RN222-1-02-18M

Overview

The Schaffner RN222-1-02-18M is a through-hole common mode choke designed for PCB mounting. It features an inductance of 18 mH with a tolerance of -30% to +50%. The component supports a maximum DC current of 1 A and has a maximum DC resistance of 630 mOhms. It operates within a temperature range of -40°C to +100°C. The vertical package dimensions are approximately 27 mm x 28 mm x 16.5 mm. It utilizes ferrite core material and is unshielded.

Feature Summary

Provides effective common mode noise suppression for electromagnetic interference mitigation
Utilizes a vertical through-hole mounting style for secure PCB integration
Constructed with ferrite core material for stable magnetic performance

Applications

Power supply circuits requiring EMI filtering
Battery charger systems
Portable electronic devices
Energy-efficient system designs

Procurement Notes

Verify the complete part number including suffixes against official TE Connectivity or Schaffner documentation to ensure correct specifications. Confirm that the required inductance, current rating, and physical dimensions align with your design constraints before ordering. Cross-reference manufacturer datasheets for accurate RoHS compliance status and approval agency details such as VDE or UR.

Selection Notes

Select this component when a 18 mH inductance at 1 A current rating is required for common mode noise reduction. Ensure the vertical form factor fits the available PCB real estate. Verify that the unshielded design does not interfere with nearby sensitive components. Check that the operating temperature range meets the environmental requirements of the final application.

Part Context

This component belongs to the RN series of common mode chokes manufactured by TE Connectivity / Schaffner. The series offers various inductance and current combinations for EMC applications. The RN222-1-02-18M specifically targets applications needing moderate inductance with higher current handling capabilities compared to lower-rated variants in the same family.

Replacement Considerations

Direct substitutes may include other RN series parts with similar electrical characteristics. Verify compatibility by comparing inductance, current rating, and physical footprint. Consult official cross-reference lists from TE Connectivity for confirmed equivalent part numbers.
