Custom Commercial Filters

Astrodyne designs cost-effective EMI filters and RFI filter solutions for project-specific applications for military, aerospace, commercial, industrial, medical and appliance industries. 

Our unrivaled 30+ years of expertise helps you get your product to market quickly, efficiently and with the least amount of internal hassle. We do it for you!


Astrodyne is dedicated to providing economically viable EMI & RFI filters and EMC solutions to satisfy your unique needs. To achieve this, we have two fully equipped in-house shielded facilities where EMC testing, EMI/RFI filter design and EMC solution development are accomplished.

We have experience with aerospace (RTCA/DO160) as well as commercial (FCC, CISPR, EN, VDE, AUSTEL, SABS, etc) test standards. We have been helping our customers achieve compliance with European Union EMC requirements (CE) since their inception. Astrodyne Electronics has over 18,000 different filter designs and in many circumstances, we can tailor these designs to meet the most demanding product requirements without costly and time consuming re-engineering.

Since EMC is our primary business, we can usually provide a solution for a custom- designed EMI application within five days. We provide high quality, cost-effective and unique EMC solutions, as well as quick turn-around times — typically, we’ll supply custom prototypes within one week, and production quantities in four weeks.

If we are involved early on in your product design cycle, we also can offer you expert customers consulting services, application engineering, and assistance in selecting components that are EMC friendly. At our agency approved “in-house” test facility, US, Canadian and/or European safety approvals can be obtained quickly and cost effectively on any of our customized and custom product, if needed. For more information on our custom filter capabilities, contact us today!
