Measuring Circuit Mic: RION S.P.L. meter UC30 or equivalent The current consumption and the sound pressure level are measured by using the recommended driving circuit shown above. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 phone fax page date 3 of 5 11/12/2007 PART NUMBER: CPE-121 DESCRIPTION: piezo audio transducer MEASUREMENT METHOD MECHANICAL CHARACTERISTICS item solderability test condition Stripped wires are immersed in rosin for 5 seconds and then immersed in solder bath of 270 ±5°C for 3 ±1 seconds. 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). No damage or cutting off. lead wire pull strength vibration drop test 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. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 phone fax page date 4 of 5 11/12/2007 PART NUMBER: CPE-121 DESCRIPTION: piezo audio transducer ENVIRONMENT TEST item high temp. test low temp. test humidity test temp. cycle test 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: +95 +25 -40 0.5hr 0.5hr 0.25 0.5hr 3hours 0.5hr 0.5hr 0.25 +25 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. 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.
