RF Inductors Are Not Magnetic

These miniature inductors are designed for applications where magnetism must be kept to a minimum, such as in medical x-ray machines

The SMG1812 RF inductor series is touted by its manufacturer, Gowanda Electronics, as featuring the world’s smallest nonmagnetic RF inductor. The wire-wound, surface-mount inductors are 40% smaller than the company’s previous smallest non-magnetic molded RF inductors, the SMG3013 series. They are designed for magnetically sensitive applications, such as test equipment and medical diagnostic equipment. The miniature SMG1812 inductors measure just 4.8 x 3.4 x 3.5 mm. The components are available with inductance values of 0.010 to 0.082 μH, minimum quality factors (Qs) of 35 to 40, minimum self-resonant frequencies (SRFs) from 750 to 1000 MHz, maximum DC resistance (DCR) values of 0.10 to 0.25 Ω, and DC current ratings from 700 to 1230 mA. A lead-free RoHS-compliant version is available as model SMG1812LF.
