Procurement Notes
Verify the specific suffix 'H001' against official TDK documentation to confirm tape and reel packaging specifications and terminal plating details. Ensure the selected variant matches the required operating temperature range and voltage ratings for the target application circuit.
Selection Notes
Select this component when dual-channel filtering is required for low-current data lines. Consider the 22 µH inductance value for appropriate impedance matching. Verify that the 0.25 A current rating exceeds the maximum expected signal current to prevent saturation or overheating during continuous operation.
Part Context
This component belongs to the B82789 series of data and signal line chokes from EPCOS. These components are designed to suppress electromagnetic interference on data lines while maintaining signal integrity. The series offers various inductance values and package options to suit different PCB layout requirements.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains identical inductance, current rating, and physical footprint to guarantee compatibility with existing board designs.
