Solder bath method

Resistance to soldering heat: (Tes�ng method IEC 68-2-20 Tb)

And then the capacitor shall be subjected to standard atmospheric condi�ons for 1 to 2 hours, a�er

which measurement shall be made.

Electrical endurance: (Tes�ng method IEC 60384-2)

125% of category voltage shall be applied to the capacitor at a temperature of 110˚C ±2˚C for 1000

hours. And then the capacitor shall be subjected to standard atmospheric condi�ons for 1 to 2 hours,

a�er which measurement shall be made. The lead resistor in series with the capacitor shall be 20Ω to

1KΩ.

Vibra�on Proof: (Tes�ng method IEC 68-2-6 Fc)

The frequency shall be varied form from 10Hz to 55Hz at 1.5mm amplitude and back to 10Hz in

approximately 1 minute intervals. This mo�on shall be applied for a period of 2 hours in each of 3

mutually perpendicular direc�ons. During the last 20 min of vibra�on in each direc�on, checks shall

be made for open or short-circui�ng and interrup�on.

Damp heat (steady state): (Tes�ng method IEC 69-2-3 Ca)

The capacitor shall be stored at a temperature of 40 ±2˚C and rela�ve humidity of 90% to 95% for

1000 hours.

Performance:

At least 95% of the circumferen�al face of lead wire up to immersed lecvel shall be covered with new

solder.
