The pull force shall be applied to lead wire: Horizontal 3.0N for 30 seconds Vertical 2.0N for 30 seconds 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. 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). test condition After being placed in a chamber at +95°C for 240 hours. After being placed in a chamber at -40°C for 240 hours. After being placed in a chamber at +40°C and 90±5% relative humidity for 240 hours. The part shall be subjected to 5 cycles. One cycle will consist of: evaluation standard 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. ENVIRONMENT TEST item high temp. test low temp. test humidity test temp. cycle test +125 +25 +25 -40 0.5hr 0.5hr 0.25 0.5hr 0.5hr 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. 0.5hr 0.25 3hours 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 For more information, please visit the product page. page 4 of 5 date 11/12/2007 DESCRIPTION: piezo audio transducer PART NUMBER: CPE-827 RELIABILITY TEST item operating (life test) test condition 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.
