Solid Al Electrolytics with Conductive Polymer or TCNQ Salt

C 3.5 SOLID AL ELECTROLYTICS with CONDUCTIVE POLYMER or TCNQ SALT C 3.5.1 Polymer electrolyte Other variant of a solid electrolyte is conductive polymer electrolyte. The aluminum oxide on an etched and formed foil is covered with an electrically very conductive and doped polymer as previously shown in Figure C3-7. ...

Solid Aluminum Electrolytics with Manganese Dioxide (obsolete)

C 3.4 SOLID ALUMINUM ELECTROLYTICS (SAL) with MANGANESE DIOXIDE (obsolete capacitor technology) The SAL are aluminum electrolytic capacitors with anodic oxidized aluminum oxide as dielectric and with the semiconducting solid manganese dioxide as electrolyte. They are made of etched and formed aluminum anodes, which are folded for the dipped pearl ...

Wet Aluminum Electrolytics

C 3.3 WET ALUMINUM ELECTROLYTICS C 3.3.1 Introduction Wet aluminum (Al) electrolytic capacitors continuously generate hydrogen gas under operation, even under a small residual charge. (note: if capacitors are stored voltage-free no hydrogen is being released during storage). That hydrogen must be able to diffuse and exit the package or ...

Concepts and Measurements

C 3.2 CONCEPTS AND MEASUREMENTS C 3.2.1 The CV product The product CR x VR is called the CV product and is a measure of the charge quantity. CR is expressed in µF and VR in volt. The product has the quantity µAs or µC (microCoulomb). C 3.2.2 Leakage current ...
