RN204-2-02-1M1

Overview

The Schaffner RN204-2-02-1M1 is a vertical through-hole common mode choke designed for PCB mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. The component provides an inductance of 1.1 mH at a test frequency of 10 kHz, with a tolerance of -30% to +50%. It supports a maximum DC current of 2 A and has a typical maximum DC resistance of 57 mOhms. The physical dimensions are 14 mm x 9 mm x 14.3 mm, and it carries UL, VDE, and ENEC certifications.

Feature Summary

• Current compensated design for effective noise suppression
• Vertical orientation optimized for printed circuit board integration
• Certified for safety compliance including UL and VDE standards

Applications

• Power supply input filtering
• EMI suppression in electronic equipment
• Signal line protection against common mode interference

Procurement Notes

Verify the specific ordering suffix matches the required inductance and current ratings. Confirm that the vertical package dimensions fit the designated PCB footprint. Ensure the operating environment stays within the specified -40°C to +100°C thermal limits. Check for required safety certifications such as UL or VDE depending on the end-product regulations.

Selection Notes

Select this component when a compact, vertically mounted common mode choke is required for low-current applications. The 2 A rating and 1.1 mH inductance suit general-purpose EMI filtering. Consider the 57 mOhm DCR for power loss calculations. Verify compatibility with automated assembly processes due to the through-hole termination style.

Part Context

This part belongs to the Schaffner RN series of EMC chokes. It is manufactured by TE Connectivity under the Schaffner brand. The series focuses on providing reliable noise filtration for various electronic circuits. The RN204 model specifically addresses space-constrained designs requiring vertical mounting solutions.

Replacement Considerations

Check for direct substitutes within the RN204 series with different inductance values. Verify cross-brand equivalents that match the 1.1 mH inductance and 2 A current rating. Ensure any replacement maintains the same vertical through-hole package dimensions and safety certifications.
