EF-26274-000

Speakers Overview

The Knowles EF-26274-000 is a miniature receiver speaker with dimensions of 7.87 x 5.59 x 4.01 mm. It features a side port configuration and operates within a frequency range of 200 Hz to 6.3 kHz. The component has an impedance of 76 Ohms and delivers a sensitivity of 126 dBA.

Speakers Feature Summary

• Compact mechanical design suitable for space-constrained applications
• Side port acoustic configuration for directed sound output
• High efficiency performance with 126 dBA sensitivity

Speakers Applications

• Portable electronic devices requiring small form factor audio output
• Communication equipment utilizing receiver-style speakers
• Consumer electronics needing high-sensitivity acoustic transducers

Speakers Procurement Notes

Verify the specific port orientation (side vs. top) as sources vary between 126 dBA side port and 122 dB top port descriptions. Confirm current availability status as some listings indicate obsolete status. Ensure compatibility with 76 Ohm impedance requirements in the target circuit design before procurement.

Speakers Selection Notes

Select this component when a compact receiver speaker with high sensitivity is required. The 76 Ohm impedance must match the driving circuit capabilities. Consider the physical depth of 4.01 mm for enclosure constraints. Verify if the side port orientation meets the acoustic design needs compared to top-port alternatives.

Speakers Part Context

This part belongs to the Knowles speaker and transducer product line, specifically designed as a miniature receiver unit. It is engineered for applications demanding high acoustic efficiency in a minimal footprint, distinguishing it from larger loudspeaker variants within the manufacturer's portfolio.

Speakers Replacement Considerations

Check for EF-26338-000 as a related alternative. Verify dimensional and impedance compatibility before substitution due to potential differences in port location and sensitivity ratings among similar Knowles receiver models.
