CBB81 392J2000V Metallized Polypropylene Film Capacitor For Switching Power Supply

CBB81 392J2000V Metallized Polypropylene Film Capacitor For Switching Power Supply

CBB81 capacitor is a kind of capacitor with metallized polypropylene film and aluminum foil in series, non-inductive winding, and wrapped in epoxy resin. It is very large and can achieve very high voltage, which is the most frequently used capacitor on the high voltage circuit.

Feature

• internal series structure
• low loss at high frequency
• strong overcurrent ability
• high insulation resistance
• long life, stable temperature
• loss Angle tangent decreases with the increase of working frequency

Application:

Electric mosquito bat, Switching power supply, Ultraviolet disinfection lamp, Ultrasonic mask electrical circuit, etc.

What is the role of CBB81 capacitor?

CBB81 capacitors are commonly used in high pulse, high current circuits. It can withstand high voltage, high frequency, large current, mostly used for resonant circuit. CBB81 capacitor is generally used for electrical appliances that need instant surge of high current.

CBB21 and CBB81: Although both are polypropylene film capacitors, there is still a big difference between the two. In some high-voltage and high-current circuits, CBB21 capacitor is no longer competent, so CBB81, a new product, is introduced. CBB81 capacitor is wound by single mask + aluminum foil + optical film, and its structure is more complex than CBB21. But it can withstand high frequency, high voltage, high current.

CBB81 has the advantage of high frequency, high voltage and high current resistance, but has the disadvantage of small capacity and large volume.
