T520D107M010ATE018 Introduction

If you’re looking for a capacitor that is efficient in terms of space, has consistent electrical performance, is reliable, and lasts a long time, then T55D107M010C0018 tantalum electrolytic capacitors are a great option. Solid tantalum capacitors are a great option for surface-mount assembly technology because they have excellent stability and can withstand high temperatures. This is due to the tantalum, tantalum oxide, or manganese dioxide systems they are made of. Vishay Sprague is a company that has been at the forefront of the industry and has been leading the way in producing a wide range of tantalum capacitors for various electronic applications. These capacitors are used in consumer electronics, industrial equipment, automobiles, military devices, and aerospace technology.

Tantalum isn’t typically found in its pure form. It’s actually quite common to find it in various oxide minerals, usually in conjunction with columbium ore. When the contents of this combination are more than one-half tantalum, it is commonly referred to as “tantalite”. Tantalite is mainly sourced from countries like Australia, Brazil, Canada, China, and some African nations.

Did you know that synthetic tantalite concentrates made from tin slags in countries like Thailand, Malaysia, and Brazil are used as a major source of raw material for producing tantalum? Did you know that most of the world’s tantalum production is used in electronic applications, especially capacitors? Tantalum has a lot of important uses, such as making cutting tools with tantalum carbide, creating high-temperature superalloys, producing chemical processing equipment, making medical implants, and developing military ordnance. Vishay Sprague uses tantalum materials in various forms, such as powder, wire, rod, and sheet, for different purposes. These materials are primarily used for capacitor elements and high-temperature vacuum processing.

The Basics of Tantalum Capacitors

Did you know that many metals tend to form non-protective crystalline oxides? For instance, iron rusts, and copper forms black oxide. Some metals have the ability to create oxides that are dense, stable, and tightly adhering, which also act as electrical insulators. These metals are commonly referred to as “valve” metals, and they consist of tantalum, titanium, niobium, hafnium, zirconium, and aluminum. There are only a few of these that allow for precise control of oxide thickness through electrochemical methods. Out of all the materials, aluminum and tantalum are the most valuable for the electronics industry. Capacitors are an essential component in a wide range of electrical devices, including radios, TVs, missile controls, and car ignitions.

The purpose of these is to hold onto an electrical charge that can be used at a later time. Capacitors are made up of two metal plates that conduct electricity. Basically, there’s a material in between them that doesn’t conduct electricity. Tantalum pentoxide is the dielectric material used in all tantalum electrolytic capacitors. Tantalum pentoxide is a compound that has a strong ability to store electrical energy and a high capacity to store electrical charge.

When capacitors are made, they apply a layer of tantalum pentoxide to their electrodes using an electrolytic process. When the film is applied, it comes in different thicknesses and is applied at different voltages. At first, it’s transparent, but as light passes through it, it takes on different colors. You’ll notice this coloring on the tantalum electrodes of all kinds of tantalum capacitors.

When it comes to comparing ratings, tantalum capacitors usually have a capacitance/volume efficiency that’s up to three times better than aluminum electrolytic capacitors. You can get an idea of how efficient other types of capacitors are in terms of capacitance per volume by looking at this table. It lists the different materials used in each type of capacitor and their corresponding dielectric constant ranges.

Just so you know, the dielectric constant of tantalum pentoxide is 26, which is about three times higher than the dielectric constant of aluminum oxide. It’s worth noting that the tantalum capacitor is really good at providing a lot of microfarads per unit volume. This is partly because the electrolytic process used to make it can create very thin films. Basically, the capacitance of a capacitor depends on a few things: the size of the plates inside it, how far apart those plates are, and the type of material between them.

Solid electrolyte polymer tantalum capacitors

Pieces of powdered tantalum are used as the anodes in solid electrolyte polymer capacitors. On the entire surface of the anode, a dielectric layer made of tantalum pentoxide is formed. The anode is then coated with a highly conductive polymer to form the cathode system. After applying the electrical polymer layer, we add a layer of graphite and then top it off with a layer of metallic silver. This creates a conductive surface between the capacitor element and the outer terminal (a lead frame or something else).

Plastic resins, such as epoxy, surround the element in a molded chip polymer tantalum capacitor. The molding material has been chosen to meet the requirements of UL 94 V-0 and ASTM E-595 for outgassing. After being put together, the capacitors are tried and inspected to make sure they will last a long time and work well. It can be used in a wide range of electronic products because it is very stable and reliable. Using a conductive polymer cathode system gives the capacitors a very low equivalent series resistance (ESR), which makes them great for high-frequency uses.

T520D107M010ATE018 Applications

The T520D107M010ATE018 capacitor can be used for many things, such as:

  • Power Supply Filtering: Because it has a high capacitance and a low ESR, it filters and smooths out voltage changes in power supply circuits.
  • Audio Amplifiers: This capacitor is used to condition the signal in audio amplification circuits. Its low ESR and small size keep the sound quality high.
  • Battery-Powered Devices: It keeps the voltage levels stable and makes movable electronics and IoT devices use less power.
  • DC-DC Converters: Its low ESR makes it possible for DC-DC converters to change energy efficiently and keep output voltages fixed.
  • Industrial Control Systems: It is reliable and stable in harsh industrial settings, so it can be used in motor drives and automation equipment.
  • LED Lighting: This capacitor makes sure that LED lighting applications have a stable power source and consistent lighting.
  • Communication Equipment: It helps make sure that power is distributed evenly and that telecommunication and networking devices can talk to each other reliably.
  • Automotive Electronics: Because it can handle rough conditions, it is used in ECUs and entertainment systems in cars.

The capacitor is perfect for these uses because of its high capacitance, low ESR, small size, and voltage rating. This improves performance and reliability.
