Overview
The Schaffner RN204-0.3-02-22M is a vertical through-hole common mode filter choke from the RN series, designed for PCB mounting. It features an inductance of 22 mH with a tolerance of -30% to +50%. The component supports a maximum DC current of 0.3 A and has a maximum DC resistance of 1.3 ohms. It operates within a temperature range of -40°C to +100°C and is rated for 300 VAC/DC. The unit utilizes a ferrite core and is unshielded, suitable for EMI suppression in compact electronic assemblies.
Feature Summary
- Vertical PCB mount design for space-efficient integration
- Ferrite core construction for effective common mode noise attenuation
- RoHS compliant manufacturing standards
Applications
- Power supply input filtering
- EMI suppression in consumer electronics
- Industrial control circuit protection
Procurement Notes
Verify the manufacturer part number RN204-0.3-02-22M against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the specific batch meets RoHS requirements if mandated by your project specifications. Cross-reference the electrical parameters, particularly the 22 mH inductance and 0.3 A current rating, with your schematic requirements before finalizing procurement decisions.
Selection Notes
Select this component when a vertical orientation is required for board layout constraints. Ensure the application current does not exceed 0.3 A to prevent saturation or overheating. Verify that the 1.3 ohm DC resistance aligns with your voltage drop limitations. Consider the -40°C to +100°C operating range against your environmental conditions.
Part Context
This component belongs to the Schaffner RN series of common mode chokes, which are widely used for electromagnetic interference (EMI) filtering in various electronic devices. The series offers standardized footprints and electrical characteristics to simplify design-in processes for engineers requiring reliable noise suppression solutions in power lines.
Replacement Considerations
Consult official Schaffner or TE Connectivity substitution guides for verified equivalents. Do not assume generic inductors are compatible due to potential differences in core material, saturation current, or physical dimensions.
