PS1440P02BT

Overview

The TDK PS1440P02BT is a piezoelectric buzzer designed for through-hole PCB mounting. It operates at a rated voltage of 3V AC and produces a sound pressure level of 75 dBA at a frequency of 4 kHz. The component features solder pin terminals, has a diameter of 14 mm, and belongs to the PS series.

Feature Summary

Piezoelectric transduction mechanism
External drive capability without internal oscillator
Through-hole solder pin termination

Applications

Audio indicators
Alerts
PCB-mounted sound signaling

Procurement Notes

Verify the specific suffix BT against official TDK documentation to confirm terminal plating or packaging variations. Ensure the external driver circuit supports the 3V AC requirement and 4 kHz operating frequency. Confirm RoHS compliance status with the manufacturer before integration.

Selection Notes

Select this component when a compact 14 mm piezoelectric buzzer is required for low-voltage applications. The 75 dBA output provides clear audible alerts. Verify that the application environment accommodates the standard operating temperature range specified in the datasheet.

Part Context

This part belongs to the TDK PS series of piezoelectric buzzers. It shares the external drive architecture with other models in the family but differs in physical dimensions and acoustic specifications compared to variants like the PS1740P02E.
