Introduction to Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, which use tantalum as an anode material. They are widely used in consumer electronics, because of their low cost and long lifetime. Tantalum capacitors are usually available in two forms: solid or electrolytic. Solid tantalum capacitors have a lower ESR than aluminum electrolytic capacitors, while electrolytic tantalum capacitors have a higher ESR but can offer higher capacitance.

M39003/01-5358H Application Field and Working Principle

The M39003/01-5358H is a surface mount tantalum capacitor manufactured by Johonson Electric and Electronics Corporation. It is designed for military and aerospace applications and features a high-temperature performance of 200ºC. The M39003/01-5358H is a polarized capacitor, meaning it requires a positive DC voltage applied between its anode and cathode to operate correctly. It has a voltage rating of 16 VDC, and its capacitance ranges from 10uF to 35uF.Like other electrolytic capacitors, the M39003/01-5358H is composed of a tantalum anode, dielectric, and an electrolyte to form the structure. The anode and electrolyte are separated by a thin layer of oxide called the dielectric layer or dielectric. This oxide dielectric layer has a large capacitance, meaning it allows electrons to flow through it with minimal resistance. The anode and electrolyte are connected by an electrolyte, which is an ionic solution of salts and liquids. In the case of the M39003/01-5358H, the electrolyte is composed of boron trifluoride and ethanol. When an external voltage is applied to the capacitor, a current will flow through the dielectric layer, creating an electrical field and enabling the capacitor to store an electrical charge. This electrical charge is stored in the dielectric and remains stored until the applied voltage is removed. This is why tantalum capacitors are often referred to as “non-polar” or “non-polarisable” capacitors. The M39003/01-5358H has a high-temperature performance of 200°C, which makes it ideal for use in military and aerospace applications, where temperatures can reach high levels. It can also withstand mechanical shock and vibration, and has superior humidity and temperature performance, making it suitable for high-end consumer electronics applications.

Advantages of Tantalum Capacitors

Tantalum capacitors offer many advantages that make them attractive for use in a wide variety of electronic applications. These include improved temperature and humidity performance, better shock and vibration resistance, lower ESR, and higher capacitance than other electrolytic capacitors. Tantalum capacitors are also smaller in size than other types of capacitors, making them ideal for use in space-constrained applications. This is because the dielectric layer is thinner than in other types of capacitors, which results in a smaller size. Furthermore, tantalum capacitors offer higher reliability and longer lifetimes than other types of capacitors.

Conclusion

The M39003/01-5358H is a surface mount tantalum capacitor designed for military and aerospace applications, and features a high-temperature performance of 200°C. It offers a wide range of benefits, such as low ESR, higher capacitance, better temperature and humidity performance, and improved shock and vibration resistance. Tantalum capacitors are used in a wide variety of applications, due to their small size, improved reliability, and long lifetimes.
