METAL OXIDE VARISTORS TNR^®

When the surge energy much higher than the rated maximum energy is applied to the

varistors, it may blow up and catch fire.

Our newly developed TNR SE series is to prevent from being caught fire even very high

surge energy is applied.

Thus electric appliance using our TNR SE series can be much safer.

?FEATURES

@Newly developed non-flammable material (Harogen Free) is used for outer coating.

@The new outer coating will meet UL flammability test.

@At the over voltage test, the new material shall deter burning caused by the high temperature,

arc and the large surge current when TNR shall blow up.

@General specifications are same as that of V series, large surge capability TNR.

?APPLICATIONS

@Protection for semiconductors from over voltage.

@Protection for electronic instruments from lightning surge.

@Absorption of on-off surge from motors and relays.

Operating Temperature Range: -40K+85C

Storage Temperature Range: -50K+125C
