Tantalum-polymer capacitors are polarized capacitors that feature a tantalum anode, an organometallic electrolyte, and a porous organic cathode. They are commonly used in such applications as decoupling or bypassing circuits, filtering, and power supply noise attenuation. The T550B256M100BH42520100 tantalum-polymer capacitor utilizes these characteristics to meet the high power demands of many electronic applications.

Tantalum-polymer capacitors are characterized by a wide range of capacitances, often ranging from 4.7 microfarads to over 330 mF in surface mount format. This wide range of capacitances can meet the needs of most applications, including bypass and decoupling as well as power supply transient immunity. The T550B256M100BH42520100 offers a high capacitance value of 100 mF and a temperature range of -55°C to +105°C. This makes it ideal for use in ambient temperature applications.

Tantalum-polymer capacitors are also significantly smaller than equivalent electrolytic capacitors and can be used in applications where space is at a premium. The T550B256M100BH42520100, for example, is a standard 7 mm x 5 mm surface mount component, making it a perfect choice for high-density applications. Additionally, these components are extremely reliable, with a high ripple current capability and an operating life of up to 30,000 hours.

The T550B256M100BH42520100 tantalum-polymer capacitor is well suited to a variety of applications, owing to its high capacitance, temperature range, and form factor. These components are designed for use in a variety of applications, including power supplies, DC-DC converters, automotive, and industrial equipment. It is also ideal for use in portable electronics, such as cellphones and tablets.

The working principle of a tantalum-polymer capacitor is relatively simple. The anode of the capacitor is made of a sintered tantalum powder, which is then soaked in a conducting electrolyte. A positive voltage is applied to this anode, which causes an electrochemical reaction which forms an oxide layer on the anode. The oxide layer acts as a dielectric, allowing the capacitor to store an electrical charge.

The cathode of the capacitor is made of a porous organic material which is also soaked in the same electrolyte. When the capacitor is under a positive voltage, the ions in the electrolyte are attracted to the positively charged anode. This causes the electrons on the anode to flow through the oxide layer to the cathode and the electrolyte, forming an electrical current. This process is known as red-ox polarization, and it is responsible for charging the capacitor.

When the capacitor is discharged, the electrons on the anode return to the anode and the ions in the electrolyte return to the cathode. This process is know as reverse-redox polarization, and it is responsible for the discharging of the capacitor. By repeating this process, the capacitor is charged and discharged, thus allowing it to store and release a electrical charge.

The T550B256M100BH42520100 tantalum-polymer capacitor is a powerful component capable of meeting the demands of many high-power applications.
