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

1. A surge excess of the specified withstanding surge current may cause short circuits or mechanical breakdown. The
following counter measures re recommended.
1) Location of the over current protector (circuit breaker and current fuse) should be in the power line to the
circuit (Location A) or in series with DNR (Location B).

2) It is recommended that a fuse listed in the table be put in location A or B.
3) In case that DNR is used in line to ground, the ground fault circuit interrupter should be applied in location A
or thermally coupled fuse should be applied in location B.
4) DNR should not be used near the flamable materials.
2. When DNR is molded at end-user, molding resin materials should be carefully selected, otherwise DNR’s long term
stability could degradate.
3. DNR should not be used near heat generating devise and free from direct sunlight. DNR should be used within the
specified operating temperature range.
4. DNR should be free from dust, metal power, dew and sea wind. A protective box is recommended to prevent the unit
from those.
