Murata Manufacturing Piezoelectric Sounder

Low power consumption.
Since it has a non-contact structure, its life is semi-permanent, there is no electrical noise, and there is almost no effect on peripheral circuits.
Compliant with JEITA standard (RC-8180A).
For confirmation sounds of various OA equipment such as copiers, printers and keyboards, household electronic equipment such as microwave ovens and rice cookers, and various audio equipment
- Drop impact and thermal shock can generate surge voltage, so please be careful when designing your circuit. - Applying DC voltage to the main unit can cause silver migration, so please design your circuit so that it does not apply DC voltage. - When driving with an IC, etc., please insert a series resistor of about 1 to 2 kΩ between the IC output terminal and the main unit for stable sound and IC protection, or insert a diode in parallel with the main unit.
