2403 260 00031

Overview

The Knowles 2403 260 00031 is a dynamic receiver speaker designed for space-constrained audio applications. It features a rectangular form factor with a top port configuration, measuring 12 mm in length and 2 mm in height. The component operates at an impedance of 32 Ohms and handles a maximum power rating of 40 mW. Its frequency response spans from 100 Hz to 10 kHz, ensuring effective sound reproduction within this band. The unit utilizes magnetic technology and is packaged in tape and reel format for automated surface-mount assembly.

Feature Summary

• Rectangular design optimized for high space efficiency in compact devices
• Top port acoustic configuration for directed sound output
• Dynamic magnetic technology for reliable audio transduction

Applications

• Mobile communication handsets
• Portable electronic devices requiring small form factors
• Embedded audio systems with limited internal volume

Procurement Notes

Verify the specific revision status as this part may be listed as obsolete in certain distributor catalogs. Confirm mechanical dimensions against current PCB footprint requirements, specifically the 12 mm length and 2 mm height constraints. Ensure compatibility with automated pick-and-place equipment given the tape and reel packaging method. Cross-reference datasheet revisions to confirm terminal plating and acoustic performance specifications match the target application needs.

Selection Notes

Select this component when strict spatial limitations dictate the use of a rectangular receiver with a top port. The 32 Ohm impedance aligns with standard audio amplifier outputs, while the 40 mW power handling suits low-to-moderate volume requirements. Consider the 100 Hz to 10 kHz frequency range suitability for voice-centric applications rather than full-range music playback. Evaluate board flexure resistance if the device undergoes mechanical stress during operation.

Part Context

This model belongs to the Knowles dynamic receivers series, engineered for integration into portable electronics. These components prioritize miniaturization without compromising acoustic integrity. The product line typically serves industries demanding reliable audio solutions in tight enclosures, such as telecommunications and wearable technology sectors.

Replacement Considerations

Check manufacturer archives for direct successor models or updated versions of the 2403 series. Verify that any substitute maintains the identical 12x2 mm envelope and top-port orientation to ensure mechanical fit. Confirm electrical equivalence regarding the 32 Ohm impedance and 40 mW power rating before finalizing any substitution plan.
