Tantalum capacitors are widely used in general electronic equipment, especially in high frequency and high frequency circuit designs. Among the series of tantalum capacitors, M39003/03-2016/TR is one of the common types, which has a wide application range and superb working principle. This section will discuss in detail the application field and the working principle of the M39003/03-2016/TR tantalum capacitors.

Application Field

M39003/03-2016/TR tantalum capacitors are non-polar, hermetically sealed capacitors that have become increasingly popular as a general-purpose alternative to ceramic capacitors. Compared with other capacitors in the market, M39003/03-2016/TR tantalum capacitors have the advantages of small size, good thermal stability, good electrical stability, and high reliability. Therefore, this type of capacitor is widely used in military, commercial and industrial electronics, with an operating temperature range from -55℃ to +125℃.

M39003/03-2016/TR tantalum capacitors are used in precision circuits, especially in high frequency and high frequency circuits. Its outstanding performance is due to its thin, solid Tantalum oxide layer, which covers the surface of the capacitor. The thinness of this layer makes it very sensitive to temperature change, so M39003/03-2016/TR capacitors are not suitable for circuits with high temperature fluctuations. In addition, the operating temperature range of M39003/03-2016/TR capacitors is also narrower than other types of capacitors, so its application range is relatively limited.

Working Principle

M39003/03-2016/TR tantalum capacitors use the effect of a dielectric layer to store energy. A metal oxide layer is deposited on the anode of the capacitor, and the cathode is connected to a metallic conductor or a semiconductor. By applying a voltage across the two electrodes, an electric field is generated which causes the metal oxide layer on the anode to form an oxide film, forming a barrier between the two electrodes. This barrier determines the capacitance of the capacitor. The other two parameters of the capacitor, leakage current (usually micro amperes) and equivalent series resistance (ESR), are determined by the quality of the oxide film and its thickness.

In addition, the metal oxide layer of the M39003/03-2016/TR capacitor is very delicate and thin, so its capacitance is very sensitive to temperature and electric field. When the operating voltage exceeds the working voltage of the capacitor, the oxide layer will be damaged, and the capacitor will fail immediately. To avoid this situation, it is necessary to stay within the rated voltage of the capacitor and avoid rapid voltage changes when using the capacitor in the circuit.

Conclusion

M39003/03-2016/TR tantalum capacitors have a wide application range and superb working principle. Due to its thin metal oxide layer, it has excellent characteristics of small size, good thermal stability, and high reliability, making it suitable for use in precision circuits and high frequency and high frequency circuits. However, its operating temperature range is also narrower than other types of capacitors, so its application range is relatively limited. Therefore, it is necessary to stay within the rated voltage of the capacitor and avoid rapid voltage changes when using the capacitor in the circuit.
