MSE14LDD7

Alarms, Buzzers, And Sirens Overview

The MSE14LDD7 is a miniature board-mount piezoelectric buzzer from the Mallory Sonalert MSE series. It operates on a DC voltage range of 7 to 14 volts with a rated current of 50 mA. The device produces a sound pressure level between 85 and 95 dBA at a frequency of 3.5 kHz, featuring a bell tone pattern. It utilizes solder pin termination for through-hole board mounting. Physical dimensions are 23 mm in length, 23 mm in width, and 14 mm in height, weighing approximately 4 grams.

Alarms, Buzzers, And Sirens Feature Summary

• Integrated internal drive circuitry for direct connection to DC power sources without external oscillators.
• Sealed acoustic design providing consistent audio output performance across varying environmental conditions.
• Through-hole solder pin termination enabling secure mechanical attachment to printed circuit boards.

Alarms, Buzzers, And Sirens Applications

• General purpose audible status indicators in electronic equipment.
• Alarm systems requiring distinct bell tone signaling.
• Control panels and industrial instrumentation interfaces.

Alarms, Buzzers, And Sirens Procurement Notes

Verify exact part number suffixes as variations exist within the MSE series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure operating voltage remains within the specified 7 to 14 VDC range to prevent damage or malfunction. Check availability constraints as distribution channels may report limited stock or discontinuation statuses.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a sealed, high-volume production buzzer with integrated driving electronics is required. The MSE series offers standardized dimensions suitable for compact enclosures. Consider the specific acoustic requirements such as the bell tone characteristic and decibel output levels against alternative signal types like continuous tones or pulses.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE family of miniature piezoelectric buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by low current consumption, robust construction, and integrated driver circuits.
