S Series resistance, due to contacts (leads, sprayed metal and film metallization) R P Parallel resistance, due to insulation resistance C Capacitance C, R S and L S are magnitudes that vary in the frequency domain (AC). R P is a magnitude defined in DC (insulation resistance). 2.2 Capacitance 2.2.1 Rated capacitance / measuring conditions
Structure of anode foil for low-voltage capacitors (magnification 400x) The dielectric layer of an aluminum electrolytic capacitor is created by anodic oxidation (forming) to build up an aluminum oxide layer on the foil. The layer thickness increases in proportion to the

EPCOS thermistors are designed for specific applications and should not be used for purposes not identified in our specifications, application notes and data books unless otherwise agreed with EPCOS during the design-in-phase. Ensure suitability of thermistor through reliability testing during the design-in phase. The ther-

Electronics is the processing of electrical charges as information. Nam June Paik, one of the pioneers of the field of electronic art, makes this distinction very clear by commenting on "electricity" and "electronics": "Electricity deals with mass and weight; electronics deals with information: one is muscle, the other is nerve." (from: Gene
