Part No: CEP-2202AS Description: piezo audio indicator Date: 9/18/2006 Unit: mm Page No: 3 of 5 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 Lead terminals are immersed in rosin for 5 seconds and then immersed in solder bath of 270 ±5°C for 3 ±1 seconds. Soldering Heat Resistance Lead terminals are immersed up to 1.5mm from buzzer’s body in solder bath of 300 ±5°C for 3 ±0.5 seconds or 260 ±5°C for 10 ±1 seconds. Terminal Mechanical Strength For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. 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 lead terminals 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.

Part No: CEP-2202AS Description: piezo audio indicator Date: 9/18/2006 Unit: mm Page No: 4 of 5 Reliability Test Item Test Condition Operating (Life Test) 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at +70°C with rated voltage applied. 2. Intermittent life test: A duty cycle of 1 minute on, 1 minutes off, a minimum of 5,000 times at room temp (+25 ±2°C) with rated voltage applied. 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.
