FEATURES
• Wide resistance range in telecom area from 4 Ω
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 (up to 600 V)
• Good tracking over a wide temperature range for
all matched or binned thermistors (matching at
85 °C ≤ 2 x matching at 25 °C)
• UL1434 approved types available (XGPU2)
• All telecom PTCs are coated with a high temperature
silicon lacquer (UL 94 V-0) to protect them from any harsh
environments and to improve their lifetime
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
Over-temperature/over-load protection:
• Main distribution frame (MDF)
• Central office switching (C.O.)
• Subscriber terminal equipment (T.E.)
• Set-top box (S.B.)
