RAB-32063-P143

Speakers Overview

The RAB-32063-P143 is a rectangular balanced armature receiver manufactured by Knowles Electronics. It features a compact form factor with dimensions of 5.15 mm in length, 3.20 mm in width, and 2.58 mm in depth. This component is designed as a general-purpose speaker suitable for applications requiring high sound quality within small enclosures.

Speakers Feature Summary

• Rectangular balanced armature design optimized for space-constrained environments
• Excellent bandwidth performance relative to its physical size

Speakers Applications

• General purpose audio receivers
• Midrange or tweeter drivers in multi-driver systems

Speakers Procurement Notes

Verify the specific suffix P143 against official Knowles documentation to confirm terminal configuration and acoustic tuning. Ensure compatibility with existing PCB footprints and housing constraints before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Speakers Selection Notes

Select this component when a rectangular balanced armature driver is required for narrowband or full-range audio tasks in portable devices. Consider the 2.58 mm depth constraint during mechanical design. Evaluate acoustic requirements against the known bandwidth characteristics of the RAB series.

Speakers Part Context

This part belongs to the Knowles RAB (Rectangular Armature Balanced) series, which utilizes balanced armature technology for efficient sound reproduction. The series is widely used in hearing aids, earpieces, and other miniature audio applications where size and fidelity are critical.

Speakers Replacement Considerations

Consult official Knowles substitution guides for compatible alternatives. Verify electrical impedance and sensitivity matches if replacing in an existing circuit. Generic equivalents may not replicate the specific acoustic tuning of the P143 variant.
