Vishay SST113 is a sensing element used to measure the temperature of a sensor. It is a thermistor featuring a nickel-plated copper leaded construction and measures temperature using the thermistor principle. It is available in three types that differ in the type of thermistor material used. The SST113 series is made from a positive temperature coefficient (PTC) material that behaves like a resistor but changes its resistance with the change in temperature. This makes it ideal for use in temperature measurement applications. It also features a low self-heating design, which makes it very accurate in measuring temperature. It is often used in consumer and industrial electronics as it is highly reliable and cost effective.
