Gowanda Electronics Launches New Non-Magnetic RF Inductor Series

September 16, 2021 by Hailey Stewart

Series Ideal for Medical Imaging and other Magnetic-Sensitive Applications.

Gowanda Electronics, a designer and manufacturer of high-performance inductors and magnetic components for demanding RF and power applications, announces the introduction of a new non-magnetic RF thru-hole (leaded) inductor series – 28MG. This series is ideal for use in medical imaging equipment and other applications where magnetic materials must be avoided.

These inductors will be featured at Gowanda’s booth #1054 during BIOMEDevice in Boston on September 21-22, 2021, and at booth #2235 during MD&M Midwest in Minneapolis on November 3-4, 2021. If you’re attending these shows please stop by Gowanda’s booth to learn more.

Gowanda’s 28MG series was designed to address the market need for non-magnetic inductors that could achieve inductance values of up to 18 µH for use in Magnetic Resonance Imaging (MRI) equipment, specific types of X-ray equipment, and other applications where the presence of magnetic materials could compromise system performance. This includes applications in telecommunications, security systems, instrumentation, laboratory analysis equipment, aviation equipment, navigation equipment, and electronic test equipment.

The performance range provided by the 60 discrete parts within the 28MG series includes Inductance from 1.2 µH to 18 µH, DCR Ohms from 0.079 to 4.15, and Current Rating mA DC from 315 to 2400. All of Gowanda’s non-magnetic surface mount and thru-hole inductors, including this new 28MG series, provide relative permeability of ≤ 1.00003.

The operating temperature range for the 28MG series is -55°C to +125°C. The 28MG inductors are epoxy encapsulated for environmental protection and superior strength to withstand all types of reflow soldering. Standard terminations are SnPb; RoHS-compliant terminations are provided when “LF” is specified. More technical information is available on 28MG at the company’s website including the 28MG Datasheet28MG Dimensional Specification, and other helpful information.

The table below provides an overview of the company’s MG (thru-hole, leaded) and SMG (surface mount) series; you can easily navigate to all the series via Gowanda’s Non-Magnetic Inductors website page.

Of note, Gowanda was the first inductor manufacturer to achieve the ISO 13485 quality standard, reinforcing its decades-long leadership position in providing inductive solutions to the medical electronics community. Gowanda was also the first global component manufacturer to introduce a truly non-magnetic inductor in the marketplace, leveraging proprietary technology and in-house expertise to provide medical sector customers with high performance solutions. Gowanda was also the first to introduce the world’s smallest non-magnetic surface mount inductor (SMG1812) which measures just 4.8 mm in length. Over the years, the expansion of the company’s magnetic and non-magnetic capabilities and inductor offerings in both standard and custom designs – now including the 28MG series – is a testament to Gowanda’s commitment to the global medical device industry.
