-40+/-2 ^oC 0.5 hr Ò +25+/-2 ^oC 0.25 hr Ò +85+/-2 ^oC 0.5 hr Ò +25+/-2 ^oC 0.25 hr. Temperature Go up or Drop time is 0.5 hr. 3 hrs per 1 cycle. Total is 5 cycles

*Vibration

1.5mm with 10 to 50Hz of vibration frequency to each of 3 perpendicular directions for 2 hours

*Shock

980m/s² (=100g) shock for each mutually perpendicular directions, half sine wave, 3 times each

*Drop Test

Dropped naturally from 750mm height onto the surface of 10mm wooden board. 2 directions – upper and side of the part are applied

*Soldering Heat Resistance

Pins are immersed up to 1.5mm from sounder’s body in solder bath of 350+/-5 ^oC for 3+/-0.5 seconds

**Solderability

Lead terminals are immersed in rosin for 5 seconds and then immersed in solder bath of 350+/-5 ^oC for 3+/-0.5 seconds.

Warranty

For a period of one (1) year from date of manufacture under normal operations

*All specifications must be satisfied after the test (Recovery:2 to 4 hrs of recovery under the standard condition after the removal from test chamber).

**90% min. soldering pads shall be with solder.(except the edge of pad)
