TFM-23P

Alarms, Buzzers, And Sirens Overview

The TFM-23P is a through-hole piezoelectric buzzer manufactured by East Electronics. It operates at a rated voltage of 9V with a current consumption of 3mA. The device produces an acoustic output of 80dB measured at a distance of 10cm and a frequency of 4kHz. It features PC pins for mounting and includes integrated wiring, with a physical diameter of approximately 16.5mm.

Alarms, Buzzers, And Sirens Feature Summary

• Through-hole construction with PC pin termination
• Integrated wire connection for simplified assembly
• Piezoelectric sound generation mechanism

Alarms, Buzzers, And Sirens Applications

• Indoor alarm systems
• Smoke detector audio indicators
• Carbon monoxide alarm sirens

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'P' against the manufacturer's datasheet to confirm pin configuration and lead type. Ensure the 9V rating matches the target circuit supply. Confirm that through-hole mounting is compatible with the PCB design. Check for RoHS compliance status if required by project specifications.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-current, high-volume audible indicator is required for 9V systems. The integrated wire feature reduces assembly time compared to bare pin variants. Ensure the 80dB output level meets regulatory noise requirements for the intended enclosure size and application environment.

Alarms, Buzzers, And Sirens Part Context

This part belongs to East Electronics' line of piezoelectric buzzers designed for alarm applications. Similar models in the series include the TFM-23 and TFM-25, which may differ in voltage ratings or dimensions. The TFM-23P specifically denotes the version with pre-attached wires for direct connection.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 9V rating, 4kHz frequency, and 80dB output. Verify mechanical compatibility with the 16.5mm diameter and through-hole pitch. Cross-reference with other manufacturers offering equivalent piezoelectric buzzers with integrated leads.
