Gowanda Intros Smallest Non-Magnetic Inductor
World's smallest non-magnetic molded RF inductor.
Gowanda, NY — Gowanda Electronics has introduced the world's smallest non-magnetic molded RF inductor series, SMG1812. This new surface mount wirewound series measures just 4.8 x 3.4 x 3.5mm (height) — more than 40 percent smaller than the company's SMG3013 series, which had been the industry's smallest non-magnetic molded RF inductor series until now. The development of smaller inductor designs is in response to the ongoing market trend for smaller devices and therefore smaller components.

The SMG1812 was designed specifically for applications that are magnetically sensitive and therefore require non-magnetic components. Relevant applications include test equipment and devices and medical diagnostic equipment — specifically imaging equipment such as MRI (magnetic resonance imaging) and particular types of X-ray equipment.

Technical specifications include inductance from 0.010 to 0.082µH, Q min from 35 to 40, SRF Min from 750 to 1000MHz, DCR Max from 0.1 to 0.25Ω, and current rating DC from 700 to 1230mA. A RoHS-compliant lead-free version is available and is denoted SMG1812LF.

It is anticipated that these new components will be used not only in the medical industry but also in a wide variety of market applications and industries where magnetic materials and magnetic characteristics must be avoided. These other applications could include use in telecommunications, security systems, instrumentation, laboratory analysis equipment, aviation equipment, navigation equipment and electronic test equipment.

The new product series expands the company's non-magnetic "MG" inductor product line. Inductors manufactured using traditional methods can exhibit magnetic characteristics that are undesirable in certain applications. This new part and the other components in the MG product line are manufactured using a proprietary company-developed methodology that assures the inductors have non-magnetic characteristics.

Other RF inductor products include additional surface mount versions and through-hole leaded designs. Technical specifications for these other non-magnetic series include: Inductance options from 0.01 to 4.7µH, DCR Max from 0.08 to 2.6Ω, and current ratings DC from 260 to 3835mA. RoHS-compliant versions are also available.
