Apply 2.5 times the rated voltage for 5 seconds to each resistor in the network, one at a time.
Maintain at room temperature for 30 minutes after remove the voltage, then measure.
Short Time Overload No noticeable abnormalities in
appearance.
∆R : Within T1.0%
Bend Test
Fix the sample body and apply a load of 10N gradually to the pin in the axial direction.
Maintain the force for 10 seconds.
Bend the pin by 90°in the vertical direction and return to the previous position under applying
a load of 5N. And repeat a similar operation in the opposite direction.
There shall be no broken or loose
pins.
Immerse the pin in melted solder at 260T5Dup to the level of the seating plane of pin for
10T1 second and raise. Then maintain at room temperature for over 1 hour and measure.
Resistance to

There shall be neither mechanical
damage nor noticeable change in
appearance.
∆R : Within T0.5%
Immerse the pin in a flux comprising methanol and resin (weight ratio 25%) up to the level of
the seating plane of pin for 5Y10seconds. Then, immerse in melted solder at 235T5Dfor
2T0.5 second and raise slowly.
Solderability Over 95% of the immersed part of
the pins is covered with new
solder.
Based on JIS C 5202 7.4 After repeating the 5 cycles shown in the table below, maintain at
room temperature for 1Y2 hours, then measure.
