MIL-C-24308, Extended Shell 162 All extended shell connectors are manufactured by adding filters to a standard MIL qualified connector. The filtering is achieved by extending the connector with the use of a backshell and placing either planar or tubular capacitors in the backshell. Spectrum will always keep the extension to a minimum. Custom Designs This part of the catalog is very custom in nature. If you do not see what you require for your applica- tion, contact the factory as we will be able to satisfy your needs. Materials and Finishes Front shell.....
