PERFORMANCE

ITEM	PERFORMANCE AND QUALIITY ACCEPTANCE	TEST METHOD
Resistance to temperature coefficient	PPM/℃ ＜ 50PPM	R – RO 106 PPM/℃ = * RO T- T0 R = Measured resistance(Ω)at T T ℃ Ro = Measured resistance (Ω)at To To ℃ T = Measured test temperature(℃) To = Measured base temperature( ℃)
Short time overload	±(0.5%R + 0.05ohm) Shall be no mechanical breakage	AC or DC voltage 2.5times the rated Voltage for 5 seconds .
Voltage endurance	No breakdown or flashover	Lay the resistor on the 90° angle metal “V” peak is 1.42 times as much as insulate voltage .
Terminal strength	Shall be no mechanical breakage	Pull test apply 3.5KG force to the lead in the direction of lead axis for 30±5 seconds.
Heat resistively against soldering	±(0.5%R + 0.05ohm) Shall be no mechanical breakage	Dip the lead in to a solder bath having a temperature of 350℃ ± 10℃ up to 3±0.05mm from the body of the resistor and hold it for 3.5±0.5seconds leave the resistor ,at room temperature 1 hours after ,then Measure.
Load life test	±(1%R + 0.5ohm) Shall be no mechanical breakage	In the constant temperature chamber 70℃ ,apply rated voltage for 1 hour and shut voltage for 0.5 hour and repeat this cycle for 1000 hours,
Solder ability	≥95%	Dip the lead in to a solder bath having a temperature of 260℃±5℃. Time:5± 0.5seconds.
Humidity load test	≤± (2% R+ 0.1ohm) Shall be no mechanical breakage	In temperature chamber 40℃±2℃,relative humidity 90 – 95%,Apply rated voltage 1.5hour and shut voltage 0.5 hour repeat this cycle for 1000 hours, leave in room temperature for 1 hour after test,
Vibration	Shall be no mechanical breakage	set a resistor at the vibration table and vibrate 10HZ—55HZ 10HZ/s. with 1.5mm amplitude in 1 min. when the change of frequency shall be completed uniformly. the vibration shall apply to 3 directions,vertical and horizontal to the axis of resistor each for 3h.
Endurance at upper-limit temperature	≤±(2%R+0.1Ω)	At 125 ℃ temperature, duration of 1000h
