Procurement Notes
Verify the specific suffix against official TDK documentation to confirm electrical ratings and physical dimensions. Ensure the procurement matches the required rated current and voltage specifications for the target application environment. Confirm compliance with relevant environmental standards before integration.
Selection Notes
Select this component when high current capacity and robust mechanical construction are required for panel-mounted filtering. Consider the physical size constraints due to the cylindrical metal housing. Evaluate thermal management requirements as current ratings are referenced to a specific ambient temperature.
Part Context
This part belongs to the B85321 series of feed-through capacitors manufactured by EPCOS, now part of the TDK Group. These components are specialized passive filters intended for suppressing conducted electromagnetic noise in power lines. The series is engineered for reliability in demanding industrial environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting hardware and circuit parameters before considering alternative sources.
