Overview
The Schaffner EMC Inc. RN232-1-02-18M is a common mode choke designed for electromagnetic interference suppression. It features an inductance of 18 mH and a rated current of 1 A with a DC resistance of 390 mOhms. The component utilizes vertical through-hole mounting and supports frequencies from DC to 400 Hz. It is constructed for robust performance within standard industrial environments.
Feature Summary
- Provides effective common-mode noise attenuation for power lines
- Supports frequency range from DC up to 400 Hz
- Utilizes vertical through-hole termination for secure board integration
Applications
- Power supply input filtering
- Electromagnetic compatibility (EMC) circuits
- Industrial equipment noise suppression
Procurement Notes
Verify the exact part number against manufacturer documentation to ensure correct inductance and current ratings. Confirm that the vertical through-hole package matches the target PCB footprint. Check RoHS compliance status if required by specific regulatory standards. Ensure the operating temperature range aligns with the application environment.
Selection Notes
Select this component when a 18 mH inductance at 1 A is required for common mode noise reduction. The vertical form factor suits applications with limited board space but available height clearance. Verify that the 390 mOhm DC resistance meets the voltage drop constraints of the circuit design.
Part Context
This component belongs to the Schaffner RN series of common mode chokes, which are engineered for general-purpose EMI filtering. The series offers various inductance and current ratings to suit different power line requirements. These chokes are widely used in electronic devices to meet regulatory emission limits.
Replacement Considerations
Direct substitutes must match the 18 mH inductance, 1 A rating, and vertical through-hole package. Verify equivalent DC resistance and frequency response characteristics. Cross-reference with other manufacturers' common mode chokes offering identical electrical parameters and mechanical dimensions.
