after the rated voltage is applied for 2000 hours at 105℃.

Capacitance Change ±20% of the initial measured value.

Tanδ ≦200% of the initial specified value.

Leakage Current

◆ Shelf Life
The following specifications shall be satisfied when the capacitors are restored to

25℃ after exposing them for 500 hours at 105℃ without voltage applied.

The capacitors shall be subjected to voltage treatment specified in item 4.4 of JIS C 5102,

before the measurements.

Capacitance Change ±20% of the initial measured value.

Leakage Current

◆ Solder ability

The lead wires shall be dipped into Methanol (JIS K 1501) or Isopropyl Alcohol (JIS K

1522 or JIS K 8839) solution of 10 ±20% Rosin (JIS K 5902) for 2 ±0.5 seconds, and

then dipped into solder H63A (JIS Z 3282) at 235 ±5℃ for 2 ±0.5 seconds.

The depth of immersion shall be 2 to 2.5 mm of the capacitor body.

≦The initial specified value.

≦The initial specified value.

After immersion, the solder shall cover at least 3/4 of the lead wire surface immersed.

◆ Lead Strength

Pull Strength

The lead wire shall not get loose or cut off, while a parallel force is gradually applied to the

lead wire up to 10N and retained for 10 second.
Bending Strength

Apply the 0.5Kg weight to the end of the lead wire, and lean the capacitors body

90°and return to the original position within approximately 5 seconds.
Then, repeat this cycle in the posited direction at the same speed.
After that, the lead wire shall not loose or cut off.
