<h2>Tantalum - Polymer Capacitors</h2>Tantalum-polymer capacitors are a type of formed tantalum capacitor which utilizes both tantalum and conductive polymer as the electrodes. They represent a significant progression in the development of cost effective, high volume, solid electrolytic capacitor technology, and have found extensive applications in areas such as digital, automotive and lighting electronics. This article will discuss the M551B828M006AS, its application field and working principle.The M551B828M006AS socket tantalum-polymer capacitors provide a unique combination of very low levels of equivalent series resistance (ESR), extremely long service life, and pure-tantalum core construction, which makes them ideal for a wide range of demanding applications, including low-voltage DC-DC converters, high-current DC circuits, LED lighting power supplies, telecommunication systems and computer peripherals. The M551B828M006AS capacitor has an expanded operating temperature range of -55°C to +125°C and has an excellent shelf life – comprehensive tests since 2012 have demonstrated no measurable change in its performance up to three years. It also features a load life of 2000 hours at +85°C, 0.01 %/ 1,000 hours ESR change, and a rated voltage of 6.3 Vdc.The working principle behind the M551B828M006AS is based on the basic capacitor equation, where the capacitor\'s capacitance is determined by the area of the electrodes and the dielectric constant (K) of the polymer. In the M551B828M006AS, the dielectric constant is provided by a conductive, polymer-based material which encapsulates the dielectric layer. This allows the capacitor to have higher capacitance than traditional solid tantalum capacitors, while significantly reducing its ESR.The M551B828M006AS uses advanced capacitor technologies, resulting in a highly reliable capacitor with consistency in voltage and temperature characteristics. Specifically, its design has a multi-layer bipolar construction with a polypropylene film dielectric and an aggressive, high purity electrolyte. The polypropylene film dielectric layer is constructed using a specially formulated polypropylene resistive system which helps reduce ESR and increases the voltage hold-up characteristics of the M551B828M006AS.The M551B828M006AS also features a unique construction method, where the electrode is deposited in a manner which provides an additional layer of protection against corrosion and aging. The electrolyte layer is also optimized with a high purity tantalum pentoxide (TPO) process which helps improve capacitance stability and provides further protection against leakage.Overall, the M551B828M006AS capacitor is an excellent choice for a wide range of applications. It offers superior performance with its low ESR and leakage current characteristics, superior voltage hold-up and long life. Additionally, its high reliability and consistency in voltage and temperature characteristics make it an ideal choice for a variety of demanding applications.
