Such as: display and color display line backhaul line; Electronic ballast, energy-saving lamp
Characteristics of CBB81B High Voltage PPB Plastic Metallized Polypropylene Film Capacitors Box Type
Good self-healing, low loss, high pulse strength and high reliability
Internal series structure, high voltage. Good resistance to high temperature and humidity. Good appearance consistency
Difference between CBB81B capacitor and CBB81 capacitor:
In fact, this capacitor has exactly the same function as CBB81, except that it is protected by a shell. After all, some electrical appliances are used in harsh environments. For example, if they are used outdoors, the stability of the capacitor will be significantly improved and the product life will be significantly longer if a plastic shell is added.
If the environment in which the capacitor is used is not too bad, it is OK to use the CBB81 capacitor. After all, the cost of CBB81 is lower, while the price of CBB81B is relatively expensive. If the cost is not considered, CBB81B is the safest.
