Voltage of 2.5 times the rated voltage shall be applied for 5
seconds.
Short Time Overload
The attenuator shall be subjected to rated voltage for 90
minutes followed by a pause of 30 minutes at a temperature of
70±3°C. This constitutes 1 cycle. The cycles shall be repeated
for 1,000 hours.
Load Life
The attenuator shall be subjected to rated voltage for 90
minutes followed by a pause of 30 minutes at a temperature of
60±2°C with relative humidity of 90% to 95%. This constitutes 1
cycle. The cycles shall be repeated for 1,000 hours.

cycles.
Resistance to Soldering
Heat
The attenuator shall be immersed into the solder of 260±5°C for
10±1 seconds.
Distance between the fulcrums: 90mm
Bending width: 3mm
Substrate: Glass-Epoxy t=1.6mm

Solderability
The attenuator shall be dipped into the solder of 235±5°C for
3±0.5 seconds. A new uniform coating of solder shall cover
95% or more of surface being immersed.
A new uniform coating of solder shall
cover 95% or ore of surface being
