摘要:
PURPOSE: A temperature-compensating thin-film capacitor is provided to realize smaller, thinner, and lighter capacitor and to have a function of temperature compensation by using dielectric materials which have a low specific inductive capacity and of which temperature dependence is controllable. CONSTITUTION: The temperature-compensating thin-film capacitor(1) includes a first dielectric thin-film(5) having a specific inductive capacity of 4.0 or less and a linear thermal expansion coefficient of 50ppm/°C or more, and includes a second dielectric thin-film(4) having capacitance-temperature coefficient with an absolute value of 50 ppm/°C or less, in which the first and the second dielectric thin-films are placed between electrodes. Difference in capacitance of such a thin-film capacitor is reduced, in which the difference is due to processing accuracy.
