Tantalum Capacitors: M39003/03-0155/HSD Application Field and Working Principle

Tantalum capacitors are a type of electrolytic capacitors, which are distinguished from other types of capacitors by their distinctive shape and use of tantalum material. The M39003/03-0155/HSD is a tantalum capacitors with a high accuracy and low height, making it ideal for board level applications.This type of capacitor is made up of two electrodes, an anode and cathode, connected to a dielectric material tantalum pentoxide. The anode electrode is usually made from a vapor-deposited layer of tantalum metal, while the cathode is usually made from a specially assorted base metal oxide. The two layers are separated by a electrolyte dielectric material such as tantalum pentoxide or titanium dioxide.These capacitors are used in many applications, including telecommunications, and industrial and medical applications. The high accuracy, low voltage rating, long term reliability of this type of capacitor make it well-suited for use in a wide variety of applications. The capacitors are also typically quite inexpensive, making them a viable option for low cost designs.The M39003/03-0155/HSD is designed to offer very low equivalent series inductance (ESL) and low impedance in the range of several microohms. Due to the high accuracy, low voltage rating and long-term reliability, it is suitable for various generalpurpose circuit designs, such as oscillators, stimulators, power supplies, decoupling circuits, sample and hold circuits, or signal conditioning filters.The M39003/03-0155/HSD also features a wide range of capacitances, ranging up to 1000 μF and 2.5V. The operating temperature range for this type of capacitor is from -55°C to +85°C so it is suitable for harsh environments. The low voltage version is rated down to 6.3V and up to 25V, while the high voltage version is rated up to 50V.The M39003/03-0155/HSD is a radial leaded type, making it ideal for surface mounting on PCBs. They have a wide tolerance of ±10%, so they can provide stable voltage and current regulation. The capacitance is also marked on the body of the capacitor and is designed to retain its capacitance and voltage even after long term use.The working principle of the M39003/03-0155/HSD is very similar to other types of capacitors – by controlling electric current flow. The current is transferred between the anode and cathode via the dielectric material, which causes a voltage difference between the two. This voltage difference is the capacitance of the capacitor, and is measured in Farads. At a higher voltage, the current flow is decreased, and a higher capacitance is created. At a lower voltage, the current flow is increased, and a lower capacitance is created. This is why it is common for high voltage tantalum capacitors to have a larger capacitance than low voltage ones.The M39003/03-0155/HSD is designed for use in various general-purpose applications. It offers a good combination of performance, cost, and size, making it a popular choice for design engineers. Its wide operating temperature range and low impedance make it ideal for high reliable and rugged applications in harsh environments.
