AS04008MR-11-R

Overview

The AS04008MR-11-R is an electromagnetic buzzer manufactured by PUI Audio, Inc. This component operates at a nominal voltage of 3V DC and features a rectangular form factor with dimensions of 25mm in length, 16mm in width, and 8mm in height. It utilizes a through-hole mounting configuration with two pins for electrical connection. The device is designed to produce an audible alert signal within a frequency range centered around 2.7kHz, providing a sound pressure level of approximately 85dB when measured at a distance of 10cm. The unit is constructed with a plastic housing and includes integrated circuitry for self-excited operation.

Feature Summary

• Self-excited electromagnetic design requiring no external oscillator circuit
• Rectangular low-profile housing suitable for space-constrained enclosures
• Through-hole pin configuration for standard PCB assembly processes
• Integrated driving circuitry for direct voltage input operation

Applications

• Consumer electronics audio alerts
• Home appliance status indicators
• Portable device warning signals
• Industrial control panel notifications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the through-hole pin spacing matches the target printed circuit board layout. Check for any recent updates to the RoHS compliance status or material composition declarations prior to finalizing procurement orders.

Selection Notes

Select this component based on the requirement for a self-contained audible alert solution without complex driver circuits. Consider the physical dimensions and mounting style relative to the available space in the final product enclosure. Evaluate the acoustic output requirements against the specified sound pressure level and frequency characteristics to ensure adequate audibility in the intended operating environment.

Part Context

This part belongs to PUI Audio's line of electromagnetic buzzers, which are characterized by their simplicity and reliability in generating audible tones. These components are widely used in applications where a clear, distinct alert is necessary without the complexity of active piezoelectric drivers or microcontroller-based audio generation systems.

Replacement Considerations

Consult official substitution guides from PUI Audio or authorized distributors for verified equivalent parts. Ensure any replacement maintains identical mounting dimensions, pin configurations, and electrical characteristics to guarantee functional compatibility.
