2403 260 00071

Overview

The Knowles 2403 260 00071 is a general-purpose speaker from the Grand series, designed for space-constrained consumer devices. It features an 8-ohm impedance and a frequency response range of 300 Hz to 20 kHz. The unit delivers a sound pressure level of 73 dB with a maximum power handling capacity of 600 mW. Its physical dimensions are 13 mm by 18 mm by 2.5 mm, providing high space efficiency. The top port location facilitates direct sound projection in slim enclosures.

Feature Summary

• Extremely slim profile with a height of only 2.5 mm for integration into thin devices
• Top port configuration for optimized acoustic output direction
• High space efficiency within a compact 13x18 mm footprint

Applications

• Small consumer electronic devices requiring minimal depth
• Slim portable audio equipment
• Compact home entertainment systems

Procurement Notes

Verify the specific part number against official Knowles documentation to ensure compatibility with design requirements. Confirm that the 2.5 mm height constraint aligns with the target enclosure specifications. Check for any RoHS compliance status updates if environmental regulations apply to the final product assembly. Ensure the 8-ohm impedance matches the amplifier output capabilities.

Selection Notes

Select this component when vertical space is limited to 2.5 mm. The 8-ohm impedance suits standard low-voltage audio drivers. The 300 Hz to 20 kHz range covers typical voice and mid-to-high frequency audio needs. Consider the 73 dB sensitivity for required volume levels in the intended application environment.

Part Context

This speaker belongs to the Grand series, which focuses on maximizing audio performance within minimal physical envelopes. The series targets manufacturers prioritizing form factor reduction without significant acoustic compromise. The 2403 260 00071 variant specifically utilizes a rectangular package shape suitable for surface mounting or adhesive attachment in tight spaces.
