Tantalum Capacitors

Tantalum capacitors, also known as electrolytic capacitors, are capacitors that use a tantalum anode and a cathode filled with liquid electrolyte that acts as a separation between anode and cathode.When a potential difference is applied across the two electrodes, an electric field is created resulting in the accumulation of charge in the anode, which in turn increases the capacitance of the device.The amount of chargethat the capacitor can store is determined by its capacitance, which is directly correlated to the thickness of the tantalum anode and the area of the electrode plate.Tantalum capacitors are typically used in high-voltage circuit applications, due in part to their higher capacitance-to-size ratio, as well as being less prone to damage from transientvoltage surges.

T495B226M010ATA2K3 application field and working principle

The T495B226M010ATA2K3 is a low-cost, high-density, high-temperature, surface-mount capacitor with a capacitance of 22µF (microfarads). The capacitance of the capacitor is measured at 10V and higher, so it is suitable for use in circuits operating at higher voltages, including automotive and industrial applications. Due to its high-temperature capability and its ultra-low ESR (equivalent series resistance) of 0.15 Ω, it is also suitable for use as a buffer capacitor in circuits requiring high power dissipation. The T495B226M010ATA2K3 also has high dielectric absorption and electrical strength, high insulation resistance, good solderability, and excellent aging characteristics making it an ideal solution for circuits requiring reliable performance and reliability.

The T495B226M010ATA2K3 has an anode made from tantalum, a metal with a high melting point, strong corrosion-resistance, and good thermal stability. To provide the highest possible capacitance density, the tantalum anode is etched with a highly conductive, low-loss, non-reactive layer of material, typically niobium pentoxide. The other electrode is an aluminum and tantalum fire-leakage capacitor, or “AlTant” capacitor, which is usually enclosed in an epoxy case. With an AlTant capacitor, an electric potential is created between the two electrodes, resulting in an electro-chemical reaction that produces a static charge. This static charge builds up inside the capacitor at a rate determined by its capacitance until the potential reaches the rated operating voltage level, at which point the capacitor is said to be fully charged.

The T495B226M010ATA2K3 achieves an excellent capacitance-to-size ratio, allowing for its use in high power, high voltage, and high temperature applications. Additionally, its low ESR and high insulation resistance make it suitable for a range of automotive and industrial applications. The capacitor is highly reliable over a wide temperature range and is RoHS compliant, making it an excellent choice for most capacitor needs.
