The NTC Series resistors are designed to provide accurate temperature sensing and control in various electronic applications. They exhibit a negative temperature coefficient, meaning their resistance decreases as temperature increases. This characteristic makes them ideal for inrush current limiting, temperature compensation, and temperature measurement.
