souriau 8FLT-8FT-8FST-8FD Description Applications MIL-C 38999 circular filter connectors are widely used in military and aeronautical applications. They are suitable for severe operating conditions. These connectors are based directly on standard specifications : They are intermeatable and interchangeable as to the mounting with standard connectors of the same series.

Note : * M filter is the most popular filter. If you require other filter types, indicate the maximum operating voltage, maximum capacitance and minimum attenuation required at various frequencies. * B filter is substancialy more expensive than other filters. 417 souriau 8FLT-8FT-8FST-8FD Contact layouts viewed from front face of male insulator shells size 8FLT/8FD 8FT/8FST 35 09 11 13 15 17 19 21 23 08 6 # 22 D 35 98 13 # 22 D 35 6 # 20 98 22 # 22 D 10 # 20 35 19 05 37 # 22 D 19 # 20 5 # 16 35 26 8 55 # 22 D 26 # 20 8 # 16 35 32 66 # 22 D 32 # 20 35 41 79 # 22 D 41 # 20 35 53 10 12 14 16 18 20 22 100 # 22 D 53 # 20 35 25 61 8FLT, 8FD, 8FST : Pin and soket layout 24 8FT : Pin layout only Other layout : consult factory 128 # 22 D 61 # 20 418
