Product details

30V Very Low Profile Piezo Sounder 4mm

A piezo electric sounder which can supply levels of over 100 dB at a distance of 30 cm, yet is only 4 mm high. It can therefore be used wherever space is at an absolute premium. It requires an external driver which should operate on, or as near as possible to, the buzzer’s resonant frequency of 5,500 Hz. This source should present a maximum drive voltage of 30 V peak-to-peak to the buzzer. 100 mm lead-out wires with tinned ends are provided. Mounting lugs with 2.5mm holes are moulded into the buzzer’s cream-coloured case.
Resonant frequency: 5500Hz ±500Hz
Resonant resistance: 300Ω max.
Electrostatic capacitance: 12000 pF (±30%)
