ALUMINUM ELECTROLYTIC CAPACITORS

◆ Load Life

The following specifications shall be satisfied when the capacitors are restored to 25℃

after the rated voltage is applied for 2000 hours at 85℃.

Capacitance Change

≦±20% of the initial measured value.

Tanδ ≦200% of the initial specified value.

Leakage Current

≦The initial specified value.

◆ Shelf Life

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

25℃ after exposing them for 1000 hours at 85℃ 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.

Tanδ ≦200% of the initial specified value.

Leakage Current

≦The initial specified value.

◆ 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.

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 5N and retained for 10 second.

Bending Strength

Apply the 0.25Kg 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.
