2403 263 00092

Overview

The Knowles 2403 263 00092 is a rectangular receiver speaker with an impedance of 32 Ohms and a power handling capacity of 100 mW. It features a top port design and operates within a frequency range of 160 Hz to 10 kHz. The physical dimensions are 15.00 mm in length and 8.00 mm in width, with a height of 1.5 mm. The device achieves a sound pressure level of 25.5 dB.

Feature Summary

• Rectangular form factor designed for compact integration
• Top port acoustic configuration for directed sound output
• High sensitivity performance relative to input power

Applications

• Receiver audio modules in communication devices
• Compact consumer electronics requiring small form factors
• Industrial control panels with limited space constraints

Procurement Notes

Verify the specific acoustic requirements against the 25.5 dB SPL rating and 32 Ohm impedance before procurement. Confirm that the 100 mW power handling aligns with the target application's signal levels. Ensure the 15x8x1.5 mm physical dimensions fit the designated enclosure space. Check for any specific mounting or porting requirements associated with the top port design.

Selection Notes

Select this component when a small rectangular speaker is required for receiver applications. The 32 Ohm impedance suits standard low-voltage driver circuits. Consider the 160 Hz lower frequency limit if bass response is critical. The top port orientation must be compatible with the device's acoustic path. Evaluate the 100 mW power rating against maximum expected audio signals to prevent damage.
