Tantalum capacitors, or tantalum electrolytic capacitors, are a type of capacitor that offers a high-capacity equivalent to its relatively small physical size. It typically consists of an anode formed from sintered tantalum grains, a platinum group metal oxide cathode and a semiconductor layer containing fluoride ions. Tantalum capacitors have a wide variety of general and specific electrical characteristics that make them suitable for many applications. The TAP226K020SRW is a high-temperature aluminum polymer capacitor used in aerospace applications.

The TAP226K020SRW is a three-terminal, surface-mount device suitable for use in extreme heat environments. Constructed with a tantalum anode, a high-temperature anodized aluminum substrate, an electrolytic polymer and an aluminum cathode, this tantalum capacitor boasts superior high-temperature performance. It is capable of operating up to +225°C in temperatures and offers up to a 2,000 hour life when used in its rated environment. This capacitor is also very reliable, with an MTBF rating of more than 500,000 hours.

The principal applications of the TAP226K020SRW are in defense, aerospace, and ground-based systems, as well as in automotive and industrial applications that require high-temperature operation. Its use in military/aerospace systems provides for reliable connection of communications, navigation and surveillance systems. The capacitor is also used in both analog and digital applications that require reliable performance in extreme heat environments, such as LED lighting, factory automation, and heath/temperature sensors. Due to its high-temperature performance, the capacitor is also suitable for use in industrial and embedded systems, allowing for uninterrupted operation across a wide temperature range.

The working principle of the TAP226K020SRW is based on electrochemical action. Like all other types of capacitors, its principle of operation is based on the principle of capacitance. It is basically a device that stores energy in an electrical field established between two nonconductive layers (electrodes) separated by a substance known as dielectric. The energy stored in the electric field increases when the electric charge stored on the electrodes increases. When the capacitor is connected to a power source, such as a battery or AC/DC voltage source, electrons flow in one direction to create an electrical field that continues to stored energy until the power source is removed.

The TAP226K020SRW provides a quality capacitance element which offers a combination of high capacitance density, low equivalent series resistance (ESR), high-current capability and a long operating life. Its design includes a polypropylene dielectric and anodized aluminum layers that work together to provide superior heat and current protection. Its low-ESR, low-voltage design ensures reliable connection and increased performance. The operating life of this capacitor is guaranteed to exceed 2,000 hours in rated environments and results in a reliable, long-lasting product.
