B82789S0: Suppression of asymmetrical (by L ) and symmetrical interference (by L ) R stray coupled in on lines. The high-frequency portions of the symmetrical data signal are decreased so far that EMC problems can be significantly reduced. Applications Automotive applications, e.g. CAN and FlexRay bus Industrial field bus systems Line cards for telecom Terminals Tinned terminals (B82789C0/S0*002) Base material CuSn6 1) Layer composition Ni, Ag, Sn Lead-free tinned Gold-plated terminals (B82789C0/S0*001) Base material CuSn6 Layer composition Ni, Ag, Au Gold plated 1) Ni-barrier-plated terminals (NiSn) on request (B82789C0/S0*H052).
