Tantalum Capacitors

Tantalum capacitors are solid state electrolytic capacitors that use a tantalum metal versus aluminum for their anodes. They often have an anode that is surrounded by porous tantalum powder and are connected to a solid electrolyte in an anodically sealed case. Due to their ability to store large amounts of energy, tantalum capacitors are widely used in electronic applications such as computers, phones, radio receivers, television sets, and audio amplifiers.Tantalum capacitors are typically crafted with two conductive plates. On the anode side of the capacitor is the tantalum pellet, which is encased in a dielectric material. The cathode side of the capacitor contains a liquid electrolyte. When a voltage is applied to the capacitor and energy passes through, electrons will accumulate on the anode. By controlling the amount of this electron buildup, the capacitance of the capacitor is adjusted.The size and shape of the anode and cathode will determine the overall capacitance of the capacitor, as well as the maximum voltage it can handle. The size of the pellet anode, the distance between the anode and the cathode, and the type of electrolyte used, all influence the capacitance values. The most common materials used for the anode is tantalum metal, but also other metals like sintered alumina or niobium are used.The model number 173D225X0035WW is a specific model of tantalum capacitor. The “173” in the model number refers to its series designation, and the “D” indicates its case size. The “225” points to its rated capacitance, and the “X” signifies its voltage rating. The “0035” hints to its tolerance, and the “WW” refers to its termination type.The application field for this model of tantalum capacitor is quite broad, as it is designed to be used in various types of high frequency circuits that require stable and high capacitance. They are ideal for small portable devices such as cellular phones, PDAs, portable radios, and other digital and analog circuits. Additionally, they are used in filtering and timing circuits, as well as in integrated circuits.The working principle behind the 173D225X0035WW tantalum capacitor is relatively simple. When connected to a power supply, a positive voltage is applied across the anode and cathode. The electrostatic energy that is created between the anode and the cathode is then stored in the capacitor as an electrical charge. The electrons in the form of an electric current flow across the anode and the cathode, where the voltage is then discharged, resulting in the device functioning as a capacitor.The unique construction of the 173D225X0035WW means that the device can operate at much higher frequencies, temperatures, and voltage ratings than other types of capacitors. The construction of the device also allows for increased capacitance and longer life span, making it an ideal choice for applications that need reliable performance in demanding environments.In conclusion, the 173D225X0035WW is a model of tantalum capacitor that is widely used in devices such as portable electronics, cell phones, PDAs, digital and analog devices, and integrated circuits. Its compact size, reliable performance, and wide voltage range make it an attractive option for many applications. Its working principle is relatively simple and involves the accumulation of electrons on the anode, thus controlling the capacitance values of the device.
