The QN0402X103J3435HA with NTC Thermistors 0402 RoHS is a negative temperature coefficient (NTC) thermistor manufactured by QAMcn. It is a chip with an embedded NTC thermistor in a plastic package. It has a resistance of 10K ohms at 25°C, and its resistance decreases as temperature increases. The thermistor is RoHS (Restriction of Hazardous Substances) compliant, meaning it complies with European legislation to reduce the amount of hazardous materials used in the manufacturing process. It is a miniature size, measuring only 0.04 x 0.02 inches (1.0 x 0.5mm). It has a rated power of 100mW, a temperature coefficient of -3,435%/K, and a tolerance of ±1%. In addition, it has an operating temperature of -55 to 150°C and a static capacitance of 1,000pF.
