Tantalum capacitors, also known as Ta-caps, are solid electrolytic capacitors consisting of tantalum metal, which acts as an anode, covered by an insulating oxide layer that forms the dielectric and acts as a cathode. The 135D437X9008T2 is a surface mount chip tantalum capacitor designed for general purpose or decoupling applications.

The 135D437X9008T2 chip carries a capacitance of 4.7µF, a voltage rating of 10 volts, and a tolerance of ±20%. This capacitor’s chip size is 0.127" x 0.063" x 0.063", making it well-suited for a range of applications that require low-profile capacitors such as mobile phones and similar handheld devices, laptop computers, automotive subsystems, and other circuit boards and PCBs where space-constrained components are necessary.

The 135D437X9008T2 offers excellent performance characteristics, including low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) when compared to other types of capacitors of equivalent size and capacitance. The capacitor also offers superior temperature stability and pulse handling capability. Its stand-out performance characteristics make the 135D437X9008T2 ideal for applications that require a steady, reliable source of power, such as in instrumentation or power supplies.

From a working principle standpoint, the 135D437X9008T2 operates similarly to other types of capacitors. In direct current (DC) circuits where a periodic or continuously varying voltage is applied to the capacitor, a corresponding electric field is generated within the dielectric (insulating oxide layer) that causes displacement of electrons within the material, resulting in a storage of electrical charge on the capacitor\'s plates. The stored charge on the capacitor\'s plates forms an electric field that draws a current through the circuit and effectively blocks any additional current.

The effectiveness of a tantalum capacitor, and of the 135D437X9008T2 in particular, is dependent upon the quality of the electrolytic dielectric. This is achieved through the stringent manufacturing processes employed by the manufacturer, which includes chemical etching of the dielectric, thorough impregnation of the dielectric with a high-purity conductive solution, and then an annealing process. This annealing process effectively prevents corrosion of the dielectric, ensures electrical properties are maintained, and improves the reliability of the capacitor.

The 135D437X9008T2 is an excellent choice for a variety of applications which require a reliable, low-profile component for their power and instrumentation needs. The 135D437X9008T2’s impressive performance characteristics, space-constrained size, and its high-quality construction make it an ideal choice for manufacturers and engineers who are looking for a top-of-the-line tantalum capacitor.
