Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor, which consists of a pellet of tantalum metal powder as an anode, covered by an insulating oxide layer that acts as the dielectric, surrounded by liquid or solid electrolyte as a cathode. These capacitors are frequently used for their distinctive combination of excellent stability, high capacitance, and small size. Due to this, they are ideal for use in a range of different applications.

M39003/01-2408/TR application field and working principle

The M39003/01-2408/TR is a tantalum capacitor that is designed to provide stable electrical performance over a wide range of frequencies and temperatures. It is available in two versions, the “A” version, with an extended temperature range up to -55°C, and the “B” version, with an extended temperature range up to +105°C. This capacitor uses an anodized tantalum pellet, with an insulated foil dielectric, and a solid electrolyte. It is designed for use in extreme temperature ranges, and is well-suited for automotive, avionics, and military grade applications.

The capacitor works by creating an electric field between two conductive plates, a cathode and an anode, where the cathode is held at a higher electrical potential than the anode. This field stores energy in the form of an electric charge, which is then discharged when the capacitor is connected to a circuit. In a tantalum capacitor, the anode is made from a pellet of tantalum metal, which is coated with an insulating oxide layer that acts as the dielectric.This is then surrounded by either a liquid or solid electrolyte, which acts as the cathode. When a voltage is applied to the capacitor, the tantalum pellet is polarized, and a layer of oxide forms on its surface. This layer creates a barrier between the metal and the electrolyte, which in turn, acts as the capacitor’s dielectric layer, allowing it to store electric charge.

The M39003/01-2408/TR is designed for use in applications that require a high degree of stability and reliability. Its solid electrolyte design means that it is very resistant to corrosive environments, and its low impedance makes it well suited for use in high frequency circuits. In addition, it is capable of withstanding extreme temperature ranges, making it ideal for use in military, avionics, and automotive applications.
