PS1240P02BT

Overview

The TDK PS1240P02BT is a round piezoelectric buzzer with a diameter of 12.2 mm and height of 6.5 mm. It operates at a frequency of 4 kHz with a sound pressure level of 70 dBA. The device features a rated input voltage of 3 V and a maximum voltage rating of 30 V. It utilizes through-hole solder pin termination for PCB mounting.

Feature Summary

• Piezoelectric acoustic generation mechanism
• Through-hole solder pin termination style
• Continuous tone output capability

Applications

• General purpose audio indicators
• Equipment status alerts
• Control panel signaling

Procurement Notes

Verify the specific suffix 'BT' to confirm the ammo pack packaging format, as other suffixes may indicate different quantities or reel options. Ensure the 3V nominal voltage aligns with the target circuit design. Confirm RoHS compliance requirements against the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a low-profile 12.2 mm diameter piezoelectric buzzer is required. The 4 kHz frequency provides distinct audible feedback. Consider the 70 dBA output level relative to ambient noise conditions. Verify that the 3V operating voltage matches the available supply rails in the application circuit.

Part Context

This part belongs to the TDK PS series of piezoelectric buzzers. The series offers various diameters and frequencies. The PS1240P02BT specifically addresses applications requiring a compact 12mm form factor with standard through-hole mounting capabilities for industrial and consumer electronics.

Replacement Considerations

The PS1240P02CT3 is a related variant within the same series but differs in physical height (3.5 mm vs 6.5 mm). Substitution requires verification of mechanical clearance constraints on the printed circuit board assembly.
