PS1927P02

Overview

The TDK PS1927P02 is a piezoelectric buzzer designed for through-hole mounting. It features a 19mm diameter and operates at a resonant frequency of 2700Hz. The device has a rated voltage of 10V and produces a sound pressure level of 90dBA at 10V measured at 10cm distance. The component height is 10.5mm, and it does not include a built-in oscillator circuit.

Feature Summary

• Piezoelectric transducer technology for audio indication
• Through-hole installation style with solder pin termination
• Continuous tone generation capability

Applications

• Consumer electronics audio alerts
• Industrial equipment status indicators
• Data processing unit signaling

Procurement Notes

Verify the specific datasheet version to confirm exact acoustic measurements and electrical tolerances. Ensure the application circuit matches the 10V rated voltage specification. Confirm that the through-hole package dimensions fit the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a high-intensity 90dBA audible alert is required without internal driving circuitry. The 2700Hz frequency provides distinct audibility in noisy environments. Consider the 10.5mm height profile for enclosure clearance requirements during mechanical design integration.

Part Context

This part belongs to the TDK PS series of piezoelectric buzzers. These components are widely used as simple, reliable audio output devices in various electronic assemblies where external drivers can supply the necessary AC signal for sound production.

Replacement Considerations

Check for compatible piezoelectric buzzers with similar 19mm diameter and 2700Hz resonant frequency. Verify that substitute parts maintain the 90dBA sound pressure level at 10V to ensure equivalent performance in the final assembly.
