  • Capacitor Engineering Bulletin: Polarization and Leakage Current Characterizations of High Voltage, Film Capacitors
    It is an unfortunate fact that "real" capacitors differ from ideal capacitors in many respects. Real capacitors include parasitic inductance and resistance, and vary in capacitance with temperature, frequency and voltage. This is especially true in high energy density capacitors, where dielectric
  • What is Capacitance?
    Physically, a capacitor is two electrical conductors separated by a non-conducting (or very high resistance) medium. between the conductors. Consider the two plates of area (A) in Figure 1. The plates are metallic and they are. separated by a distance (D). �� WHAT IS CAPACITANCE
  • Design Optimization Of Linear Transformer Driver (LTD) Stage Cell Capacitors (.pdf)
    Optimizing the design of Linear Transformer Driver (LTD) stage capacitors is important to achieve a very low inductance and short pulse output in pulsed power generators. The stage consists of many LTD capacitor. cells. The LTD performance is dependant on the characteristics of each capacitor
  • AN0006 Dielectric Ageing
    Capacitor ageing (Capacitance Drift) is a term used to describe the negative, logarithmic capacitance change that takes place in ceramic capacitors with time. The ageing process has a negligible affect on Class 1 (C0G) product but should be taken into account when measuring Class 2 (X7R, Y5V & Z5U

    and diminutive size require that component tolerances be tighter than those of many other products. A key factor in the safety of these devices is impedance, the opposition to ac current flow offered by a device or circuit. A complex value made up of resistance, inductance, and capacitance, impedance can help
