YAGEO Negative Temperature Coefficient (NTC) Thermistors feature 5mm to 25mm diameter options, up to 150Ω resistance, and 0.25A to 22A current range. NTC protection components have resistances dependent on temperature, meaning they can be changed along with temperature to protect circuits. These thermistors have oxidized metal construction, are sensitive to current and temperature, and meet UL/TUV safety certifications. YAGEO NTC Thermistors are suitable for power supplies, PFC modules, transformers, and adaptors.
