AS01532MR-R

Overview

The AS01532MR-R is an electromagnetic speaker manufactured by PUI Audio, designed for board mounting applications. It features a round shape with solder pad termination and utilizes Mylar cone material. The unit operates at a self-resonant frequency of 920 Hz with an impedance of 32 Ohms. It delivers a sound pressure level of 85 dB while handling a power rating of 0.5 W. The component measures 15 mm in diameter and 2 mm in depth, weighing 4 grams.

Feature Summary

• Electromagnetic transducer design utilizing Neodymium Iron Boron magnet structure
• Board mount configuration with solder pad electrical termination
• Mylar diaphragm construction for acoustic performance

Applications

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

Procurement Notes

Verify the specific impedance and sensitivity requirements against the system design specifications before procurement. Confirm that the board layout accommodates the required solder pad dimensions and spacing. Ensure the operating environment remains within the specified temperature range to maintain acoustic integrity and prevent material degradation during long-term deployment.

Selection Notes

Select this component when a low-profile, high-impedance speaker is required for space-constrained printed circuit board assemblies. The 32 Ohm impedance suits voltage-driven circuits without requiring heavy current delivery capabilities. Consider the 920 Hz resonance point for tone matching in simple alert or notification systems where broad frequency response is not critical.

Part Context

This part belongs to the AS series of electromagnetic speakers from PUI Audio. The series offers various sizes and impedances tailored for different mounting styles and acoustic needs. The AS01532MR-R specifically addresses applications needing compact form factors with moderate power handling capabilities.

Replacement Considerations

Direct substitutes include other PUI Audio models with similar 32 Ohm impedance and board mount configurations, such as the AS01308MR-R, though differences in diameter and resonance frequency must be evaluated for mechanical fit and acoustic suitability.
