BK-21613-A27

Overview

The Knowles BK-21613-A27 is a specialized speaker component characterized by a nominal impedance of 160 ohms. It features a side-mounted SS port design, distinguishing its physical configuration from standard center-port variants. This unit is classified under the Speakers & Transducers category and is designed for surface-mount or integrated assembly applications requiring specific acoustic output characteristics within electronic systems.

Feature Summary

• High impedance specification of 160 ohms for specialized audio circuit integration
• Side-mounted SS port architecture for unique acoustic dispersion patterns
• RoHS3 compliant construction ensuring adherence to modern environmental standards

Applications

• Professional audio equipment requiring high-impedance drivers
• Industrial electronic systems with specific acoustic transducer needs
• Custom embedded audio modules utilizing side-port designs

Procurement Notes

Verify RoHS3 compliance status against current regulatory requirements before procurement. Confirm that the 160-ohm impedance matches the target circuit design specifications. Ensure the side-mounted SS port orientation aligns with the mechanical enclosure constraints. Validate manufacturer documentation for any specific handling or mounting instructions associated with this transducer type.

Selection Notes

Select this component only when a 160-ohm impedance is strictly required by the audio amplifier or driver stage. The side-mounted port design necessitates specific mechanical layout considerations compared to traditional center-port speakers. Evaluate whether the acoustic performance benefits of the SS port justify the higher impedance requirement in the final application environment.

Part Context

This part belongs to the Knowles speaker portfolio, specifically engineered for professional and industrial audio applications. Unlike general-purpose consumer speakers, this model emphasizes specific electrical and mechanical attributes such as high impedance and unique porting. It serves niche markets where standard audio components do not meet precise system integration requirements.

Replacement Considerations

Direct substitutes must match the 160-ohm impedance and side-port configuration. Generic speakers with different impedances will alter amplifier loading and frequency response. Verify mechanical dimensions and terminal compatibility before considering alternative models from other manufacturers.
