When/why (not) to use Tantalum capacitors. Pros, cons, alternatives A few weeks ago I worked through the Altium SMPS design course from FEDEVEL academy and that little project left me with an unresolved question. Somehow I got the idea in the past few years that tantalum capacitors are to be avoided, never really knowing why. […]
AVX Distributor Data: AVX tantalum capacitor Anode selection Switching power supply, a common trend of microprocessor and digital circuit is used to reduce the noise of high frequency at work. In order to do this, the components must have low ESR (resistivity), high capacitance and high reliability. AVX tantalum capacitor An anode for the overall surface area, especially the surface […]
Often overlooked in power supply, a stress is input capacitance ( KEMET tantalum capacitor RMS current). If you do not understand it correctly, a current will cause the capacitance ( KEMET tantalum capacitor Overheating and premature failure). In a buck converter, using the following approximation, the output current of the (Io) and duty cycle (D) can be calculated easily RMS: […]
The capacitor is two conductors sandwiched between an insulator elements, like hamburgers.Capacitor is one of the most basic and most important components in electronic equipment. The capacitance of the total global production of electronic components ( and its products SMD tantalum capacitors , resistor, inductor) in more than 40%. Basically all the electronic equipment, small flash disk, digital camera, […]
