TM
Compliant
RoHS
Our newly developed TNR SV series is to prevent from being caught fire even very
high surge energy is applied.
Thus electric appliance using TNR SV series can be much safer like TNR SE series.

@Coating
resin doesn't burn under the flammability test of UL.
@Little
scatter at the destruction under over voltage.
@Pb
free for RoHS directives.
@Halogen
free (Coating resin doesn't contain Halogen).
@Strong
to thermal shock (-40C -85C, 100 cycles).
@Safety
approvals (UL, CSA, VDE)
UL1449 File : E95427
