MHR0312SA type
High voltage reisistor
7.3 Short time overload
In standard temperature silicone oil ( or same quality liquid ), the 1.5 times the rated
voltage will be applied for 60 seconds +5/-0 seconds according to the Fig 2.
The measurements of resistance value will be made after leaving under the standard
conditionsfor 1 hour to 2 hours.
After testing, change of resistance value will be satisfied Table 1.
7.4 Pulse characteristics
In standard temperature silicone oil ( or same quality liquid ), resistors will be charged
10,000 pulses +/- 300 pulses of the rated voltage every 6 seconds (on=1 second , off=5
seconds) as the Fig 1 test circuit.
After testing, change of resistance will be satisfied Table 1.
No defect in resistor.
7.5 Thermal shock
Resistors will be exposed to a low temperature of -40°C +0/-5°C for 30 minutes +/- 5
minutes. And then exposed to a high temperature of +100°C +5/-0°C for 30 minutes
+/- 5 minutes.
This constitutes is 1 cycle. Cycles will be repeated 50 cycles.
After testing, change of resistance value will be satisfied Table 1.
No defect in appearance and clacks.
7.6 Humidity storage
Resistors will be exposed to 60°C +/- 2°C and relative humidity 90%～95% for 1000
Hours +/- 12 hours. The measurements of resistance value will be made after leaving
under the standard conditions for 1 hour to 2 hours.
After testing, change of resistance value will be satisfied Table 1.
No defect in appearance.
