Tantalum capacitors are a type of electrolytic capacitor consisting of tantalum powder pressed into a pellet shape and coated with a metal oxide such as tantalum pentoxide. It is a device that stores electrical energy and enables the release of current instantaneously. The M39006/22-0025 series of tantalum capacitors is ideal for high temperature, high frequency, and high vibration applications.

The M39006/22-0025 series of tantalum capacitors provide a low minimum and maximum capacitance of 0.12µF and 2.2µF, respectively, and a voltage range of 6.3 to 50VDC. They are available with case size codes of C, E, F, G, H, J, K, and M depending on the capacitance and voltage range. The capacitors provide a high capacitance to weight ratio with an overrated capacitance range of 18-10% at 85°C ambient temperature. The performance characteristics of the M39006/22-0025 series of tantalum capacitors make them well suited for use in a variety of automotive, telecommunications, and aerospace applications.

The general working principle of tantalum capacitors is based on the principle of double electric layers of positive and negative ions separated by an ionic solution. The presence of colloidal particles, such as tantalum pentoxide (Ta2O5) or manganese dioxide (MnO2), serves as the dielectric material in such a device. The electrodes of the capacitor are composed of sintered tantalum powder, which is compressed between a foamed intumescent and an insulating layer. When a voltage is applied across the capacitor, a diffusion of ions occurs between the electrodes. This causes positive charges to accumulate on one side and negative charges on the other, thus forming a double-layer capacitance. The ability of the tantalum capacitor to store energy depends on the size of the unit as well as the applied DC voltage.

The M39006/22-0025 series of tantalum capacitors offer a range of features that make them ideal for use in a variety of applications. These features include excellent stability, low ESR, high ripple current, and long-term reliability. In addition, the devices are designed for operation at temperatures up to 150°C and are available as polarity sensitive and non-polarity sensitive versions. The non-polarity sensitive version also allows the use of both positive and negative voltage, making it suitable for AC applications. Due to their high temperature performance, M39006/22-0025 series of tantalum capacitors are ideal for use in automotive, telecommunications, and aerospace applications.
