MSE28MDP3

Alarms, Buzzers, And Sirens Overview

The MSE28MDP3 is a piezoelectric buzzer from the MSE series by Mallory Sonalert Products Inc. It features internal drive circuitry and operates on DC input within a voltage range of 16 to 28V. The device draws 50mA of supply current and produces a slow double pulse tone at a frequency of 3.9kHz with a repetition rate of 0.5 pulses per second. It delivers an acoustic output of 85dB SPL measured at 20V and 30cm distance. The unit utilizes through-hole PC pin termination for board mount installation and measures 23.00mm x 23.00mm in size.

Alarms, Buzzers, And Sirens Feature Summary

• Automotive dashboard alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the exact part number MSE28MDP3 against manufacturer documentation to ensure correct tone configuration. Confirm that the required slow double pulse characteristic matches system design specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure voltage ratings align with the target circuit's DC supply levels before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact board-mount solution requires a unique double-pulse warning signal. Compare against standard continuous tone buzzers if specific auditory differentiation is necessary for safety protocols. Consider the 50mA current draw for power budget calculations. Evaluate the 23mm square footprint against available PCB real estate constraints during the layout phase.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE series of miniature board-mount buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by small form factors suitable for dense electronic assemblies. These devices are engineered for general-purpose audio indication in commercial and industrial electronics, offering various tone options within a standardized physical package.

Alarms, Buzzers, And Sirens Replacement Considerations

MSE28LDP3S provides a similar slow pulse format but differs in specific waveform characteristics. MSE28LCH2 offers a chirp tone variant within the same physical envelope. Verify electrical parameters and acoustic output levels when substituting to maintain system performance integrity.
