Perfect for internal installation in a range of devices, these buzzers measure 16.9 mm across and weigh 2.6 g. They come in a square case and are surface-mounted for simple installation.

They've been handled and packed under the ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards for electrostatic discharge. Small buzzers such as this are used in domestic and commercial warning devices such as door alarms or microwaves.
