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

Test Conditions
Store varistor at normal room temperature. Dip the varistor leads to solder, at 350P10C for
3P
1
0
seconds,
up
to
2.0K2.5
mm
from
the
varistor
body.
After
that,
store
the
varistor
at
normal room temperature for 30 miniutes, and measure the varistor voltage.
Dip varistor leads to methanol solutin (JIS K 1501, about 25%) of rosin (JIS Z 5902) for 5K10
seconds. Then, dip the lead to solder (JIS Z 3282 H60A or H63A) at 225K240C, up to 2.0K
2.5mm from the varistor body for 5P0.5 seconds. Then, check the solderability.
Fix varistor body, and suspend specified weight toward direction of lead axis.
Lead diameter
F0.6mm, F0.8mm
Force
10 N
The varistor shall be secured with its terminal kept vertical and the force specified below shall
be applied in the axial direction.
The terminal shall gradually be bend by 90 in one direction then back to original position.
The damage of the terminal shall be visually examined.
Lead diameter
F0.6mm, F0.8mm
Force
2.5 N
Mount varistor body on vibrator, and conduct follwing vibration test.
Peak-to-Peak amplitude : 1.5mm
Vibration frequency range : 10HzK55Hz
Sweeping time:
Approximately one minute for 10Hz 55Hz 10Hz
Direction and duration of vibration :
Three directions of X, Y and Z. Two hours each.
Six hours total.
The varistor shall be subjected to 60 second applications of test flame.
Burner : Bunsen gas burner 9000kcal / m3
Diameter of flame nozzle : F9.5 mm
Position : The specimen shall be fixed horizontal.
Point of application shall be approximately center of the specimen.
Specifications
