Overview
The Coilcraft CDF8000LD is a surface-mount common mode choke designed for data line EMI filtering. It features a ferrite core and offers an inductance of 5 µH with a DC resistance maximum of 0.25 ohms. The component supports a DC current rating of 100 mA and provides an impedance of 630 ohms at 37 MHz. Its compact package dimensions are 8 mm in length, 8 mm in width, and 4.5 mm in height.
Feature Summary
- Designed specifically for suppressing electromagnetic interference on data lines
- Utilizes a ferrite core material for effective common mode noise attenuation
- Constructed for reliable surface mount PCB integration
Applications
- Data line signal integrity protection
- Common mode noise suppression in electronic circuits
- EMI filtering for high-speed digital interfaces
Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and specifications. Confirm that the required inductance, current rating, and impedance values align with the specific design requirements. Check datasheet details for mounting orientation and soldering profiles to guarantee proper assembly and long-term reliability in the target application.
Selection Notes
Select this component when a low-profile solution is needed for data line filtering. Ensure the 100 mA current rating meets the operational load without saturation. Verify that the 630 ohm impedance at 37 MHz provides sufficient attenuation for the targeted noise frequencies. Consider the physical footprint constraints against the 8x8x4.5 mm dimensions during layout planning.
Part Context
This component belongs to the CDF series of data line EMI filters manufactured by Coilcraft. These components are engineered to provide compact noise suppression solutions for sensitive electronic signals. The series focuses on maintaining signal integrity while minimizing electromagnetic interference in space-constrained designs.
Replacement Considerations
Consult official Coilcraft documentation for verified cross-reference part numbers. Do not substitute with generic components unless electrical parameters such as inductance, current rating, and impedance are identical. Verify package compatibility before replacing.
