Overview
The Schaffner RC112-0.7-4M7 is a common mode choke from the RC series, designed for attenuating asymmetric interference signals. It features an inductance of 4.7 mH and a maximum DC current rating of 700 mA. The component has a maximum DC resistance of 0.44 ohms and operates within a temperature range of -40°C to 125°C. Rated for AC voltages up to 250 V, it utilizes through-hole termination with solder pads. The physical dimensions are compact, facilitating integration into various electronic assemblies requiring EMI suppression.
Feature Summary
- Attenuates common-mode or asymmetric interference signals
- Designed for power-line filtering applications
- Supports through-hole mounting via solder pads
Applications
- Electromagnetic compatibility (EMC) design in power supplies
- EMI suppression in electronic equipment input stages
- Filtering asymmetric noise in signal lines
Procurement Notes
Verify the manufacturer designation as TE Connectivity / Schaffner EMC Inc. when sourcing. Confirm the specific part number RC112-0.7-4M7 matches the required 4.7 mH inductance and 700 mA current rating. Ensure the operating temperature range of -40°C to 125°C meets your environmental specifications. Check for RoHS compliance details if required by your assembly standards.
Selection Notes
Select this component when asymmetric interference attenuation is required in low-current circuits. The 700 mA rating suits applications where higher current chokes are unnecessary. Verify that the 0.44 ohm DC resistance does not introduce excessive voltage drop in your circuit design. Ensure the through-hole package fits your PCB layout constraints.
Part Context
This component belongs to the Schaffner RC series of common mode chokes. These components are engineered for EMC/EMI product applications, focusing on the suppression of electromagnetic interference. The RC series provides standardized solutions for filtering asymmetric noise in electronic systems, supporting compliance with electromagnetic compatibility regulations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching inductance, current rating, and physical footprint. Consult official Schaffner or TE Connectivity catalogs for verified alternatives.
