Tantalum - Polymer Capacitors are a type of capacitor, a type of electrical component used for storing energy in an electric field. The M551B128K050AT is a solid polarization tantalum-polymer capacitor, also known as a polymer-tantalum hybrid, constituted of a dielectric made of organic materials and an anode made of sintered tantalum. It is a very high energy density capacitor of the SMD family, specifically designed for the most demanding applications.

The M551B128K050AT capacitor offers great performance and high charge/discharge efficiency, in part due to its low Equivalent Series Resistance (ESR) and its ability to maintain stable electrical characteristics even when operating at high frequencies. It has a capacitance value of 128µF, a 0.5Ω ESR, a voltage rating of 16V and an operating temperature range of -55℃ to +85℃.

This capacitor finds its application in several electronics systems, such as portable electronic devices and automotive electronics, as well as audio and digital equipment. Due to its high stability and long lasting reliability, the M551B128K050AT is popular in medical equipment, and is used in EMC circuit designs in consumer electronics.

The polymer-tantalum hybrid technology of the M551B128K050AT capacitor allows for an extremely compact design, proving useful in space-restricted applications. The compactness comes due to the synergetic effect of merging two separate materials. The dielectric of the M551B128K050AT is a nearly pure polymer by volume, but when combined with the anode made of sintered tantalum, provides a very large output energy. The high energy capability of the M551B128K050AT proves indispensable in applications involving microprocessors, where multiple capacitors must be placed in parallel.

The working principle of the M551B128K050AT capacitor is based on the electrostatic phenomenon. Through its three terminals, the capacitor produces an electric field between the anode and the cathode by collecting the free charges carried by an electrolytic solution or a solid insulation medium. When a charge is applied to the terminals of the M551B128K050AT, an electric field proportional to the applied voltage is created around the conductor, thus allowing the capacitor to store energy.

The M551B128K050AT is a robust and reliable capacitor that can efficiently store energy in high frequencies due to the polymer-tantalum hybrid technology. Its flexibility, compactness and high efficiency makes it a popular choice in portable and automotive electronics, as well as digital equipment and medical equipment. Its performances are all the more remarkable given its low size and volume.
