Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor. The “electrolyte” of a tantalum capacitor is a solid manganese dioxide (MnO2) compound. This material is used as the dielectric layer between two electrodes. The anode is made up of sintered tantalum powder and the cathode is made up of a conductive material such as gold, silver or tin.

The use of manganese dioxide as the dielectric material gives tantalum capacitors several advantages over other types of capacitors. These include a high capacitance for their size, high ripple current, low ESR (equivalent series resistance) and very low self-discharge. This makes them ideal for use in power supplies and other high-frequency applications.

173D274X9035UWE3 application field and working principle

173D274X9035UWE3 tantalum capacitors are designed for use in high frequency, high power applications. They have a high voltage rating of 470 Vrms and a low ESR of 0.05 ohms. This makes them ideal for use in switch-mode power supplies, power converters, and other high frequency applications where high performance and reliability are critical.

The working principle of a 173D274X9035UWE3 tantalum capacitor is based on the Faraday law. When a voltage is applied across the capacitor, current flows through the capacitor, causing the capacitance to decrease. This reduction in capacitance is what provides the charging and discharging ability of the capacitor. Thus, a 173D274X9035UWE3 capacitor acts as an energy storage device, releasing energy when the voltage is low and storing energy when the voltage is high.

In addition, the high thermal stability and low ESR of the 173D274X9035UWE3 capacitor makes them suitable for use in high-temperature environments. The high-temperature rating of these capacitors is up to 225°C and the low ESR gives them improved stability when the temperature changes. This makes them ideal for applications that require high reliability, such as in extreme temperatures.

The 173D274X9035UWE3 capacitor also features a low profile and small size, making them suitable for use in space-constrained applications. The low profile of these capacitors also helps reduce the amount of interference and noise generated by the capacitors.

Overall, the 173D274X9035UWE3 tantalum capacitor is designed for applications that require high performance and reliability, such as in power supplies and switch-mode power converters. The low ESR and high thermal stability ensures the capacitors can still perform reliably when subjected to extreme temperature changes, while the low profile and small size helps reduce interference and noise.
