Tantalum-Polymer Capacitors are an ideal option for high-reliability, miniature, low-profile, and low-ESR (equivalent series resistance) capacitors. They have become a popular choice for design engineers due to their unique physical properties and enhanced safety characteristics. The T550B256K100BH4251 is a highly reliable, miniature, low-ESR tantalum-polymer capacitor featuring a true MNPT case, a low ESR, and a maximum operating temperature of 85 degrees Celsius. It is designed for use in commercial and residential applications, as well as many industrial applications.

T550B256K100BH4251 is constructed using high-end tantalum powders and a polymer dielectric. This provides increased reliability and improved safety characteristics with respect to thermal or electrical breakdown. The true MNPT case provides additional shielding and protection from outside interference such as EMI and RFI. It also provides greater stability in high-temperature environments.

The T550B256K100BH4251 tantalum-polymer capacitor has an operating temperature rating of -55°C to + 85°C, voltage ratings from 6V to 50V, capacitance values from 0.01µF to 1µF, and ESR values from 0.004 to 0.1. Its low-profile design makes it suitable for applications where board space is limited, such as in portable electronics, handheld devices, and small board-level components.

The working principle of a tantalum-polymer capacitor is based on the movement of electrons. At one terminal, electrons are transferred to the other terminal through a layer of polymer dielectric material. The electrons move through the dielectric by hopping from one electron-energy shell to another. The movement of electrons creates a charge across the two terminals and produces an electric field. This electric field is what creates the capacitance of the device. The capacitance value of the device depends on the size and composition of the polymer dielectric material and the distance between the two terminals.

When operating, the T550B256K100BH4251 tantalum-polymer capacitor provides reliable performance with a low ESR value, a true MNPT case, and a high temperature rating. This makes it an ideal choice for many commercial and residential applications, as well as many industrial applications where board space is limited and high-reliability performance is desired. Its low-ESR design, enhanced safety characteristics, and miniature size make it an attractive option for design engineers.
