Robustness of
Terminations
(Bending)
The unit shall be secured with its terminal kept vertical and the force
specifi ed below shall 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 po si tion.
The damage of the terminal shall be visually examined.

Vibration
After repeadly applying a single harmonic vibration (amplitude: 0.75
mm, double amplitude: 1.5 mm) 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 ex amined.
Solderability
After dipping the terminals to a depth of approximately 3 mm from the
body in a soldering bath of 235±5°C for 2±0.5 seconds, the terminal
shall be visually examined.
Approximately 95 %
of the termainals shall
be covered with new
solder uni form ly.
Resistance to
Soldering Heat
After each lead shall be dipped into a solder bath having a temperature
of 260±5 °C to a point 2.0 to 2.5 mm from the body of the unit, using
shielding board (t=1.5 mm), be held there for 10±1 s and then be stored
at room temperature and normal humidity for 1 to 2 hours. The change of
