CX-0905C is magnetic buzzer. ( 9.6 mm, 5 V, 80 dB, 2.7 kHz, Through Hole, Sealed, Driving Circuit )

A Magnetic Audio Indicator Buzzer, also known as a magnetic buzzer or magnetic transducer, is an electromechanical device used to produce sound or audio signals in various electronic applications. Unlike regular piezoelectric buzzers that generate sound using a piezoelectric crystal, magnetic buzzers utilize a coil and a diaphragm to produce sound.

Magnetic buzzers are commonly used in various electronic devices and applications where a simple and compact audio indicator is needed. Some typical uses include alarms, timers, electronic toys, household appliances, and various electronic gadgets. They are relatively easy to drive, as they only require a direct current (DC) input to produce sound.

Mechanical Characteristics

1. Solderability

Lead terminals are immersed in rosin for 5 seconds and then immersed in solder bath of 270 ±5°C for 3 ±1 seconds.

90% min. lead terminals should be wet with solder. (Except the edge of the terminal.)

2. Vibration

The buzzer will be measured after applying a vibration amplitude of 1.5mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours.
