Tantalum Capacitors

Tantalum capacitors are a type of capacitor used in many electronic circuits, notably mobile phones and computers. They are available in both leaded and surface-mount styles, as well as with various form factors. Their small size, low profile, and low impedance make them particularly well-suited for use in portable devices. Although most designs use manganese dioxide as the electrolyte, there are also tantalum capacitors with organic and polymeric electrolytes. The M39003/09-2037/TR is a tantalum capacitor with an organic electrolyte.

Application Field for M39003/09-2037/TR

The M39003/09-2037/TR tantalum capacitor is a standard surface-mount type and is designed for use in a wide range of applications, including power management for high-voltage applications, audio system power supply filter power architecture, and high-efficiency motor drive controllers. It is also used in medical equipment, automotive electronics, defense applications, and many other electrical and electronic circuits.

Working Principle of M39003/09-2037/TR

Tantalum capacitors work in a similar way to other types of capacitors. They can store a charge when two conductors separated by a dielectric material are connected to a voltage source. A voltage will be supplied to the conductors, and the capacitance of the capacitor is determined by the surface area of the conductors and the dielectric constant of the material between them. When the capacitor is connected to the voltage source, a charge will be stored in the capacitance. This stored charge can be used as an energy reservoir to provide energy to another circuit.

The M39003/09-2037/TR tantalum capacitor is a surface-mount device, meaning it is designed to be soldered onto a printed circuit board. The construction of the device consists of a cylindrical anode of sintered tantalum powder, with an organic electrolyte, such as methane sulfonic acid, impregnated into the powder. The anode is sealed in a nickel/cadmium composite case. On top of the anode is a ceramic dielectric layer, and above it is the cathode. Both contacts then lead to a lipped or flat seal. There is also a safety valve that releases pressure should the capacitor be over-pressurized due to a failure in the system.

Tantalum capacitors are widely used due to their low cost, compact size, and low equivalence series resistance. In addition, their organic electrolyte makes them resistant to temperature, vibration, and shock. The M39003/09-2037/TR device has a voltage rating of 18V, a capacitance range of from 13 μF to 330 μF, and a temperature range from -55°C to 85°C. Combined, these features make the M39003/09-2037/TR an excellent choice for a variety of applications.
