AS04304PR-F-WP-R

Overview

The PUI Audio AS04304PR-F-WP-R is a general-purpose electromagnetic speaker designed for board or bare mounting applications. It features a round chassis with an external diameter of 42.5 mm and operates within a frequency range of 180 Hz to 20 kHz. The unit has a nominal impedance of 4 ohms and supports a nominal power rating of 3 W, with some sources indicating a 5 W capacity. It delivers a sound pressure level of 85 dB.

Feature Summary

Round chassis design suitable for general-purpose audio output
Supports both board mount and bare mount installation methods
Top-port configuration for direct sound projection

Applications

Consumer electronics devices requiring compact audio feedback
Industrial control panels needing audible status indicators
Medical equipment utilizing standard acoustic signaling

Procurement Notes

Verify the specific datasheet version to confirm whether the power rating is 3 W or 5 W, as documentation varies. Ensure the selected package matches the required mounting style, either board mount or bare mount. Confirm RoHS compliance details are current for the manufacturing batch. Cross-reference the impedance value of 4 ohms with circuit requirements before integration.

Selection Notes

Select this component when a round, general-purpose speaker is required for low-to-mid volume applications. The 4-ohm impedance suits standard amplifier outputs. Consider the physical dimensions of 42.5 mm diameter against available enclosure space. Evaluate the 85 dB sensitivity against ambient noise levels in the target environment.
