EF-26872-000

Speakers Overview

The Knowles EF-26872-000 is a rectangular general-purpose speaker with an impedance of 636 Ohms. It operates within a frequency range of 200 Hz to 6.3 kHz and features solder pad termination. The physical dimensions are 7.87 x 5.59 x 4.01 mm, with a sensitivity of 118 dB and a single port configuration.

Speakers Feature Summary

• Rectangular form factor designed for compact integration
• Solder pad termination for direct board mounting
• General-purpose audio output capability

Speakers Applications

• Consumer electronics audio output
• Industrial equipment signaling
• Medical device acoustic alerts

Speakers Procurement Notes

Verify the specific impedance value of 636 Ohms against circuit requirements, as this is a non-standard value compared to common 8 or 16 Ohm speakers. Confirm that the rectangular package dimensions fit the designated enclosure space. Ensure the solder pad termination method aligns with the assembly process capabilities. Check RoHS compliance status if required by regulatory standards.

Speakers Selection Notes

Select this component when a high-sensitivity, low-profile rectangular speaker is needed for general audio applications. The 636 Ohm impedance suggests it may be intended for specific driver circuits or voltage-driven applications rather than standard low-impedance amplifiers. Consider the 200 Hz to 6.3 kHz frequency response for voice or alert tones rather than full-range music reproduction.

Speakers Part Context

This part belongs to the Knowles Speakers & Transducers product line. It is categorized under general-purpose speakers suitable for various electronic devices requiring audible feedback. The manufacturer provides datasheets detailing the electrical and mechanical specifications for design integration.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Replacement requires matching the 636 Ohm impedance, rectangular form factor, and dimensional constraints.
