Fixed Inductors Procurement Notes

Verify the exact inductance value against official datasheets, as distributor listings may contain conflicting data regarding nanohenry versus microhenry specifications. Confirm package dimensions and terminal wraparound requirements match PCB layout constraints. Ensure compliance with RoHS3 standards and check moisture sensitivity level classifications prior to soldering. Cross-reference part numbers carefully to avoid confusion with similar series variants.

Fixed Inductors Selection Notes

Select this component when a 3.3 µH inductance value is required within an unshielded SMD form factor. Consider the 310 mA current rating and 1.4 Ohm DCR for power loss calculations. Evaluate the 40 MHz self-resonant frequency limit to ensure suitability for the target signal bandwidth. Compare thermal performance against the -40°C to 125°C range for environmental compatibility.

Fixed Inductors Part Context

This part belongs to the Delta Electronics 0805CS series of fixed wirewound inductors.
