Gowanda, NY — Gowanda Electron - ics has introduced the world’s small- est non-magnetic molded RF induc- tor series, SMG1812. This new sur- face mount wirewound series meas- ures 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 small-

trend for smaller devices and there- fore 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

Chemtronics Intros Fast Dry Conformal Coating
Kennesaw, GA — Chemtronics has introduced Konform® Ultra which reportedly provides superior drying speed and electric insulation. Ultra fast-drying acrylic conformal coating is formulated to provide maximum process throughput, while maximiz- ing insulation protection against high-voltage arcing and corona shorts. It quickly dries to the touch, allowing for fast production turn- around.
The new material provides a
hard, durable protective barrier against humidity, salt, corrosive vapors and fungus for printed circuit board and electronic assemblies.
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 0.25W, 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 mate- rials and magnetic characteristics must be avoided. These other appli- cations could include use in telecom- munications, security systems, instrumentation, laboratory analysis equipment, aviation equipment, nav- igation equipment and electronic test equipment. The new product series expands
the company’s non-magnetic “MG” inductor product line. Inductors man- ufactured using traditional methods can exhibit magnetic characteristics that are undesirable in certain appli- cations. 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-mag- netic 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 2.6W, and current ratings DC from 260 to 3835mA. RoHS-compliant ver-
sions are also available. Contact: Gowanda Electronics,

Conformal coating provides PCB protection.
This coating meets IPC-CC-
830B Class B and sections of MIL-I- 46058C, type AR. It contains a UV indicator for quality control inspec- tion. It is compliant with European RoHS and REACH directives in addition to most other environmen- tal standards. The conformal coatings provide
excellent electrical insulation and withstand hot and cold operating environments, as well as heat gener-
ated by electronic circuitry. Contact: ITW Chemtronics,
