Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS3 regulations if required by the target application. Confirm availability status directly with authorized distributors as stock levels fluctuate. Cross-reference the part number with the latest revision history to ensure no functional changes have occurred.

Fixed Inductors Selection Notes

Select this component when a 390 nH inductance value is required in a compact 0603 footprint. Consider the 100 mA current rating and 4.35 Ohm DCR for power loss calculations in low-current signal paths. The unshielded nature requires layout consideration to minimize electromagnetic interference coupling with nearby traces. Verify that the 900 MHz self-resonant frequency aligns with the operating frequency of the circuit.

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 range of inductance values from 1.5 nH to 470 nH, designed for use in mobile, industrial, and IoT market segments. These components are characterized by their small size and suitability for high-frequency applications requiring precise inductance control.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0603 unshielded drum core inductors with 390 nH ±2% tolerance and similar current ratings. Equivalent parts from other manufacturers must match the 0603 footprint dimensions and operate within the -40°C to 125°C temperature range. Verify that alternative components maintain comparable self-resonant frequencies to ensure circuit performance integrity.
