• Common mode noise reduction in four-line power circuits

Procurement Notes

Verify the specific datasheet version to confirm inductance values, as sources indicate both 0.3 mH and 210 µH @ 100 kHz. Ensure the horizontal mounting orientation and radial terminal type match the target PCB layout. Confirm voltage ratings and temperature ranges align with the operational environment requirements before finalizing procurement.

Selection Notes

Select this component when a four-line common mode choke with high current capacity is required. The horizontal form factor suits space-constrained PCB designs. Verify that the MnZn core characteristics meet the specific frequency response needs for the application's noise spectrum.

Part Context

This part belongs to the Schaffner RV series of EMC chokes. It is designed for board mount applications requiring robust filtering performance. The series typically offers various current ratings and inductance values to accommodate different power line filtering requirements across industrial and commercial electronics.

Replacement Considerations

Cross-reference with other RV8140 variants such as RV8140-25-S11 or RV8140-16-S11 if lower current ratings are acceptable. Verify pinout and mechanical dimensions to ensure compatibility with existing footprints.
