ASE02008MR-LW150-R

Overview

The ASE02008MR-LW150-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a 20 mm square form factor with a top-ported design and integrated 150 mm lead wires for direct circuit connection. The unit operates at an impedance of 8 Ohms with a rated power handling of 500 mW. Acoustic performance includes a sound pressure level of 79 dBA and a resonant frequency of 500 Hz. The diaphragm utilizes Mylar material, supported by a Neodymium Iron Boron magnet assembly.

Feature Summary

• Integrated 150 mm lead wires facilitate immediate board integration without additional wiring harnesses.
• Top-ported acoustic architecture optimizes sound projection directionality.
• Square physical footprint allows for efficient utilization of constrained enclosure spaces.

Applications

• Consumer electronic devices requiring compact audio output
• Industrial control panels needing audible status indicators
• Medical equipment with limited internal volume constraints

Procurement Notes

Verify the specific lead wire length and termination type against the current official datasheet before finalizing the design. Confirm that the 150 mm leads meet the mechanical routing requirements of the target enclosure. Ensure the 8 Ohm impedance matches the driving circuit specifications to prevent potential overload or insufficient drive levels during operation.

Selection Notes

Select this component when space efficiency is critical due to its square geometry compared to round alternatives. The pre-attached leads simplify assembly processes but require adequate clearance within the housing. Consider the 79 dBA output level to ensure it meets the required audibility standards for the intended application environment without necessitating amplification.

Part Context

This model belongs to the AS series of electromagnetic speakers from PUI Audio, Inc., which are characterized by their compact dimensions and standardized mounting interfaces. The series typically employs Mylar cones and NdFeB magnets to deliver reliable audio performance in small form factors suitable for portable and embedded electronics.

Replacement Considerations

Direct substitutes may include other 20 mm square speakers with similar impedance and power ratings. Verify compatibility regarding lead wire presence, as many standard replacements require separate wiring. Check if alternative models offer higher sensitivity or different port configurations if acoustic performance adjustments are necessary.
