FC-26887-000

Speakers Overview

The Knowles FC-26887-000 is a balanced armature receiver designed for surface mount applications. It features a rectangular shape with top porting configuration. The component operates within a frequency range of 200 Hz to 5.2 kHz and delivers a sound pressure level efficiency of 100 dB. It has an electrical impedance of 550 Ohms. Physical dimensions include a height of approximately 3.05 mm, width of 3.55 mm, and length of 5.18 mm. The device is RoHS compliant and manufactured by Knowles.

Speakers Feature Summary

• Balanced armature transducer technology for high-fidelity audio reproduction
• Top port design optimized for specific acoustic enclosure integration
• High sensitivity output providing efficient sound generation at low drive levels
• Rectangular form factor suitable for compact electronic device layouts

Speakers Applications

• Hearing aids requiring high fidelity audio output
• Wireless earbuds and in-ear monitors
• Smartphones and mobile communication devices
• Voice recognition modules and smart speakers

Speakers Procurement Notes

Verify the specific port configuration (top vs side) against your mechanical design requirements, as Knowles offers variants like FC-30001-000 with side ports. Confirm impedance matching with your driver circuitry to ensure optimal power transfer and signal integrity. Ensure the PCB footprint matches the precise dimensional tolerances of the 5.18 x 3.55 mm package. Check for RoHS compliance documentation if operating in regulated markets.

Speakers Selection Notes

Select this component when high sensitivity and wide bandwidth are critical for voice or music reproduction in space-constrained environments. The 550 Ohm impedance requires consideration for amplifier compatibility compared to lower impedance alternatives. Evaluate the top port orientation against available acoustic chambers in the final assembly. Compare against similar Knowles models like FC-26755-000 if different impedance characteristics are needed.

Speakers Part Context

This part belongs to Knowles' portfolio of precision audio receivers. Balanced armature technology is standard in miniaturized audio applications due to its efficiency and size advantages over dynamic drivers. The FC series represents established designs used across consumer electronics and medical devices. Knowles maintains strict quality controls for these components to ensure consistent acoustic performance.

Speakers Replacement Considerations

Direct substitutes may include other Knowles balanced armature receivers such as the FC-30001-000, though it features a side port instead of top porting. Verify that any replacement maintains the 550 Ohm impedance and 100 dB SPL efficiency to prevent acoustic mismatch. Cross-reference physical dimensions to ensure fit within the existing PCB layout and housing constraints.
