Multilayer Ceramic Chip Capacitors
CF Series 【RoHS Compliant Products】
■Features
Perform less than 1 fit failure ratio by high voltage durability and high reliability which has optimized internal electrode structure based on designing of safety.
・ Mid-voltage range (Straight structure)
Secure break-down voltage margin with proper suitable dielectric
thickness for each rated voltage.
・ Mid-voltage range (Dual cascade structure）
Achieves high rated voltage by series connection of two capacitor
units in one MLCC to divide applied voltage into two. Also, it has
good protection against transient voltage.
・ Mid-voltage range (Triple cascade structure)
Achieves high rated voltage by series connection of three capacitor
units in one MLCC to divide applied voltage into three. Excellent
safety against high voltage.
The multi cascade design prevents short circuit failure which
results in excellent reliability
■Applications
●Camera/ Strobe circuit, Surge killing, Trigger circui
●LCD back light inverter, Ballast capacitor
●Power circuit/ DC-DC converter, Snubber circuit
