- High-speed data line filtering
Procurement Notes
Verify the specific manufacturer datasheet for the latest electrical tolerances and thermal characteristics. Confirm that the 7345 footprint matches your PCB layout constraints. Ensure the selected component variant aligns with your required operating temperature range and current ratings for the final assembly.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for high-speed signals. The 100 µH inductance offers effective filtering at lower frequencies, while the 50 kΩ impedance targets higher frequency interference. Consider the 350 mA current rating to ensure adequate headroom for the application's peak operational demands without saturation.
Part Context
This part belongs to the WE-SCC series of Stromkompensierter SMD Line Filters. These components are engineered specifically for automotive electronics applications where robust noise immunity and compact form factors are critical. The series utilizes ferrite core technology to achieve high impedance values within a small surface-mount package.
Replacement Considerations
Cross-reference with other WE-SCC series variants if different inductance or current ratings are needed. Verify pin compatibility and mechanical dimensions before substituting with components from other manufacturers to ensure proper fit and function on the existing PCB.
