Product Attributes

Introduction

These directly heated ceramic-based doped barium titanate thermistors have a positive temperature coefficient and are primarily intended for inrush current limiting and overload protection. They consist of a ceramic pellet soldered between two tinned CCS wires and coated with a UL 94 V-0 compliant high temperature silicone lacquer. The body is marked with the logo, cold resistance value, EL on one side and date code on the opposite side.

Features

• High energy absorption levels up to 150 J and 240 J
• High number of inrush-power cycles: e3 > 100 000 cycles
• Highly resistant against non-switching peak-powers of up to 25 kW
• Can handle high direct voltage up to 1200 V
• Self protecting in case of overload with no risk of over-heating
• AEC-Q200 qualified
• c-UL-us recognized under file E148885 for AC and DC use
• Material categorization: for definitions of compliance please see www.vishay.com/doc?99912

Applications

• Inrush current limiting and load-dump resistor in AC/DC and DC/DC converters
