CBB81 High-Voltage Capacitor for Power Supply and High-Frequency Circuit Applications
When it comes to capacitors, few can rival the power and versatility of the CBB81 473J 1000V Capacitor. This exceptional capacitor not only boasts a high voltage rating but can also withstand high frequency and high current levels, making it an essential component in power supply and high frequency circuits.
Exceptional Metallized Polypropylene Film Capacitor for Stable, Long-Lasting Performance
Unlike other polypropylene capacitors, the CBB81 capacitor utilizes metallized polypropylene film as its medium, wound without inductance and encapsulated by epoxy resin. Additionally, it comes with tinned copper-clad steel wire (CP wire) that is radially led out. Its outstanding design, with polypropylene and aluminum foil wound in series, makes it more robust and resilient, allowing it to withstand high voltage with ease.

FAQ — CBB81 473J 1000V Capacitor
Q: 473J code — what value?
A: 47 × 10³ pF = 47 nF = 0.047 µF. J = ±5 % tolerance. 1000 V = working voltage rating.
Q: CBB81 vs CBB22 — interchangeable?
A: Both polypropylene film. CBB81 is higher-voltage / higher-stress rated. Don't downgrade to CBB22 in 1000V positions.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
