Mechanical Characteristics
Item Solderability Evaluation Standard Test Condition 90% min. of the lead terminals Lead terminals are immersed in rosin for will be wet with solder. 5 seconds and then immersed in solder bath (Except the edge of the terminal.) of 270 5C for 3 1 seconds. No interference in operation. Lead terminals are immersed solder bath of 260 5C for 3 1 seconds. No damage or cutting off. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. The buzzer should be measured after applying After the test, the part should a vibration amplitude of 1.5mm with 10 to 55 Hz meet specifications without any damage in appearance or band of vibration frequency to each of the 3 performance. The SPL should be perpendicular directions for 2 hours. within 10 dBA when compared The part should be dropped from a height of to the initial measurement. 75 cm onto a 40 mm thick wooden board 3 times in 3 axes (X, Y, Z) for a total of 9 drops.
