Previous set of Capacitor Terms and Definitions
Paper: A type of dielectric. Paper Capacitors are used in High voltage applications. Paper devices should not be used in a high moisture environment unless the device is in a hermetic case, the capacitance will increase, the power factor - insulation resistance - dielectric strength - and life will degrade. Paper capacitors have near 10% tolerances.
Plastic Film: A type of dielectric. Plastic film capacitors have all the attributes of a paper diealectric but do not operate to as high a voltage. There are seven types of Plastic Film dielectrics; Mylar, Polycarbonate, Polyester, Polypropylene, Polysulfone, Polystyrene, Teflon. Manufacturers of Plastic Film Capacitors
Partially inactive for new design: Containing both active and inactive Department of Defense specification sheets (for Department of Defense specifications), or both active and inactive parts (for Department of Defense specification sheets).
Polarized Capacitor: An electrolytic capacitor with the dielectric film adjacent to only one metal electrode. Polarized Capacitors are designed to operate with only one direction of current flow, reverse current flow in the opposite direction will damage the part. The anode is the plus, and the cathode is negative. With leaded devices the cathode lead is shorter than the anode. Surface mount caps will have a polarity band on the anode. Normally found as the higher capacitance devices. Polarized Capacitor Manufacturers.
Power factor (PF): The ratio of resistance to impedance, measured in percent.
Pulse Capacitor: A capacitor developed for extremely high pulse loads.
