T491B475M020ZTAU50

T491B475M020ZTAU50 are a type of tantalum capacitors, which are electronic components with a special construction making them suited for specific situations. Tantalum capacitors have been used in the electronics industry since the 1940s, and their popularity has only grown since then. Tantalum capacitors offer advantages such as their extremely small physical size, significantly higher capacitance compared to their physical size, and high voltage ratings. The primary applications of these capacitors are as filters and decoupler capacitors in power supplies, as output capacitors in oscillators, and as bypass capacitors in audio and RF circuits.

T491B475M020ZTAU50 have a Molded Case tantalum capacitor construction. This construction begins with two sintered tantalum anodes separated by a dielectric layer and capped with a metalized layer. A special electrolyte is placed in the case to complete the construction. This basic construction allows for various lead styles and termination options, as well as various case sizes and shapes, which makes the T491B475M020ZTAU50 ideal for many applications.

The primary feature of the T491B475M020ZTAU50 is its low Equivalent Series Resistance (ESR). A tantalum capacitor with low ESR is especially suited to high frequency applications, since the ESR of a capacitor has a significant effect on its ability to handle a high frequency signal, with a lower ESR typically resulting in less distortion, playing a key part in the performance of any high frequency circuit.

The working principle behind the T491B475M020ZTAU50 is similar to that of other types of capacitors. A voltage applied across the capacitor creates an electric field between the two metal plates, causing electrons to be displaced. This displacement creates a charge that is stored on the capacitor’s plates, effectively functioning as a temporary power source. As the voltage applied across the capacitor decreases, the charge is slowly released, supplying the necessary power for the circuit or device to operate properly.

T491B475M020ZTAU50 can be used in a variety of applications, from power supplies and filters, to oscillators and RF circuits. They are especially well-suited for high frequency and high voltage applications where their low ESR and high capacitance make them the technology of choice. Additionally, due to the various lead styles, case sizes, and termination options available, the T491B475M020ZTAU50 are one of the most versatile tantalum capacitor technologies available today.
