FK-26768-000

Speakers Overview

The Knowles FK-26768-000 is a balanced armature speaker transducer designed for high-fidelity audio applications. It features a rectangular shape and operates within a frequency range of 200 Hz to 6.9 kHz. The component exhibits an impedance of 1.03 kOhms and an efficiency of 98.00 dB SPL. Its physical dimensions are specified as 5 mm in length, with a top-mount configuration suitable for space-constrained environments.

Speakers Feature Summary

• Balanced armature driver technology for precise sound reproduction
• Rectangular form factor optimized for compact device integration
• High efficiency performance for clear audio output

Speakers Applications

• Space-constrained hearing aids
• In-ear monitors
• Compact audio receivers

Speakers Procurement Notes

Verify the specific revision status and RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Confirm that the rectangular package dimensions align with your PCB layout constraints. Ensure the operating temperature range meets your environmental requirements. Check for any recent product change notifications regarding material or process updates.

Speakers Selection Notes

Select this component when a balanced armature architecture is required for high-frequency clarity in small enclosures. The 1.03 kOhm impedance suggests compatibility with specific driver amplifiers. Consider the 200 Hz lower frequency limit when designing acoustic chambers. Evaluate the 98.00 dB efficiency against power consumption targets.

Speakers Part Context

This part belongs to the Knowles Speakers & Transducers category, specifically utilizing balanced armature technology. It is distinct from dynamic drivers and other microphone products in the Knowles portfolio. The rectangular design differentiates it from circular balanced armature units.

Speakers Replacement Considerations

Cross-reference with other Knowles balanced armature speakers such as those in the CI or ED series for similar dimensional and electrical characteristics. Verify impedance matching and frequency response overlap before substitution.
