PTC Thermistors, Overload Protection for Telecommunication

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
