Tantalum capacitors occupy a unique position among all available types of capacitors. They are characterized by high dielectric strength, low internal resistance, good reliability, low leakage, long life expectancy, and low parasitics. The M39003/01-5246 is a type of tantalum capacitor that is widely used in many applications. This article will explore the application field and working principle of this capacitor.

M39003/01-5246 Application Field

The M39003/01-5246 is a general-purpose type tantalum capacitor with a wide range of applications. They are available in two main configurations: an axial leaded case and a surface mount version.

The axial leaded version is commonly used in applications with power supplies and DC/DC converters. They are also often used for filtering or smoothing circuits, voltage regulators, and oscillators. The small size and low cost of this type make it well-suited for use in portable devices, mobile phones, and laptop computers.

The surface mount version is usually used for high frequency applications, such as RF circuits and high speed switches. This type of capacitor is also ideal for signal processing and filtering in industrial, automotive, and military applications.

M39003/01-5246 Working Principle

Tantalum capacitors work on the principle of electrochemical capacitance. The capacitor consists of two metallic plates separated by an insulating material. This insulating material is also referred to as the dielectric. When a voltage is applied between the two plates, an electric field is created, and this electric field creates an electrostatic attraction between the two plates. This electrostatic attraction is what holds the charge in the capacitor.

The M39003/01-5246 capacitor is constructed with a titanium pentoxide (TiO2) dielectric. Titanium pentoxide has a very high dielectric constant and provides excellent stability and performance for high frequency applications. The capacitor is also encapsulated in an inert epoxy resin that provides anti-oxidation protection. The construction of the M39003/01-5246 makes it well-suited for use in harsh environments where temperature, humidity, and mechanical stresses are all present.

Conclusion

The M39003/01-5246 is a type of tantalum capacitor that offers a wide range of applications in both axial and surface mount configurations. Its construction with titanium pentoxide dielectric makes it ideal for high frequency applications, and its encapsulating epoxy resin ensures protection against oxidation. This capacitor is well-suited for use in many different types of applications that require reliable performance and long life expectancy.
