FC-26170-000

Speakers Overview

The Knowles FC-26170-000 is a balanced armature receiver designed for audio applications. It operates within a frequency range of 200 Hz to 5.8 kHz and features an impedance of 845 Ohms. The device achieves a sound pressure level of 104 dBA under constant voltage drive conditions, with a sensitivity peak of 5 dB relative to the standard at 1 kHz. Physical dimensions include a length of 5.18 mm and a height of 3.05 mm. The technology utilizes ferrofluid damping and Type 111 damping mechanisms to ensure performance stability.

Speakers Feature Summary

• Balanced armature transducer technology
• Ferrofluid and Type 111 damping integration
• Rectangular form factor design

Speakers Applications

• Audio receivers in portable electronic devices
• Communication equipment requiring high efficiency
• Consumer electronics with space-constrained layouts

Speakers Procurement Notes

Verify the specific revision or suffix against official Knowles documentation before procurement, as manufacturing updates may occur. Confirm that the 845 Ohm impedance specification aligns with your circuit design requirements. Ensure compatibility with existing assembly processes given the rectangular package dimensions. Check for any recent obsolescence notices or lifecycle status changes directly from the manufacturer.

Speakers Selection Notes

Select this component when a high-efficiency receiver with a specific impedance profile is required. The 104 dBA output provides strong acoustic performance for its size. Consider the 200 Hz to 5.8 kHz bandwidth to ensure it meets the target audio frequency response needs. The balanced armature architecture offers advantages in power consumption and linearity compared to dynamic alternatives.

Speakers Part Context

This model belongs to the Knowles FC series of balanced armature receivers. These components are widely used in hearing aids, mobile phones, and other compact audio devices where small size and high reliability are critical. The series typically employs proprietary damping technologies to enhance acoustic consistency and durability across various operating environments.

Speakers Replacement Considerations

FC-30001-000 is listed as an obsolete direct substitute option in some distributor catalogs, though availability should be verified. Ensure any replacement maintains the 845 Ohm impedance and similar dimensional constraints to fit existing footprints without mechanical modification.
