Measurement frequency : 120Hz
After 1000 hours' application of rated voltage
at 105°C, capacitors meet the characteristic
requirements listed at right.
After leaving capacitors under no load at 105°C for 1000 hours,
they meet the specified value for endurance characteristics listed above.
Resistance to soldering

The capacitors shall be kept on the hot plate maintained at 250°C
for 30 seconds. After removing from the hot plate and restored
at room temperature, they meet the characteristic requirements
listed at right.
