About Captor Corporation

Captor Corporation Company History

Captor Corporation was established in 1965 by an engineering oriented management team. This team brought several experienced veterans with them which provided a solid foundation for the company. This core group possessed an exceptional depth of experience in the electronic filter industry and related field of military and aerospace communications.

Early success enabled the company to build a dedicated manufacturing facility shortly after inception. This building has been expanded several times to its present 35,000 square foot, state of the art facility, which houses all aspects of our business including engineering, sales, and production.

The company has seen steady growth over the past forty plus years. Captor has built its reputation as an industry leader by providing outstanding engineering solutions, customer service, and reliable products to our customers at a fair price. We truly understand that listening to our customers and providing exactly what they ask for, is key to our success as well as theirs. Building partnerships with our customers is of paramount importance to us.

We are the leader in the field of custom EMI filters. Our custom solutions usually can be delivered faster and at a more competitive cost than many of our competitors so called “off the shelf” or COTS parts. In addition, we are able to tailor these solutions to meet your exact requirements without added cost. Don’t let the word “custom” scare you, it may just be the best solution.

This website will showcase our products and capabilities. We do not expect that you will find the exact solution within these pages. However, the intent is to give prospective customers an idea of our extensive products and diverse capabilities. Please give us a call to discuss your exact requirements and give us the opportunity to design a solution that exceeds your expectations.

Captor Corporation Assembly & Design

Standard and custom-built capacitor winding equipment gives the engineers at Captor Corporation the advantage of almost limitless design capabilities. Values, sizes, and ratings are determined upon the application and capacitors are designed for reliability in a compact package.

We offer standard capacitor brochures, but you are not limited by what you see. We can design your specific capacitor application in the configuration you desire.

Captor inventories a vast array of capacitor films and foils. This allows us to custom wind almost any capacitor configuration.

The equipment and knowledge we have attained over 45 years of making the highest quality EMI filters has helped us build our contract manufacturing business to a reliable solution for low to medium-volume jobs. From reverse engineering circuit boards to brand new designs, Captor will see your project through to completion.

Captor designers and engineers use the latest software to concisely layout products. When necessary, detailed drawings are generated to provide clear and concise assembly instructions. 3D Cad, 2D Cad, PCAD, and other software programs are used to provide such direction.

An advanced shielded room with an all-welded design offers dependable pre-compliance testing to applicable specifications. Captor engineers can also test products that are failing a specific test parameter and design a filter that will eliminate the noise causing the failure.
