Product Description
Product Overview
Littelfuse low-cost, interchangeable glass-encapsulated thermistors are manufactured using highly stable, precision NTC chips hermetically sealed in a glass (DO-35 diode style) package. This construction ensures excellent long-term reliability and stability, even under severe environmental or thermal conditions. Their interchangeability eliminates the need for costly individual circuit calibration, and their uniform dimensions with axial lead configuration make them ideal for automatic insertion equipment.
