Introduction

Tantalum capacitors are one type of capacitor available. They are constructed from a combination of tantalum and other materials, and vary in capacitance, size, shape, and physical construction. These types of capacitors have some advantages over other capacitor technology, and are used in a variety of applications. In this article, we will discuss the application field and working principle of the TPSC156K035R0450, a specific type of tantalum capacitor.

Application Field

Tantalum capacitors are utilized in a variety of devices and applications, including military and aerospace applications, medical equipment, audio systems, high reliability applications, and more. The TPSC156K035R0450 is a general purpose, miniaturized, standard capacitor suitable for a spectrum of applications, making it incredibly versatile. This specific capacitor is commonly used in high-reliability applications, due to its miniaturization, cost, and durability. It has a maximum working voltage of 25 volts, making it ideal for moderate power levels in applications where space is a critical factor.

Capacitor Construction

The construction of a capacitor refers to the materials and overall structure of the capacitor. In the case of the TPSC156K035R0450, the capacitor is constructed with a metal oxide layer of tantalum, polymer, and electrodes. This metal oxide layer interacts with other components to create the capacitor and also provides insulation and protection to internal components.The capacitor is also embedded in a molded case and sealed with a metal-sealed interface for additional protection. The case material has a zero-halogen content, making it an extremely durable option for mission-critical applications. The construction of the TPSC156K035R0450 consists of an anode, an inner dielectric, an external coating, and a cathode.

Working Principle

At its most basic level, a capacitor works by storing electrical charge and releasing it when needed. This is done by utilizing a dielectric material between two electric conductors. In the case of the TPSC156K035R0450, the inner dielectric material is made up of a tantalum metal oxide layer, which is sandwiched between two electric contacts—the anode and the cathode. When a voltage is applied to the capacitor, the electric contacts create an electrostatic field and the dielectric material separates the two contacts, storing the charges and preventing them from mixing. When the voltage is removed, the battery or other power source is disconnected, and the stored charge in the capacitor can be released to the circuit. This is what allows capacitors to act as filters, which smooth out electrical signals, reduce voltage peaks, and store energy for backup sources.

Conclusion

The TPSC156K035R0450 is a type of tantalum capacitor that is suitable for a wide range of applications and is especially popular for high-reliability applications. Its construction provides insulation and protection, and its miniaturization allows for use in space-constrained projects. The inner dielectric material is made from a tantalum metal oxide layer which reacts to applied voltages and stores electrical charge. When this voltage is removed, the stored charge can be discharged, allowing for functions such as voltage smoothing and energy storage.
