Tantalum capacitors are a type of electrolytic capacitor, which utilizes the anodic oxidation of the tantalum metal, forming an electrochemical capacitor. This type of capacitor is known for its low dielectric absorption, high volumetric efficiency, as well as being highly stable over a wide temperature range. As such, they are widely used in a variety of electronic applications, from power supplies and interfacing circuits to medical equipment and consumer electronics. The code 109D477X9030T2 indicates a particular type of tantalum capacitor.

The design of the capacitor begins with a pellet or anode of sintered tantalum, which is then vacuum sealed in a plastic protective jacket. The upper part of the anode is coated with a thin protective insulating film, making it non-conductive. A thin layer of manganese dioxide (MnO2) is then carefully painted onto the anode and connected to the capacitor’s outer casing. When connected to a power source, this creates a capacitor with a specific capacitance.

The 109D477X9030T2 is a surface mount, multi-layer SMT capacitor, meaning it can be applied directly to a printed circuit board without the need for additional mounting hardware. It is multilayer for increased volumetric efficiency, making it small enough to fit onto a single printed circuit board. The MnO2 electrolyte allows the capacitor to have a high capacitance of 4.7 µF, which is necessary for high power applications such as DC/DC converters or power supplies. This type of electrolytic capacitor is also known for its high ESR (Equivalent Series Resistance), which helps to suppress high frequency noise which could otherwise interfere with the circuit. Despite its small size and low voltage rating (6V), this capacitor is capable of handling large amounts of ripple current.

Due to its stability over wide temperature ranges and good volumetric efficiency, the 109D477X9030T2 is popular in a variety of applications, including automotive systems, industrial automation, communication systems, medical equipment and consumer electronics. It can be used in high frequency switching supplies, fuel-cell chargers, computer motherboards, touch controllers and many other applications. It is also widely used in military applications, as its stability and longevity make it a reliable choice for a variety of applications. As such, this type of capacitor is a popular choice for a variety of devices and systems.

The 109D477X9030T2 is a type of multi-layer electrolytic capacitor, which makes use of the anodic oxidation of tantalum metal and the MnO2 electrolyte to provide high capacitance in a small form factor. Due to its stability and reliability over a wide temperature range, it is widely used in a variety of applications, from power supplies and interfacing circuits to automotive systems, industrial automation, medical equipment and consumer electronics. In addition, its high ESR helps to reduce noise, making it a great choice for many circuits and devices.
