CPEX2022S-4R0MC

Fixed Inductors Overview

The CPEX2022S-4R0MC is a fixed shielded wirewound inductor from the CODACA CPEX series, designed for high-current applications. It features a vertical package with two PC pins and a 2022 footprint. The nominal inductance is 4 µH with a ±20% tolerance. Key electrical parameters include a rated current of 38.5 A, a saturation current (Isat) of 42 A, and a maximum DC resistance (DCR) of 1.51 mΩ. It operates within a temperature range of -55°C to 155°C.

Fixed Inductors Feature Summary

• Utilizes flat wire winding technology to achieve very low DC resistance and minimize coil losses.
• Features a magnetic shield structure that provides excellent resistance to electromagnetic interference (EMI).
• Demonstrates soft saturation characteristics and high DC bias capability to handle instantaneous peak currents.

Fixed Inductors Applications

• High-density power supply modules requiring large current handling.
• DC/DC converters for entertainment and navigation systems.
• Noise suppression circuits for automotive motors and actuators.

Fixed Inductors Procurement Notes

Verify the specific suffix 'MC' against the manufacturer's official documentation to confirm exact tolerance and packaging specifications. Ensure the ordering part number matches the required inductance value and current ratings for your circuit design. Cross-reference the package dimensions with your PCB layout constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact form factor is required alongside high current capacity. The flat wire construction offers superior performance compared to round wire equivalents of similar size. Consider the soft saturation profile for applications experiencing significant DC bias conditions where maintaining inductance stability is critical.

Fixed Inductors Part Context

This component belongs to the CPEX series of super high-current inductors manufactured by CODACA Electronic. The series utilizes proprietary alloy powder cores and flat wire winding techniques to reduce volume while increasing power density. This specific model represents a standard product offering within the S-series lineup.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4 µH inductance, 2022 footprint, and comparable current ratings. Verify that alternative components support vertical mounting and possess similar shielding characteristics to ensure EMI compatibility in the existing assembly.
