Overview
The Schaffner RN112-2.6-02-0M4 is a common mode choke from the RN series, rated for a maximum current of 2.6 A and an inductance of 400 uH. It operates at a test frequency of 10 kHz with a maximum voltage of 300 VDC. The component features PCB terminal termination and measures 17.7 x 17.1 x 12.6 mm. It supports a pollution degree of 400 and functions within standard industrial temperature ranges.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Utilizes ferrite core technology for effective EMI filtering
- Designed for through-hole PCB mounting applications
Applications
- Electromagnetic interference suppression in electronic circuits
- Signal line protection in industrial equipment
- Power supply input filtering stages
Procurement Notes
Verify the specific inductance tolerance and DC resistance values against the official Schaffner datasheet before integration. Confirm that the 300 VDC rating aligns with your system's operational voltage requirements. Ensure the through-hole footprint dimensions match your PCB layout constraints to avoid mechanical interference during assembly.
Selection Notes
Select this component when a 400 uH common mode inductance is required for currents up to 2.6 A. Consider the physical dimensions of 17.7 x 17.1 x 12.6 mm for spatial planning. Evaluate the 10 kHz test frequency relevance to your target noise spectrum. Verify compatibility with your manufacturing process for through-hole termination styles.
Part Context
This part belongs to the Schaffner RN series of common mode chokes, designed for general EMC/RFI suppression. The RN series typically offers compact solutions for circuit protection. This specific model variant provides balanced performance for moderate current applications requiring reliable noise attenuation in dense electronic assemblies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching inductance, current rating, and physical footprint specifications from alternative manufacturers.
