RS612-4-02

Overview

The Schaffner RS612-4-02 is a radial common mode inductor from the RS612 series, designed for electromagnetic interference suppression. It features an inductance of 55 µH and supports a maximum DC current of 1 A. The component utilizes PC pin termination with a lead pitch of 3.78 mm and a lead diameter of 0.3 mm. Physical dimensions include a height of 2.3 mm and a width of 3.3 mm. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides effective common mode noise attenuation for sensitive electronic circuits
• Compact radial design facilitates efficient PCB layout and space-constrained applications
• Robust thermal stability ensures reliable operation across wide industrial temperature ranges

Applications

• Power supply input filtering
• Switching converter noise suppression
• Audio equipment signal integrity protection

Procurement Notes

Verify the specific part number RS612-4-02 against official Schaffner documentation to confirm current availability and manufacturing status. Ensure that the 55 µH inductance and 1 A current rating align precisely with the circuit requirements. Cross-reference lead dimensions and pitch to guarantee mechanical compatibility with the target printed circuit board footprint before finalizing procurement orders.

Selection Notes

Select this component when low-profile radial mounting is required for common mode chokes. The 55 µH value suits moderate frequency noise suppression tasks. Verify that the 1 A current handling capacity meets the operational load without saturation. Confirm that the 3.78 mm lead pitch matches the existing board design to avoid rework or custom adapter usage during assembly integration.

Part Context

This component belongs to the RS612 series of common mode chokes manufactured by Schaffner EMC Inc. The series is engineered for general-purpose EMI filtering in compact electronic devices. It complements other Schaffner filter solutions by offering a through-hole alternative for applications where surface mount components are unsuitable due to height restrictions or mechanical stress requirements.

Replacement Considerations

Consult official Schaffner substitution guides for verified equivalents. Generic cross-references may not match the precise 55 µH inductance or 1 A current rating. Ensure any substitute maintains the same radial package dimensions and lead pitch to fit the existing PCB layout without modification.
