0402DF-200XJRW

Fixed Inductors Overview

The Coilcraft 0402DF-200XJRW is a fixed, unshielded wirewound inductor housed in a 0402 (1005 metric) surface-mount package. It provides an inductance of 20 nH with a maximum DC resistance of 49 mOhms and supports a current rating of 1.4 A. The component utilizes ferrite core technology to achieve high impedance for RF isolation while maintaining exceptionally low DC resistance within its ultra-miniature form factor.

Fixed Inductors Feature Summary

• Ferrite-core wirewound construction designed for cellular applications
• Industry-low DC resistance in a 0402 size package
• High impedance characteristics suitable for RF isolation

Fixed Inductors Applications

• Cellular device circuits
• RF isolation networks
• Ground-to-ground filtering applications

Fixed Inductors Procurement Notes

Verify the specific suffix 'XJRW' against manufacturer documentation to confirm RoHS compliance status and lead-free terminal specifications. Ensure the unshielded configuration aligns with the target circuit's electromagnetic interference requirements. Cross-reference the 1.4 A current rating and 49 mOhm DCR limits with system design constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when minimal DC resistance is critical within a 0402 footprint. The unshielded design requires careful layout consideration to manage magnetic field interactions. Verify that the 20 nH value meets the specific frequency response needs of the application, as the lack of shielding may influence performance in dense circuit layouts compared to shielded alternatives.

Fixed Inductors Part Context

This part belongs to the Coilcraft 0402DF series, which features ferrite-core wirewound chip inductors. The series is engineered for high current handling and low resistance in compact spaces. It shares design principles with other Coilcraft ceramic and wirewound lines but distinguishes itself through optimized DCR performance for specific RF and power management use cases.

Fixed Inductors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other 0402DF series variants or comparable unshielded wirewound inductors from alternative manufacturers based on matching 20 nH inductance, 1.4 A current rating, and 49 mOhm DCR specifications.
