Overview
The Delevan CM6149-105 is a surface-mount common mode filter choke designed for PCB integration. It features an inductance of 1 mH measured at 10 kHz with a tolerance of 25%. The component supports a maximum DC current of 1 A and exhibits a maximum DC resistance of 250 mOhms. Its physical dimensions are 7.24 mm in length, 7.24 mm in width, and a maximum height of 5.33 mm. The device operates within a temperature range of -55°C to +105°C.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Utilizes a low-profile surface mount package for space-constrained designs
- Constructed as an unshielded component for standard electromagnetic compatibility applications
Applications
- Signal line filtering in electronic circuits
- Noise reduction in data transmission interfaces
- Electromagnetic interference suppression in compact devices
Procurement Notes
Verify the specific suffix or packaging designation when ordering, as availability may vary between bulk and reel formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to final procurement decisions. Ensure the selected variant matches the required inductance and current ratings for the target application circuit.
Selection Notes
Select this component when a 1 mH inductance value is required for common mode noise attenuation. The 1 A current rating suits moderate power signal lines. The 7.24 x 7.24 mm footprint must be accommodated on the PCB layout. Verify that the unshielded construction meets the system's electromagnetic interference requirements.
Part Context
This part belongs to the CM6149 series of common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering needs. The CM6149-105 specifically provides higher inductance compared to lower-value variants in the same family, suitable for stricter noise suppression requirements.
Replacement Considerations
Cross-reference with other CM6149 series variants such as CM6149-104 or CM6149R-105 if different inductance or packaging options are needed. Ensure any substitute maintains compatible current handling and physical footprint constraints.
