M39003/01-6285 Capacitors

Tantalum capacitors are one of the most popular types of capacitors used in a variety of applications, from automotive electronics to aircrafts. The M39003/01-6285 is a miniaturized resistive-chip capacitor, specifically designed for use in space-restricted applications that require high reliability. Its small size and light weight make it appealing for aerospace and defense applications. This paper describes the application field and working principle of the M39003/01-6285 capacitor.

Application Field

The M39003/01-6285 capacitor is an advanced, high-temperature and pressure-resistant capacitor that can be used in a variety of extreme environments. It is primarily used in aerospace and defense applications such as satellite electronics, missiles, aircraft and space shuttles, due to its low profile and extreme reliability. Additionally, it can be put to use in other challenging applications such as automotive, medical, and mobile communication systems.

Working Principle

Tantalum capacitors work on charging and discharging electric fields. They acquire their capacitance from the two metallic plates called “electrodes” that are in contact with a dielectric layer, which can be aluminum oxide, tantalum pentoxide or manganese oxide. The core of the capacitor consists of two capacitive elements, the anode (positive side) and the cathode (negative side). When electric potential is applied to the capacitor, electrons accumulate on the cathode while electric holes accumulate on the anode, creating an accumulation electric field. This results in the capacitor being able to store energy.

When the capacitor is taking in energy, the current flows from the anode to the cathode, creating an electric field. This electric field allows the capacitor to store charge. When the capacitor is discharging, the electrons move from the cathode to the anode, and the charged electric field is decreased, causing the capacitor to release charge. This is how the M39003/01-6285 works in practical applications.

Conclusion

The M39003/01-6285 capacitor is a miniature resistive-chip capacitor, with an excellent performance in space-restricted applications. The device is widely applied in aerospace and defense as well as other extreme applications, due to its high reliability and miniaturized size. Its working principle involves charging and discharging electric fields, where electrons accumulate on the cathode while electric holes accumulate on the anode, creating an accumulation electric field.
