Tantalum capacitors are surface mount capacitor elements with potentiometer-like properties, offering the advantages of wide capacitance range, high efficiency, good frequency response and low profile for the devices they comprise. M39003/01-8114H is one type of such capacitors, whose application field and working principle are highlighted below.

Application field

M39003/01-8114H tantalum capacitors are mainly used in projects involving high-frequency signal processing and in the storage of electronic signals. The capacitance value of this type of capacitor is small, usually ranging from 1 to 47 µF, with voltage rating ranging from 4V to 62 VDC. It is often used in resonance circuits, low-frequency signals and energy storage. Other applications include the filtering of power supplies, and in applications involving high-voltage surge, high-voltage alternating current, and specialized noise suppression.

Working Principle

A M39003/01-8114H tantalum capacitor is composed of a solid-state material such as tantalum powder or grains which are conductively insulated and packed in a thin metal case. The charge on the capacitor is supplied by a low voltage positive direct current source and is stored and discharged as needed. When current is applied, it causes a release of electrons from the grains of tantalum, creating a positive charge on the surface of each grain. This process continues until the capacitor has reached its maximum charge and can no longer accept any additional electrons. The charge is then dissipated by means of a reverse current.

The structure of the M39003/01-8114H capacitors allows them to withstand temperatures up to +125°C. This is due to their highly reliable tantalum powder construction, which provides for a stronger binding force of the grains within the capacitor than other types of capacitor material. The current leakage of these capacitors is also very low, due to the use of non polarizing charge carriers.

The M39003/01-8114H tantalum capacitors are also very small in size, making them well suited for applications in which space is a premium. The capacitors come in both through-hole and surface-mount formats, so they can be easily integrated into various platforms. Their dark coating also makes them resistant to abrasion, moisture, salt, and chemicals.

In conclusion, M39003/01-8114H tantalum capacitors find diverse applications in the areas of signal processing, energy storage, and power supply filtering. The capacitors offer high efficiency, wide capacitance, low leakage, excellent frequency response, and a high surge capability. With their small size, capability to withstand high temperatures, and reliable construction, they are an ideal choice for low-cost, high-performance capacitors.
