Applications

Surge protection in:

consumer electronics

industrial electronics

communication electronics

measuring and controlling systems

electronic home appliances

Protection against surges induced by lighting striking incoming power lines.

Suppression of surges caused by switching inductive loads such as transformers, relays and coils. Protection of rectification diodes, SCRs, power transistors, semiconductor devices, etc.

Definition of Varistor Terms

Rated RMS Voltage, Rated DC Voltage:

The maximum designated values of power system voltage that may be applied continuously between the terminals of a device.

Varistor Voltage: Test characteristic that is used to classify varistors by type. A test current of 1mA DC is typically used to determine varistor voltage classification type. Varistor voltage clamping characteristics can be defined at various test levels.

Rated Peak Single Pulse Transient Current: Maximum surge current, 8/20μs waveform which a varistor is rated to withstand for a single surge.

Rated Single Pulse Transient Energy: Maximum allowable energy for a single impulse (see specified waveforms).

Maximum Clamping Voltage: Measured peak voltage across the device terminals when a current impulse of specified amplitude and waveform is conducted through the varistor.

Typical Capacitance: Typical capacitance values are measured at a test frequency of 1kHz. Capacitance values are only for reference purpose only, not subject to outgoing inspection.
