CL21B102JCANNNC

# Product Description: CL21B102JCANNNC The CL21B102JCANNNC is a film capacitor manufactured by Samsung, belonging to the CL21 series of general-purpose film capacitors. This component is designed for use in a wide range of industrial and commercial electronic applications where reliable energy storage and signal coupling are required. Film capacitors like the CL21 series are constructed using a thin dielectric film material wound into a cylindrical form and housed in a protective plastic case. These capacitors are widely recognized for their stability, low self-inductance, and excellent frequency response characteristics, making them suitable for both DC and AC circuit applications. The CL21 series represents a cost-effective solution for applications that do not require specialized high-temperature or high-voltage performance. The CL21B102JCANNNC specifically features a radial lead configuration, which allows for straightforward insertion into through-hole PCB layouts. This design is particularly common in older or established industrial equipment designs, legacy systems, and applications where surface-mount technology is not required or preferred. The component dimensions and lead spacing are standardized within the CL21 family, facilitating easy board layout and replacement. Common application areas for capacitors of this type include power supply filtering, audio frequency circuits, timing circuits, and general-purpose decoupling applications. They are frequently encountered in industrial control systems, consumer electronics, telecommunications equipment, and test instrumentation. Engineers often specify film capacitors in preference to ceramic or electrolytic alternatives when circuit performance benefits from the superior frequency stability and predictable behavior that film dielectrics provide across temperature and frequency ranges. The designation "102" in the part number indicates the capacitance value, following standard electronic color code and numeric conventions. The letter codes and suffix in the full part number denote the voltage rating, tolerance class, and specific packaging options within the CL21 product family. When selecting the CL21B102JCANNNC over alternative capacitor types, engineers typically prioritize the film capacitor's reliability, minimal equivalent series resistance, and consistent electrical characteristics. These attributes make it particularly valuable in circuits where performance stability over time and temperature variation is important, or where the capacitor functions in a signal path rather than purely as a filter element. For design engineers and procurement specialists working with legacy systems or designing new equipment using through-hole component architecture, the CL21B102JCANNNC represents a proven, readily available solution from an established manufacturer.
