Fixed Inductors Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required 340 mA current rating and 550 mOhm DCR limits for the target application. Confirm RoHS compliance status prior to final procurement approval.

Fixed Inductors Selection Notes

Select this component when low parasitic capacitance and precise inductance values are critical for high-frequency operation. The thin-film process offers superior Q-factor consistency compared to thick-film alternatives. Consider the unshielded nature of the device to ensure adequate spacing on the PCB layout to prevent unwanted coupling with adjacent traces.
