Tantalum - Polymer Capacitors

Tantalum-polymer capacitors combine the best features of Tantalum capacitors and Polymer capacitors. They have a higher voltage and larger capacity for lower ESR than tantalum capacitors, and are less temperature sensitive than polymer capacitors. M550B257M100AS is one of the most popular models of Tantalum-polymer capacitors, and it is widely used in many electronics and electrical applications.

Application Field

M550B257M100AS is mainly used to provide stable voltage in high-current applications, such as power supplies, motor control circuits and motor drives. It can also be used in other low-power applications, such as sleep current (battery backup) circuits, decoupling circuits and energy storage components, as well as in the manufacture of printed circuit boards for stability and reliability.

Working Principle

Tantalum - polymer capacitors have a unique construction, which combines the features of a tantalum capacitor and a polymer capacitor. A tantalum anode is covered with a polymer dielectric material and then a galvanic or anodic oxidation process is used to form an extremely thin, electrically insulated and extremely robust dielectric layer, which is sandwiched between the anode and a metallic cathode.

The anode of the M550B257M100AS is made of pure and noble tantalum, with excellent electrical properties and low ESR (equivalent series resistance). The dielectric layer is made of polyvinyl alcohol, a polymeric material which has excellent dielectric properties. The use of polyvinyl alcohol as a dielectric layer gives the capacitor a high degree of insulation, thereby reducing the risk of short-circuit failure. The metallic cathode is made of stainless steel, which is resistant to oxidation and provides excellent conductivity.

M550B257M100AS capacitors are highly stable and reliable, and can withstand a wide range of temperatures and atmospheres. They are also capable of withstanding high peak voltages and charge/discharge cycles. When used in critical applications, such as power supplies and motor drives, M550B257M100AS capacitors are a reliable option for providing stable voltages.
