Fixed Inductors Procurement Notes

Verify RoHS compliance status as the component is marked non-compliant. Confirm lead availability through authorized distributors, as stock levels may vary. Ensure ordering quantities align with manufacturer reel requirements. Validate terminal type compatibility with target PCB footprint before procurement.

Fixed Inductors Selection Notes

Select this component for designs requiring precise 270 nH inductance with tight ±2% tolerance. Consider the 890 mA current rating against circuit load requirements. Evaluate the 240 MHz self-resonant frequency to ensure operation remains below the resonant point. Verify that the unshielded design does not interfere with adjacent sensitive components.

Fixed Inductors Part Context

This part belongs to the 4302/R series of RF inductors manufactured by Delevan. The series provides various inductance values within the same 1008 package form factor. It serves as a specialized passive component for radio frequency electronics, distinct from general-purpose power inductors.

Fixed Inductors Replacement Considerations

Cross-reference with other 4302 series variants such as 4302-271F or 4302-271K for different tolerance options. Ensure substitute parts match the 1008 package dimensions and 270 nH nominal value.
