Overview
The Würth Elektronik 748020024 is a Surface Mount Technology (SMT) ceramic common mode filter belonging to the WE-CCMF series. It features a compact multilayer construction designed for high-speed differential signal lines. Key electrical parameters include an inductance of 245 pH, a maximum DC resistance of 2.5 ohms, and a current rating of 300 mA. The component operates within a temperature range up to 125°C and complies with SVHC regulations.
Feature Summary
- Compact multilayer ceramic construction suitable for space-constrained designs
- Engineered specifically for high-speed differential signal applications
- Surface mount technology facilitates automated PCB assembly
Applications
- High-speed differential data lines
- General electronic equipment signal filtering
- Common mode noise suppression in compact modules
Procurement Notes
Verify the specific package dimensions and termination compatibility against your PCB footprint before ordering. Confirm that the 300 mA current rating meets your circuit's operational requirements. Ensure the design supports SMT assembly processes compatible with this component type. Check for any specific handling instructions regarding the ceramic material.
Selection Notes
Select this component when space is limited and high-speed signal integrity is critical. The low inductance value suits applications requiring minimal signal delay. Consider the 2.5 ohm DC resistance impact on voltage drop. Evaluate if the ceramic construction offers sufficient thermal stability for your environment compared to other filter types.
Part Context
This part belongs to the WE-CCMF series from Würth Elektronik, which specializes in SMT ceramic common mode filters. These components are distinct from wirewound chokes due to their planar structure and suitability for dense layouts. The series targets modern electronics where miniaturization and high-frequency performance are mandatory constraints.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and impedance characteristics carefully if considering alternative manufacturers.
