CPEX2017L-3R3MC

Fixed Inductors Overview

The CPEX2017L-3R3MC is a fixed wirewound inductor from the CODACA CPEX series, designed for high-current applications. It features a vertical through-hole package with two PC pins and measures 0.787 inches in length. The component has an inductance of 3.3 µH with a ±20% tolerance and a maximum DC resistance (DCR) of 1.2 mΩ. It supports a continuous current rating of 55 A and a saturation current of up to 290 A. Operating within a temperature range of -55°C to +155°C, it utilizes flat wire winding and magnetic shielding to minimize losses and EMI.

Fixed Inductors Feature Summary

• Flat wire winding design for low DCR and high efficiency
• Soft saturation characteristic for handling peak currents
• Magnetic shielded structure for EMI reduction
• High thermal stability across wide temperature ranges

Fixed Inductors Applications

• PV inverters
• Industrial power supplies
• High-power density converters

Fixed Inductors Procurement Notes

Verify the specific suffix 'L' indicates the low DCR variant within the CPEX family. Confirm that the vertical through-hole mounting style matches the PCB layout requirements. Ensure the operating temperature range aligns with the system's thermal environment. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material specifications before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when high current handling and low core loss are critical. The flat wire construction offers superior performance compared to round wire equivalents in similar footprints. Consider the soft saturation profile for applications with significant current ripple. Verify that the 55 A RMS rating meets the continuous load requirements while accounting for ambient temperature derating.

Fixed Inductors Part Context

This part belongs to the CPEX series of super high-current inductors developed by CODACA. The series utilizes proprietary metal composite core materials and flat wire technology to achieve high power density. The 'L' designation typically denotes a low DCR optimization within the product line, distinguishing it from standard or high-saturation variants.

Fixed Inductors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 3.3 µH inductance, 55 A current rating, and vertical through-hole package dimensions. Consult the manufacturer for potential obsolescence management or alternative series recommendations.
