3 / 4 page Part No: CEP-1172 Description: piezo audio transducer Phone: 800.275.4899 Fax: 503.612.2381 www.cui.com 20050 SW 112th Ave. Tualatin, OR 97062 Date: 6/25/2007 Unit: mm Page No: 3 of 4 Environment Test Item Test Condition High temp. test After being placed in a chamber at +95°C for 240 hours. Low temp. test After being placed in a chamber at -40°C for 240 hours. Humidity test After being placed in a chamber at +40°C and 90±5% relative humidity for 240 hours. Temp. cycle test The part shall be subjected to 5 cycles. One cycle will consist of: Evaluation Standard The buzzer will be measured after being placed at +25°C for 4 hours. The value of the oscillation frequency/current consumption should be ±10% compared to the initial measurements. The SPL should be within ±10dB compared to the initial measurements. Mechanical Characteristics Item Test Condition Solderability Stripped wires of lead wires are immersed in rosin for 5 seconds and then immersed in a solder bath of +230 ±5°C for 3 ±0.5 seconds. Soldering Heat Resistance Lead terminals are immersed up to 1.5mm from insulation in solder bath of 300 ±5°C or 260 ±5°C for 10 ±1 seconds. Terminal Mechanical Strength The force of 9.8N is applied to each terminal in each axial direction for 10 seconds. Vibration The buzzer shall be measured after applying a vibration amplitude of 1.5 mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. Drop Test The part will be dropped from a height of 75 cm onto a 40 mm thick wooden board 3 times in 3 axes (X, Y, Z) for a total of 9 drops. Evaluation Standard 90% min. of the stripped wires will be wet with solder. (Except the edge of the terminal) No interference in operation. No damage or cutting off. The value of oscillation frequency/current consumption should be ±10% of the initial measurements. The SPL should be within ±10dB compared with the initial measurement. |
