Samsung Electro-Mechanics CL10B104KA8NFNC

CL10B104KA8NFNC Multilayer Ceramic Capacitor Product Summary

The Samsung Electro-Mechanics CL10B104KA8NFNC is a surface-mount multi-layer ceramic capacitor (MLCC) representing the ubiquitous 0.1 μF (100 nF) X7R dielectric in a 0603 (1608 metric) package. With a rated voltage of 25 VDC and ±10% tolerance, this MLCC targets a broad spectrum of applications, from signal coupling/decoupling and bypassing to timing circuits and EMI filtering. Thanks to its combination of reliability, compact size, and excellent electrical stability, the CL10B104KA8NFNC is a leading choice for dense, high-performance electronic designs.

Principal Electrical Specifications of the CL10B104KA8NFNC

A thorough understanding of electrical specifications is vital for effective component selection. The CL10B104KA8NFNC offers:

Capacitance: 0.1 μF (100 nF), measured under standardized conditions aligned with EIA RS-198-1-F-2002.

Rated Voltage: 25 VDC maximum, suitable for a wide range of logic, analog, and power applications.

Dielectric Type: X7R (Class II), providing moderate capacitance change over temperature but with stable properties for general-purpose use.

Tolerance: ±10%, ensuring sufficient precision for decoupling networks and waveform-shaping applications.

Package: 0603 (1.6 mm × 0.8 mm), supporting compact PCB layouts and automated assembly lines.

Dissipation Factor (DF or Tan δ): Characteristic of Class II ceramics, the DF is a measure of energy loss. For filter, coupling, or timing circuits where loss parameters are essential, verify application-specific DF requirements.

Insulation Resistance: Typically very high for MLCCs, ensuring minimal leakage in signal paths.

Self-heating & ESR: Like all MLCCs, self-heating under AC/ripple current loads must be considered, with the requirement that the component temperature does not exceed +125°C (including self-heating effects).

Capacitance Variation Due to Voltage, Temperature, and Aging in the CL10B104KA8NFNC

Capacitance in Class II MLCCs such as the CL10B104KA8NFNC is not constant; three primary influences must be considered:

Voltage Effects: Both DC bias and AC voltage can cause variations in capacitance. When deployed in supply rails or timing circuits with narrow design margins, engineers should test under actual operating voltages to guarantee functional integrity.

Temperature Characteristics: The X7R dielectric ensures that capacitance remains within ±15% over the temperature range –55°C to +125°C. For applications experiencing temperature swings, such as automotive or industrial environments, this characteristic is crucial for maintaining performance consistency.

Aging Effects: Capacitance decreases logarithmically with time—regaining its value after exposure to elevated temperatures (e.g., reflow soldering). While aging is a natural process in high-K ceramics, it is essential to account for this drift in long-lifetime designs.

Physical and Environmental Requirements for the CL10B104KA8NFNC

Though MLCCs are robust electrically, their ceramic bodies are mechanically sensitive:

Vibration & Shock: Excessive vibration or board flexing can induce cracks. For high-vibration environments, special versions with soft terminals are recommended.

Piezo-electric Effect: X7R capacitors may emit audible noise under AC excitation—critical in audio or user-facing designs.

Corrosive Atmospheres: Exposure to high humidity or corrosive gases may lead to termination degradation, reducing solderability or performance.

In engineering practice, proper component placement (away from board edges, cutouts, and mounting holes) and mitigation of excess mechanical and thermal stress are essential.

Guidelines for Mounting, Soldering, and PCB Layout of the CL10B104KA8NFNC

SMD MLCCs such as the CL10B104KA8NFNC require precise handling during assembly:

Recommended Soldering: Reflow is preferred, with a peak soldering temperature of 260°C (±5°C) for a maximum of 30 seconds. Excessive temperature or reflow cycles can introduce cracks, especially in ultra-miniature or high-capacitance designs.

Solder Volume: Both underand over-soldering can compromise mechanical attachment. The correct pad design, based on Samsung's recommendations, is critical.

Pick-and-Place: Nozzle pressure should not exceed 300g.f. Nozzle cleanliness and maintenance are necessary to avoid excess force and cracks.

Board Design: SMD capacitors are more stress-sensitive than leaded components. Differences in thermal expansion between substrate and capacitor should be minimized.

When adding adhesives or coatings, select materials with compatible thermal expansion coefficients and follow correct application and curing guidelines to avoid damaging stresses.

Procedures for Storage, Handling, and Quality Control of the CL10B104KA8NFNC

Storage: Store the CL10B104KA8NFNC at 0–40°C and RH≤70% to prevent oxidation of termination finishes and preserve solderability. Ideally, components should be utilized within six months of delivery.

Handling: Prevent mechanical damage by avoiding board flex or shock during population, soldering, or post-soldering assembly stages. Do not handle MLCCs with bare hands during operation to avoid ESD risks.

Quality Assurance: Standard reliability testing is performed per manufacturer’s protocols, but system-level evaluations—especially surge resistance, vibration, and capacitance drift—should be completed as part of the customer’s validation process.

Alternative and Substitute Models for the CL10B104KA8NFNC

If supply constraints or design changes require cross-referencing, the following product criteria assist in identifying suitable alternatives:

Dielectric Type: X7R or equivalent

Capacitance Value: 0.1 μF (100 nF)

Voltage Rating: 25V minimum

Package Size: 0603 (1608 metric)

Tolerance: ±10%

Equivalent models could include:

Murata GRM188R71E104KA01D

TDK C1608X7R1E104K

AVX (Kyocera) CM105X7R104K25AT
