jb JVA - Zinc Oxide Varistors

We design and manufacture high quality Zinc Oxide Varistors Series.  A varistor is an electronic component with an electrical resistance that varies with the applied voltage.
Varistors currently have widespread application in protecting power and signal level electrical circuits against dangerous voltage surges.
Zinc oxide varistors are electronic ceramic materials whose electrical behavior is dominated by grain-boundary interface states.

They exhibit a highly nonlinear current-voltage relation with a 5% change in voltage serving to increase the current flow an order of magnitude or more.

jb Tells You How Does Motor Run Capacitor Work

A motor run capacitor is used to continuously adjust current or phase shift to a motor’s windings in an effort to optimise the motors torque and efficiency performance. 
All run capacitors are designed for continuous duty, and as a result, have a much lower failure rate than start capacitors.

Main Feature:
Motor run capacitors utilize low-loss Metallized polypropylene Zinc aluminum film for dielectric. 
The motor run capacitors are encapsulated with resin and housed in a self-extinguishing plastic case which allows for superior reliability and a high mechanical shock and vibration strength. 

The motor run capacitors is ideal for start and run applications in single-phase asynchronous motors and general A.C. applications at industrial frequencies. 

The motor run capacitor is small in bulk, has long life-span and good self-healing characteristic. 

The motor run capacitor is widely used as the start up and running capacitor that is special for micro water pump, cleaning machine, washing machine, and single-phase water pump motor.
