AS01008MR-2-R

Overview

The AS01008MR-2-R is an electromagnetic speaker manufactured by PUI Audio, designed for panel mount installation. It features a round shape with SMD/SMT termination and measures 10 mm in diameter and 2.9 mm in height. The unit operates within a temperature range of -20°C to +55°C and utilizes Neodymium Iron Boron (NdFeB) magnets with Mylar cones. Key electrical specifications include an impedance of 8 Ohms, a power rating of 300 mW, and a self-resonant frequency of 1.2 kHz. The acoustic performance delivers a sound pressure level of 86 dBA.

Feature Summary

• Compact form factor suitable for space-constrained panel mounting applications
• Utilizes high-strength neodymium iron boron magnetic structure
• Designed for surface-mount technology integration

Applications

• Panel-mounted audio output devices
• Consumer electronics requiring low-profile speakers
• Industrial control panels with limited depth

Procurement Notes

Verify the specific datasheet version for the AS01008MR-2-R to confirm RoHS compliance details and exact dimensional tolerances. Ensure that the PCB footprint matches the SMD/SMT termination requirements specified in the official documentation. Cross-reference the operating temperature limits against the intended environmental conditions to guarantee reliable performance within the -20°C to +55°C range.

Selection Notes

Select this component when a low-profile, round electromagnetic speaker is required for panel mounting. The 8 Ohm impedance and 300 mW power handling are suitable for low-power audio signals. Consider the 10 mm diameter constraint and verify that the 86 dBA sensitivity meets the application's volume requirements. The SMD/SMT termination method dictates the assembly process compared to through-hole alternatives.

Part Context

This model belongs to the AS series of speakers from PUI Audio, which focuses on compact electromagnetic transducers. The series offers various sizes and shapes, with this specific part representing a small-diameter option optimized for surface-mount integration. It shares design characteristics with other AS series units but is distinct due to its specific dimensions and acoustic ratings.

Replacement Considerations

Check for direct substitutes within the AS series that match the 10 mm diameter and 8 Ohm impedance. Verify compatibility of the SMD/SMT footprint if considering alternative manufacturers. Ensure replacement parts maintain similar sound pressure levels and power ratings for equivalent performance.
