1. SMD PIEZO TOP SOUNDS BUZZER Description

The buzzer is an electronic sounder with an integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products . The buzzer is mainly divided into two types of piezoelectric buzzer and electromagnetic buzzer. The buzzer is represented by the letter "H" or "HA" in the circuit (the old standard is "FM", "ZZG", "LB", "JD", etc.).

Test circuit Test device

The resonant frequency is a square wave with a 50% duty cycle, and the signal voltage must be sufficient to allow the transistor
to saturate.

Frequency response curve

In a square wave with a 50% duty cycle at 3Vo-p, the test distance is 10cm

Reflow soldering conditions:

a.Reflow soldering curve

Note: (1) After the product passes through the reflow soldering machine, all electrical properties should be kept within the
specifications.
(2) The operating temperature of reflow soldering must be within the recommended range. If it exceeds the range, it may affect the performance of the product.
