RN212-0.5-02

Overview

The Schaffner EMC Inc. RN212-0.5-02 is a vertical through-hole common mode choke from the RN series, designed for PCB mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. The component supports a maximum DC current of 0.5 A with a maximum DC resistance of 15 mOhms. Inductance is specified at 15 mH with tolerances of -30% and +50%. Measuring 18 mm x 12.5 mm x 20 mm, it is unshielded and rated for 300 VDC.

Feature Summary

• Provides electromagnetic interference suppression via common mode filtering
• Utilizes a ferrite core for high inductance performance
• Designed for vertical printed circuit board mounting

Applications

• Power supply input filtering
• Electromagnetic compatibility circuits
• RFI suppression in electronic equipment

Procurement Notes

Verify the specific inductance value against the datasheet, as the RN212-0.5-02 designation corresponds to 15 mH, while similar suffixes like 27M indicate different values. Confirm RoHS compliance status and physical dimensions match the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 0.5 A current rating and 15 mH inductance are required for vertical mounting applications. Ensure the operating environment stays within the -40°C to +100°C range. Consider the unshielded nature of the device regarding spatial constraints and potential coupling effects in dense layouts.
