Michael Gurr ME304 Fall 2012

This research project, authored by Michael Gurr for ME304 in Fall 2012, delves into the characteristics of ceramic capacitors, the most widely used type of capacitor. These two-terminal, non-polar, passive devices utilize ceramic material as a dielectric, with the composition influencing dielectric properties. The study will focus on how temperature and sustained voltage impact capacitance, examining factors such as dissipation factor, dielectric withstanding voltage, and insulation resistance. Insights gained will contribute to understanding capacitance behavior in real-world applications.

  1. Oscillation Suppression Component Investigation: Capacitance AS a Function of Temperature and Voltage Michael Gurr ME304 Fall 2012

  2. Ceramic Capacitors • Most widely used type of capacitor • Two terminal, non-polar, passive device • Fixed capacitor with ceramic material serving as a dielectric • Composition of ceramic material determines dielectric properties • Have rated voltage and temperature ranges (i.e. tolerances)

  3. Capacitance • The ability of a body to store electric charge • With linear thermal expansion defined by • Factors in surface mount ceramic capacitance calculation include: • Dissipation factor • Dielectric withstanding voltage • Insulation/Heat resistance Project will focus on the effects of temperature and sustained voltage on capacitance
