PK-12N40PEDRQ

Overview

The PK-12N40PEDRQ is a piezoelectric buzzer and sound indicator manufactured by Mallory Sonalert Products Inc. It operates on a 12 VDC supply with a continuous tone frequency of 4.1 kHz. The device produces an acoustic output of 83 dB and draws a current of 10 mA. It features through-hole solder pin termination for PCB mounting. The physical dimensions are 14 mm x 8 mm, with a height of 7.5 mm. The unit is RoHS compliant and designed for general indication applications.

Feature Summary

• Integrates internal drive circuitry for direct connection to DC power sources without external oscillators.
• Provides a continuous single-tone acoustic signal for status indication.
• Utilizes a compact piezoelectric element for reliable operation in standard environments.

Applications

• General electronic equipment status indication
• Control panel audio alerts
• Appliance operational feedback

Procurement Notes

Verify the specific suffix DRQ against official Mallory Sonalert documentation to confirm exact manufacturing revisions or regional compliance variations. Ensure the ordering part number matches the required acoustic and electrical specifications precisely. Cross-reference datasheet parameters such as voltage rating and frequency before procurement to prevent integration errors.

Selection Notes

Select this component when a low-profile, through-hole piezoelectric buzzer is required for 12 VDC systems. The 4.1 kHz frequency offers distinct audibility, while the 83 dB SPL provides adequate volume for most indoor applications. Consider the 14x8mm footprint for PCB layout constraints and verify that solder pin termination aligns with the assembly process.

Part Context
