CL31B104KEHNNNE Visão geral
A multilayer ceramic capacitor (MLCC) is a passive surface-mount component constructed from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic block with external terminations. MLCCs are the most widely used capacitor technology in modern electronics due to their small size, low cost, excellent high-frequency performance, and wide capacitance range. Within the capacitor taxonomy, MLCCs belong to the ceramic capacitor family, which itself sits under fixed capacitors -> passive components -> discrete electronic components. X7R is a Class II dielectric that offers moderate volumetric efficiency (roughly 10× the capacitance per volume versus C0G/NP0) while maintaining acceptable temperature stability (±15 % capacitance change across -55 °C to +125 °C), making it the workhorse dielectric for general-purpose decoupling, filtering, and bypass applications.
Key features of the CL31B104KEHNNNE include 250 V DC rated voltage (suitable for 120/220 V mains-derived auxiliary rails and industrial 24 V buses), ±10 % capacitance tolerance (K-code in Samsung's nomenclature), X7R temperature characteristic (X = -55 °C min, 7 = +125 °C max, R = ±15 % capacitance shift), and a 1206 case (3.2 mm × 1.6 mm EIA standard). The Ni-barrier + Sn matte-trim terminations support lead-free reflow soldering up to +260 °C peak.
From an engineering perspective, X7R's capacitance decreases with applied DC bias (typically 15-30 % at rated voltage for 100 nF values), and designers should verify effective capacitance at the operating point. ESR remains low (typically under 50 mΩ at 1 MHz) and ESL is in the sub-nH range, supporting effective filtering up to several hundred MHz. The 1206 footprint provides mechanical robustness for hand-prototyping and rework while remaining compatible with high-speed SMT placement.
Typical applications include decoupling and bulk filtering in switch-mode power supplies, snubber and timing networks in lighting ballasts, bypass on industrial PLC and motor-driver boards, DC-link filtering on 24 V industrial buses, and general-purpose coupling/filtering in consumer electronics. The 250 V rating also makes it useful as a coupling element across the primary-secondary barrier in offline flyback converters (subject to safety-agency certification).
A primary design consideration: confirm the actual in-circuit capacitance under DC bias using the manufacturer's K-Sim or similar bias-characterization tool, especially if the design relies on a specific minimum capacitance value. For noise-sensitive analog stages, place a 0.1 µF X7R 1206 close to each IC supply pin in parallel with a smaller (e.g., 10 nF) C0G/NP0 capacitor for high-frequency decoupling.

Aplicações típicas
CL31B104KEHNNNE é adequado para 6 aplicaçãos: Industrial 24V Bus Decoupling, Offline Flyback Snubber / Coupling, LED Lighting Driver Filtering, Consumer Electronics General-Purpose Coupling, IoT Sensor Module Power Conditioning, Automotive Infotainment Auxiliary Rails.
Industrial 24V Bus Decoupling
The CL31B104KEHNNNE's 250 V DC rating provides ample margin over 24 V industrial bus rails, while its 0.1 µF capacitance is the de-facto standard value for local IC supply decoupling. In a typical PLC or motor-driver board, place one CL31B104KEHNNNE within 2 mm of each IC supply pin. The X7R dielectric trades some temperature stability (±15 % across -55 °C to +125 °C) for a small 1206 footprint, which is acceptable on 24 V rails where decoupling is for HF noise suppression rather than precision timing. Samsung's CL31 series Ni/Sn lead-free terminations accept standard +260 °C reflow profiles used on lead-free assembly lines.
Recomendado
Offline Flyback Snubber / Coupling
In offline flyback converters (5-65 W range) the 250 V rating of the CL31B104KEHNNNE allows it to be used as a coupling or snubber capacitor across the primary-side switching node or between primary-side grounds. Its X7R dielectric gives stable behavior over the converter's operating temperature range, and the 1206 (3216 metric) case is small enough for compact adapter designs. Note: this part is NOT a Y1/Y2/X1/X2 safety-rated capacitor - it must not be placed across reinforced isolation barriers. For primary-side snubbing and clamp circuits, the CL31B104KEHNNNE is appropriate; for across-isolation safety coupling, use a certified safety capacitor.
Recomendado
LED Lighting Driver Filtering
The CL31B104KEHNNNE serves as an effective filter capacitor on the DC bus of LED driver circuits, where switching frequencies of 50-200 kHz generate substantial high-frequency noise that must be kept off the LED string. Its 0.1 µF value targets the fundamental switching ripple, and the 250 V rating supports universal-input (90-265 VAC) rectified bus voltages of up to ~375 VDC with derating. The 1206 footprint is small enough to fit inside the dense driver PCBs of commercial downlights and PAR lamps. Pair it with a bulk electrolytic and a smaller 10-100 nF C0G for broadband filtering.
Recomendado
Consumer Electronics General-Purpose Coupling
Across audio-MCU applications, the CL31B104KEHNNNE provides 0.1 µF AC-coupling on signal paths up to several hundred kHz, with 250 V rating protecting against fault voltages from upstream power stages. Its ±10 % tolerance is adequate for non-precision audio coupling (where the listener cannot detect ±10 % gain variation). The 1206 size is convenient for hand-rework and prototype boards. For headphone-amp outputs, where ESR can affect damping factor, the CL31's typical ESR of <50 mΩ at 1 MHz is more than adequate.
Recomendado
IoT Sensor Module Power Conditioning
Battery-powered IoT sensor nodes (BLE/Zigbee/LoRa) using 3.6 V Li-SOCl2 or 3.0 V coin cells typically operate well below the 250 V CL31B104KEHNNNE rating, but the part is still valuable for transient suppression on the input side of boost converters where inductive transients can briefly exceed the supply voltage. The 1206 footprint is small enough for sub-10×10 mm sensor modules. MSL 1 rating simplifies low-volume IoT manufacturing since no dry-pack handling is required before reflow.
Recomendado
Automotive Infotainment Auxiliary Rails
Although the standard CL31B104KEHNNNE is not AEC-Q200 qualified, its 250 V rating and X7R dielectric make it suitable for non-safety automotive applications such as infotainment head-unit power filtering (12 V/24 V systems) and body-electronics auxiliary rails. Designers targeting AEC-Q200 must specify the automotive-grade equivalent (Samsung CL31 series has AEC-Q200 variants under different suffix codes). The 1206 size and standard Ni/Sn termination support the +260 °C reflow profiles used in automotive PCB assembly lines.

Principais diferenciais
- Samsung's general-purpose CL31 series benefits from one of the largest global MLCC manufacturing capacities, ensuring multi-source availability (vs Murata GRM31BR72E104KW01 (7))
- Standard Samsung CL31 part; automotive-grade variants available in the same family with AEC-Q200 qualification (vs KEMET C1206C104KARAC)
- Drop-in interchangeable across Samsung/Murata/KEMET/Yageo with identical 1206 250 V 0.1 µF X7R specifications (vs Yageo CC1206KKX7RYBB104)
Notas de projeto
X7R capacitance drops substantially under DC bias - typically 15-30 % at the rated 250 V. Designers who need a guaranteed minimum 100 nF should consult Samsung's K-Sim tool or the device's bias-characteristic curve. Do not assume 0.1 µF is achieved in-circuit on a 100 V bus - effective capacitance may be only 75 nF. For voltage-critical timing or filter applications, oversize the capacitor or move to a C0G/NP0 dielectric.
Place the CL31B104KEHNNNE within 2 mm of each IC supply pin to minimize parasitic inductance in the decoupling path. Use a land pattern matching the EIA 1206 standard (land width 1.0-1.2 mm, land length 0.8-1.0 mm) to ensure proper solder fillet formation. Avoid placing 1206 MLCCs near PCB screw holes, connectors, or other high-mechanical-stress locations - the ceramic body can flex-crack during depanelization or assembly.
The 1206 CL31B104KEHNNNE is rated for -55 °C to +125 °C operation. For continuous operation above +105 °C ambient, verify with Samsung's high-temperature reliability data. The Ni-barrier + Sn matte-trim termination is rated for +260 °C peak reflow (per JEDEC J-STD-020). Note that this part is MSL 1 (unlimited floor life) per partgenie.ai, so no dry-pack or pre-bake is required before assembly.
