Power Line Filter Modules Procurement Notes

Verify the complete part number including suffixes against official TDK-EPCOS documentation to ensure correct configuration. Confirm that the required current rating of 400A and voltage specifications match the target application's electrical parameters. Check for any specific ordering code variations or alternative series designations that may indicate different performance characteristics or housing types.

Power Line Filter Modules Selection Notes

Select this component when designing systems with three-phase inputs requiring significant current handling capabilities. Ensure the installation environment allows for chassis mounting and provides adequate clearance for heat dissipation given the operational temperature range. Validate that the system's peak voltage does not exceed the specified withstand limits during transient conditions.

Power Line Filter Modules Part Context

This model belongs to the B84143B/K*S080/S081 series of three-line filters manufactured by EPCOS (TDK).
