FEATURES PRIMARY PROTECTION (OPTIONAL) +θ PTC subscriber lines +θ SECONDARY PROTECTION +θ PTC voltage clamp +θ PTC MDF SUBSCRIBER LOOP INTERFACE CIRCUIT (SLIC) OR TRANSFORMER - - - - - - - - CCB913 Typical telephone line showing where PTC thermistors can be used for overcurrent protection. Wide resistance range in tele area 4... to 70 Ω Fast protection against power contact faults Withstand high overload currents of up to 10 A High voltage withstanding capabilities for the larger sized thermistors Good tracking over a wide temperature range for all matched or binned types UL1434 approved types available (XGPU2) Excellent stability over extended time All tele PTCs are coated with a high temperature silicon lacquer (UL94V0) to protect them from any harsh environments and to improve their lifetime. APPLICATIONS - - - - Main Distribution Frame (MDF) Central Office Switching (C.O.) Subscriber Terminal Equipment (T.E.) Set-top box (S.B.). DESCRIPTION Advanced developments in telephony equipment in recent years have radically altered the protection requirements for both exchange and subscriber equipment. The Vishay BCponents range of Positive Temperature Coefficient (PTC) thermistors includes devices specially designed to provide overcurrent protection. MARKING Clear marking on a grey coated body.
