Fixed Inductors Procurement Notes

Verify the specific tolerance suffix when ordering, as the base model may support various codes. Confirm that the 2 MHz self-resonant frequency aligns with the target application's operating bandwidth. Ensure the 300 mA current rating meets circuit requirements to prevent saturation or thermal issues during operation.

Fixed Inductors Selection Notes

Select this component for compact 0402 footprint designs requiring precise 43 nH inductance. Consider the low Q factor relative to higher frequencies due to the 2 MHz SRF limit. Evaluate the 0.5 Ω DC resistance impact on power efficiency if used in high-current paths compared to lower-resistance alternatives.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies.
