Tantalum capacitors, also known as tantalum electrolytic capacitors, are polarized electrochemical capacitors which use tantalum as an electrode with an oxide layer as a dielectric. This type of capacitor is notable for its low volume, low value, and high capacitance, making it particularly well-suited for applications where large values of capacitance are needed in a limited space. The F981A225MMA is a tantalum polymer capacitor, the first of its kind, which utilizes a solid organic polymer as the electrolyte. This allows for a much larger surface area to be used for the capacitor, increasing the amount of capacitance and decreasing the size of the capacitor at the same time. It also offers some improvements in reliability and performance, making it an attractive choice for many applications.The F981A225MMA is most often used in electronic circuits where a large amount of capacitance is required in a limited space. This can include audio amplifiers, voltage regulators, power supplies, computer motherboards, and telecommunications equipment. The capacitor is also frequently found in mobile phones and other handheld devices, where its low capacitance and small size make it an ideal choice.As a polarized capacitor, the F981A225MMA has two terminals, one of which is labeled “+” and the other is labeled “-”. The “+” terminal should be connected to the positive voltage source, while the “-” terminal should be connected to ground. The voltage applied to the capacitor should not exceed its rated voltage, which is 18 VDC for the F981A225MMA.The working principle of a tantalum capacitor is based on the storage of electrical charge in an electrolyte. When an applied voltage is applied across the capacitor, an electric field is created which causes ions of the electrolyte to move from one electrode to the other, forming a layer of charge on each of the electrodes. The amount of charge stored is proportional to the applied voltage, and the capacitance of the capacitor is determined by the surface area of the electrodes as well as the type of electrolyte.The F981A225MMA is a reliable and efficient capacitor, making it an ideal choice for almost any application where a large amount of capacitance is needed in a limited space. Its ability to withstand high temperatures makes it especially suitable for use in high-heat environments, such as on computer motherboards, and its low value makes it well-suited for applications where cost is a major factor. With its many advantages, the F981A225MMA is likely to continue to be a popular choice among electronics designers for many years to come.
