AS04008PR-WR

Overview

The AS04008PR-WR is an electromagnetic speaker manufactured by PUI Audio, designed for board mounting applications. It features a round shape with a paper cone and neodymium magnet. The unit operates at an impedance of 8 Ohms with a power rating of 1 Watt. Key acoustic parameters include a resonant frequency of 550 Hz and a sound pressure level of 84 dBA. Physical dimensions are specified as 50 mm in diameter, with a depth of approximately 7.2 mm to 10.6 mm depending on specific variant measurements found in related datasheets.

Feature Summary

• Utilizes a paper cone diaphragm for acoustic performance
• Incorporates a neodymium magnet structure
• Designed for direct board mounting installation

Applications

• Consumer electronics audio output
• Industrial control panel signaling
• Medical device acoustic indicators

Procurement Notes

Verify the exact suffix designation (e.g., -WR) against the manufacturer's current datasheet to ensure correct terminal configuration and environmental ratings. Confirm RoHS compliance status through official documentation before integration. Cross-reference physical mounting hole patterns with PCB layout requirements to guarantee mechanical fitment during assembly processes.

Selection Notes

Select this component when a compact 8-ohm round speaker is required for low-power audio applications. The 1-watt rating suits battery-operated devices where efficiency is critical. Ensure the operating temperature range aligns with the intended environment, typically spanning standard commercial ranges. Compare against similar models like the AS05008MR-4-R if higher power handling or different cone materials are needed.

Part Context

This model belongs to the AS series of speakers from PUI Audio, which focuses on electromagnetic transducers for various electronic assemblies. The series offers diverse shapes and sizes to accommodate different enclosure constraints. This specific part represents a standard round form factor commonly used in general-purpose audio signaling tasks within compact electronic housings.

Replacement Considerations

Direct substitutes may include the AS05008PR-WR-R if dimensional compatibility allows for the larger 50mm diameter. Verify impedance and power ratings match the driving circuit capabilities. Check terminal types to ensure solder pad compatibility without requiring adapter hardware.
