MECHANICAL CHARACTERISTICS soldering heat resistance terminal mechanical strength vibration drop test Notes: 3 of 5 date 02/2010 DESCRIPTION: piezo audio transducer PART NUMBER: CPE-244 item solderability 1 page test condition Lead terminals are immersed in rosin for 5 seconds and then immersed in solder bath of 270 ±5°C for 3 ±1 seconds. 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 seconds. The force of 9.8 N (1 kg) will be applied for 10 seconds to each terminal in each axial direction. 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 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. 1. Not recommended for wave soldering ENVIRONMENT TEST item high temp. test low temp. test humidity test temp. cycle test 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. 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 02/2010 DESCRIPTION: piezo audio transducer PART NUMBER: CPE-244 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 minute 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.
