The Soberton ST-0402T is a surface-mount magnetic buzzer designed for audible indication in compact electronic devices. It operates at a rated voltage of 3V with an operating range of 2 to 4V and draws a maximum current of 90mA under 1/2 duty square wave conditions. The buzzer produces a 4kHz single tone with a sound pressure level of 70dB measured at 10cm.
This externally driven transducer requires an external drive circuit and accepts a zero-peak signal input. The coil resistance is 17 ±3 Ω, and the device is suitable for applications requiring a clear, consistent tone in a small footprint.
The buzzer measures 4.00mm x 4.00mm x 2.00mm and weighs 0.1g. It features a black LCP housing with a top port and solder pad termination for surface mount assembly. It is RoHS compliant and operates over a temperature range of -30°C to 70°C, with storage from -40°C to 85°C.
