CB-23817-000

Overview

The Knowles CB-23817-000 is a balanced armature receiver speaker designed for audio applications. It features a magnetic technology with an impedance of 48 Ohms and a sensitivity of 80 dBA. The device operates within a frequency range of 700 Hz to 4 kHz and utilizes a top port configuration.

Feature Summary

• Balanced armature receiver technology
• Top port acoustic design
• Magnetic actuation mechanism

Applications

• Audio receivers
• Communication devices
• Portable electronics

Procurement Notes

Verify the specific datasheet version and manufacturing origin when sourcing this component. Confirm that the 48 Ohm impedance and 80 dBA sensitivity specifications match your circuit requirements. Ensure compatibility with the intended acoustic housing due to the top port design. Check for any RoHS compliance status updates from the manufacturer prior to final procurement decisions.

Selection Notes

Select this component for designs requiring a compact balanced armature solution with defined mid-to-high frequency response. The 48 Ohm impedance suits specific driver circuits, while the 80 dBA efficiency provides adequate output for standard receiver roles. Evaluate the 700 Hz to 4 kHz bandwidth against target voice or audio clarity needs.

Part Context

This part belongs to the Knowles CB series of speakers. It is categorized as a balanced armature transducer manufactured by Knowles. The component is distinct from ceramic capacitors also produced by the manufacturer, serving specifically as an electro-acoustic output device rather than a passive electronic filter element.

Replacement Considerations

Consult official Knowles documentation for direct cross-references. Verify mechanical footprint and electrical parameters before substituting with other balanced armature receivers.
