Overview
The Schaffner RN214-2-02-2M2 is a vertical through-hole common mode filter choke designed for power line applications. It features an inductance of 2.2 mH at 10 kHz and supports a maximum DC current of 2 A. The component has a maximum DC resistance of 70 mOhms, with an inductance tolerance of -30% to +50%. Operating within a temperature range of -40°C to +100°C, it utilizes ferrite core material and measures 23 mm x 15.5 mm x 23 mm.
Feature Summary
- Vertical PCB mount configuration for space-efficient integration
- Current compensated design for effective noise suppression
- Ferrite core construction ensuring stable magnetic performance
Applications
- Power line filtering in electronic equipment
- EMI suppression in industrial control systems
- Noise reduction in AC/DC power supplies
Procurement Notes
Verify the specific part number RN214-2-02-2M2 against manufacturer datasheets to confirm electrical parameters and physical dimensions. Ensure compatibility with existing PCB layouts regarding vertical mounting height and pin spacing. Check for RoHS compliance status as required by project specifications before finalizing procurement orders.
Selection Notes
Select this component when a 2.2 mH inductance value is required for common mode noise attenuation at 10 kHz. The 2 A current rating suits moderate power applications. Consider the vertical form factor for assembly constraints. Verify that the -30% to +50% inductance tolerance aligns with circuit design margins and thermal requirements within the specified operating temperature range.
Part Context
This component belongs to the Schaffner RN series of common mode chokes, engineered for electromagnetic interference suppression. The RN series offers various current and inductance ratings tailored for different power line filtering needs. This specific model provides a balance of high inductance and moderate current capacity for general-purpose EMI mitigation.
Replacement Considerations
Cross-reference with other RN series variants such as RN214-1.5-02-3M3 or RN214-2-02-1M0 if parameter adjustments are needed. Verify pinout compatibility and mechanical footprint before substituting. Consult official Schaffner documentation for equivalent part numbers with similar electrical characteristics.
