Tantalum Capacitors: 150D156X0060S2T Application Field and Working Principle

Capacitors are widely used in various industries, including consumer electronics, telecommunications, and automotive. Among them, tantalum capacitors are widely used for their high-performance characteristics, such as low ESR, low losses, and high-temperature stability. The 150D156X0060S2T, a type of low-ESR, high-capacitance tantalum capacitor, is a dust-free, leadless MLCC soldering capacitor with an operating temperature range of -55℃ to +130℃.

Application Field

The 150D156X0060S2T is an ideal choice for applications that demand high-capacitance and low-ESR in a tiny footprint. It is used in products such as cell phones, PDAs, digital cameras, home appliances, consumer electronics, automotive, and computers. This high-capacitance, low-ESR capacitor ensures maximum performance while taking up minimal space.

Working Principle

Tantalum capacitors are solid electrolytic capacitors, where tantalum oxide is the dielectric material. Due to their construction, they are known as polarised capacitors since the choice of the polarity is important. The capacitance of the 150D156X0060S2T is determined by the use of a porous tantalum anode covered by a surface layer of the oxide and containing a conductive electrolyte, usually aqueous-based KOH. When connected to a voltage source, the electric current through the capacitor’s anode results in the cathode being charged, thus creating an electric field with two oppositely charged plates and a dielectric in between.

The resulting capacitance also depends on the size of the electrode plates and the distance between them. The thinner the dielectric material, the higher the capacitance. Notably, regular tantalum capacitors have a quite high ESR compared to other capacitor types. This is because as the current passes through the anode to form a dielectric oxide layer, there is an energy loss caused by the internal series resistance.

Due to the high-capacitance and low-ESR characteristics, the 150D156X0060S2T tantalum capacitor is an ideal choice for applications that demand high performance and miniaturised sizes. This capacitor is capable of safely and efficiently supplying power to a wide range of applications, while ensuring excellent temperature stability and long-term reliability.
