Tantalum CapacitorsTantalum capacitors are a kind of capacitor used in various electronic equipment. It is mainly used in power supplies, signal tuning and filtering circuits. TAJS226K004RNJ is one of the tantalum capacitors available on the market. This article will elaborate on its application field and working principle. Application FieldTAJS226K004RNJ is mainly used in electronic equipment that requires low volumetric efficiency and high capacitance in a small form factor. It is used in consumer-grade television sets, power supplies, automotive electronics, and military communications equipment. It can also be used in the filtering of audio signals in mobile phones, bluetooth headsets, and speakers.Working PrincipleA TAJS226K004RNJ capacitor works on the principle of electrostatic charge separation. This means that when the capacitor is connected to a voltage source, one of its leads will accumulate positive charge while the other will accumulate negative charge. When a voltage is applied across the leads, the accumulated charges will cause an electric field to be generated between the two leads. This electric field is known as a capacitor.The TAJS226K004RNJ has a dielectric oxide layer of tantalum pentoxide between its two electrodes. This oxide layer functions as an insulator, and thus it prevents current from flowing through the capacitor. When an electric field is applied on the oxide layer, the field lines will be bent due to the polarization effect of the layer. This allows for a greater amount of charge to be stored in the capacitor due to increased capacitance. The total capacitance value of the capacitor is determined by the size and thickness of the oxide layer. ConclusionThe TAJS226K004RNJ is a kind of tantalum capacitor that is mainly used in various types of electronic equipment. It utilizes a dielectric oxide layer of tantalum pentoxide to increase its capacitance value. This allows it to be used in applications where low volumetric efficiency and high capacitance are required in a small form factor.
