AS04516MR-2-LW105-R

Overview

The AS04516MR-2-LW105-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a 1-watt power rating and a nominal impedance of 16 ohms. The device delivers a sound pressure level of 86 dBA at a resonant frequency of 800 Hz. Physical dimensions are 45 mm in diameter with a depth of 15.5 mm. It utilizes board mount installation with wire lead termination.

Feature Summary

• Electromagnetic transducer design for audio signal reproduction
• Board mount configuration with integrated wire leads
• Compact cylindrical form factor suitable for space-constrained enclosures

Applications

• Industrial control panels requiring audible status indicators
• Consumer electronic devices needing compact audio output
• Medical equipment signaling systems

Procurement Notes

Verify the specific suffix LW105 against official datasheets to confirm wire length and connector type. Confirm RoHS compliance status through current manufacturer documentation. Ensure mounting clearance accommodates the 15.5 mm depth. Validate impedance matching with driving circuits before integration.

Selection Notes

Select this component when a 16-ohm impedance matches the system architecture. The 800 Hz resonance suits applications prioritizing mid-range clarity over wideband fidelity. Consider the wire lead termination method if soldering directly to PCB traces is preferred over pad mounting. Evaluate thermal limits relative to the 1-watt continuous power handling capability.

Part Context

This model belongs to the PUI Audio AS series of electromagnetic speakers. The series typically employs neodymium magnets and mylar cones. The AS04516MR-2 variant indicates a 45 mm diameter frame with 16-ohm impedance. The LW105 suffix denotes specific wire lead specifications.

Replacement Considerations

Cross-reference with AS04516MR-2 for identical electrical parameters without wire leads. Verify dimensional compatibility with existing chassis cutouts. Ensure acoustic performance meets application requirements if substituting with higher sensitivity models.
