Thermistors
A thermistor is a type of resistor that changes resistance with temperature. It is often used in temperature sensing and control applications because of its high sensitivity and fast response time. Thermistors can be found in a variety of devices, including thermostats, automotive engines, and medical equipment. They are also used in industrial processes to monitor and control temperature. Flux.ai has the world's largest community-driven public library of thermistors, including footprints, symbols, datasheets, and simulation models. This extensive collection makes it easy for designers and engineers to find the right thermistor for their specific needs. Whether you are working on a small consumer device or a large industrial project, Flux.ai's library has the resources you need to get the job done.
10D-9
The 10D-9 is an NTC (Negative Temperature Coefficient) thermistor primarily used as an inrush current limiter in power supply circuits. It has a nominal resistance of 10 Ω at 25°C and a disk diameter of approximately 9 mm. When power is first applied, the thermistor's high resistance limits the surge current. As it heats up during normal operation, its resistance decreases significantly, allowing current to flow with minimal power loss. Key Features 10 Ω nominal resistance at 25°C. NTC characteristic – resistance decreases as temperature increases. Inrush current suppression for protecting power supplies and electronic equipment from startup current spikes. Low residual resistance after warm-up, minimizing power loss during normal operation. High reliability and long-term stability. Radial leaded package with epoxy/silicone-coated thermistor disk. Typical operating temperature range up to -40°C to +175°C (manufacturer-dependent). Typical Applications Switching Mode Power Supplies (SMPS) AC/DC adapters Battery chargers LED drivers UPS systems Motor drives and controllers Monitors, TVs, and PC power supplies Electronic ballasts and lighting equipment #CommonPartsLibrary #Thermistor
