Overview
The TM-27830-C36 is an omnidirectional electret microphone manufactured by Knowles. It features a sensitivity of -39.5 dBA and operates at a supply voltage of 1.3 VDC with a current rating of 50 uA. The component has an impedance of 3.5 kOhms and is designed for operation at a frequency of 10 kHz. Its physical dimensions are 5.56 mm in length, 3.98 mm in width, and 2.21 mm in depth. The device utilizes screw termination style.
Feature Summary
- Omnidirectional acoustic pickup pattern
- Low power consumption design
- Compact surface-mount form factor
Applications
- Portable audio recording devices
- Voice recognition systems
- Consumer electronics audio input
Procurement Notes
Verify the specific sensitivity variant, as sources indicate -39.5 dBA, while other similar models may differ. Confirm the termination style matches the target PCB layout. Ensure the operating voltage aligns with the system's power supply constraints. Check for RoHS compliance status if required by regional regulations. Validate the package dimensions against mechanical clearance requirements.
Selection Notes
Select this component when an omnidirectional response is required for general sound capture. The low operating current makes it suitable for battery-powered applications. The compact size allows integration into space-constrained enclosures. Verify that the impedance matches the preamplifier input stage. Consider the sensitivity level relative to the expected sound pressure levels in the application environment.
Part Context
This microphone belongs to Knowles' portfolio of electret condenser microphones. These components are widely used in consumer electronics due to their reliability and consistent performance. The series offers various sensitivity options and package sizes to suit different design needs. Knowles manufactures these devices using established processes to ensure quality and longevity.
Replacement Considerations
Direct substitutes include other omnidirectional microphones from Knowles with similar electrical characteristics. Models like EA-21867-C36 share dimensional similarities but differ in sensitivity. Verify pinout compatibility before substitution. Cross-reference datasheets for impedance and voltage requirements.
