DINGFENG CAPACITOR - - Are cbb capacitors positive and negative?

Issue Time:2020-07-10

CBB capacitors are polypropylene film capacitors and have no polarity. There is no need to distinguish between positive and negative poles. Among the common types of capacitors, only electrolytic capacitors need to distinguish between positive and negative poles. The positive and negative poles are usually marked on the surface, and sometimes they are distinguished by the length of the lead. For common aluminum electrolytic capacitors, the end marked with a white wire on the shell is the negative electrode.


CBB capacitor characteristics


1. No polarity, high insulation resistance, excellent frequency characteristics, and low dielectric loss.

2. High dielectric constant, small size, large capacity and good stability.

3. Small dielectric loss, high insulation resistance, but large temperature coefficient.




▷Suitable for starting and operating 50Hz(60Hz)AC Single-phase household electrical appliances.

▷Widely used as the start-up and running capacitor that is special for micro-water pump,cleaning machines,and single-phase household electrical appliances.




▷Small volume, light weight, low loss, excellent self-healing performance. Copper soldering terminal, plastic coated copper wire and CP wire are available.

▷With its good self-healing characteristic, long-life span and high proportionality, it is widely used as the start--up and running capacitor. That is specially for electric fan, air-conditioner, electric water pump andelectric motor etc.

▷With frequency 50/60Hz, voltage 250VAC, and can help motors start and run.




▷This capacitor takes heavy--edge metalized AL/ZN PP film as dielectric,coiled by high speed winding machine,liquid filled aluminum case and protective device structure with.It is treated by using refined castor oil or wax as an impregnant in the high temperature and vacuum environment to make the capacitor more stable with long working life.Meanwhile based on the principle of safety and proof--explosion,this kind of capacitors has been used the second age mechanical explosion prevent design to strengthen the reliability.The product adopts single and combined structures.

▷The products is suitable for home appliance like air--conditioners,air-coolers,freezers and washing machine.etc




▷This range of capacitor is suitable for fluorescent lamps,high or  low pressure sodium lamps,mercury lamps and metal halide lamps functioned as power factor compensation.They are constructed with self-healing metalized polypropylene dielectric.An attractive feature is the quick fit addition to the mould case.

▷Lamp capacitor or light capacitor is ideally energy-saving lighting capacitor,is non-inductively wound with metalized

polypropylene film as the dielectctric/electrode with encapsulated in a plastic/aluminum case sealed with epoxy resin.
