Amphenol Advanced Sensor/Thermometrics YQS5749PTO PTC Disc Thermistor

The Amphenol Advanced Sensor/Thermometrics YQS5749PTO series thermistors are radially-wire bare PTC disc thermistors designed for a variety of applications. These thermistors offer a low-cost, solid-state sensing solution with a broad range of resistances, transition temperatures, and voltage ratings. Their resistance increases significantly with temperature, making them ideal for current regulation, circuit protection, and temperature measurement and control. The repeatable resistance/temperature characteristic and lack of hysteresis ensure reliable performance over time. They are constructed with a bare ceramic disc, thick silver film electrodes, and tin-coated copper wire terminations.
