Overview
The Knowles BK-21610-028 is a compact electrostatic receiver designed for audio signal reproduction in portable electronic devices. It features a nominal impedance of 21 ohms and utilizes a stainless steel port located on the end of the housing to facilitate sound output. The component is constructed with surface-mount technology, allowing for automated assembly onto printed circuit boards. This receiver is engineered to deliver clear audio performance within space-constrained environments typical of modern consumer electronics.
Feature Summary
- Integrated stainless steel acoustic port positioned at the device end
- Surface-mount construction for efficient PCB integration
- Optimized acoustic design for compact audio applications
Applications
- Portable communication devices
- Mobile handsets
- Wearable audio equipment
Procurement Notes
Verify the specific part number BK-21610-028 against official Knowles documentation to confirm the 21-ohm impedance specification and stainless steel port configuration. Ensure that the selected component matches the required acoustic performance characteristics for the intended application. Cross-reference datasheets to validate mechanical dimensions and mounting requirements before procurement.
Selection Notes
Select this component when a low-profile, surface-mount receiver with a defined 21-ohm impedance is required. The end-port design influences acoustic orientation and must be considered during mechanical layout. Evaluate the physical constraints of the enclosure to ensure compatibility with the component's footprint and height specifications.
Part Context
This model belongs to the Knowles speaker and transducer product line, specifically categorized as an electrostatic receiver. These components are widely utilized in the telecommunications and consumer electronics sectors where reliable audio output is critical. The series emphasizes miniaturization and robust performance in small form factors.
Replacement Considerations
Consult official Knowles documentation for verified substitute part numbers. Do not assume interchangeability based solely on impedance or package type without confirming acoustic and mechanical specifications.
