Overview
The Würth Elektronik 748030024 is a Surface Mount Technology (SMT) ceramic common mode filter belonging to the WE-CCMF series. It features a compact footprint of 1.25 x 1 x 0.8 mm. The component provides a minimum common mode attenuation of 30 dB at 2450 MHz. It has a DC current rating of 300 mA and a maximum DC resistance of 2.5 ohms. The inductance value is specified as 0.245 nH.
Feature Summary
- Utilizes SMT ceramic construction for high-frequency signal integrity
- Provides significant common mode noise attenuation at 2450 MHz
- Designed for general electronic equipment applications
Applications
- General electronic equipment
- High-frequency signal line filtering
- Common mode noise suppression in compact circuits
Procurement Notes
Verify the specific package dimensions and electrical tolerances against the official datasheet before integration. Confirm that the 300 mA current rating meets the operational requirements of the target circuit. Ensure compatibility with standard SMT reflow processes. Check for RoHS compliance documentation if required by the end product regulations.
Selection Notes
Select this component when space constraints require a small form factor such as 1.25 x 1 mm. It is suitable for applications needing effective attenuation at 2450 MHz. Consider the 2.5 ohm DC resistance impact on signal loss. Evaluate the 300 mA limit against peak current demands to prevent saturation or overheating.
Part Context
This part belongs to the WE-CCMF series, which consists of surface mount ceramic common mode filters manufactured by Würth Elektronik. These components are engineered for general electronic equipment where size and performance are critical. The series offers various inductance values and current ratings to suit different filtering needs.
Replacement Considerations
Consult the manufacturer's datasheet for direct cross-reference information. Verify pinout compatibility and physical dimensions before substituting with other common mode filters. Ensure equivalent attenuation characteristics at the target frequency.
