EF-26329-000

Speakers Overview

The Knowles EF-26329-000 is a rectangular electromagnetic speaker transducer designed for audio signal reproduction. It features a nominal impedance of 150 Ohms and a sensitivity level of 126 dBA. The device operates within a frequency range of 200 Hz to 6.3 kHz. Its physical dimensions are 7.87 mm in length, 5.59 mm in width, and 4.01 mm in height. The unit utilizes a side port configuration and employs solder pad termination styles for surface mount integration.

Speakers Feature Summary

• Rectangular form factor with side port acoustic design
• High sensitivity output of 126 dBA for efficient sound projection
• Surface mount solder pad termination for PCB integration

Speakers Applications

• Audio signaling devices
• Electronic alert systems
• Compact consumer electronics

Speakers Procurement Notes

Verify the specific datasheet revision to confirm mechanical tolerances and acoustic performance curves. Ensure the procurement documentation explicitly states the side port orientation, as this affects acoustic coupling in the final assembly. Confirm that the solder pad termination style matches the target PCB footprint design requirements before placing orders.

Speakers Selection Notes

Select this component when a high-sensitivity, low-profile rectangular speaker is required for space-constrained designs. The 150 Ohm impedance and 200 Hz to 6.3 kHz frequency response define its suitability for specific audio bands. Evaluate the 4.01 mm height constraint against available vertical clearance in the enclosure design.

Speakers Part Context

This model belongs to the Knowles EF series of speakers and transducers. The series provides various electromagnetic solutions for audio applications. The EF-26329-000 specifically addresses needs for compact, high-output sound generation in electronic assemblies requiring precise dimensional control.

Speakers Replacement Considerations

Cross-reference with other Knowles EF series models for similar impedance and sensitivity. Verify that any substitute maintains the 7.87 x 5.59 mm footprint and side port configuration to ensure mechanical compatibility.
