Power Line Filter Modules Procurement Notes

Verify the complete part number including the suffix R190 to ensure correct termination style and certification compliance. Confirm voltage ratings match system requirements before integration. Check RoHS status and REACH declarations against specific project constraints. Validate physical dimensions for chassis cutout compatibility during mechanical design phases.

Power Line Filter Modules Selection Notes

Select this component when high current handling up to 55 A is required in a single-phase configuration. Ensure the 1 kVDC rating aligns with the maximum DC bus voltage of the application. Consider the 7.7 mA leakage current limit for sensitive medical or precision instrumentation environments where lower leakage might be necessary.

Power Line Filter Modules Part Context

This filter belongs to the B84742A series designed for industrial power applications. TDK Electronics acquired EPCOS, integrating these components into their broader portfolio. The series supports renewable energy and industrial sectors requiring reliable EMI suppression in compact chassis-mounted formats.

Power Line Filter Modules Replacement Considerations

Consult official TDK documentation for direct cross-references within the B84742A family. Verify that substitute models maintain identical terminal block configurations and certified voltage ratings.
