Overview
The Schaffner RN122-1-02-10M is a horizontal through-hole common mode choke from the RN series. It features an inductance of 10 mH and a maximum DC current rating of 1 A. The component has a maximum DC resistance of 560 mOhms and operates within a temperature range of -40°C to +100°C. Measuring 27 mm x 28 mm x 16.5 mm, it utilizes a ferrite core and is unshielded.
Feature Summary
- Horizontal surface mount configuration with four PCB pins for secure board attachment
- Current compensated design utilizing ferrite core technology
- Unshielded construction suitable for standard electromagnetic interference suppression
Applications
- Power supply input filtering
- Battery charger circuits
- Portable electronic devices
- Energy-efficient system noise reduction
Procurement Notes
Verify the specific part number RN122-1-02-10M against official TE Connectivity or Schaffner datasheets to confirm electrical parameters. Ensure compatibility with existing PCB footprint dimensions and thermal requirements before procurement. Cross-reference manufacturer documentation for any recent revisions or obsolescence notices.
Selection Notes
Select this component when a 10 mH inductance at 1 A is required for common mode noise suppression. The horizontal form factor aids in space-constrained layouts. Verify that the 560 mOhm DC resistance meets circuit efficiency targets and that the operating temperature range aligns with the application environment.
Part Context
This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series offers various inductance values and current ratings designed for EMI/RFI suppression in electronic circuits. The RN122-1-02-10M specifically provides a balance of high inductance and moderate current handling.
Replacement Considerations
RN122-1-02-18M: Offers 18 mH inductance with 1 A current rating. RN122-1-02-10M: Current selection. RN112-2-02-1M0: Different series with 1 mH inductance and 2 A current rating.
