CBB81 High Voltage Metallized Polypropylene Film Capacitors

CBB81 High-Voltage Resonant Capacitor

The CBB81 capacitor, also known as a PPS capacitor, features an epoxy resin encapsulation with a grooved surface. It is designed for high-voltage and high-frequency circuits.

 

Key Features of CBB81 Capacitors:

Metallized Polypropylene Film & Aluminum Foil Construction: Ensures non-inductive structure, high pulse resistance, and high current capacity.

Low High-Frequency Loss: Minimal loss in high-frequency applications (up to 100 kHz).

Strong Overcurrent Capability: Withstands large current surges, ideal for dynamic current conditions.

Low Dissipation & Minimal Internal Temperature Rise.

Applications of CBB81 Capacitors

CBB81 capacitors are widely used in high-pulse circuits and high-current applications, including:

• Mask machines, ultrasonic equipment, large-scale electronic machinery
• UV sterilization lamps, mosquito killer lamps
• High-power power supplies, electronic ballasts

Pin Spacing: 15mm vs. 20mm

CBB81 capacitors are commonly available in 15mm and 20mm pin spacing (distance between leads). Key differences:

• Larger pin spacing typically indicates a larger size, enabling higher capacitance or voltage ratings.
• For the same capacitance, a wider pin spacing generally means higher rated voltage and better voltage margin.
• Under identical capacitance/voltage specs, a larger capacitor offers superior performance, longer lifespan, and higher reliability due to increased voltage margin.
• Trade-offs: Larger sizes require more installation space and incur higher costs
