EF-26426-000

Speakers Overview

The Knowles EF-26426-000 is a rectangular receiver speaker with an impedance of 160 Ohms. It features a side port design and delivers a sensitivity of 123.5 dB. The frequency range spans from 200 Hz to 6.3 kHz. Physical dimensions are 7.87 mm in length, 5.59 mm in width, and 4.01 mm in height. Termination is via solder pads.

Speakers Feature Summary

• Rectangular form factor optimized for compact assemblies
• Side port configuration for acoustic directionality
• High sensitivity output for efficient signal conversion

Speakers Applications

• Portable electronic devices requiring small form factors
• Medical equipment audio interfaces
• Industrial control panel indicators

Speakers Procurement Notes

Verify the specific impedance value of 160 Ohms against circuit requirements, as this differs from standard 8 or 32 Ohm speakers. Confirm the side port orientation matches the enclosure design for proper sound projection. Ensure solder pad compatibility with the manufacturing process. Check RoHS compliance status if required by project specifications.

Speakers Selection Notes

Select this component when high sensitivity is prioritized over low-frequency response due to its limited lower frequency cutoff at 200 Hz. The 160 Ohm impedance requires compatible driver circuits designed for higher resistance loads. Consider the physical constraints of the 7.87 x 5.59 mm footprint during mechanical design.

Speakers Part Context

This part belongs to the Knowles speaker and transducer family, specifically within the receiver category. It is designed for applications where space is limited but clear audio output is necessary. The product line emphasizes miniaturization while maintaining acoustic performance standards for consumer and industrial electronics.

Speakers Replacement Considerations

Direct substitutes must match the 160 Ohm impedance and similar dimensional constraints. Verify that alternative receivers support the same frequency range up to 6.3 kHz. Ensure termination type remains compatible with existing PCB layouts.
