DNR VARISTORS
Description
DON’s DNRs are ZINC OXIDE non-linear resistors whose resistance changes as a
function of the applied voltage. The DNR provides a highly reliable and economic way to protect
against repeated high voltage transient and surges such as those produced by induced lightning
surges, switching surges and noise spike.
The DNR utilizes a ceramic element composed of Zinc Oxide and several kinds of metal
oxide additives that have been sintered at relatively highly temperature. Ohmic electrodes are
connected to each end of element by firing.
FEATURES:
Broad products range
Varistor Voltage : 18 V to 1.8 KV
Fast response to the rapidly rising surge voltage (m
Excellent non-linearity voltage
Symmetric V-1 characteristics
Great withstanding surge current
No follow-on current
Long Life
