Overview
The Schaffner RN212-4-02 is a current compensated common mode choke designed for through-hole PCB mounting. It features a nominal inductance of 700 µH and supports a maximum DC current of 4 A. The component has a maximum DC resistance of 35 mΩ and operates within a temperature range of -40°C to +100°C. Constructed with ferrite core material, it provides effective electromagnetic interference suppression in compact dimensions.
Feature Summary
- Provides common mode noise attenuation via current compensated choke design
- Supports high current handling up to 4 A for power line applications
- Enables direct through-hole integration onto printed circuit boards
Applications
- Power supply input filtering
- Electromagnetic interference suppression in electronic equipment
- Common mode noise reduction in industrial control systems
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact electrical tolerances and pin configurations. Ensure the selected variant matches the required inductance and current ratings for the target application. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors prior to ordering.
Selection Notes
Select this component when a robust common mode choke is needed for high-current AC/DC lines. Evaluate the 700 µH inductance against system noise frequencies. Consider the 4 A current rating and low DC resistance to minimize power loss. Verify that the through-hole package fits the available PCB layout constraints.
Part Context
The RN212 series represents Schaffner's line of surface-mount and through-hole common mode chokes. These components are engineered for efficient EMI filtering in space-constrained environments. The RN212-4-02 specifically targets applications requiring reliable noise suppression with moderate current capacity.
Replacement Considerations
Cross-reference part numbers such as RN212-4-02-0M7 for variants with specific tolerance markings. Consult manufacturer substitution lists for electrically equivalent components from other suppliers if availability is constrained.
