Samsung Electro-Mechanics CL10B102KB8NFNC

CL10B102KB8NFNC Samsung Electro-Mechanics Product Summary

The CL10B102KB8NFNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung Electro-Mechanics, designed for high-volume, reliability-focused surface-mount applications. Offering a capacitance of 1000 pF (1 nF) with a ±10% tolerance, this device supports a maximum working voltage of 50V and uses the X7R Class II dielectric for stable temperature characteristics. Packaged in the compact 0603 (1608 metric) case size, the CL10B102KB8NFNC is engineered to address the high-density circuit demands in telecom, computing, consumer electronics, and general-purpose SMT board designs.

Physical Features and Measurements of CL10B102KB8NFNC

Physically, the CL10B102KB8NFNC is offered in the standardized 0603 surface-mount format (1.6 mm × 0.8 mm nominal footprint), supporting automated assembly processes. The construction leverages a multilayer ceramic design, stacked to achieve the rated capacitance and voltage, with nickel-barrier terminations for robust soldering and minimized ESR. The thin-package profile makes it suitable for high-density PCB layouts. Structural reliability is ensured through testing—such as adhesion, bending, vibration, and shock—typically carried out on glass epoxy test PCBs with 1.6 mm thickness (or 0.8 mm for smaller chip sizes) and standard copper foil.

Key Electrical Specifications of CL10B102KB8NFNC

The CL10B102KB8NFNC’s key electrical specifications include a nominal capacitance of 1000 pF, ±10% tolerance, and a 50V DC rating. The X7R dielectric ensures minimal capacitance drift within ±15% over the -55°C to +125°C range, supporting use in temperature-variable environments. Dissipation factor (tan δ, DF) and insulation resistance meet or exceed EIA RS-198-1-F-2002 standards. The MLCC exhibits low ESR and moderate Q, balancing energy storage efficiency and dielectric loss for decoupling, filtering, and signal coupling/decoupling circuits.

Impedance characteristics of the CL10B102KB8NFNC follow the expected curve for MLCCs: capacitive reactance dominates at low frequencies, with a transition to inductive behavior above the self-resonant frequency. Engineers should factor in the effect of frequency on impedance and ESR, especially for high-frequency applications.

Temperature, Aging, and Voltage Behavior of CL10B102KB8NFNC

The X7R dielectric class used in CL10B102KB8NFNC provides stable capacitance over a broad temperature range, with a maximum temperature coefficient of ±15%. As with all Class II ceramics, designers should account for small but significant changes in capacitance with applied DC bias and gradual capacitance age-down (logarithmic loss over time), particularly after initial heat treatment cycles; these effects are typically recoverable or manageable through suitable design margin.

The rated voltage of 50V DC must not be exceeded in either normal operating conditions or under combined DC+AC stress. Capacitance tolerance narrows under high DC bias or at temperature extremes, so critical applications should confirm stability against system voltage and ambient variations. Self-heating effects may arise under large ripple or pulse current; keep the surface temperature rise by self-heating below 20°C to maintain long-term reliability.

Installation and Soldering Procedures for CL10B102KB8NFNC

Proper mounting and soldering are vital to preserve the CL10B102KB8NFNC’s electrical and mechanical integrity. Reflow soldering is the recommended process, with a peak temperature of 260 ± 5°C for 30 seconds maximum. Adherence to the recommended solder land patterns and controlled solder paste quantity are crucial to avoid mechanical stress cracks and ensure reliable electrical connection. Both insufficient and excessive solder can compromise joint reliability—leading to either poor adhesion or excessive stress, respectively.

When using SMT pick-and-place equipment, the maximum mounting pressure should not exceed 300 g.f to prevent internal or surface cracks. For flow soldering or manual touch-up, preheating of components and PCB is essential to mitigate thermal shock. After soldering, allow for natural air cooling rather than forced cooling to reduce the risk of cracking. Handle boards by the edges, and avoid direct contact with the ceramic body using soldering iron tips. Special attention should be paid when cutting or handling the PCB after MLCC assembly, as board flexure can induce mechanical cracks.

Storage Requirements and Environmental Factors for CL10B102KB8NFNC

For optimal shelf life and solderability, the CL10B102KB8NFNC MLCCs should be stored at temperatures between 0–40°C and relative humidity under 70%. Storage beyond six months warrants rechecking solderability before use. The storage environment must be free from corrosive gases and sharp humidity fluctuations to prevent termination degradation or moisture-induced issues. During transportation, protection from excessive force, vibration, and environmental extremes is required to prevent microcracking or damage.

Engineering Advice and Recommended Practices for CL10B102KB8NFNC

Engineers must consider derating the applied voltage according to actual operating temperatures to maintain long-term reliability, especially in high-temperature or variable environments. The device is not rated for direct use in life-critical or high-reliability fields like aerospace, automotive, or military applications; when needed for such, consult Samsung’s application engineers for specialized solutions.

Attention should also be paid to potential mechanical resonance, piezoelectric noise in AC/pulse applications, and stress from PCB mounting near cutouts or screw holes. During circuit design and assembly, safety measures such as fusing in parallel with the CL10B102KB8NFNC are advised to guard against rare but possible short-circuit conditions resulting from insulation failure after board flex, shock, or surge.

Alternative and Substitute Models for CL10B102KB8NFNC

When sourcing or qualifying alternatives for the CL10B102KB8NFNC, engineers should match key criteria: capacitance value (1 nF), tolerance (±10%), voltage rating (50V), dielectric type (X7R), case size (0603), and similar or superior ESR/IR characteristics. Several leading MLCC manufacturers, including Murata (GRM series), TDK (C series), AVX (0603YC series), and Yageo (CC0603KR series), provide suitable equivalents. When considering drop-in replacements, verify footprint compatibility as well as process compatibility (tape/reel packaging, solderability, and test conditions). Engineering validation is always recommended to ensure equivalence not only in specification, but also in long-term reliability and mounting behavior under actual application conditions.

Conclusion

The CL10B102KB8NFNC from Samsung Electro-Mechanics is a robust, high-density MLCC providing stable capacitance, reliable performance, and SMT process compatibility for a wide range of industry applications. Proper understanding and management of its storage, mounting, thermal, and electrical nuances—alongside prudent verification during product selection or substitution—ensure its successful and reliable integration into demanding modern electronic systems. For product selection engineers and procurement professionals, a systematic approach to qualification and lifecycle management will maximize the value and performance of the CL10B102KB8NFNC and its possible replacements.
