Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitors which use tantalum as an anode. They are frequently used in aircraft, military, and aerospace applications, as well as in a wide range of consumer electronics. As compared to other electrolytic capacitors, they have a relatively high reliability and a much longer lifetime expectancy. They also have an excellent temperature stability and higher volumetric efficiency.

TAJB336M004SNJ is a 0.33uF, ±20% tolerance, through-hole, SMD-only, voltage-rated tantalum capacitor, specially designed for use in harsh environment. It is especially suitable for use in applications that have either a small footprint or a very tight space for component installation.

The working principle of TAJB336M004SNJ capacitor relies on Faraday\'s law, which states that when a voltage is applied across a capacitor, a corresponding electric field is created between the capacitor\'s plates. This electric field causes a current to flow through the capacitor and deposits the ions from the electrolyte onto the surface of one of the capacitor\'s plates, while liberating electrons from the other plate. This creates a double electric layer between the capacitor\'s plates which acts as a very strong electric insulator.

The basic construction of TAJB336M004SNJ capacitor consists of two layers of dielectric plates, one made of tantalum and another made of niobium. A layer of manganese dioxide is applied to the surface of the tantalum plate, while a layer of conductive polymer is applied on the surface of the niobium plate. These dielectric layers are sandwich between two aluminum foil plates, and the capacitor\'s terminals are connected to them. The capacitor\'s case is attached to one of the aluminum foil plates, which provides electrical insulation and mechanical strength.

Since these capacitors use solid state electrolyte, they are less prone to leakage, shorting, and cap rupture compared to other tantalum capacitors that have liquid electrolytes. They have higher temperature ratings, higher resistance to vibration, and can operate reliably in extended temperature ranges. Their low ESR values also make them ideal for use in applications that require low power dissipation and high ripple current.

In conclusion, TAJB336M004SNJ capacitor is a highly reliable, voltage-rated, solid-electrolyte tantalum capacitor, which is particularly suitable for use in harsh environment. Its high stability and small footprint make it suitable for a wide range of applications that require low power dissipation and high ripple current.
