RN222-1-02-33M

Overview

The Schaffner RN222-1-02-33M is a vertical through-hole common mode choke from the RN series. It features an inductance of 33 mH with a tolerance of -30% to +50%. The component supports a maximum DC current of 1 A and has a maximum DC resistance of 1300 mOhms. It operates within a temperature range of -40°C to +100°C. The physical dimensions are 31 mm x 18 mm x 29.3 mm, utilizing a ferrite core.

Feature Summary

• Provides common mode noise suppression for differential signal lines
• Vertical PCB mount design facilitates compact circuit board integration
• Utilizes ferrite core material for effective electromagnetic interference filtering

Applications

• EMI filtering in power supply input stages
• Signal line protection in industrial control systems
• Noise reduction in telecommunications equipment

Procurement Notes

Verify the specific suffix '33M' confirms the 33 mH inductance value, as other suffixes in the RN222-1-02 series indicate different inductances such as 18 mH or 47 mH. Confirm RoHS compliance status via the official datasheet before procurement. Ensure the vertical pin configuration matches the target PCB footprint requirements.

Selection Notes

Select this component when a 33 mH inductance is required for common mode noise attenuation at 1 A current levels. The 1300 mOhm DC resistance impacts power loss calculations; verify thermal management needs. The vertical package orientation must be accommodated in the mechanical layout. Compare against lower inductance variants if higher current capacity is needed.

Part Context

This part belongs to the Schaffner RN series of common mode chokes, designed for EMI suppression. The RN222-1-02 designation indicates a specific form factor and current rating class within the series. Variants like RN222-0.6-02-47M offer different current and inductance combinations for diverse filtering applications.

Replacement Considerations

RN222-1-02-18M offers 18 mH inductance. RN222-1-02-47M provides 47 mH inductance. Both share the same 1 A current rating and physical dimensions but differ in magnetic performance.
