2403 260 00177

Overview

The Knowles 2403 260 00177 is a Wildcat S9 WP speaker designed for audio applications. It features an 8-ohm impedance and a top port location. The device operates within a frequency range of 300 Hz to 20 kHz. It has a sensitivity of 97 dB and can handle a maximum power of 700 mW. The physical dimensions are 11 mm in width, 15 mm in length, and 3.5 mm in height.

Feature Summary

• Top port configuration for directed sound output
• Wildcat S9 WP series construction for durability
• Compact rectangular form factor suitable for space-constrained designs

Applications

• Portable audio devices requiring compact speakers
• Consumer electronics with limited internal volume
• Industrial audio signaling units

Procurement Notes

Verify the specific suffix against the manufacturer's current documentation to ensure compatibility with required acoustic performance standards. Confirm that the top port orientation aligns with the mechanical enclosure design. Check for any updated RoHS or REACH compliance statements relevant to the target market regulations before finalizing procurement orders.

Selection Notes

Select this component when a small footprint is critical alongside moderate power handling requirements. The 8-ohm impedance matches standard amplifier outputs commonly found in portable systems. Ensure the application environment does not exceed the thermal limits implied by the 700 mW rating. Consider the 97 dB sensitivity for efficiency in battery-powered designs.

Part Context

This part belongs to the Knowles Wildcat S9 WP series, which focuses on high-performance audio solutions in miniature packages. The series is engineered for reliability in consumer and industrial sectors. The 2403 designation indicates the specific size code within the broader product family.

Replacement Considerations

Direct substitutes must match the 11x15x3.5 mm dimensions and 8-ohm impedance. Verify that alternative models maintain the 300 Hz to 20 kHz frequency response. Ensure the replacement also utilizes a top port configuration to fit existing acoustic chambers without redesign.
