Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and tolerance specifications. Confirm that the required current rating and impedance values align with the target circuit design before finalizing procurement orders. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Fixed Inductors Selection Notes

Select this component when a 120 nH inductance is required in a 0603 footprint with minimal physical size constraints. Consider the 6 GHz self-resonant frequency limit to ensure operation remains below the resonance point for effective filtering or matching. Evaluate the 300 mA current rating against peak load conditions to prevent saturation or thermal issues during continuous operation.

Fixed Inductors Part Context

This part belongs to the 0603CS series of ceramic RF inductors manufactured by Delta Electronics/Components. The series covers a wide inductance range from 1.5 nH to 470 nH, providing options for various RF circuit designs. These components are characterized by their small form factor and high-quality ceramic materials, making them suitable for space-constrained mobile and industrial electronics.

Fixed Inductors Replacement Considerations

Consult official Delta Electronics documentation for direct cross-references. Verify that any substitute maintains the 120 nH nominal value, 0603 package dimensions, and equivalent 6 GHz self-resonant frequency to preserve circuit performance.
