A page 3 of 5 date 02/2008 DESCRIPTION: magnetic buzzer PART NUMBER: CT-1205CL MECHANICAL CHARACTERISTICS item solderability soldering heat resistance terminal mechanical strength vibration drop test test condition Lead terminals are immersed in solder bath of 270 ±5°C for 3 ±1 seconds. The product should follow the reflow temperature curve to test its reflow thermo stability. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. The buzzer will 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 95% of the surface of the lead pads will be wet with solder. test condition After being placed in a chamber at +85°C for 96 hours. After being placed in a chamber at -40°C for 96 hours. The part shall be subjected to 10 cycles. One cycle will consist of: evaluation standard No interference in operation. No damage or cutting off. After the test, the part will meet specifications without any damage in appearance and the SPL should be within ±10% of the i initial measurements. ENVIRONMENT TEST item high temp. test low temp. test thermal shock temp. cycle test The part shall be subjected to 10 cycles. One cycle will last 24 hours and will consist of: After the test, the part will meet specifications without any damage in appearance except SPL. After 4 hours at 25°C, SPL should be within ±10% of the initial measurements. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 rev.

Continuous life test: The part will be subjected to 72 hours of continuous operation at +55°C with 5 V applied. evaluation standard 2. Intermittent life test: A duty cycle of 1 minute on, 1 minute off, a minimum of 10,000 times at room temp (+25 ±10°C) with 5 V dc applied. After the test, the part will meet specifications without any damage in appearance except SPL. After 4 hours at 25°C, SPL should be within ±10% of the initial measurements.
