Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required operating temperature range and current ratings for the target application environment. Cross-reference part numbers with authorized distributors to validate authenticity and compliance with current RoHS standards.

Fixed Inductors Selection Notes

Select this component when a 3.3 µH inductance value is required with a ±1% tolerance for precision RF circuits. Consider the 187 mA current rating and 1.35 Ohm DC resistance limits during thermal and power analysis. The axial package style dictates the PCB layout requirements, necessitating adequate clearance for the leads and the molded body.
