Tantalum capacitors are widely used in a variety of electronic device applications. M39003/01-5368A is one of the most popular models in the tantalum capacitor industry. This article will introduce its application field and working principle.

The M39003/01-5368A belongs to the SMD type of tantalum capacitor. It is an electrolytic capacitor with polarity and features low Equivalent Series Resistance (ESR). Depending on the ratio of their capacitance and ESR, tantalum capacitors are divided into three categories: general-purpose, low-ESR, and high-capacitance. The M39003/01-5368A falls within the range of general-purpose capacitors.

This capacitor is characterized by its maximum capacitance of 10µF, cased in a miniature size with a diameter of 4.5mm and a height of 1.0mm. It has a maximum working voltage of 6.3V and a nominal temperature range of -55ºC to +105ºC. Since it has a relatively low capacitance and a small size, the M39003/01-5368A capacitor is suitable for analog and digital circuits of 10V or lower. Examples of its applications include timing, filtering, AC coupling, and memory backup.

The working principle of the M39003/01-5368A revolves around its anode and cathode. The anode is typically made of sintered tantalum powder and is formed in a cylindrical shape. On the other hand, the cathode is a solid manganese dioxide which is held against the anode using conductive leads made of metal or alloys. When power is applied to the capacitor, an anodic growth is formed on the surface of the anode. This anodic growth forms the dielectric, allowing electric energy to be stored in the capacitor.

The M39003/01-5368A is one of the most popular tantalum capacitors available in the market today. It is an ideal choice for 10V or lower analog and digital circuits due to its small size and low capacitance. Moreover, its low ESR and broad temperature range make it ideal for a wide variety of applications from timing to memory backup.
