Tantalum capacitors are polarized capacitors that are used extensively in all kinds of electronic applications. They are also referred to by the designation F931A476KAA and are used in many applications. In this article, we will discuss the application fields and working principle of the F931A476KAA, which is an important selection criterion when selecting an appropriate capacitor.

First, we must familiarize ourselves with the parameters of the F931A476KAA. This capacitor is a polarized tantalum chip capacitor, which means it is constructed using two distinct metallized surfaces, one of which is a dielectric while the other is a metallic conductor. The F931A476KAA is rated at a voltage of 25 Volts DC and has a capacitance of 47µF. The temperature range for this capacitor ranges from -55°C to +85°C and its pulse load rating is 2A. The static dissipated power is 4.5 mW.

The application fields of the F931A476KAA include power supplies, DC/DC converters, chip on board technology, switch mode power supply (SMPS) applications and energy storage devices such as batteries. The F931A476KAA can also be used for RF (Radio Frequency) applications such as antenna matching circuits. It is also used in high frequency circuit design such as in voltage-controlled oscillators (VCOs). Additionally, it is used in low-pass, high-pass and band-pass filtering networks.

The working principle of the F931A476KAA is based on the principle of electrochemical double layer capacitance (EDLC). The F931A476KAA is constructed from a material composed of a tantalum powder with a metallic coating. This combination of the powder and the metallic coating results in the formation of an electrochemical double layer at the interface between the two components. The structure of the EDLC results in a high Coulomb/Farad (C/F) ratio. This high C/F ratio results in excellent performance characteristics such as low equivalent series resistance (ESR), low equivalent series inductance (ESI), low dielectric absorption, and large capacitance.

The performance of the F931A476KAA is further enhanced by its unique ESR technology. This technology allows the capacitor to maintain a very low ESR while it is operating under large temperature swings. This makes the F931A476KAA ideal for pulse loading applications and high frequency circuit designs where large temperature swings are present. The F931A476KAA also offers excellent charge/discharge characteristics, as well as an extended capacitance frequency response.

In conclusion, the F931A476KAA is a highly reliable and versatile polarized tantalum capacitor. It is primarily used in power supplies, DC/DC converters, chip on board technologies, switch mode power supply (SMPS) applications, and energy storage devices such as batteries. Additionally, it is useful for RF applications, high frequency circuit design, and voltage-controlled oscillators (VCOs). The F931A476KAA is constructed from a material composed of a tantalum powder with a metallic coating, which allows it to maintain a very low ESR while operating under large temperature swings. Its unique ESR technology also enhances its performance by providing excellent charge/discharge characteristics, as well as an extended capacitance frequency response.
