The M39003/01-2657/HSD is a common form factor of a tantalum capacitor and is often used in aerospace and military applications due to its extreme reliability.

Application Field

The M39003/01-2657/HSD is a popular capacitor type used in many high-reliability applications, such as aerospace and military. It has the standard lead corrosion resistant finish so it can survive prolonged exposure to harsh environments. The capacitor also has multiple chassis mount configurations, which adds further reliability for these types of applications. Tantalum capacitors also offer greater electrical stability compared to other capacitor types, making them a popular choice for high-end consumer electronics.

Working Principle

Tantalum capacitors are a type of electrolytic capacitor that use two solid, anode and cathode electrodes. The standard base tantalum material core is embedded in a synthetic semiconductor material called tantalum pentoxide. This material acts as a dielectric, which is the material that separates the two electrodes and is responsible for the capacitor’s electrical properties. The anode metal is a conductive material and forms a capacitor core, surrounded by an oxide layer of dielectric. The other electrode consists of an electrolyte solution in contact with the cathode. When a voltage is applied across the device, the resulting current flow causes the oxide layer to increase in size, forming a larger capacitor.

Tantalum capacitors allow for much higher capacitance values compared to other types of capacitors due to their extremely thin oxide layer. This is why they are so effective in applications that need a large amount of capacitance in a small footprint. They are also known for their noise protection capabilities which make them great for electronic circuits that are sensitive to high frequency noise.
