Tantalum capacitors are electrolytic capacitors that use tantalum metal for the anode and an oxide cathode. These capacitors are widely used for their high capacitance, low equivalent series resistance (ESR), and small size. M39003/01-2294H, a surface-mount tantalum capacitor, is designed for use in demanding applications such as aircraft and military systems. This article will discuss the application field and working principle of M39003/01-2294H.

Application Field of M39003/01-2294H

The M39003/01-2294H capacitor is primarily used in military, aerospace, and high-end audio applications. These devices are reliable in extreme temperatures and offer high capacitance and low ESR. They are small and flexible and thus ideal for high-density PCBs.

M39003/01-2294H capacitors are often used in aircraft, military, and space systems, such as missile guidance systems, radar systems, and communication systems. These systems often require extreme reliability and high performance, which the M39003/01-2294H capacitor is able to provide.

Working Principle of M39003/01-2294H

M39003/01-2294H capacitors are based on a tantalum and an electrolytic system. To fabricate these capacitors, tantalum powder, pressed into a die element, is anodized in acid electrolyte in order to form a porous tantalum oxide layer. The oxide layer acts as the dielectric. The capacitor is completed by attaching a conducting material (tin foil or copper foil) to the anode and connecting it to the cathode using a lead wire.

M39003/01-2294H capacitors are polarity sensitive meaning that the positive lead should be connected to the anode and the negative lead should be connected to the cathode. When voltage is applied to the capacitor, electrons are gradually transferred between the anode and the cathode, filling up the tantulum oxide layer to form an electrochemical layer. This process is called “charging”. The charge is then stored in the electrochemical layer allowing current to flow through it.

Conclusion

M39003/01-2294H is an ultra-stable tantalum capacitor designed for high-end applications such as aircraft and military systems. It is highly resilient and has excellent performance. Its small size and low ESR makes it ideal for use on high-density Printed Circuit Boards. The capacitor is made using a tantalum and electrolytic system, where a tantalum layer is anodized for the dielectric layer. The capacitor is polarity sensitive and the charge is stored in the electrochemical layer after charging.
