Procurement Notes
Verify the specific ordering suffix against official TDK Electronics documentation to ensure correct voltage and current ratings. Confirm package dimensions and terminal specifications match the mechanical constraints of the target assembly. Request updated datasheets directly from authorized distributors or the manufacturer to validate compliance with current RoHS and REACH standards before finalizing procurement orders.
Selection Notes
Select this component when high-current EMI filtration is required for single-phase AC systems. Ensure the operating environment stays within the specified -40°C to 85°C range. Verify that the 63A rated current aligns with the maximum load requirements of the application circuit to prevent thermal overload during continuous operation.
Part Context
This part belongs to the B85321 series of feedthrough filters designed for noise suppression in electrical networks. These components are integral to maintaining signal integrity and protecting sensitive electronics from conducted disturbances in industrial and commercial power distribution systems.
Replacement Considerations
Consult official substitution lists for compatible EMI filters with matching current and voltage ratings. Verify mechanical compatibility of threaded terminals before replacing.
