Electrode electrode. In a vacuum tube or a semiconductor having polarity (diodes, electrolytic capacitors) the anode is the positive (+) electrode and the cathode the negative (−). The electrons enter the device through the cathode and exit the device through the anode. Many devices have other electrodes to control operation, e.g., base, gate, control grid. In a three-electrode cell, a counter electrode, also called an auxiliary electrode, is used only to make a connection to the electrolyte so that a current can be applied to the working electrode. The counter electrode is usually made of an inert material, such as a
SAL electrolytic capacitor loads have a much higher reliability with respect to tantalum electrolytic capacitors. In addition, the dielectric aluminum oxide in combination with the electrolyte manganese dioxide has a relatively high voltage resistance against wrong polarity. SAL electrolytic capacitors are used for filtering, smoothing coupling and decoupling applications in industrial, medical and automotive equipment. The axial style of SAL capacitors has military and high professional applications up to 200 °C. Compared to non-solid electrolytic capacitors, SAL capacitors Compared to polymer electrolytic capacitors, SAL capacitors The standardization for all electrical, electronic components and related technologies follows the rules given by the International Electrotechnical
