Engineered with a hermetically sealed glass body measuring a maximum 0.020 inches in diameter, this rugged thermistor features a standard resistance of 10,000 Ohms at 25°C with a 10% tolerance, mapped to RT Curve 16. The component incorporates tinned copper-clad steel leads that support both soldering and welding processes, ensuring reliable mechanical and electrical integration into printed circuit assemblies. Built for high-reliability environments, the DO-35 style glass encapsulation provides exceptional resistance to harsh chemical and thermal conditions, supporting an extensive operating temperature range from -60°C up to +300°C. The device exhibits a dissipation factor of 2.5 mW/°C minimum and a thermal time constant of 4 seconds maximum in still air. Its uniform physical dimensions and compatibility with automated tape and reel assembly make it well-suited for high-volume manufacturing lines requiring robust thermal management sensors. This NTC thermistor is typically deployed in temperature compensation circuits, HVAC systems, industrial process controls, and consumer appliances where precise thermal tracking is critical. The compliant material construction is free of restricted substances, meeting current environmental regulations including SVHC compliance standards as of June 2025. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (25-Jun-2025) | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4776229/) 1 N C O© R P @O@ RF AT E DO Je resesupetscrgonics ! ## NTC THERMISTORS **==> picture [506 x 216] intentionally omitted <==** **----- Start of picture text -----**
