CSQX2918H-2R7MC

Fixed Inductors Overview

The CSQX2918H-2R7MC is a shielded wirewound power inductor from the CODACA CSQX series, designed for high-current applications. It features a nominal inductance of 2.7 µH with a tolerance of ±20%. The component supports a maximum DC current of 41.0 A and exhibits a saturation current (Isat) of 170 A. Its maximum DC resistance (DCR) is specified at 1.40 mΩ. The device utilizes a vertical mounting configuration with three PC pins and operates within a temperature range of -55°C to +155°C.

Fixed Inductors Feature Summary

• High saturation current capability up to 170 A for stable operation under peak loads
• Low DC resistance design minimizing conduction losses and heat generation
• Shielded wirewound construction ensuring magnetic field containment and EMI reduction
• Soft saturation characteristic maintaining inductance stability during current spikes

Fixed Inductors Applications

• DC-DC converters requiring high power density
• Large current switching regulators
• Industrial control power supplies
• New energy system power management modules

Fixed Inductors Procurement Notes

Verify the specific saturation and RMS current ratings against the official datasheet before integration, as these values are critical for thermal management. Confirm that the vertical pin spacing matches the target PCB footprint. Ensure the selected variant aligns with the required inductance tolerance for the circuit's ripple specifications. Cross-reference the operating temperature range with the environmental conditions of the final assembly.

Fixed Inductors Selection Notes

Select this component when the application demands high current handling with minimal voltage drop across the inductor. The 2.7 µH value suits intermediate frequency switching applications where compact size is prioritized. Consider the soft saturation profile if the load experiences frequent transient currents. Compare DCR requirements against other series options if lower resistance is needed, noting that different suffixes may indicate varying electrical characteristics within the same physical package.

Fixed Inductors Part Context

This part belongs to the CSQX series of super high-current inductors manufactured by CODACA. The series employs proprietary metal powder core materials and flat wire winding technology to achieve high efficiency and low loss. The CSQX2918H designation indicates a specific size code optimized for high saturation performance compared to standard variants. It serves as a surface-mount alternative to through-hole designs like the CPQX series while offering comparable magnetic shielding benefits.

Fixed Inductors Replacement Considerations

Direct substitutes include other CSQX2918H variants with similar inductance values, such as CSQX2918H-3R9MC or CSQX2918H-4R7MC, provided their current ratings meet the circuit requirements. Verify pin compatibility and inductance tolerance when swapping between models. Consult the manufacturer's comparison tables for DCR and Isat differences to ensure functional equivalence.
