Tantalum Capacitors

Tantalum capacitors are widely used in modern electronics due to their stability and reliability, and are particularly well suited for applications where high temperature and high-voltage performance are required. The M39003/01-2344H tantalum capacitor is a widely used device for telecommunications, industrial, automotive, computer, and medical applications.

Overview

The M39003/01-2344H is a radial leaded, surface mounted, solid tantalum capacitor with a conductive (MIL-PRF-83401) overcoat, rated for a capacitance of 470µF at 25V, and a temperature range of -55°C to +125°C. It is RoHS compliant, Lead-Free, and Halogen free. The capacitor features an additional hermetic seal, which improves its high-temperature performance and vibration resistance.

Applications

Examples of common applications for the M39003/01-2344H tantalum capacitor include bypass and filtering, timing, bulk storage, energy storage, and decoupling. The capacitor is often used for power supply decoupling stages in large power systems, as it can withstand large ripple currents and supply a rapid output of energy whenever needed. The device is used in both the DCDC converters and in the power factor correction (PFC) systems, and its hermetic seal also provides excellent vibration resistance.

Working Principle

The M39003/01-2344H tantalum capacitor works on the same basic principles as any electrolytic capacitor. The device uses the two metal plates as the two conducting elements, separated by a dielectric material. One plate is connected to a positive terminal, and the other to a negative terminal. When a voltage is applied to the capacitor, the dielectric material produces an electric field between the two terminals. This electric field then accumulates a charge on the plates, which correspond to the capacitance of the capacitor.

Advantages

The most impressive advantage of the M39003/01-2344H tantalum capacitor is their high-temperature stability and reliability. This is due to the hermetically sealed design which is designed to protect the capacitor in extreme conditions. The additional hermetic seal also provides excellent vibration resistance, making it suitable for industrial applications. The 400V rating gives the M39003/01-2344H capacitor a very wide range of potential applications.

Disadvantages

The primary drawback of tantalum capacitors is their poor self-healing characteristics. This means that they are more prone to failure due to short-circuits than other types of capacitors, such as aluminium electrolytic capacitors. The device is also more expensive than other types of capacitors, making it less desirable for cost-sensitive applications.

Conclusion

The M39003/01-2344H tantalum capacitor is a widely used device, and is ideal for applications which require high temperature and high-voltage performance. It is suitable for many applications in telecommunications, industrial, automotive, computer, and medical applications. The hermetic seal improves its high temperature performance and vibration resistance, making it ideal for industrial applications. Despite its poor self-healing characteristics and high cost, the M39003/01-2344H tantalum capacitor is still an excellent choice for many applications.
