Introducción del producto:FS051C223K4Z2A Presentación del producto

The FS051C223K4Z2A is a multilayer ceramic capacitor from KYOCERA AVX’s FLEXISAFE series, designed specifically for safety-critical applications. It combines the award-winning FLEXITERM flexible termination layer with a cascade design structure previously used in high-voltage MLCCs. The FLEXITERM layer protects against board flexure mechanical damage, while the cascade structure prevents low insulation resistance failures from thermal stress damage, repetitive ESD strikes, and placement damage. With 0.022 µF at 100V DC using X7R dielectric, AEC-Q200 qualification confirms automotive-grade reliability for the most demanding safety applications.

Principio de funcionamiento:FS051C223K4Z2A Principio de funcionamiento

The FS051C223K4Z2A operates as a multilayer ceramic capacitor with enhanced safety features:

1. Capacitance: Multiple X7R ceramic dielectric layers interleaved with internal electrodes provide 0.022 µF at 100V rating in a compact 0805 package.

2. FLEXITERM Layer: The flexible termination absorbs mechanical stress from PCB bending, preventing crack propagation from electrode edges into the ceramic body – the primary cause of MLCC field failures.

3. Cascade Structure: The internal cascade design creates multiple isolation barriers within the capacitor, preventing low insulation resistance failures even if micro-cracks form. This protects against thermal stress, ESD damage, and placement damage.

4. Safety Combination: The combination of FLEXITERM and cascade structure provides unbeatable safety features, making FLEXISAFE capacitors the preferred choice for airbag, braking, and steering applications.
