Samsung CL10B223KA8NFNC Product Summary

The Samsung CL10B223KA8NFNC is a surface-mount multilayer ceramic capacitor (MLCC) optimized for use in compact and demanding electronic circuits. It features a nominal capacitance of 0.022μF (22nF) with a tolerance of ±10%, a rated voltage of 25V, and utilizes the X7R dielectric in a 0603 (1608 metric) package. X7R capacitors provide balanced performance, offering moderate capacitance stability across a broad temperature range (-55°C to +125°C), making this part suitable for a variety of signal coupling, bypass, and filtering applications.

Structure and Physical Properties of Samsung CL10B223KA8NFNC

Samsung CL10B223KA8NFNC MLCCs are built with a multilayer ceramic structure, ensuring compact size and high volumetric efficiency. The 0603 (1608 metric) footprint is standard for space-constrained designs and enables automated assembly processes. Copper foil is used for terminations, and the recommended substrate material for mounting is glass epoxy, with standard thicknesses of 1.6mm (or 0.8mm for some smaller footprints). The series is designed to meet high reliability standards at elevated operating temperatures (up to 125°C). Advised soldering methodology is reflow soldering, with peak temperature control (260°C ± 5°C for 30 seconds) to maintain mechanical integrity and prevent thermal damage.

Samsung CL10B223KA8NFNC Electrical Characteristics

The electrical characteristics of the CL10B223KA8NFNC are defined primarily by its capacitance, voltage rating, temperature coefficient, dissipation factor, insulation resistance, and impedance profile:

Capacitance stability: X7R dielectric ensures that capacitance remains within ±15% over the specified temperature range, suitable for general purpose filtering and decoupling.

Dissipation factor (DF): This Class II MLCC provides moderate energy loss performance, with DF typically quoted for this category, indicating efficiency in AC coupling and filtering roles.

Insulation resistance: The high dielectric offers low leakage under DC voltages.

Aging: As with all Class II ceramic capacitors, capacitance may decrease logarithmically with time due to material stabilization; recovery occurs after heat treatment.

Voltage characteristics: Capacitance may vary with DC bias and AC voltage, requiring careful consideration in precision circuits. The rated voltage of 25V applies; exceeding this can cause insulation breakdown or failure.

Impedance: The device acts primarily as a capacitor at low frequencies and transitions to inductive behavior at higher frequencies due to equivalent series inductance (ESL). The self-resonant frequency is dictated by component size and structure.

Reliability, Environmental Parameters, and Derating Information for Samsung CL10B223KA8NFNC

Robust reliability testing and guidelines are integral to the CL10B223KA8NFNC’s qualification. Design engineers should implement voltage and temperature derating for prolonged operational life, particularly in high-stress environments. The MLCC should be operated within the defined surface temperature limits (including self-heating from ripple current or pulse loads). Environmental storage conditions should be controlled: 0–40°C temperature, 0–70% RH, avoiding corrosive gases to maintain termination quality. Storage exceeding six months requires solderability checks.

The MLCC’s mechanical resilience is sensitive to board bending, vibration, and shock factors typical in SMD devices. Engineers should evaluate mounting location, vibration exposure, and mechanical handling throughout the product lifecycle. Devices are not designed for use in extreme, safety-critical, or high-reliability applications, such as aerospace or automotive or medical systems requiring direct patient safety.

Guidance on Mounting, Soldering, and Handling Samsung CL10B223KA8NFNC

Optimal performance and reliability require adherence to recommended mounting and soldering practices. Placement should parallel primary stress directions; proximity to board cutouts and screw holes should be minimized to avoid mechanical stress and cracks. Reflow soldering is preferred; observe controlled heating and cooling rates to eliminate thermal shocks. Solder land pattern size and shape directly influence stress transfer to the MLCC, impacting reliability. Excessive pick-and-place pressure (>300g.f.) is discouraged as it may damage the ceramic body. Manual soldering and rework should include thorough preheating and minimal contact time, using lead-free solder compositions as described.

Post-assembly handling, cleaning, and PCB depaneling must minimize mechanical stresses. Strong cleaning vibrations (ultrasonic cleaning) should be tested, and acidic flux residues are to be avoided due to their potential to degrade insulation resistance or cause corrosion. The application and selection of adhesives and conformal coatings must also consider MLCC’s stress sensitivity and compatibility with the ceramic material to prevent resin-induced cracking.

Integration and Circuit Design Details for Samsung CL10B223KA8NFNC

When integrating the CL10B223KA8NFNC into designs, engineers must account for the variable nature of Class II MLCC capacitance under operating conditions, including DC bias, temperature, and aging. For critical applications, perform circuit simulations and system-level testing using actual parts subjected to real-life operating stressors.

PCB layout should minimize stress at the MLCC’s location by using recommended land patterns and ensuring thermal expansion coefficients of board materials are compatible with the MLCC. If used in locations at risk of electrical shorts due to board bending, circuit protection measures (e.g., series fusing) should be considered. These guidelines are essential to prevent insulation breakdown and short-circuit failures.

Samsung CL10B223KA8NFNC Packaging and Storage Details

Samsung CL10B223KA8NFNC capacitors are supplied in various industry-standard tape-and-reel formats for automated SMT assembly. Packaging follows IEC 60286-3 standards to facilitate robotic pick-and-place processes and protect components from mechanical damage during shipping and handling. Cover tape peel-off force is tightly specified to enable reliable automated placement (10g.f. ≤ force ≤ 70g.f.).

Storage prior to assembly should be in controlled environments to guard against oxidation, humidity-induced degradation, and mechanical damage. Long-term storage beyond six months mandates solderability checks.
