Tantalum capacitors are popularly used in circuit designs requiring high capacitance in a small package. The M39003/03-2057H is a tantalum capacitor that offers excellent electrical and thermal characteristics for various applications. This article will discuss the application fields and working principle of the M39003/03-2057H.

The M39003/03-2057H is a polymer-cased capacitor, which offers low ESR (equivalent series resistance) and low self-heating compared to other capacitors. It is mainly used for lots of electronic applications. These include decoupling, energy storage, and biasing in DC-DC converters, choppers, offset voltage generation, and signal coupling. In radio communications, the tantalum capacitor is used for impedance matching and frequency tuning.

The M39003/03-2057H capacitor utilizes a manganese dioxide cathode system, which provides a long-term reliability. The cathode system reduces the risk of electrolyte drying and increases the capacitor’s long-term reliability. It also offers a high capacitance density of 1,400uF/in3 at a case size of 4.5mm and an operating temperature of up to 125oC.

The M39003/03-2057H also has an improved tolerance of +80/-20%. This provides the capacitor with good stability under varying conditions. Additionally, it has increased capacitance stability over the rated temperature range of -55oC to +125oC.

The working principle of this capacitor is based on the electrostatic field created between two conductors which are separated by dielectric material. In the capacitor, one of the conductors is an anode which is made of tantalum metal foil and the other is a cathode which is made of manganese dioxide. The anode is connected to a positive voltage and the cathode is connected to a negative voltage. This results in an electrostatic field between anode and cathode. When an AC voltage is applied, electric charge builds up and flow to the negative conductor.

The graded dielectric causes the electric field to increase rapidly with the increase of the potential. This produces a capacitance value. The plate spacing of the capacitor is very thin, ranging from 0.5 to 3.0 micrometers, and hence higher capacitance value is reached in a small package. It also offers a low ESR and low self-heating which makes it ideal for electronic applications.

Overall, the M39003/03-2057H is a high-performance polymer-cased capacitor from the Rel’s PTC family. It is designed for high capacitance density, low ESR, and low self-heating, making it ideal for use in electronic applications. The capacitor utilizes a manganese dioxide cathode system and has an improved tolerance of +80/-20%. The working principle of the capacitor is based on the electrostatic field created between two conductors, one of which being an anode made of tantalum metal foil and one of which being a cathode made of manganese dioxide.
