Product Description
Product Overview
The MWI1812UC series is a range of wire-wound chip inductors designed for various electronic applications. These inductors offer a range of inductance values from 0.10 H to 27.00 H, with tight tolerances and specified quality factors (Q) and self-resonant frequencies (SRF). They are suitable for use in applications requiring reliable inductive components, with operating temperatures from -40 to +125 and compliance with Halogen Free (HF) environmental standards. The components are available in tape and reel packaging for automated assembly.
