Overview
The CMEJ-4618-38-L060 is an omnidirectional electret condenser microphone manufactured by Same Sky. It features a cylindrical metal housing with a diameter of 4.6 mm and a depth of 1.8 mm. The device operates at a supply voltage of 2.0 VDC with a current rating of 500 uA. It provides a sensitivity of -38 dB and has an impedance of 2.2 kOhms. Frequency response ranges from 100 Hz to 10 kHz. Termination is achieved via wire leads, specifically 60 mm in length.
Feature Summary
- Omnidirectional acoustic pattern for uniform sound capture
- Electret condenser technology for analog audio signal conversion
- Compact cylindrical metal housing design
- Wire lead termination for flexible integration
Applications
- Consumer electronic devices requiring compact audio input
- Voice recording equipment
- Intercom systems
- Telecommunication handsets
Procurement Notes
Verify the specific suffix 'L060' confirms the 60 mm wire length specification. Confirm RoHS compliance status through official manufacturer documentation or certificates. Ensure the operating voltage requirements align with the 2.0 VDC specification before procurement.
Selection Notes
Select this component when an omnidirectional pickup pattern is required within strict spatial constraints due to its small 4.6 mm diameter. Consider the fixed 60 mm wire length for routing flexibility. Evaluate the -38 dB sensitivity against ambient noise levels in the target application environment.
Part Context
This microphone belongs to the CMEJ-4618 series, which shares common physical dimensions and electrical characteristics. Variations within the series typically involve differences in sensitivity ratings, such as -42 dB models, or wire length specifications. All variants maintain the same 4.6 mm form factor and 2.0 VDC operating voltage.
Replacement Considerations
Compatible substitutes include other CMEJ-4618 series variants like CMEJ-4618-38-L046 or CMEJ-4618-42-LX, provided the wire length and sensitivity meet system requirements. Cross-reference pinout and mounting orientation to ensure mechanical compatibility.
