Tantalum capacitors are amongst the most popular electronic components used today. They are widely used for circuit protection, voltage regulation, measurement and other functions within various types of embedded systems. The M39003/01-8055/HSD is a popular type of tantalum capacitor that has emerged as a preferred choice for use in a range of applications. This article will discuss the application fields and working principle of this capacitor.

Applications of the M39003/01-8055/HSD Capacitor

The M39003/01-8055/HSD uses a tantalum dielectric material which makes it ideal for use in various electrical and electronic applications. Its anisotropic properties make it effective for use in low noise circuits, voltage regulation, motion controller protection, and energy harvesting applications. This capacitor is particularly suitable for use in high-voltage circuits and embedded systems as it has an extremely low effective series inductance (ESL). Additionally, this type of capacitor is often used in the telecommunications industry for signal filtering, power supply filtering, and supply line conditioning.

Another application area for this capacitor type is automotive electronics. Its low ESR and long-term stability make it a great choice for use in the voltage regulation of batteries. Additionally, it can be used in the protection of airbag inflators, power steering systems, and brake systems, amongst other things. In industrial settings, the M39003/01-8055/HSD capacitor is often used in industrial control systems, motors, audio equipment, and instruments.

Working Principle of the M39003/01-8055/HSD Capacitor

The M39003/01-8055/HSD capacitor utilises a metalised eutectic (metallised) tantalum oxide dielectric. This is an anisotropic material that has a high dielectric constant and low effective series inductance, making it popular for use in high-reliability and high-voltage circuits. It can store a large amount of charge in a small volume - up to 17.5μF in 2.5mm² - making it well suited for compact and space-constrained applications. In addition, its low equivalent series resistance (ESR) and long-term stability are great for use in automotive and industrial applications.

The internal layout of the M39003/01-8055/HSD capacitor is designed to make the most of these anisotropic properties. It uses a metal cage that surrounds the capacitance dielectric material. This metal cage serves the purpose of both protecting the capacitance dielectric material from external interference and also helping to shape the capacitance characteristics. The capacitance characteristics of the M39003/01-8055/HSD capacitor are further improved by having a unique termination process that connects the internal metal cage to the external metal shell.

Conclusion

The M39003/01-8055/HSD is a popular type of tantalum capacitor due to its anisotropic properties, low ESR and long-term stability. Its design and construction make it suitable for use in a wide range of applications, from high-voltage systems to industrial control systems. Its metalised tantalum oxide dielectric and metal cage support the stable and reliable performance of the capacitor in nearly any application. Whether used for signal filtering or voltage regulation, or as a protection component, this type of tantalum capacitor has proven its worth in many different domains.
