Overview
The RN218-2.2-02-3M3 is a common mode choke from the Schaffner RN series, designed for PCB mounting via through-hole termination. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical parameters include an inductance of 3.3 mH with tolerances of -30% and +50%, a maximum DC current rating of 2.2 A, and a maximum DC resistance of 102 mOhms. The component measures 18 mm x 12.5 mm x 20 mm.
Feature Summary
- Provides common mode noise suppression for signal lines
- Utilizes a ferrite core for effective EMI filtering
- Designed for vertical PCB mounting applications
Applications
- Medical device EMC/EMI components
- Signal line filtering in electronic equipment
- General purpose common mode choke applications
Procurement Notes
Verify the manufacturer designation as TE Connectivity / Schaffner or Schaffner EMC Inc. on official datasheets. Confirm RoHS compliance status and specific tolerance ranges (-30%, +50%) against the latest product documentation. Ensure the package dimensions (18 mm x 12.5 mm x 20 mm) match your board layout requirements before finalizing procurement.
Selection Notes
Select this component when a 3.3 mH inductance at 2.2 A is required for common mode noise reduction. The through-hole vertical mount style suits designs needing robust mechanical fixation. Verify that the operating temperature range of -40°C to +100°C meets environmental constraints. Check if the unshielded design aligns with spatial and interference requirements.
Part Context
This part belongs to the RN series of EMC/EMI components offered by Schaffner. These components are specifically engineered for medical devices and other sensitive electronics requiring reliable noise suppression. The series covers various current ratings and voltage ranges, positioning this choke as a solution for mid-range current signal line protection.
Replacement Considerations
Cross-reference with RN212-1.5-02-3M3 for lower current applications. Verify compatibility with RN218-0.7-02-39M if different inductance values are needed. Always confirm pinout and dimensional compatibility with alternative parts from the same family.
