(-40 to +90c) 4. the turnover temperature, t o , is the temperature of maximum (or turnover) frequency, f o . the nominal frequency at any case temperature, t c , may be calculated from: f = f o [1 - ftc (t o -t c ) 2 ]. 5. frequency aging is the change in fc with time and is specified at +65c or less. aging may exceed the specification for prolo nged temperatures above +65c. typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years. 6. the design, manufacturing process, and specifications of this device are subject to change without notice. 7. one or more of the following u.s. patents apply: 4,54,488, 4,616,197, and others pending. 8. all equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sa le. 9. tape and reel standard per ansi / eia 481. sm3838-8 case 3.8 x 3.8 pb
