Tantalum capacitors are widely used in modern electrical and electronic products due to their superior properties like high temperature & voltage resistance, long service life, excellent performance, even in noisy environments. The T350B684K050AS is a special kind of surface mount capacitor and it is particularly suitable for use in consumer electronics, low current transfer and as a surge absorber.

The T350B684K050AS is a 470 μF (micro Farad) 6.3 V capacitance with a 1.6 mm maximum body height. It is a polarization capacitor composed of two tantalum electrodes between which a dielectric electrolyte is introduced. The two electrodes are composed of high purity tantalum powder, with the surface coated with a conducting coating such as sintered tungsten. The electrolyte is composed of metallic oxide, such as manganese dioxide, which acts as a “catalyst” to maintain the phase balance, and palladium as a reactant. This unique type of capacitor design reduces its ESR (Equivalent Series Resistance) up to 66 %.

The working principle of the T350B684K050AS is based on the process of charging and discharging. When the capacitor is connected to a power source, a potential difference (Voltage) is created between the two leads which causes an electric field (Electricity) to flow through the electrolyte. When the capacitor is exposed to an AC or DC current, an electric field will be established in the electrolyte and the capacitor will begin to charge up. As the capacitor charges, its capacitance value will increase. Conversely, when the capacitor is disconnected from the power source, the charge on the capacitor will dissipate and the electrolyte equilibrium is restored.

The T350B684K050AS is an ideal capacitor for applications in consumer electronics, low current transfer and as a surge absorber due to its high temperature and voltage resistance, long service life, excellent performance even in noisy environments and low ESR. Furthermore, its construction also impart other advantages like ultra low current leakage, fast recovery characteristics, low inductance and tight tolerance for audio filtering and general rectifying applications. Its combination of high capacitance and low ESR makes it suitable for high frequency switching regulators and low voltage power supplies in telecommunications and defense applications.
