Compac Development Corporation, established 1976, specializes in meeting your RFI/EMI shielded enclosure requirements.


Compac offers an extremely versatile line of off-the-shelf shielded enclosures plus the additional capability of customizing our standard product lines, manufacturing to your specs from prototype to production.


To further support the design function Compac offers a broad selection of RF accessories, gaskets, coaxial attenuators, coaxial terminations, filter feed-thrus, connectors, mounting bars, etc.


The Compac concept is geared to fast, accurate, dependable deliveries to meet the most demanding delivery schedules.




Compac has over 500 standard sizes that are truly "off the shelf" - from the "not so rf-tight" (our Blank series) to the "middle of the road" our RFT series to the "most rf-tight" (our SRF series) standard enclosure on the market.


Additionally, we have the ability to modify our standard products to your specifications. For example, we are able to provide connector patterns, tapped holes for feed-thrus, milling for D-Sub connectors, and punching for bulkhead mounted connectors per your needs. We are also able to lend each of the methods of manufacture to a custom size, manufacture that size and warrant the custom size's performance.




The standard finish on all of Compac's standard parts is Chemical Film per Mil-C-5541 Class 3. Compac offers a wide selection of other finishes from plated, such as Electro and Electroless Nickel Plating, Silver, Tin, Cad, Gold and Anodize. We also offer both paint and powder coating. We can part mark by silk screening, stenciling, engraving, or rubber-stamping.
