4.0 Physical Characterstics

N° Characteristics Test conditions Requirements

4.1 Random Drop The Filter shall be measured after 3 times random drops from the

height of 0.3cm on the concrete floor. No visible damage and the measured values shall meet Table 1.

4.2 Vibration The Filter shall be measured after being applied vibration of the

amplitude of 1.5mm with 10 to 55Hz bands of vibration frequency to each of 3 perpendicular directions for 1 hours. The measured values shall meet Table 1. 4.3 Resistance to Soldering Heat Lead terminals are immersed up to 1.5mm from the Filter’s body in a solder bath of 350 ±10°C for 3 ±0.5 seconds, or 260 ±5°C for 10 ±1 seconds, and then the Filter shall be measured after being placed in natural condition for 1 hour. The measured values shall meet Table 1.

4.4 Solderability Lead terminals are immersed in resin for 5 seconds and then immersed

in a soaldering bath of 235 ±5°C for 2 ±0.5 seconds. 95% min. lead terminals shall be wet with solder.

4.5 Washability Ultrasonic wash not available

5.0 Environmental Characterstics

N° Characteristics Test conditions Requirements

5.1 High Temperature After being placed in a chamber with +85 ±2°C for 96 ±4 hours and

then being placed in natural condition for 1 hour. The Filter shall be measured. No visible damage and the measured values shall meet Table 1.

5.2 Low Temperature After being placed in a chamber with -20 ±2°C for 96 ±4 hours and then

being placed in natural condition for 1 hour. The Filter shall be measured. The measured values shall meet Table 1.

5.3 Humidity After being placed in a chamber with 90 to 95%

R.H. at +40 ±2°C for 96 ±4 hours and then beaced in natural condition for 1 hour. The Filter shall be measured. The measured values shall meet Table 1.

5.4 Heat Shock After being kept at room temperature, the Filter shall be placed at

temperature of –20°C for 30 minutes, then the Filter shall be immediately placed at temperature of 80°C, after 30 minutes at temperature of 80°C, the Filter shall be returned to –20°C again. After 5 times above cycles, the Filter shall be returned to room temperature, after 1 hour in natural condition, the Filter shall be measured. The measured values shall meet Table 1.
