CBB capacitors are non-inductive, using polyester film as the dielectric and aluminum foil as the electrode winding, tinned copper-clad steel wire, and epoxy resin encapsulation.

1. CBB capacitor stability and reliability;

2. Non-inductive structure reduces the loss factor to a low level;

3. Excellent environmental performance.

4. ESR is low.

CBB capacitors are ideal for commercial equipment that requires small signal circuits that reduce noise.


Metallized film capacitors have high resistance, have good solderability and self-recovering properties, and save space in a small size.



1. Working temperature: -40 ℃ ~~ + 85 ℃;

2. Capacitance range: 0.01UF ~~ 10UF;

3. Capacitance tolerance: ± 5 (J), ± 10 (K), ± 20 (M);

Rated voltage: 100V, 250V, 400V, 630V;

Loss tangent angle: 1% (max) at 1KHz;

Withstand voltage: Teminal to (at20 ± 5 ℃).

This product is suitable for coupling, filtering, rectifying and timing circuits, and is widely used in remote communication, data processing, industrial instrumentation and automatic control system equipment.


Film capacitors are excellent capacitors because they have many excellent characteristics. Its main characteristics are as follows: non-polar, high insulation resistance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially in the part where the signal is connected, a capacitor with good frequency characteristics and extremely low dielectric loss must be used to ensure that the signal does not have too much distortion when it is transmitted. Among all plastic film capacitors, the characteristics of polypropylene (PP) capacitors and polystyrene (PS) capacitors are significant, and the unit price is also relatively high.
