36、acts). These have no characteristic impedance and are therefore not recommended for use at high frequency. Type E: Removable contact with screening feature, including coaxial, triaxial, bifilar and quadrax contacts. These have matched impedance. NOTE Type B contacts are defined in the connector spec

37、ifications. 4.2 Temperature classes The contacts specified shall be from one of the classes specified below: class P: maximum operating temperature 125 C; class R: maximum operating temperature 150 C; class S: maximum operating temperature 200 C; class T: maximum operating temperature 260 C; class U
