2403 260 00041

Overview

The Knowles 2403 260 00041 is a rectangular receiver speaker designed for surface mounting. It features a nominal impedance of 32 Ohms and a power handling capacity of 40 mW. The device operates within a frequency range of 300 Hz to 10 kHz. Physical dimensions are specified as 10 mm in length, 4.8 mm in width, and 2 mm in height. The unit includes an integrated mesh cover for acoustic protection.

Feature Summary

• Rectangular form factor optimized for compact electronic assemblies
• Integrated protective mesh covering the acoustic port
• Top-ported design configuration for directional sound output

Applications

• Receiver audio circuits in mobile communication devices
• Handset speakers in portable telephony equipment
• Audio output components in compact consumer electronics

Procurement Notes

Verify the specific datasheet version corresponding to the 2403 series before procurement. Confirm that the physical footprint matches the 10 x 4.8 x 2 mm specification required by the design. Ensure the top-port orientation aligns with the enclosure acoustic path. Validate that the 32 Ohm impedance is compatible with the driving circuitry specifications.

Selection Notes

Select this component when a low-profile rectangular receiver is required for handset applications. The 40 mW rating suits standard voice band operations. Consider the 300 Hz lower frequency limit for voice clarity requirements. The 2 mm height constraint makes it suitable for slim device architectures where standard cylindrical speakers cannot fit.

Part Context

This part belongs to the Knowles receiver speaker family, specifically engineered for mobile phone handsets. The 2403 series denotes a standardized rectangular package size widely used in telecommunications hardware. These components serve as primary audio output transducers for incoming call audio in cellular and cordless phones.

Replacement Considerations

Cross-reference with other Knowles 2403 series variants such as 2403 260 00057 for potential mechanical or electrical substitutions. Verify compatibility with existing PCB mounting pads and acoustic venting structures before replacing.
