Overview
The AR01032MR-LWC21-2-R is a round electromagnetic receiver manufactured by PUI Audio, Inc. It features a 32 Ohm impedance and a power rating of 10 mW. The device operates within a frequency range of 300 Hz to 3.4 kHz and delivers a sound pressure level of 114 dBA. Designed for top porting, it has a seated maximum height of 3.30 mm (0.130 inches).
Feature Summary
- Electromagnetic transducer design optimized for audio reception.
- Top port configuration allows for direct sound output from the upper surface.
- Compact form factor suitable for space-constrained electronic assemblies.
Applications
- Consumer electronics requiring high-volume audio alerts.
- Industrial control panels needing audible status indicators.
- Medical devices utilizing compact acoustic signaling components.
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to ensure correct acoustic and electrical characteristics. Confirm RoHS compliance status through current datasheets before integration into regulated products. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a high-decibel output is required in a minimal footprint. The 32 Ohm impedance matches standard driver circuits. Evaluate the 10 mW power handling against the application's drive voltage to prevent thermal damage. Ensure mechanical clearance accommodates the 3.30 mm height constraint.
Part Context
This model belongs to PUI Audio’s general-purpose speaker and transducer lineup. It utilizes Mylar cone materials and neodymium magnets for efficient performance. The product falls under the broader category of audio devices designed for PCB mounting and solder pin termination.
Replacement Considerations
The AR01032MR-LWC21-R shares similar specifications but may lack the specific -2-R suffix variations. Verify dimensional compatibility and acoustic output levels before substituting. Consult official cross-reference lists for confirmed equivalent parts.
