Tantalum Capacitors

Tantalum capacitors, commonly referred to as “tantalum caps”, are specialized aluminum electrolytic capacitors containing an electrolyte of tantalum pentoxide. Their design is similar to that of the aluminum electrolytic capacitors, but with two main differences: a fixed dielectric (tantalum) and an electrolyte of tantalum pentoxide. These features enable tantalum caps to achieve much higher voltage ratings and much better temperature behavior compared with aluminum electrolytic capacitors.

The T350D335K035AT is a type of tantalum capacitor that plays a critical role in the defense and aerospace industries. The T350D335K035AT has a capacitance of up to 350µF, a voltage rating of at least 335V DC and a reliability of 0.00035% per 1,000 hours at +85°C. It has excellent wetting characteristics that make it suitable for soldering and rework and it is also miniaturized, making it ideal for compact circuit applications.

Application Field

Tantalum capacitors like the T350D335K035AT are primarily used in aerospace, military, and medical applications where reliable operation and long life is critical. This type of capacitor is widely used in space and defense applications, ranging from high-end communication systems to radar systems and early-warning systems for missile defense. It is widely used in missile tracking systems and navigation guidance systems, since its long-life, good mechanical stability and low ESR features may significantly improve system reliability.

The T350D335K035AT also plays an important role in electronics assemblies that must withstand vibration and environmental stress, such as Military Standard 883-mode testing. Its long life, reliability, and excellent vibration resistance make the T350D335K035AT an ideal choice for those who require a robust and reliable circuit assembly.

The T350D335K035AT is also popular in medical applications, such as in medical imaging and surgical systems, where high reliability and stringent safety standards are needed. The T350D335K035AT is also suitable for military-grade flight and navigation systems, since it is capable of handling a wide variety of environmental conditions without compromising performance or reliability.

Working Principle

Tantalum capacitors have a very similar design and operating principle to traditional aluminum electrolytic capacitors. The anode is composed of tantalum metal that forms an oxide layer during the manufacturing process. This oxide layer acts as a dielectric, providing insulation between the anode and the cathode. The cathode is typically composed of an aluminum-based electrolyte and a heated electrolyte containing an alkali containing compound like potassium hydroxide.

The operating principle of the T350D335K035AT is similar to that of traditional aluminum electrolytic capacitors. When a voltage is applied across the capacitor, the oxidation of the tantalum metal results in a buildup of electrostatic charge and a voltage potential across the device. This potential provides the capacitor with the ability to store and release electrostatic energy, thereby providing power to the circuit.

The high capacitance, long life and excellent mechanical stability of the T350D335K035AT make it an ideal choice for many applications. Its reliability, excellent vibration resistance and cost-effectiveness make it well suited for the demanding and rigorous environments found in defense and aerospace applications.
