Tantalum capacitors, composed of tantalum metal and an oxide layer, are a type of electrolytic capacitor. As one of the most dependable electrical components, tantalum capacitors have a wide range of applications and usages. The M39003/03-3086H is a high-reliability, low-ESR (equivalent series resistance) SMD (surface-mount device) tantalum capacitor. In this article, we take a look at the application field and working principle of the M39003/03-3086H.

M39003/03-3086H Application Fields

The M39003/03-3086H is an SMD solid electrolytic capacitor with an anode made of sintered tantalum, and a dielectric of manganese dioxide. It is used as a storage device in many electronic devices, such as energy conversion systems, power supplies, communication systems, automotive electronics, and LED lighting devices. This capacitor is mainly used for decoupling, smoothing, and energy storage.

M39003/03-3086H Working Principle

The M39003/03-3086H is a polarized capacitor. Its anode is composed of sintered tantalum metal, its dielectric is manganese dioxide, and its cathode is a manganese dioxide-based electrolyte. The anode and cathode are separated by an insulating electrical oxide layer. Thus, when a voltage is applied between the anode and cathode of the capacitor, an electrical field is created which causes the oxide layer to break down and form an electric charge.

The rate of charge storage and release is determined by the capacitance of the capacitor. The higher the capacitance, the greater the charge. When the voltage is removed, the dielectric of the capacitor begins to flow from the anode to the cathode, and the capacitor discharges. The discharge occurs at a rate dependent on the equivalent series resistance (ESR) of the device; the lower the ESR, the faster the discharge.

Conclusion

The M39003/03-3086H is a high-reliability, low-ESR SMD tantalum capacitor. It is used as a storage device in various electronic devices, and its working principle is based on the creation of an electrical field between the anode and cathode of the capacitor, which causes the oxide layer to break down and form an electric charge. The discharge rate of the capacitor is determined by its capacitance and equivalent series resistance. With its wide range of applications and reliable performance, the M39003/03-3086H is an ideal choice for many different electronic devices.
