Overview
The Knowles TM-26898-C36 is a subminiature omnidirectional electret condenser microphone designed for high-performance audio capture in space-constrained environments. It features a compact physical footprint suitable for rugged applications. The device operates with an analog output type and utilizes a pad termination style for surface mounting. Key electrical characteristics include a sensitivity of -54 dBA and an impedance of 3.5 kOhms. It functions within a frequency range of 10 kHz and requires an operating supply voltage of 1.3 VDC with a current rating of 50 uA.
Feature Summary
- Subminiature form factor optimized for space-constrained designs
- Omnidirectional acoustic response for uniform sound pickup
- Electret condenser technology for reliable analog audio capture
Applications
- Portable electronic devices requiring compact audio input
- Rugged environmental audio recording systems
- Consumer electronics with limited internal volume
Procurement Notes
Verify the specific datasheet version to confirm mechanical dimensions and electrical tolerances against your design requirements. Ensure compatibility with the intended PCB layout for pad termination. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with official manufacturer documentation to avoid counterfeit components.
Selection Notes
Select this component when a small, omnidirectional microphone is needed for low-power analog audio applications. Consider the 1.3 VDC operating voltage and 50 uA current consumption for power budget calculations. Evaluate the 3.5 kOhm impedance against your preamplifier input requirements. Ensure the physical size fits within the available enclosure space.
Part Context
This component belongs to the Knowles TM Series, which focuses on combining performance with minimal size. The series targets applications where traditional microphones are too large. The TM-26898-C36 specifically addresses the need for robust audio sensing in compact consumer and industrial devices.
Replacement Considerations
Check for direct substitutes within the Knowles TM series that share identical pinouts and acoustic characteristics. Verify that any alternative maintains the same omnidirectional pattern and sensitivity levels. Ensure mechanical compatibility with existing PCB footprints.
