Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor. They operate similarly to other electrolytic capacitors, in that they use an electrolyte to store charge. What sets the tantalum capacitor apart is its higher capacitance values per unit volume, and its wide temperature range, making it ideal for high frequency, high power and demanding applications. The M39003/09-0037H is a commercial grade radial leaded tantalum capacitor which offers excellent performance in demanding applications.

M39003/09-0037H Application Field and Working Principle

The M39003/09-0037H is a radial leaded tantalum capacitor used primarily in military and aerospace applications. It is well-suited for many high-frequency, high-power operations such as variable frequency drives, power amplifiers, switched mode power supplies, and high frequency PWM motor control circuits. It is also ideal for use in computer motherboards, active filters, audio and video circuits, and industrial control systems, where its reliability, long-term performance, and temperature range make it an invaluable component.

How does a tantalum capacitor work? At its simplest, it acts like a battery to store electric charge and provide a voltage supply. The M39003/09-0037H is a polarized capacitor, meaning electricity can only flow one way through it. The positive terminal is typically connected to the anode, which is made of a tantalum material that has been oxidized in order to increase its capacitance. The negative terminal, or cathode, is typically connected to a source of electrons, such as the ground. When positive voltage is applied to the anode, the electrons from the cathode are drawn into the anode and accumulate on its surface, creating an effective storage of electric charge.

The amount of stored charge, or capacitance, of a capacitor is affected by the area of the electrodes and the distance between them. In the M39003/09-0037H, vertical spacing between the anode and the cathode determines the capacitor\'s capacitance, making it perfect for high frequency and high power applications. The capacitance of the M39003/09-0037H can range from 10 µF to 1000 µF, making it suitable for a wide variety of duties.

The M39003/09-0037H has a wide temperature range as well, ranging from -55°C to +125°C. This, combined with its reliable construction, make it an ideal choice for demanding applications where high temperatures and vibration are expected. The tantalum capacitor is also self-healing, meaning it can recover from short-circuits and internal arcs, making it much more reliable and resilient than other types of capacitors.

The M39003/09-0037H is a reliable and robust solution for many mission critical applications in aerospace and military operations. Based on its superior temperature range, robust construction, and self-healing properties, it is ideal for high-frequency and demanding applications.
