Tantalum Capacitors

M39006/09-8586 Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors, are electrical components that use a form of oxide film as the dielectric layer. The basic configuration of such capacitors consists of two metal plates, typically made of tantalum metal, separated by a thin oxide film. They are extensively used in many electronic systems such as in TV, DVD and CD players, among other applications. The M39006/09-8586 series of capacitors is a type of tantalum capacitors.

The M39006/09-8586 caps are particularly well-suited for use in military applications where high-reliability, long-term performance, and vibration resistance is critical. These capacitors are built conformal-coated to provide increased protection against environmental factors such as temperature and humidity extremes. They also have a wide operating temperature range of -55°C to +125°C; this is much wider than what is found with other types of capacitors.

The principle of operation for M39006/09-8586 capacitors is based on the dielectric breakdown of a thin oxide film mechanism, which occurs when electric charges are applied to the two metal plates. This process produces a strong, stable electrostatic field that stores and redistributes the charge applied across the two plates. The capacitance of the M39006/09-8586 series is much higher than that of conventional capacitors because of its dielectric layer and higher breakdown voltage.

In terms of application fields, the M39006/09-8586 capacitors are designed for use in circuits where low leakage current, low axial displacement, and low temperature rise are of major importance. These caps can be used in a wide range of applications, such as: high-voltage power supplies, switching power supplies, audio devices, medical equipment, computer systems, military instrumentation, and telecommunications systems.

In conclusion, M39006/09-8586 capacitors offer superior performance compared to other types of capacitors, due to their high dielectric constant, stability, and wide temperature range. They have been designed specifically for use in military applications where high-reliability, long-term performance, and considerable vibration resistance are critical.
