SSMB75 Series 75Ω SSMB Type Connectors ●SSMB75 series are connectors for 75 Ω group of SSMB series (50Ω group). ●DDK’s originally developed 75Ω group connec- tors are super mini-size push-on type. ●Strong against distortion by application of closed entry structure. ●Receptacles (L type for print base) are available, i.e., 1-5 rows. ●Not intermateable with SSMB series. ●Widely used for test instruments, broadcasting equipment, CATV and HDTV, etc. SPECIFICATION Characteristic Impedance 75Ω Dielectric withstanding voltage 500V AC (rms) for 1 minute Insulation resistance 1000MΩmin. at 500V DC Contact resistance 10mΩ max. VSWR 1.3max. at 1GHz Specifications depends on each connector although these are basic specifications. MATERIAL/FINISH Shell (Body) Copper alloy/Gold plating Contact (male) Copper alloy/Gold plating Contact (female) Copper alloy/Gold plating Insulators PTFE The performance may differ depending on the specification. ● 1 ● SSMB75 Series Unit : mm ■ Plug φ3.5 φ5.5 P/N SSMB75-SP-1.5CCA-EXBV Applicable Cable Hand Crimp Tool P/N 1.5CCA-EXBV CR-H-1101 Applicable Cable Hand Crimp Tool P/N （16.55） 9 φ5 □6 P/N 1.5C-QEW 14 SSMB75-LP-1.5CW-CR1 1.5C-2W φ4.7 ■ Receptacle 4- □ 0.6 P/N Mounting Hole SSMB75-SR-PC V 6.0 8.5 5.7 (12.8) 6.4 A C 3.55 φ2.65 5.7 8.2 2.5 7.62 0.6 φ0.65 2.54 2.54 0.6 5.7 P/N E D B A B C D E Mounting Hole 5.70 5.08 - - - V SSMB75-LR-PC-2 13.30 12.70 7.62 - - W SSMB75-LR-PC-3 20.92 20.32 15.24 - - X SSMB75-LR-PC-4 28.54 27.94 22.86 12.70 15.24 Y SSMB75-LR-PC-5 36.16 35.56 30.48 15.24 20.32 Z SSMB75-LR-PC ● 2 ● SSMB75 Series Unit : mm PCB Mounting Dimensions Mounting Hole V Mounting Hole W +0.1 2.54 ± 0.05 2.54 ± 0.05 5.08 ± 0.1 2.54 ± 0.05 5-φ1.2 -0 7.62 ± 0.05 2.54 ± 0.05 5.08 ± 0.1 (12.7) Mounting Hole X 2.54 ± 0.05 7.62 ± 0.05 7.62 ± 0.05 5.08 ± 0.1 2.54 ± 0.05 7-φ1.2 +0.1 -0 2.54 ± 0.05 (20.32) Mounting Hole Y 12.7 ± 0.15 2.54 ± 0.05 7.62 ± 0.05 7.62 ± 0.05 7.62 ± 0.05 5.08 ± 0.1 2.54 ± 0.05 10-φ1.2 +0.1 -0 2.54 ± 0.05 (27.94) Mounting Hole Z 15.24 ± 0.15 2.54 ± 0.05 7.62 ± 0.05 7.62 ± 0.05 7.62 ± 0.05 7.62 ± 0.05 (35.56) Pull-out Tool P/N:18M-SSMB75-11897 (Applicable SSMB75-LP-1.5CCA-EXBV) ● 3 ● 5.08 ± 0.1 2.54 ± 0.05 11-φ1.2 +0.1 -0 2.54 ± 0.05 5.08 ± 0.1 6-φ1.2 +0.2 -0 2.54 ± 0.05
