PK-11N40PQ

Overview

The PK-11N40PQ is a board-mount piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a continuous tone at a resonant frequency of 4.1 kHz with a tolerance of ±200 Hz. The device is rated for a DC voltage range of 3 to 5 volts and draws a current of 10 mA. It produces a sound pressure level of 83 dB. The unit features solder pin termination for through-hole mounting and has physical dimensions of 14 mm in length, 8 mm in width, and 7.5 mm in height.

Feature Summary

Piezoelectric technology for reliable audible indication
Continuous tone operation for steady state alerts
Through-hole solder pin termination for PCB integration

Applications

Electronic equipment status indication
Consumer appliance signaling
Industrial control panel indicators

Procurement Notes

Verify the specific voltage rating requirements against the datasheet before procurement. Confirm that the operating environment supports the specified temperature range. Ensure the mounting method aligns with the through-hole solder pin design. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate the acoustic output meets the application's audibility needs.

Selection Notes

Select this component when a low-voltage, compact piezoelectric indicator is required. The 3-5VDC range suits battery-powered or low-voltage logic circuits. The 14x8mm form factor allows for space-constrained designs. Consider the 83dB output for environments requiring moderate noise levels. Evaluate the continuous tone characteristic against intermittent alert requirements.

Part Context

This part belongs to the Mallory Sonalert board-mount buzzer series. These devices are designed for direct integration into printed circuit boards. The manufacturer specializes in audio indicators and alarms for industrial and consumer markets. The product line emphasizes reliability and consistent acoustic performance across various operating conditions.
