CL10B104KB8NNWC Product Summary

The CL10B104KB8NNWC is a multi-layer ceramic capacitor (MLCC) manufactured by Samsung Electro-Mechanics. Designed in the compact 0603 (1608 Metric) SMD package, this device offers a capacitance value of 0.1 μF (100 nF) with a tolerance of ±10%. Rated for a maximum working voltage of 50V, the capacitor utilizes X7R dielectric material, making it suitable for applications that require moderate stability with respect to temperature and voltage. These features position the CL10B104KB8NNWC as a reliable choice for various digital, analog, and power management circuits in consumer electronics, industrial control systems, and communications equipment.

CL10B104KB8NNWC Physical Structure and Size Specifications

CL10B104KB8NNWC features a robust multilayer ceramic design optimized for surface mounting. The 0603 size (1.6 mm × 0.8 mm) is well-suited for high-density circuit board layouts. The chip is composed of glass epoxy substrate with copper foil and solder resist layers, ensuring mechanical integrity during assembly and operation. Recommended PCB substrate thickness is 1.6 mm for standard sizes, with specialized handling for smaller formats. Soldering termination is designed for reliability under recommended reflow conditions, ensuring consistent placement and adherence on modern PCB layouts.

CL10B104KB8NNWC Electrical Characteristics

The CL10B104KB8NNWC's electrical profile is shaped by its X7R Class II dielectric, offering significant capacitance density and moderate stability across temperature and voltage variations. Key performance characteristics include:

Capacitance and measurement: The specified 0.1 μF is subject to change with variations in applied DC/AC voltage and temperature. Measuring conditions follow EIA RS-198-1-F-2002 and require equipment with Auto Level Control for precise results.

Dissipation factor (Tan δ): As a Class II MLCC, the dissipation factor is a key parameter, which affects energy loss in signal and power applications.

Insulation resistance: The device provides strong leakage protection under rated DC voltage, ensuring circuit reliability.

Aging and temperature coefficients: Capacitance naturally decreases logarithmically over time (aging phenomenon), and temperature can further influence the dielectric constant. Designers must account for these factors in precision or time-dependent applications.

Voltage characteristics: Capacitance diminishes under applied DC bias and AC signals; strict adherence to allowable operating voltage ensures long-term reliability.

Impedance behaviors: At low frequency, the MLCC functions as a pure capacitor; at high frequencies, inductive effects (ESL) dominate, with a distinct self-resonant frequency (SRF).

CL10B104KB8NNWC Environmental and Mechanical Endurance

Samsung CL10B104KB8NNWC undergoes rigorous reliability testing for environmental and mechanical endurance. It is certified to perform at temperatures up to 125°C, a critical threshold for industrial and automotive environments. The device tolerates controlled reflow soldering up to 260°C (peak, 30 sec) and is designed to resist bending, shock, vibration, and piezoelectric effects on a properly designed PCB. Surge voltages, ESD, mechanical shocks, and vibrations require caution; exposure beyond specified ratings may result in insulation breakdown or physical cracking. Use in corrosive or high-humidity environments is not recommended unless protected by design.

CL10B104KB8NNWC Soldering Guidelines and PCB Assembly Methods

Efficient soldering and mounting are vital to the reliability and performance of CL10B104KB8NNWC. Recommended methods include reflow soldering and, for some cases, flow soldering, with strictly controlled temperature profiles (peak: 260°C; reflow not to exceed three cycles). Proper preheating minimizes thermal shock and physical stress on the capacitor. Manual soldering should be limited, with preheat and temperature control to reduce the risk of thermal cracks. Mounting precautions include correct positioning relative to PCB cutouts and screw holes, using gentle pick-and-place pressures (≤300g.f), and supporting substrates to prevent bending. Post-assembly tests should confirm electrical and mechanical integrity, and careful board handling post-soldering is advised to prevent fractures.

CL10B104KB8NNWC Packaging Methods and Storage Instructions

CL10B104KB8NNWC is supplied in standard tape and reel formats following IEC 60286-3 for automated handling and bulk packaging, ensuring safe transit and minimal exposure to damage. The capacitor's shelf life is rated for six months under ideal storage conditions (temperature: 0–40°C; RH: 0–70%). High humidity or temperature accelerates oxidation, reducing solderability. Packaging is designed to protect against transportation shocks and environmental hazards; double boxing and clear labeling aid traceability and inventory management.

CL10B104KB8NNWC Important Design and Application Notes

In engineering applications, the following design aspects are critical when integrating CL10B104KB8NNWC:

Circuit safety: MLCCs may develop cracks due to mechanical or electrical overstress; incorporating fuses or protection circuits is recommended in critical paths.

PCB design: SMD MLCCs are sensitive to stress from bending, dropping, or temperature differences; matching thermal expansion coefficients between PCB and MLCC reduces risk of failure.

Application limitations: Avoid use in aerospace, automotive, military, nuclear, and similar high-reliability applications without consulting Samsung guidance.

Evaluation: Functional verification in the final system is mandatory to account for real-world variations in voltage, temperature, and system-induced surge currents.

Land patterns and soldering: Follow Samsung’s recommended land dimensions and soldering practices to ensure robust joints and to minimize stress during cooling and board separation.

Adhesives and coatings: When used, adhesives and coatings should have thermal, chemical, and mechanical properties compatible with the MLCC; improper selection can degrade performance or induce cracks.

CL10B104KB8NNWC Comparable Alternatives and Substitute Models

Engineers seeking drop-in substitutes for CL10B104KB8NNWC should prioritize devices with matching physical (0603 SMD), electrical (0.1 μF, 50V, X7R), and reliability parameters. Within Samsung Electro-Mechanics’ MLCC portfolio, models such as the CL10B104KB8NNNC may present similar characteristics, subject to verification of tolerance and reliability profiles. Comparable capacitors from other leading MLCC suppliers (Murata, TDK, Taiyo Yuden, AVX/Kyocera) in the 0603 X7R 0.1 μF 50V category are typically suitable replacements, provided that they meet required temperature, voltage, and packaging standards. Key considerations for substitution include aging rate, bias voltage effects, and self-heating behavior.
