Procurement Notes
Verify the specific suffix codes against official Knowles documentation to ensure correct impedance and connector compatibility. Confirm that the procurement channel provides genuine components with traceable manufacturing dates. Request detailed datasheets for the exact part number variant to validate electrical specifications before integration into final designs.
Selection Notes
Select this model when omnidirectional pickup is required for voice-centric applications. Ensure the host circuitry supports the capacitive load of an electret capsule. Verify that the physical dimensions align with the intended enclosure constraints. Consider the operating voltage requirements of the integrated preamplifier within the capsule assembly during system power budgeting.
Part Context
This component belongs to the Knowles 8200 series of miniature microphone capsules. The series is engineered for high-fidelity audio applications in professional and industrial sectors. These capsules are known for their consistency in mass production and reliability in harsh conditions, serving as core transducers in various acoustic sensing solutions.
Replacement Considerations
Consult official Knowles substitution guides for direct equivalents. Verify pinout compatibility and electrical parameters such as capacitance and bias voltage before swapping with alternative brands. Physical mounting hole patterns must match exactly to avoid mechanical modification.
