PRODUCT DESCRIPTION
Electrical Characteristics:
Metallized polypropylene film capacitors CBB21/CBB22 (MPP) are non-inductive structures, wound with metallized polypropylene film as the dielectric/electrode, and the wires are made of tinned copper-clad steel wire and sealed with epoxy resin.
High frequency loss is small
Internal temperature rise is small
High insulation resistance, good self-healing, long life
Widely used in high frequency, DC, AC, pulse and S correction circuits

Application Area :
Film capacitors have many excellent properties. Its main characteristics are as follows: no polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and very small dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially in the part where the signals are cross-connected, capacitors with good frequency characteristics and extremely low dielectric loss must be used to ensure that the signal will not be too distorted during transmission.

*FAQ:
Q: What is the difference between CBB21 and CBB81?
A: Although they are both polypropylene film capacitors, the difference between the two is still very large. In some high-voltage and high-current circuits, CBB21 capacitors are no longer competent, so CBB81 has been launched. CBB81 capacitors are made by winding signal sided film, aluminum foil and light film, so their structure is more complicated than CBB21, but it can withstand high frequency, high voltage and high current.
The advantage of CBB81 is that it can withstand high frequency, high voltage and high current, but the disadvantage is that it has small capacity and large volume.
Q: What does the CBB81 capacitor do?
A: CBB81 capacitors are often used in high-pulse, high-current circuits. It can withstand high voltage, high frequency and large current, and is mostly used in resonant circuits. CBB81 capacitors are generally used in electrical appliances that require instantaneous high current. The more common ones are electric mosquito swatters, switching power supplies, ultraviolet disinfection lamps, and ultrasonic mask machine circuits.
