Lead terminals are immersed up to 1.5 mm from the buzzer’s body in solder bath of 260 ±5°C for 3 ±1 seconds. Apply a force of 9.8 N (1.0 kg) to each terminal in each axial direction. The buzzer will be measured after applying a vibration amplitude of 1.52 mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. The part is to be dropped from a height of 75 cm onto a 40 mm thick wooden board 3 times in 3 axis (X, Y, Z) for a total of 9 drops. Evaluation Standard 90% min. lead terminals should be wet with solder. (Except the edge of the terminal.) Test Condition The part will be subjected to +70°C for 96 hours. The part will be subjected to -30°C for 96 hours The part will be subjected to 10 cycles. One cycle will consist of: Evaluation Standard No in interference in operation. No damage or cutting off. After the test, the part should meet specifications without any damage to the appearance and the SPL should be within ±10 dBA of the initial measurement. Environment Test Item High temp. test Low temp. test Thermal shock Temp./Humidity cycle Phone: 800.275.4899 The part shall be subjected to 10 cycles. One cycle will be 24 hours and consist of: Fax: 503.612.2381 www.cui.com After the test, the part should meet specifications without any damage to the appearance or performance except SPL. After 4 hours at 25°C, the SPL should be within ±10 dBA of the initial measurement. 20050 SW 112th Ave. Tualatin, OR 97062 Date: 9/08/2006 Part No: CEM-1601 Unit: mm Description: magnetic buzzer Page No: 4 of 5 Reliability Tests Item Operating (Life Test) Test Condition 1. Continuous life test: The part will be subjected to 72 hours at 45°C with 1.5 V, 2048 Hz applied. Evaluation Standard 2. Intermittent life test: A duty cycle of 1 minute on, 1 minute off, a minimum of 10,000 times at room temp. (+25 ±10°C) with 1.5 V, 2048 Hz applied. After the test, the part shall meet specifications without any damage to the appearance. After 4 hours at +25°C, the SPL should be within ±10 dBA of the initial SPL.
