Tantalum capacitors are a type of electrolytic capacitor, often in surface mount technology packages. Due to their small size and high capacity they are widely used in laptop and notebook computers, PDAs, and other electronic devices. The main difference between tantalum capacitors and other electrolytic capacitors is the material used for the capacitor plates. Tantalum capacitors use tantalum metal powder coated with a metal oxide surface layer as their capacitor plates compared to aluminum oxide electrolyte material that is used in other electrolytic capacitors. This gives them greater stability, higher capacitance and superior temperature stability compared to aluminum electrolytic capacitors.

M39003/01-2775 is a high reliability, surface mount tantalum capacitor manufactured by Vishay. It has an operating temperature range of -55°C to +125°C, an ESR of 0.9 ohm and a capacitance range from 0.1µF to 680µF. It is a “snap in” capacitor device, meaning it has two sets of metal plates that snap together to form the basic structure of the capacitor. It has two sets of pins that make contact with the device so that it can be soldered onto the circuit board. The pins are also plated with a metal such as nickel or gold to provide extra corrosion resistance. The device works on the same principle as other types of capacitors; it stores a charge in the form of electrical energy on its plates.

M39003/01-2775 has a wide range of applications where reliability and small size are important. It is used in a variety of industrial and military applications, such as automotive electronics, communications, computers, and medical equipment. The capacitor is particularly popular in high-speed digital circuits like multi-gigabit memory interfaces, due to its low ESR values and wide operating temperature range. The capacitor is also used in high temperature aerospace applications and high reliability circuits, due to its proven capability of passing many MIL-STD-202 tests, as well as several vibration tests for shock and vibration resistance.

The working principle of the M39003/01-2775 capacitor is based on the same principles as other electrolytic capacitors. When the device is connected to the power source, a voltage and current are applied, causing a charge to be stored in the device. The rate at which the charge is stored is determined by various factors, such as the size of the plates, the dielectric material between the plates, and the amount of voltage applied. As the voltage increases, the conductivity of the dielectric material increases and more charge flows across it. This increases the amount of charge stored in the plates, which is measured in Farads. When the voltage is removed, the charge stored in the plates discharges, releasing the energy back into the circuit.

The M39003/01-2775 tantalum capacitor is a valuable component for many industrial and military applications. Its high reliability, small size, wide operating temperature range, and high capacitance make it a popular choice for many applications. It is used for storing electrical energy in digital circuits, providing power for medical equipment, and providing voltage stabilization in automotive applications. By understanding the working principle of the M39003/01-2775 tantalum capacitor, one can better determine when and where to use it in their applications.
