Overview
The Knowles TM-23568-C56 is an omnidirectional electret microphone designed for audio signal capture. It features a sensitivity of -56 dBA and an impedance of 4.4 kOhms. The component has a compact length of 3.57 mm, suitable for space-constrained electronic assemblies.
Feature Summary
- Omnidirectional acoustic response for uniform sound pickup from all directions
- Integrated electret capsule structure for direct signal conversion
- Compact physical dimensions facilitating integration into small form-factor devices
Applications
- Consumer audio recording devices
- Voice recognition systems
- Telecommunication handsets
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status, as conflicting information exists regarding regulatory adherence. Ensure the supplier provides official Knowles documentation to validate the part number authenticity and electrical specifications before procurement.
Selection Notes
Select this component when an omnidirectional polar pattern is required for ambient sound capture. The fixed impedance and sensitivity values dictate preamplifier matching requirements. Verify mechanical fit against the 3.57 mm length constraint during PCB layout design.
Part Context
This model belongs to the Knowles electret microphone product line, which focuses on miniaturized audio transducers. These components are engineered for consistent performance in portable electronics, offering reliable acoustic-to-electrical conversion within standard industrial temperature ranges.
Replacement Considerations
No publicly confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching impedance, sensitivity, and mechanical footprint specifications with alternative manufacturers.
