Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'F' confirms the required ±1% tolerance level against project specifications. Ensure the 1008 package dimensions align with the designated footprint on the printed circuit board. Confirm that the 380 mA current rating satisfies the operational requirements of the target application without saturation. Check RoHS compliance status if environmental regulations apply to the manufacturing process.

Fixed Inductors Selection Notes

Select this component when precise inductance values are critical for RF circuit stability. The unshielded design requires careful layout consideration to minimize electromagnetic interference with adjacent traces. Evaluate the thermal environment to ensure operation remains within the specified -55°C to +125°C range. Consider the physical size constraints of the 1008 package relative to available board space.

Fixed Inductors Part Context

This part belongs to the Murata LQW2UA series of fixed RF inductors. The series offers various inductance values and tolerances within the same form factor.
