Product Attributes

Introduction

These directly heated ceramic-based thermistors have a positive temperature coefficient and are primarily intended for overload protection. They consist of a ceramic pellet soldered between two tinned CCS wires and coated with a UL 94 V-0 high temperature hard silicone lacquer. Bare metalized pellets are available on request.

Features

• Wide range of trip and non-trip currents: From 94 mA up to 2 A for the trip current
• Small ratio between trip and non-trip currents (It/Int = 1.5 at 25 ℃)
• High maximum overload current (up to 23 A)
• Leaded parts withstand mechanical stresses and vibration
• UL file E148885 according to XGPU standard UL1434
• Material categorization: for definitions of compliance please see www.vishay.com/doc?99912

Applications

• Overload (current, voltage, temperature) protection in:
• Industrial electronics
• Consumer electronics
• Electronic data processing
