Short time overload

 

±(1%R + 0.05ohm)

Shall be no mechanical breakage

 

 

AC or DC voltage 10times the rated

Voltage or 600v, Get the lower voltage. At 5 seconds.

 

Insulation resistance

 

 

﹥500MΩ

 

 

Lay the resistor on the 90° angle metal “V”

Block applies DC 500V voltage for One Minute.

 

Voltage endurance

 

±(0.5%R + 0.05ohm)

Shall be no mechanical breakage

 

 

 

Lay the resistor on the 90° angle metal “V”

Block applies AC 1000V voltage for One Minute.

 

Terminal strength

 

Shall be no mechanical breakage

 

Pull test apply 20N force to the lead in the direction of lead axis for 30±5 seconds.

 

Heat resistively

against soldering

 

 

±(1%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

 

±(5%R + 0.05ohm)

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

 

 

≤± (5% 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.

 

Incombustibility

 

 

Shall be no mechanical breakage

 

 

Resistance by ordinary fire 15 seconds stops for 5 seconds, so loop 5 times.
