Tantalum Capacitors

A tantalum capacitor, also known as a tantalum electrolytic capacitor, is an electrolytic capacitor that utilizes tantalum as its anode. It is typically used in many electronic systems such as telecommunication, medical equipment, military equipment and avionics.

Tantalum capacitors are widely used in applications where high reliability, small size, and electrical efficiency are necessary. They are available in many shapes and sizes, from small radial leaded smd capacitors to large axial leaded tantalum capacitors.

The main applications of tantalum capacitors are industrial and medical electronics, computers, communications, avionics, and any system requiring high reliability and long terms stability such as automotive and defense equipment. In addition, tantalum capacitors offer superior electrical performance when compared to other types of electrolytic capacitors.

150D184X9020A2TE3 application field and working principle

The 150D184X9020A2TE3 is a product from Kemet corporation that is a high temperature capacitor designed for military and aerospace applications. It is a bipolar, non-polarized, chip-style tantalum capacitor rated for operating temperatures up to 200°C. The chip type capacitor, which is smaller than common radial leaded tantalums, has two tin-plated terminations for connection to the printed circuit board.

The capacitor has high volumetric efficiency (about 25% of tantalums) and exceeds MIL-PRF-55365M performance level for small size tantalum capacitors. The 150D184X9020A2TE3 chip capacitor also has a higher voltage rating than smaller case size radial-leaded tantalum capacitors.

The capacitor operates using a solution of tantalum pentoxide, which is heated in an oven to "tune" the properties of the electrode material. This "tunning" of the "dielectric" material is necessary to achieve the desired capacitance value for the capacitor. The capacitor is also polarized, meaning it needs to be connected in such a way that a positive voltage is applied to one terminal (the anode) and a negative voltage to the other (the cathode).

The most important characteristics of the 150D184X9020A2TE3 are its high temperature rating (200°C), miniaturization, high capacitance density, and excellent stability with temperature and voltage variations. They are highly reliable, providing shorter lead times than other tantalum capacitors. With its high temperature rating, these capacitors are ideal for applications such as military and aerospace, medical, automotive, and high temperature environments.
