Overview
The Knowles DFG-30582-000 is a directional cardioid microphone belonging to the FG series. It operates at a supply voltage of 1.3 V with a current rating of 50 uA. The component is packaged in bulk and falls under the audio devices subcategory.
Feature Summary
- Cardioid directional acoustic pattern for focused sound capture
- Low power consumption suitable for portable electronics
Applications
- Voice recognition systems
- Hands-free communication devices
- Portable audio recording equipment
Procurement Notes
Verify the specific datasheet version for the DFG-30582-000 to confirm current RoHS compliance status and any recent manufacturing updates. Ensure that the procurement channel provides authentic Knowles components to avoid counterfeit parts. Check for any specific handling requirements during storage and assembly.
Selection Notes
Select this model when a cardioid polar response is required to reject off-axis noise. Compare against the unidirectional DFG-30581-000 if omnidirectional pickup is preferred. Confirm that the 1.3 V operating voltage aligns with the target system's power budget and interface circuitry.
Part Context
This microphone is part of the Knowles FG series, which focuses on compact audio solutions. The manufacturer specializes in high-performance audio devices for consumer electronics. The FG series typically integrates MEMS technology for reliable performance in small form factors.
Replacement Considerations
The DFG-30581-000 is a related variant within the same series but features a unidirectional pattern instead of cardioid. Verify acoustic requirements before substitution.
