* Outline: A combination of ceramic craftsmanship with semi-conductor craftsmanship is adopted for manufacturing products of this model. Products of this model are glass-packed with axial lead at both ends. * Application： 1. For Temperature testing and control in domestic appliances such as air-conditioners, micro-wave ovens, electric fans, and electric heaters. 2. Temperature testing or temperature compensation in automatic office facilities such as copiers and printers. 3. Temperature control and testing in facilities concerning industry, health-care, environment protection, weather forecasting and food processing. 4. Liquid level indicating and flow measuring. 5. Cells for mobile telephones. 6. Temperature compensation to coils for meters, integrated circuits, quartz crystal oscillators and thermocouples. *Features： 1. High stability and reliability. Wide range of resistance value from 0.1 to 1000k 2. High precision of resistance value. 3. Usable even under high-temperature and high-humidity environment owing to its glass encapsulation. 4. So small, light and solid in structure as to be convenient for auto mounting (to a printed circuit board). 5. Response quickly to and highly sensitive to thermal sensation. *Specification： 1. range of resistance ratings at Zero-wattage(R25):0.1~1000kΩ 2. Tolorance of R25:?%,?%,?%,?%,?0%. 3.
