytic to filter switching ripple above 100 kHz. The polypropylene dielectric's low dissipation factor (~0.001 at 1 kHz) keeps self-heating minimal under continuous ripple current, while the 5 mm radial pitch is compatible with standard through-hole PCB layouts for analog and power boards.

⚡

Switching Transistor Snubber

Across switching transistors, IGBTs, and rectifiers the MKP1840268014 acts as a low-energy RC snubber. The PP dielectric tolerates the high dV/dt and repetitive voltage spikes that occur at turn-off of the switching device, and the 100 VDC rating covers secondary-side snubber positions in 24-48 V power converters. Compared with ceramic snubbers, the metallized PP construction self-heals after dielectric breakdown, improving field reliability in snubber service.

🎧

Audio Signal Coupling

In audio signal-path coupling, the MKP1840268014's polypropylene film provides very low dielectric absorption (~0.05 %) and a near-flat frequency response across the 20 Hz to 20 kHz audio band. This preserves transient fidelity and tonal balance compared with polyester (MKT) alternatives, which introduce measurable phase distortion at high audio frequencies. The 6.8 nF value forms an effective -3 dB point well below 20 Hz with typical 10 kohm to 100 kohm source and load impedances used in line-level audio stages.

🔧

Timing and Oscillator Circuits

In RC-based oscillator networks (e.g., 555 timer astable circuits, analog oscillator loops, or PLL filter positions), the MKP1840268014's stable ±5 % capacitance tolerance and PP dielectric's low temperature coefficient (~-250 ppm/K) keep the timing period predictable across operating temperature. The 100 VDC rating leaves generous headroom over typical 5-15 V timing-node voltages, and the through-hole radial package is convenient for breadboard and through-hole prototype assemblies.

🏭

DC-Blocking and Line Filtering

The MKP1840268014 functions as a DC-blocking capacitor in series with signal paths or as a Y/X-class-like line filter in low-voltage industrial installations. The 100 VDC rating and 63 VAC rating cover 24 VAC and 48 VDC industrial rails, while the polypropylene dielectric maintains low leakage current across the operating temperature range. Its 5 mm pitch fits standard through-hole PCB layouts used in industrial controllers and PLC analog modules.

🖥️

Sample-and-Hold and ADC Reference

In sample-and-hold and ADC reference filtering, the MKP1840268014's very low dielectric absorption (~0.05 %) makes it preferable to ceramic or polyester alternatives for hold-capacitor duties where droop and feedthrough errors must be minimized. The 6.8 nF value combined with the low-leakage PP dielectric provides a stable reference voltage during the ADC acquisition window, improving ADC measurement accuracy in precision instrumentation.

What is the pinout of MKP1840268014?
The Vishay MKP1840268014 is a two-terminal passive device in a radial through-hole package with two straight leads exiting the bottom of the epoxy-sealed body. As a non-polarized film capacitor, it has no pinout in the IC sense - both leads are electrically equivalent and connect across the load or filter node; the orientation on the PCB is irrelevant.
Is MKP1840268014 suitable for audio coupling applications?
Yes, the Vishay MKP1840268014 is well-suited for audio coupling and decoupling because its polypropylene dielectric has very low dielectric absorption (~0.05 %) and a near-flat frequency response across the audio band. Compared with polyester (MKT) alternatives, MKP1840268014 introduces less phase distortion at high frequencies and exhibits more stable capacitance versus temperature, which preserves tonal balance in audio signal paths.
Can MKP1840268014 be used as a snubber capacitor?
Yes, the Vishay MKP1840268014 is suitable for low-energy snubber applications across switching transistors and rectifiers operating below 100 V DC. Its polypropylene dielectric handles the fast voltage transitions typical of snubber circuits, and the 100 VDC rating covers most low-voltage secondary-side snubber positions. For high-energy snubber roles, verify the dV/dt and peak current ratings against the MKP1840 datasheet.
What are the key specifications of MKP1840268014 that engineers should know?
The Vishay MKP1840268014 is defined by 6.8 nF ±5 % capacitance, 100 V DC continuous rating, 63 V AC rating, polypropylene (PP) metallized film dielectric, 5 mm radial lead pitch, -55 °C to +100 °C operating range, and self-healing behavior. Engineers should also note the very low dielectric absorption (~0.05 %), stable capacitance versus temperature, and the unsuitability of this through-hole part for SMT PCB designs.

主な差別化要因

  • Same-package capacitance variants in MKP1840 family for design tuning （vs MKP1840310014 (10 nF))
  • Polypropylene dielectric with low dielectric absorption （vs MKT (polyester) capacitors)
  • Cross-brand second source availability （vs KEMET PHE426 and WIMA FKP2)

設計ノート

Do not assume any Vishay MKP1840 series part is interchangeable on capacitance: the part-number suffix '014' identifies the 100 V DC / 5 mm pitch variant, while the '268' mid-section encodes 6.8 nF. For example, MKP1840310014 is 10 nF in the same 100 V / 5 mm package, which will change RC time constants and filter cutoff frequencies. Always verify both voltage rating and capacitance value before substituting MKP1840 family parts on the same PCB footprint.

When mounting the MKP1840268014, avoid bending the leads too close to the body of the capacitor. The recommended minimum bend distance is 1.5x the lead diameter away from the epoxy seal, and the bend radius should be at least 1 mm to prevent cracking the seal. Use lead-formation tools rather than pliers to avoid mechanical stress on the capacitor body, which can compromise the metallized-film construction.

Estimated: at a typical 100 kHz SMPS secondary ripple of 50 mA RMS applied to the MKP1840268014, the AC voltage across the part is approximately V = I / (2πfC) = 0.05 / (2π × 100000 × 6.8e-9) ≈ 11.7 V. This is well below the 63 V AC rating, leaving generous margin. For higher-frequency or higher-ripple applications, recalculate the AC voltage using the actual operating frequency and RMS ripple current to ensure margin against the AC rating.
