The SMTB-0927-TW-R is an electro-mechanical transducer designed for audio signaling. It operates on a rated voltage of 3 Vo-p with a range of 2 to 5 Vo-p, drawing a maximum rated current of 80 mA. This transducer produces a minimum sound pressure level of 95 dBA at 10 cm, with a resonant frequency of 2,700 ± 200 Hz. Constructed with an LCP housing and weighing only 0.4 grams, it is built to withstand a wide operating temperature range of -40°C to +105°C, making it suitable for demanding applications requiring an audible alert.
