Glass Encapsulated TransGuard
Multilayer Varistors
GENERAL DESCRIPTION
The Glass Encapsulated TransGuard® multilayer varistors are
zinc oxide (ZnO) based ceramic semiconductor devices with
non-linear, bi-directional V-I characteristics.
They have the advantage of offering bi-directional
overvoltage protection as well as EMI/RFI attenuation in a
single SMT package.
These large case size parts extend TransGuard range into
high energy applications. In addition the glass encapsulation
provides enhanced resistance against harsh environment or
process such as acidic environment, salts or chlorite flux.
