Varistor Type MYG
Type MYG Varistors are made of semiconductor ceramic materials composed mainly of
zinc oxide. They have non-linear resistance that changes as a function of applied voltage. It has
small size, high current capacity, and high protection level.
Features
> Wide Varistor voltage range (18V～750V)
> Excellent non-linearity and protection level
> Large withstanding surge current
> Fast response（≤20ns）
Recommended Applications
> Protection of semiconductors
>
> Surge protection of consumer equipment
> Surge protection of communication, measuring or controller instrument
> Relay or electromagnetic Valve surge absorption
