Tantalum-Polymer Capacitors are a type of capacitor typically used for various applications including in laptop computers, circuits, memory modules and automotive systems. The T540B686M004BH85107280 is a radial design capacitors constructed with an anode sheet fabricated from a tantalum coated with a conductive polymer, an insulation layer and a cathode sheet. This type of capacitor provides low-leakage, high-dielectric strength, high-voltage tolerance and low ESR due to its special construction.

The T540B686M004BH85107280 is a low-profile, radial-style tantalum – polymer capacitors ideal for applications that require low-profile, high-CV capacitance values in limited volume. It is specifically designed for use in computer motherboards, memory modules, LCD backplanes and automotive systems. Its size is 5.4mm L x 6.86mm W x 4.8 mmH, which makes it fit in a variety of limited space applications. With capacitance from 680nF to 10uF and a voltage rating up to 10V, the T540B686M004BH85107280 can meet the needs of almost any electronic systems.

The working principle behind the T540B686M004BH85107280 is explained below:

In its basic form, the T540B686M004BH85107280 contains two metal plates (the cathode and anode sheets) which are separated by a thin insulating layer. When a voltage is applied across the plates, a current flows through enabling charge to be stored in the capacitor. This stored energy allows a further voltage to be retained across the terminals of the capacitor which can be used to power the circuits in the device. The main advantage of the T540B686M004BH85107280 is that it is capable of retaining its charge for a much longer period than traditional electrolytic capacitors, due to the thin insulation layer and the polymer used in the capacitor.

The T540B686M004BH85107280 are very reliable and capable of operating at high temperatures. It also features a very low equivalent series resistance (ESR), which provides good-low frequency performance and low self-inductance. Additionally, their thin, lightweight construction allows them to be placed in tight locations, while the polymer layer provides an improved dielectric strength which offers better electrical insulation and prevents unexpected capacitance loss.

In summary, the T540B686M004BH85107280 is an ideal type of capacitor for limited space applications, as it provides very low-profile, high-CV capacitance values and low ESR in a very small form factor. The electrolytic-polymer design of the T540B686M004BH85107280 offers superior dielectric strength, allowing it to be used in a variety of high temperature, high frequency, and harsh environment applications. This type of capacitor is perfect for applications requiring strong electrical insulation, low leakage and low-losses, and is therefore very suitable for use in laptop and memory modules, in automotive systems, as well as in LCD backplanes.
