（Mechanical）

Approximately 95% of

the terminals shall be

covered

with solder

uni-formly

Resistance to

Soldering Heat

After each lead shall be dipped into a solder bath having a temperature

260±5℃ (3 series: 250±5℃) to a point 2.0 to 2.5 mm from the body of the

unit, using shieldig board (t=1.5mm), be held there for specified time

(3series: 3±1 s, 5 series: 5±1 s and others: 10±1 s ), and then be stored at

room temperature and humidity for 1 to 2 hours. The change of Vc and

mechanical damages are examined.

△VcmA/VcmA≦±5%

No outstanding

damage

Vibration

After repeadly applying a single harmonic vibration (amplitude: 0.75 mm)

double amplitude:1.5mm with 1 minute vibration frequency cycles (10

Hz to 55 Hz to 10 Hz) to each of three perpendicular directions for

2 hours. Thereafter, the unit shall be visually examined.

Solderadilty

After dipping the terminals to a depth of approximately 3mm from the body

in a soldering bath of 235±5℃ for 2±0.5 seconds, the terminal shall be

visually examined.

Robustness of

Terminations

(Bending)

The unit shall be secured with its terminal kept vertical and the

force specified below be applied in the axial direction.

The terminal shall gradually be bent by 90° in one direction, then 90°in the

opposite direction, and again back to the original position.

The damage of the terminal shall be visually examined.
