Tantalum capacitors, also known as TaNcap, are a type of capacitor typically composed of tantalum and a conductive material, such as manganese-oxide. Tantalum capacitors are known for their high stability and reliability in power circuits, high capacitance and long lifetime. They are widely used in mobile phones, consumer electronics, medical equipment, military, and aerospace markets.

The NCR 199D186X9025D6B1E3 tantalum capacitor is a high-quality surface mount component designed for commercial, industrial, aerospace, and military applications. It has long lifetime and low leakage. The capacitor is composed of a manganese-oxide dielectric material and a two-terminal tantalum anode overmolded with a conductive epoxy resin. This provides excellent electrical and mechanical stability and superior surge and shock resistance, making them suitable for high vibration environments. The anode is constructed from pure virgin metal tantalum for superior performance and reliability which allows for high capacitance values in a limited space.

The 199D186X9025D6B1E3 tantalum capacitor has a rated capacitance of 47µF with a ±20% capacitance tolerance at a rated working voltage of 6.3V DC. It has a maximum temperature range of -55°C to 85°C and a maximum DC leakage current of 7.5µA at 25°C. It is non polarized which means it can be used in both AC and DC circuits.

The working principle of the tantalum capacitor is based on capacitance. A capacitor is a device which stores electric charge. In a tantalum capacitor, the energy is stored in the form of electric fields between metallic plates. The electric fields increase as more charge is applied to the plates. The capacitance of the capacitor is calculated based on the inverse relationship of the electric field to the area and distance between the two plates. The amount of charge a capacitor can store is determined by the amount of electric field and the capacitance.

Tantalum capacitors offer reliable performance in high frequency signal settling, AC line filters, and bypass applications. They are commonly used in applications where a large amount of energy can be stored quickly, such as in power supplies or filters. The high stability, long lifetime, and low leakage of tantalum capacitors make them ideal for use in military and aerospace applications, as they can withstand extreme temperatures and vibration.
