1. Introduction

Tantalum capacitors, also known as tantalum electrolytic capacitors, are polarized electrolytic capacitors having an anode made of sintered tantalum metal. They are very reliable, and characterized by high capacity/volume ratio, and a wide operating temperature range from -55°C to +125°C, making them suitable for use in thick film hybrid circuits and other applications requiring high capacitance. The M39003/01-2859 is a type of tantalum capacitor, and is suitable for military and aerospace applications requiring high reliability. It is widely used in military and aerospace applications such as aircraft avionic systems, navigation systems, and weapons guidance and control systems.

It has a high-frequency capacitance of at least -20% from1000 kHz to 10MHz and can withstand temperatures up to 125°C. It is available in both radial and axial types and has a tolerance of ±20%.

3. Applications

The M39003/01-2859 is designed for military and aerospace applications, such as aircraft and space flight, navigation systems, weapons guidance and control systems, and communication systems. Its small size and high temperature stability make it suitable for use in thick film hybrid circuits. It is also suitable for use in RF circuits, power supplies, and electronic instrumentation. It is approved for use in a variety of industries, including medical, aviation, automotive, and telecommunications.

4. Working Principle

The working principle of a tantalum capacitor is based on the electrolytic capacitive principle. The anode of the capacitor is made of sintered tantalum powder that is compressed under high temperatures and pressure. This metal is very porous, allowing ions to pass through it when introduced with an electrolyte liquid. This creates an electrical field, forming the capacitor. The capacitor holds a charge and when a voltage is applied across the plates, it stores energy. When a current is applied to the capacitor, it releases energy. The amount of energy stored in a capacitor is determined by the size and capacitance of the capacitor.
