AS04008MR-F-2

Overview

The AS04008MR-F-2 is a round, flange-mount general-purpose speaker manufactured by PUI Audio. It features an external diameter of 40mm (1.58 inches) and a maximum seated height of 5.00mm. The unit operates with an impedance of 8 ohms and delivers a sound pressure level of 81dB. Rated input power is 1.0 Watt, with a maximum input capacity of 2.0 Watts. The frequency range spans from 310 Hz to 6 kHz, with a resonant frequency of 580 Hz. Distortion is rated at a maximum of 5%. Operating temperatures range from -25°C to 60°C.

Feature Summary

• Round shape with flange mount design for secure installation
• General-purpose driver suitable for broad audio applications
• Compact form factor with low profile dimensions

Applications

• Appliances
• Industrial controls
• Consumer electronics

Procurement Notes

Verify the specific datasheet version when ordering, as specifications are subject to change without notice. Confirm that the 8-ohm impedance and 1-watt rating align with your circuit requirements. Ensure mounting holes match the flange dimensions. Check environmental ratings if operation exceeds standard temperature ranges. Validate that the 5% distortion limit meets your audio quality standards.

Selection Notes

Select this component for applications requiring a compact, round speaker with flange mounting capabilities. The 8-ohm impedance suits standard amplifier outputs. Consider the 310 Hz to 6 kHz frequency response for general voice or tone reproduction rather than high-fidelity music. The 1-watt power rating limits usage in high-volume scenarios. Evaluate the -25°C to 60°C operating range against your environmental conditions.

Part Context

This part belongs to the PUI Audio AS series of full-range point-source speakers. The series includes various configurations such as different impedances, power ratings, and mounting styles. The AS04008MR-F-2 specifically denotes a 40mm round speaker with flange mounting and 8-ohm impedance. Other variants in the family may offer waterproofing or different electrical characteristics.

Replacement Considerations

Direct substitutes include other PUI Audio models within the AS series with matching 40mm diameter and 8-ohm impedance, such as AS04008MS-3, provided mechanical mounting and frequency response requirements are compatible. Verify dimensional tolerances before substitution.
