Power Line Filter Modules Procurement Notes

Verify the specific suffix R725 against official TDK documentation to confirm exact mechanical dimensions and terminal configuration. Ensure the application environment temperature does not exceed the specified +55°C operating limit. Confirm that the 30 A current rating aligns with the system's maximum load requirements to prevent thermal overload during continuous operation.

Power Line Filter Modules Selection Notes

Select this component when single-phase EMI filtering is required for high-current applications up to 30 A. Consider the terminal block interface if PCB mounting is not feasible. Verify compatibility with 250 VAC/DC systems and ensure the installation space accommodates the module's physical footprint while maintaining adequate airflow for thermal management within the +55°C limit.

Power Line Filter Modules Part Context

This component belongs to the B84742A series of power line filters from TDK Electronics, formerly known as EPCOS. The series is designed for robust performance in demanding industrial and data technology applications. TDK acquired EPCOS, integrating these filter modules into its broader portfolio of electronic components for noise suppression and power integrity.

Power Line Filter Modules Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may differ in leakage current or insertion loss characteristics. Ensure any replacement maintains the same 30 A rating and 250 VAC specification to preserve system safety and compliance.
