Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are the highest per-area capacitance and one of the most valuable types of capacitor. A type of variable capacitor, tantalum capacitors use an oxide layer to isolate their conducting material from the active electrode. Composed of a metal case, tantalum capacitors can be used for a wide range of applications, from consumer audio systems to military hardware.The M39003/09-0361/TR, specifically, is a type of surface mount tantalum capacitor designed for use in military and industrial applications. This tantalum capacitor is rated at 18V, with a capacitance of 51uF and a tolerance of 10%. The M39003/09-0361/TR has a temperature coefficient of -15%, and are rated for 3500 hours at their rated voltage. These capacitors feature a lead-free terminations and are designed to meet stringent reliability requirements.Tantalum capacitors are versatile, useful in a variety of applications due to their small size and high performance. In military or aerospace applications, tantalum capacitors are used to store energy in onboard systems, helping improve energy efficiency and reliability in mission-critical systems. In consumer electronics, they are used in power supplies, video cards, and other devices where their relatively small size provides a convenient form factor.The working principle of a tantalum capacitor is based on the basic electronics theory of capacitance. In general, a capacitor can be thought of a device which stores charge. This is done by using two conductive materials, separated by an insulating layer called a dielectric. When a voltage is applied to the two conductive plates, one of them is negatively charged while the other is positively charged, with an electric field between them.The dielectric in the case of the M39003/09-0361/TR is an oxide layer, which allows the capacitor to store a relatively large amount of charge. This increases the performance of the capacitor and its ability to handle high current and voltage. The metal case which houses the capacitor also serves to protect the oxide layer, as it is a fragile material which must be insulated from the surrounding environment.Tantalum capacitors are one of the most reliable and versatile capacitor options currently available on the market. The M39003/09-0361/TR is a particularly robust example, offering high reliability and performance in extreme conditions. It is an excellent choice for a variety of military, industrial, and consumer applications. Its small size and high performance make it an ideal choice for applications where size and performance are of paramount importance.
