Overview
The RI403PC is a saturating type common mode choke manufactured by Schaffner EMC Inc. Designed for through-hole mounting, this component operates within a temperature range of -25°C to 110°C. It functions as an electromagnetic interference suppression element, utilizing a saturating core design to manage noise in electrical circuits.
Feature Summary
- Saturating core design enables impedance variation during switching events
- Effective attenuation of differential-mode noise components
- Through-hole construction suitable for standard PCB assembly processes
Applications
- Power supply input filtering
- Motor drive circuit protection
- Industrial control system noise suppression
Procurement Notes
Verify the specific manufacturer part number RI403PC against official Schaffner or TE Connectivity documentation to confirm current availability and technical specifications. Ensure that the through-hole footprint and thermal ratings align with the target application requirements before finalizing procurement decisions.
Selection Notes
Select this component when differential-mode noise attenuation is required during switching transitions. The saturating characteristic distinguishes it from linear chokes, making it suitable for applications where impedance changes dynamically. Confirm that the operating temperature range meets the environmental conditions of the intended installation.
Part Context
RI403PC belongs to the Schaffner EMC product portfolio, which specializes in electromagnetic compatibility solutions. The company provides a broad range of filters and chokes for industrial and commercial applications. This specific part represents a passive component designed for integration into larger electronic systems requiring noise mitigation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-compatibility with existing designs using detailed electrical parameter matching rather than generic family replacements.
