Welding

It's tinned evenly

 and with smooth welds,

and the tinned area

95%

Do the test according GB2423-28 of Ta, put welding aid on the  faze end and soaked it into the 230℃ tin solution with  only  5mm distance to the PTC body above the solution, and maintain for 3-5s.

Heat Resistance

Check the variation

rate of resistance

before and after the

test

ΔR/R_n≤20%

Do the test according to GB2423-28 of Tb stsy under the regular temperature and humidity for 4-5 hours, and then check the Rn again.Dipping terminals to a depth of 15mm in a soldering bath of 255℃±10℃,and to the place of 6mm far from PTC boby for 3±0.5s

Intensity at Fuse end

Check the variation

rate of resistance

before and after the

test

ΔR/R_n≤20%

No break out

Do the test according to GB2423-29 of U

Test Ua: Fasten the body and apply a force gradually to each lead until 10N and then keep for 10sec.hold the body and apply a force to each lead until 90° slowly at 5N in the direction of lead axis and then keey for 10sec,and do this in the opposite direction repeat for other terminal.
