Overview
The Schaffner RD7147-16-1M5 is a current-compensated common mode choke designed for phase-angle control circuits. It features a dual-choke configuration with four channels, supporting a rated current of 16 A per path and an inductance of 1.5 mH. The component operates at a maximum continuous voltage of 600 VAC or 850 VDC. Key electrical parameters include a maximum DC resistance of 8.5 mΩ and a lead diameter of 1.8 mm. It is suitable for applications requiring robust EMI suppression in high-current environments.
Feature Summary
- Current-compensated design for effective noise reduction
- Four-channel configuration for multi-phase applications
- Suitable for phase-angle control circuits
Applications
- Phase-angle control circuits
- Industrial power supplies
- Motor drives
Procurement Notes
Verify the specific manufacturer designation, as sources list both TE Connectivity / Schaffner and Schaffner EMC Inc. Confirm the exact datasheet version to ensure alignment with the 8.5 mΩ resistance and 1.5 mH inductance values. Check for any recent product lifecycle changes or obsolescence notices from authorized distributors before finalizing procurement plans.
Selection Notes
Select this component for applications requiring 16 A current handling with 1.5 mH inductance. Ensure the operating voltage does not exceed 600 VAC or 850 VDC. Verify that the physical dimensions and mounting requirements match the PCB layout. Consider the thermal performance under continuous load conditions to ensure reliability within the specified temperature range.
Part Context
The RD series represents a line of current-compensated common mode chokes from Schaffner. These components are engineered for high-performance EMI filtering in demanding industrial and medical applications. The RD7147-16-1M5 specifically targets phase-control systems where high current capacity and precise inductance are critical for maintaining signal integrity and compliance.
Replacement Considerations
The B82765C1A5 is identified as an obsolete part for which the RD7147-16-1M5 serves as a primary substitute option. Verify mechanical fit and electrical equivalence before substitution.
