Overview
The Schaffner RC212-0.35-22M is a through-hole common mode choke from the RC series, designed for PCB mounting. It features an inductance of 22 mH and supports a maximum DC current of 0.35 A. The component has a maximum DC resistance of 1.9 ohms and operates within a temperature range of -40°C to +125°C. Rated for 250VAC, it provides single-channel filtering with vertical orientation.
Feature Summary
- Provides high-performance electromagnetic interference (EMI) and radio frequency interference (RFI) suppression through current-compensated design.
Applications
- Power supply input filtering
- DC-DC converter noise reduction
- General EMI suppression in electronic circuits
Procurement Notes
Verify the manufacturer part number RC212-0.35-22M against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the specified electrical parameters, including 22 mH inductance and 0.35 A current rating, match your circuit requirements before procurement.
Selection Notes
Select this component when vertical PCB mounting is required for space-constrained designs. Ensure the application voltage does not exceed 250VAC and the operating current remains below 0.35 A. Verify thermal management capabilities given the 1.9 ohm DC resistance and 125°C maximum operating temperature.
Part Context
This component belongs to the Schaffner RC series of common mode chokes, manufactured by TE Connectivity / Schaffner. These components are engineered for EMC/RFI applications, offering reliable filtering solutions for various electronic systems requiring compact, through-hole mounted inductors.
Replacement Considerations
Consult official datasheets for direct substitutes. Potential alternatives may include other Schaffner RB series chokes with similar inductance and current ratings, provided pin configurations and physical dimensions are compatible.
