The full name of CBB capacitor is metallized polypropylene film capacitor. CBB film capacitors uses metallized polypropylene films as dielectric and is wound into non-conductive structure before encapsulated with resin. It has the advantages of non-polarity, high temperature resistance, small size, wide capacitance range, high insulation resistance, good self-healing property, etc. CBB film capacitors are 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, etc. according to dielectric materials. Different film capacitors have different types, different capacitances, and different volumes. Common CBB capacitors include CBB13 capacitors, CBB20 capacitors, CBB21 capacitors, CBB21X capacitors, and CBB81 capacitors.
CBB13 capacitor: High-voltage polypropylene film capacitor, non-inductive structure, strong overcurrent capability, high insulation resistance, good moisture resistance, excellent frequency characteristics, etc., even at high frequency, the loss is extremely small, suitable for high frequency circuits, high voltage circuits, DC and pulsating circuits.
CBB20 capacitor: Axial metallized polypropylene capacitor, non-inductive structure. Having the characteristics of low high-frequency loss, strong over-current capability, high insulation resistance, etc., used in high-current circuits, widely used in high-current circuits, frequency conversion and frequency division In large pulse circuits, especially in hi-fi frequency divider circuits.
CBB21 capacitor: Metallized polypropylene film capacitor, small size, low high-frequency loss, low temperature rise, good self-healing, widely used in filter circuits, pulse circuits, resonant circuits and coupling circuits; used more often in filter circuits, coupling circuits.
CBB21X capacitor: Small metallized polypropylene film capacitor, because the volume is smaller than the CBB21 capacitor, it can be said to be a reduced version of the CBB21 capacitor, which has the characteristics of high insulation resistance, moisture resistance and self-healing performance. When CBB21 capacitors cannot be used in some circuits due to space restriction CBB21X capacitors can be used.
CBB81 capacitor: High-voltage metallized film capacitor, adopting inner series structure, having the characteristics of small high-frequency loss, strong over-current capability, high insulation resistance, and long service life. It is mainly used in DC, AC and high-current pulsating circuits, frequency converters surge absorption, IGBT protection and other circuits.
The above capacitors are just a few of the CBB film capacitors. There are a large number of film capacitors with different capacitances and sizes, and it is easy to choose the wrong one if you are not careful. Therefore, it is necessary to choose a manufacturer with good reputation. JYH HSU(JEC) (or Dongguan Zhixu Electronics) not only has full models of ceramic capacitors with guaranteed quality, but also offers worry-free after-sales. JEC factories are ISO 9000 and ISO 14000 certified. Welcome to visit our official website: https://www.jeccapacitor.com
