AT-41

Overview

The PUI Audio AT-41 is a general-purpose electromagnetic speaker designed for audio alert applications. It features an 8-ohm nominal impedance and a power handling capacity of 150 milliwatts. The device delivers a sound pressure level of 72 decibels at one meter. Its frequency response spans from 500 Hz to 20 kHz, with a self-resonant frequency of approximately 1400 Hz. The unit utilizes a top-port design for directional sound projection and measures 0.492 inches in diameter.

Feature Summary

• Top-port acoustic design for directed sound output
• Electromagnetic transducer construction
• General-purpose audio alert functionality

Applications

• Electronic device status indicators
• Consumer appliance audio alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific datasheet version for mechanical tolerances and soldering thermal profiles. Confirm that the 8-ohm impedance matches the driving circuit requirements. Ensure the 150 mW power rating is not exceeded during operation to prevent thermal damage. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a compact, low-power speaker is needed for audible feedback. The 8-ohm impedance suits standard driver circuits. Consider the 72 dB SPL for environments requiring moderate volume levels. The top-port orientation dictates mounting constraints relative to the enclosure opening.

Part Context

This component belongs to PUI Audio's line of electromagnetic speakers and buzzers. These devices are commonly used in consumer electronics and industrial equipment where simple, reliable audio signaling is required. The AT-41 represents a standard form factor within their general-purpose product portfolio.

Replacement Considerations
