CBT-09427-SMT-TR Description

Short technical summary and product information.

The CBT-09427-SMT-TR is a magnetic buzzer transducer from Same Sky (formerly CUI Devices). It is designed for surface mount assembly with a side sound port, operating as a single tone, externally driven transducer. The buzzer is rated at 3.6V zero-peak signal with an operating voltage range of 2.5 to 4.5V. At rated voltage and 2.73kHz square wave with 50% duty cycle, it produces a sound pressure level of 83 to 87 dBA at 10cm, with typical current consumption of 110mA. The coil resistance ranges from 13 to 19 ohms. The device is housed in a 9.0mm diameter, 2.5mm height package, weighing 0.37g, made of LCP (Liquid Crystal Polymer) with gold-plated solder pad termination. It operates over -40°C to 85°C and stores at the same range. It is RoHS compliant and packaged in tape and reel with 800 units per reel.
