Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitors. Tantalum Materials get its name, tantalum, from Tantalus, a mythological Greek deity. The mythological character Tantalus was cursed with eternal punishment; similar to how tantalum provides electrical components with a form of reliable, longlasting protection from electrical surges.

Tantalum capacitors use an oxide layer that forms a dielectric on the surface of a high-purity sintered tantalum anode, and a solid electrolyte of manganese dioxide, which is wrapped in a metallic casing. The 150D475X0075R2T, is constructed with a standard cases size and capacitance ratings.

Application Field

Tantalum capacitors are ideal for applications in automotive, medical, military, telecommunications, industrial equipment, and consumer electronics products. Unsintered tantalum capacitors can resist vibration, shock, sudden temperature changes, and severe environmental fluctuations. Moreover, the 150D475X0075R2T capacitor, specifically, offers a higher capacitance and voltage ratings providing increased levels of efficiency in a compact, lightweight form factor.

Working Principle

When current is applied, the oxide layer of the tantalum capacitor attracts the oxygen to itself. The anode then oxidizes, forming a capacitive dielectric in the process. The dielectric layer encapsulates the anode, forming a barrier that stores electric charge. The 150D475X0075R2T capacitor makes use of a capacitor shell, which serves as a cathode that supplies electrons to the anode.

The operating voltage that can be applied to the capacitor depends on the thickness of the oxide film, and the distance between the anode and cathode. The 150D475X0075R2T capacitor has a very low leakage current, allowing it to maintain a good level of capacitance over a wide range of operating voltages.

The tantalum capacitor is very versatile and can be used in a variety of applications. This includes power supplies, filters, matches, timing circuits, phase-shift networks, active-component tuning circuits, and voltage-regulators. The 150D475X0075R2T is also suitable for RF applications, including FM modulation systems.

Coupled with its superior stability and low cost, the 150D475X0075R2T tantalum capacitor is well-suited for a wide variety of industrial, commercial, and consumer applications. It offers excellent reliability, which is why it is so widely used in military and aerospace applications.
