The discriminator shall be measured after being applied vibration of amplitude of 1.5mm with 10 to 55Hz bands of vibration frequency to each of 3 perpendicular directions for 1 hour. Lead terminals are immersed up to 1.5mm from the discriminator’ s body in solder bath of 350°C ± 10°C for 3 ± 0.5 seconds or 260°C ± 5°C for 10 ± 1 seconds, and then the discriminator shall be measured after being placed in natural condition for 1 hour. Lead terminals are immersed in resin for 5 seconds and then immersed in soldering bath of 250°C ± 5°C for 3 ± 0.5 seconds. 1. After force 10 seconds of 1.0Kg is applied to each terminal in axial direction, the discriminator shall be measured. 2. After lead terminals are fixed at 2mm from the discriminator’ s body, they shall be forced up to 90° from their axial direction and folded back to -90°, then folded back to their axial direction. The speed of folding shall be each 3 seconds. Requirements No visible damage and the measured values shall meet Table 1. The measured values shall meet Table 1. The measured values shall meet Table 1. 95% min. lead terminals shall be wet with solder. No visible damage and the measured values shall meet Table 1. No visible damage and the measured values shall meet Table 1. See Table 2. ENVIRONMENTAL CHARACTERISTICS No. Item 7.1 High Temperature 7.2 Low Temperature 7.3 Humidity 7.4 Heat Shock Phone: +86-10-6301-4184 Condition of Test After being placed in a chamber with +80°C ± 5°C for 96 ± 4 hours and then being placed in natural condition for 1 hour. The discriminator shall be measured. After being placed in a chamber with -20°C ± 5°C for 96 ± 4 hours and then being placed in natural condition for 1 hour. The discriminator shall be measured. After being placed in a chamber with 90 to 95% R.H. at +40°C ± 2°C for 96 ± 4 hours and then being placed in natural condition for 1 hour. The discriminator shall be measured. After being kept at room temperature, the discriminator shall be placed at temperature of -20°C for 30 minutes, then the discriminator shall be immediately placed at temperature of 80°C, after 30 minutes at temperature of 80°C, the discriminator shall be returned to -20°C again. After 5 times above cycles, the discriminator shall be returned to room temperature, after 1 hour in natural condition, the discriminator shall be measured. Vanlong Technology Co., Ltd.
