Gowanda has a Magnetic Attraction to Industry Firsts


By Denis Kolhagen, VP of Sales, Gowanda Components Group U


ntil now, off-the-shelf, high-reliability ER (Established Reliability) inductors for RF applications in the military have only been


available in through-hole configurations. Gowanda Electronics, a manufacturer of board-level magnet- ics, has changed this with the introduction of the first-ever SMT ER inductor series, ER3013. For many years, Gowanda has been designing


and manufacturing RF and power inductors, both through-hole and SMT, for the military’s Qualified Products List (QPL). That experience, combined


devices, and are used in communication, guid- ance, security, radar, test and evaluation, and specialty devices. “This development from Gowanda not only


breaks new ground, but also helps to assure design engineers that their next generation designs will have the necessary components, since Gowanda plans to introduce more ER SMT designs in the future,” says Don McElheny, CEO of Gowanda Components Group. The ER3013 series meets the military’s QPL requirements for ER to failure rate level M and addresses three MIL- PRF-39010 slash numbers (/19, /20 and /21). This qualification required extensive testing for electrical, envi- ronmental, mechanical, and thermal performance.


Industry Firsts This ER SMT development, and


many other firsts that have preceded it, have solidified Gowanda’s position in the magnetics industry. The com- pany’s success with space, flight and hi-rel solutions is the result of lever- aging technology, know-how and processes that meet the require- ments of demanding applications in these fields. The company’s MLRF0603 and


Gowanda’s ER3013 series ER SMT inductors.


with several successful ER through-hole qualifica- tions, has set the stage for the development of the ER3013 SMT inductors. The development of the inductor was also


enhanced by the company’s technical expertise and long-term relationships with OEMs, including gov- ernment contractors and the Defense Depart - ment’s Defense Logistics Agency (DLA).


ER SMT Inductors The military is attracted to surface mount


configurations since they can be used in high-effi- ciency pick-and-place circuit board assembly processes, especially when compared with labori- ous, multi-step through-hole assembly methods. The introduction of Gowanda’s ER SMT series will enable faster assembly and processing, helping to reduce the cost of high-reliability electronic sys- tems that require ER components. Applications for the wirewound, molded ER3013 series span military, aerospace and space


MLRF0805 series of RF surface mount wirewound ceramic core chip inductors were introduced to address a need for components to meet the Department of Defense MIL-PRF-


83446 specification (/36A and /37A). Gowanda was also the first company to introduce these two sizes of QPL gold-terminated RF chip inductors to meet particular military specs. Following these inductors, the company was


the first in the industry to offer tin/lead terminat- ed versions of the 0603 and 0805 RF chip inductors for military applications. The Sn/Pb series were designed to provide an effective, time-saving and solder-friendly solution for component assembly processes, compared to the multi-step methods required for gold terminations. The company was also first to achieve the


highest level of qualification for military spec (Level T) on three MIL-PRF-27 slash sheet surface mount power inductor series. Gowanda’s MLP5025-T, MLP1812-T and MLP8527-T induc- tors were first to achieve Level T and were added to the military’s Defense Logistics Agency Land and Maritime Qualified Products List. There are firsts for other industries too.


Gowanda was first to introduce the world’s small- est non-magnetic molded RF inductors for medical applications, including medical imaging and other magnetic-sensitive applications. The company’s SMG1812 surface mount wirewound series was introduced with overall dimensions 40 percent smaller than the industry’s previously smallest non-magnetic RF inductor series, which was also created by Gowanda. The SMG1812 was designed specifically for


applications that are magnetically sensitive and therefore require non-magnetic components. Relevant applications include test equipment and medical diagnostic equipment — specifically, imag- ing equipment for MRI (magnetic resonance imag- ing) and particular types of X-ray equipment.


Strategic Acquisitions To expand its product portfolio of solutions


and firsts for the passives industry, Gowanda’s parent company, Gowanda Components Group, has pursued strategic partnerships and acquisi- tions over the last five years. On the magnetics side of the business, these acquisitions include Communication Coil, Butler Winding, and most recently, Dyco Electronics. On the filters side of GCG, the companies acquired include Instec Filters, TTE Filters and Microwave Circuits.


MLP power inductors that meet MIL-PRF-27, Level T.


All of these acquisitions were pursued in


order to enable GCG to accelerate its plans for growth in strategically important products and markets through its technology, design, manufac- turing, sales channels and customer synergies. The company looks forward to expanding its line of passive components to address the needs of the
