Overview
The Schaffner RN214-2-02 is a current-compensated common mode choke belonging to the RN series. It features a ferrite core and unshielded construction designed for through-hole PCB mounting. The component supports a maximum DC current of 2 A with a maximum DC resistance of 74 mΩ. It operates within a temperature range of -40°C to +100°C and has physical dimensions of 23.00 mm x 15.00 mm x 20.00 mm.
Feature Summary
- Provides common mode noise suppression via current-compensated choke design
- Utilizes a ferrite core for effective electromagnetic interference filtering
- Supports vertical through-hole PCB mounting for secure installation
Applications
- Power line filtering in electronic equipment
- EMI suppression in industrial control systems
- Noise reduction in AC/DC power supply circuits
Procurement Notes
Verify the specific inductance value required, as datasheets for the RN214 series often list variants with different ratings (e.g., 6.8 mH or 2.2 mH). Confirm that the 2 A current rating aligns with your circuit's operational requirements. Ensure the through-hole package dimensions fit your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a 2 A rated common mode choke is needed for vertical PCB integration. Compare against other RN series models if higher current capacity or different inductance values are required. Consider the unshielded nature of the device regarding spatial layout and proximity to sensitive components during board design.
Part Context
This part belongs to the Schaffner RN series of common mode chokes, manufactured by TE Connectivity / Schaffner. These components are widely used for EMI suppression in power applications. The RN214 variant specifically denotes a through-hole package style within this family, distinct from surface mount options.
Replacement Considerations
RN214-2-02-2M2 is a confirmed substitute with identical 2 A rating and similar dimensions. Verify inductance tolerance (-30%, +50%) and lead pitch compatibility when substituting.
