Measuring Circuit Mic: RION S.P.L. meter UC30 or equivalent 2) The current consumption and the sound pressure level are measured by using the recommended driving circuit as shown below. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 www.cui.com For more information, please visit the product page. date 06/2010 page 4 of 5 DESCRIPTION: PIEZO AUDIO TRANSDUCER PART NUMBER: CPE-2883 MECHANICAL CHARACTERISTICS item test condition evaluation standard solderability1 Lead terminals are immersed in rosin for 5 seconds and then immersed in a solder bath of +270 ±5°C for 3 ±1 seconds. 90% min. of the lead terminals will be wet with solder. (except the edge of the terminal) soldering heat resistance Lead terminals are immersed up to 1.5 mm from the buzzer’s body in a solder bath of 300 ±5°C for 3 ±0.5 seconds or 260 ±5°C for 10 ±1 second. No interference in operation. terminal mechanical strength The force of 9.8 N is applied for 10 sec. to each terminal in axial direction. No damage or cutting off. vibration test The buzzer should be measured after a vibration amplitude of 1.5 mm with 10 ~ 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. drop test The buzzer without packaging is subjected to 3 drops on each axis from the height of 75 cm onto a 40 mm thick wooden board. 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. Notes: 1. Not recommended for wave soldering ENVIRONMENT TEST item test condition high temperature test After being placed in a chamber at +95°C for 240 hours. evaluation standard low temperature 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% RH for 240 hours. temperature cycle test The part will be subjected to 5 cycles. One cycle will consist of: 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. RELIABILITY TEST item test condition evaluation standard 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. 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. 2. Intermittent life test: A duty cycle of 1 minute on, 1 minute off, a minimum of 5,000 times at room temp (+25 ±2°C) with rated voltage applied.
