CL10B105KA8NNNC Visão geral
A multilayer ceramic capacitor (MLCC) is a passive surface-mount component formed by stacking alternating layers of ceramic dielectric and metal electrodes, then sintering the stack into a monolithic block with metal terminations on both ends. MLCCs sit within the broader passive component hierarchy: capacitor -> ceramic capacitor -> MLCC -> Class II (X7R/X5R) dielectric family. Class II dielectrics such as X7R use high-permittivity barium-titanate-based ceramics to achieve capacitance values many times larger per unit area than Class I (C0G/NP0) types, at the cost of greater capacitance change with temperature, voltage, and age.
Key specifications include 1 uF nominal capacitance at 25 VDC rated voltage, +/-10% tolerance, X7R temperature characteristic (EIA code: X7R = +/-15% delta-C over -55C to +125C), 0603 (1608 metric) case size, and tape-and-reel packaging on a 7-inch reel per EIA-481. The 0603 footprint measures 1.60 mm x 0.80 mm (L x W) with a nominal 0.80 mm height, making the device compatible with standard pick-and-place and reflow processes. The terminations are nickel-barrier with tin (Sn) plating for lead-free reflow soldering.
Architecturally, the device uses Samsung's fine-grained X7R dielectric formulation with internal electrode layers screened to achieve the 1 uF rating within the compact 0603 case. X7R parts exhibit capacitance loss with applied DC bias (DC-bias effect), so the effective capacitance at the rated 25 V is typically 30-50% of the nominal 1 uF value - a key consideration in low-impedance decoupling designs where full 1 uF is assumed.
Typical applications include power-rail decoupling on microcontrollers, FPGAs, and ASICs, local filtering around voltage regulators, AC-coupling and DC-blocking in audio and signal-chain paths, and general-purpose bypass on data lines. The 25 V rating comfortably covers 3.3 V, 5 V, and 12 V rails while leaving margin for transients.
When designing with this part, verify effective capacitance under DC bias using the manufacturer's bias curve, and provide adequate copper land-pad area to absorb thermal and mechanical stress during reflow. Avoid placing the capacitor directly under flex zones or near PCB edges subject to high strain.

Aplicações típicas
CL10B105KA8NNNC é adequado para 7 aplicaçãos: Microcontroller Power Decoupling, FPGA Core Voltage Bypass, DC-DC Converter Output Filter, Audio Signal AC Coupling, USB and Data Line Bypass, Industrial Sensor Signal Conditioning, Automotive ECU Power Rail Filter.
Microcontroller Power Decoupling
The CL10B105KA8NNNC is widely placed adjacent to microcontroller VDD pins as a local decoupling capacitor. Its 1 uF bulk storage combined with 25 V rating easily covers 3.3 V and 5 V rails. The 0603 case size fits standard ARM Cortex and PIC32MZ land patterns with no clearance penalty. Place within 2-3 mm of the MCU VDD pin with a 0.1 uF X7R in parallel to suppress both high-frequency switching transients and mid-frequency load steps, leveraging the 1 uF for energy reservoir during current pulses up to 100 mA.
Recomendado
FPGA Core Voltage Bypass
FPGA cores (PIC32MZ, PolarFire, Spartan, Cyclone) draw dynamic currents up to several amps during logic transitions. The CL10B105KA8NNNC provides local bulk capacitance at each core voltage island. Its X7R classification ensures stable bulk capacitance across FPGA junction temperature rises to 100C. Combined with multiple 0.1 uF X7R capacitors on each supply pin, the 1 uF bulk capacitor handles transient demands that the smaller high-frequency capacitors cannot supply. The 25 V rating gives a 5x derating margin over a 5 V core rail.
Recomendado
DC-DC Converter Output Filter
At the output of switching DC-DC converters (buck, boost, LDO post-filter), the CL10B105KA8NNNC smooths switching ripple and improves transient response. With 1 uF at 25 V, this part handles 3.3 V, 5 V, and 12 V output rails common in industrial designs. Place between the converter output and the load, in parallel with a smaller 0.1 uF cap for high-frequency noise. The X7R dielectric provides stable filtering over temperature variations seen near hot power inductors.
Recomendado
Audio Signal AC Coupling
In audio signal paths, the CL10B105KA8NNNC serves as a DC-blocking capacitor between op-amp stages or at line input/output. The 1 uF value combined with typical 10k-100k ohm input impedance creates a high-pass corner of 1.6 Hz to 16 Hz - well below the audio band. The X7R dielectric introduces minor distortion but is acceptable for consumer audio. For high-fidelity paths, consider a film capacitor instead, but for cost-sensitive consumer products the MLCC works adequately.
Recomendado
USB and Data Line Bypass
USB 2.0, HDMI, and other high-speed data lines require AC-coupling capacitors at the I/O connector. The CL10B105KA8NNNC provides the bulk capacitance for low-frequency line bias while a smaller 0.01 uF cap handles high-frequency content. The 0603 package allows placement close to the connector for minimum stub length and impedance control. With 25 V rating it tolerates the 5 V VBUS line directly without derating concerns in charger-detect circuits.
Recomendado
Industrial Sensor Signal Conditioning
In 4-20 mA current loop receivers, RTD signal conditioning, and analog sensor front-ends, the CL10B105KA8NNNC provides charge reservoir for op-amp stages and ADC reference filtering. The wide -55C to +125C operating range suits outdoor and industrial environments. The X7R dielectric remains stable across the temperature swings common in factory-floor equipment. The 25 V rating comfortably handles industrial 24 V supply rails after the first-stage divider or buffer.
Recomendado
Automotive ECU Power Rail Filter
In automotive ECU designs (under-hood or body control modules), the CL10B105KA8NNNC filters 12 V and 24 V battery rails before downstream regulators. While the standard part is not AEC-Q200 qualified, the equivalent Samsung CL10B105KB8NNNC (50 V variant) is automotive-grade and shares the same 0603 footprint. For non-safety automotive subsystems the standard part is widely accepted by OEMs as commercial-grade. Always verify with your AVL requirements.

Principais diferenciais
- Industry-standard 1uF 25V X7R 0603 with proven high-volume supply (vs GRM188R71E105KA12D)
- Higher voltage margin than 10V X7R equivalent (vs CL10B105KP8NNNC)
- Samsung direct factory supply chain vs distributor-sourced equivalents (vs CC0603KRX7R9BB105)
Notas de projeto
X7R capacitors exhibit significant capacitance loss under DC bias - the CL10B105KA8NNNC's 1 uF nominal drops to roughly 0.5-0.7 uF at the rated 25 V bias. For decoupling applications requiring true 1 uF effective capacitance, either derate voltage to 12 V or below, or specify the 50 V CL10B105KB8NNNC variant which has lower DC-bias loss. Always verify with manufacturer bias curves in critical timing circuits.
Use the recommended 0603 land pattern of 0.85 mm x 0.95 mm pads with 0.40 mm spacing to ensure proper solder joint formation and minimize tombstoning during reflow. Avoid placing the capacitor under flex zones, near PCB edges, or directly under large components that create mechanical stress. For high-vibration applications, add solder fillets at both terminations by ensuring adequate pad area.
Place decoupling capacitors as close as possible (within 2-3 mm) to the IC power pin, with wide, short traces to minimize inductance. For multi-rail ICs, use a 0.1 uF cap directly on each VDD pin plus a shared 1 uF bulk capacitor (CL10B105KA8NNNC) supplying the entire IC. Keep power and ground traces wide and on adjacent layers for low-inductance return paths.
Estimated: at 1 A RMS ripple current in a switching supply, the CL10B105KA8NNNC dissipates approximately I^2 x ESR watts. With X7R ESR of 5-10 milliohms at 100 kHz, dissipation is 5-10 mW - well within the 0603's thermal rating. However, ambient temperature near hot power components can exceed 85C, requiring X7R (not X5R) for stable capacitance over the operating range.
