MHR0312SA type
High voltage reisistor
6.1.2 Terminal bend strength
Bend the terminal by 90°in the vertical direction and return to the previous
position under applying a load 5N. This operation is counted once. And repeat a
similar operation in the opposite direction. This operation is counted twice.
One operation must be done in 5 seconds and repeated 4 times.
After bend test, there will be no break and defect in resistor.
6.1.3 Solderbility of terminal
The terminal will be dipped into the methyl alcohol (10weight %～15 weight.%) of
rosin for 2 seconds to 3 seconds. And terminal will be dipped into the solder
bath kept at 230°C+/-5°C for 3 seconds +/- 0.5 seconds.
And then it will be lifted. Lifted speed is 25mm/s +/- 5mm/s.
After testing, a new uniform coating of solder will cover a minimum of 75% of the
surface being immersed.
6.2 Resistance to solvents
After immersing in a isopropyl alcohol at 20°C～25°C for 30 seconds +/- 5 seconds,
raise it slowly.
After testing, no defect in resistor and not to disappear the marking.
6.3 Resistance to soldering heat
The terminal will be dipped into the solder bath kept at 260°C+/-10°C for 10 seconds
+/- 1 seconds.
The resistor will be stored at standard atmospheric conditions for 1 hour～2 hours.
Dipped and lifted speed is 25mm/s +/- 5mm/s.
After testing, change of resistance will be satisfied table 1.
No defect in appearance and satisfied 6.1.1 and 6.1.2.
