There is a box-type electronic component with the word CC21 printed on it in red in the electronic circuit, and those who are engaged in the electronic industry or capacitor industry can see it is a CBB capacitor at a glance.
CBB capacitor is a kind of metalized polypropylene film capacitor, which uses metalized polypropylene film as the medium, is wound into a cylinder by non-inductive winding method, and then sealed with epoxy resin of flame retardant material, with the advantages of non-polarity, high temperature resistance, small volume, wide capacity range, high insulation resistance, good self-healing, etc. It is widely used in electronic products.
Film capacitors are divided into different film capacitors according to different categories, such as polypropylene film capacitors, polyester film capacitors, polystyrene film capacitors and so on according to dielectric material. Different film capacitor categories have different capacities and different volume sizes. The common CBB capacitors are CBB13 capacitor, CBB20 capacitor, CBB21 capacitor, CBB21X capacitor, CBB81 capacitor, etc.
CBB13 capacitor: High voltage polypropylene film capacitor, non-inductive structure, with strong over-current capability, high insulation resistance, good humidity resistance and excellent frequency characteristics, the loss is extremely small even in high frequency, suitable for high frequency circuits, high voltage circuits, DC and pulsating circuits.
CBB13 capacitor: High voltage polypropylene film capacitor, non-inductive structure, with strong over-current capability, high insulation resistance, good humidity resistance and excellent frequency characteristics, the loss is extremely small even in high frequency, suitable for high frequency circuits, high voltage circuits, DC and pulsating circuits.
The above capacitors are only a few of CBB film capacitors, and there are many different capacitance sizes and volume sizes of film capacitors, so it is easy to choose the wrong one if you are not careful, so it is good to choose a strong, good reputation and quality capacitor manufacturer when buying film capacitors.
