RN222-1-02

Overview

The Schaffner RN222-1-02 is a through-hole common mode choke filter designed for printed circuit board mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical specifications include an inductance of 18 mH, a maximum DC current rating of 1 A, and a maximum DC resistance of 630 mOhms. The component has a tolerance of -30% to +50% and is tested at a frequency of 10 kHz. Its physical dimensions are 27 mm x 28 mm x 16.5 mm.

Feature Summary

• Attenuates common-mode or asymmetric interference signals when connected in series with the phase
• Utilizes a ferrite core for effective electromagnetic noise suppression
• Designed for vertical PCB mounting via through-hole termination

Applications

• Series connection with phase lines for EMI attenuation
• Power supply input filtering
• Electronic equipment noise suppression

Procurement Notes

Verify the specific part number suffix against official TE Connectivity/Schaffner documentation to ensure correct inductance and current ratings. Confirm RoHS compliance status and lead-free requirements prior to procurement. Cross-reference datasheet parameters such as DC resistance and operating temperature range with system design constraints to guarantee compatibility.

Selection Notes

Select this component based on the required 18 mH inductance and 1 A current handling capability. Ensure the PCB layout accommodates the specified vertical footprint dimensions. Consider the -30% to +50% inductance tolerance during circuit design to account for manufacturing variations. Verify that the operating environment stays within the -40°C to +100°C thermal limits.
