VI Other Performance Of The Preheating Starting PTC Thermistor MZ3

Number	Items	Technical Requirements	Test Conditions
4-1	Appearance	No noticeable defect, such as, bubbles and micro holes, etc; NO visible damage that may reduce its performance; the symbol is clear	Visual Check
4-2	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.
4-3	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
4-4	Intensity of terminal	Check the variation rate of resistance before and after the test ΔR/R_n≤20% No Visual Damage 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.
