2403 260 00091

Overview

The Knowles 2403 260 00091 is a general-purpose rectangular speaker designed for top port applications. It features a nominal impedance of 6 Ohms and supports a maximum power handling capacity of 700 mW. The device operates within a frequency range of 300 Hz to 20 kHz, providing standard audio reproduction capabilities. The physical profile includes a seated height of 0.138 inches (3.50 mm), facilitating integration into compact electronic assemblies where space constraints are critical.

Feature Summary

• Rectangular form factor optimized for top port acoustic output
• General-purpose design suitable for broad audio signal transmission
• Compact seated height enabling integration in space-constrained enclosures

Applications

• Consumer electronics requiring compact audio output
• Industrial control panels with limited internal volume
• Portable devices needing general-purpose sound reproduction

Procurement Notes

Verify the specific datasheet version provided by Knowles Electronics to confirm mechanical dimensions and electrical tolerances prior to integration. Ensure that the mounting configuration aligns with the target enclosure design. Cross-reference the part number format to distinguish between variations in acoustic tuning or impedance if multiple similar SKUs exist within the Cobra series.

Selection Notes

Select this component when a low-profile rectangular speaker is required for general audio tasks. The 6 Ohm impedance matches common amplifier outputs, while the 700 mW rating ensures adequate power handling for typical consumer applications. Consider the 300 Hz lower frequency limit when designing for bass-heavy requirements, as this unit is not optimized for deep low-frequency response.

Part Context

This model belongs to the Knowles Cobra speaker series, which focuses on compact, high-performance transducers. The 2403 series typically utilizes specific magnetic structures and diaphragm materials to achieve reliable performance in small form factors. This particular variant emphasizes general utility over specialized acoustic tuning.

Replacement Considerations

Direct substitutes may include other rectangular speakers from the same manufacturer with matching 6 Ohm impedance and similar physical dimensions. Verify acoustic center alignment and mounting hole patterns when considering alternative models from different manufacturers.
