Application Field of M39003/01-2316

The M39003/01-2316 is a type of axial lead surface mount tantalum capacitor. As such, it is ideal for use in applications such as synchronous motors or CMOS memory chipsets, which require a low-leakage current, as well as high capacitance and small size. It is also used in power supplies and signal conditioning, as it can handle high voltage switching and offers stable performance. Furthermore, due to its high-performance plastic body, it is shock and vibration resistant, making it suitable for use in military and aerospace applications.

The M39003/01-2316 is available in three sizes, as specified by case size 0303 (EIA Metric M), 0404 (EIA Metric M5) and 0505 (EIA Metric M5.5). The capacitance values range from 570µF to 470µF for the 0303 and 0404 sizes, and from 570µF to 470µF for the 0505. It can operate at temperatures from -55°C to +105°C, with a rated voltage of 10 to 35 VDC and a maximum temperature of 65°C.

Working Principle of M39003/01-2316

Tantalum capacitors, such as the M39003/01-2316, operate by utilizing a tantalum pentoxide (Ta2O5) film as the insulating material between two metal plates. When the energy source applies a voltage, this causes the charge carriers to flow across the oxide film and create a static electric field. This causes the electric charge to be stored in the capacitor, and so it is able to act as an energy store while the energy source is disconnected.

The physical structure of the M39003/01-2316 consists of two metal electrodes; an anode and a cathode. These two electrodes are separated by a tantalum pentoxide dielectric film. As current flows between the electrodes, it creates a static electric field, which causes charge carriers to accumulate on the dielectric film, creating a capacitance. The capacitance of the device is then dependent on the size and thickness of the electrodes, as well as the dielectric permittivity of the oxide film.

The M39003/01-2316 is also notable for its low impedance properties. This is due to the fact that the dielectric film contains manganese dioxide (MnO2). This material is able to reduce the rate of leakage current, thus increasing the reliability of the capacitor and prolonging its life.

Conclusion

The M39003/01-2316 tantalum capacitor is a popular device for use in military and aerospace applications, due to its small size and robust design. Its capacitance range makes it suitable for a variety of applications, such as synchronous motors and CMOS memory chipsets. It also possesses low impedance properties, making it highly reliable and long-lasting. Its working principle relies on the use of tantalum pentoxide and MnO2 as dielectric films, which allow for the build-up of charge carriers, creating a static electric field and thus enabling capacitance.
