T540D477M004BH8610WAFL is a general purpose, molded surface mount Tantalum - Polymer capacitor that offers high CV per unit volume and low ESL. This device is designed for use in a variety of electronic applications, including portable electronics, cellular phones, and computer peripherals. The T540D477M004BH8610WAFL has a high capacitance range, from 1uF to 470uF, offering flexibility in device selection. This capacitor also offers an operating voltage range of 6.3V - 16V, making it suitable for use in a variety of circuit designs.

The T540D477M004BH8610WAFL is made up of two key components: the structural core and the polymer dielectric. The structural core is comprised of a porous sintered tantalum anode in which a conductive adhesive and cathode ring are encased. The polymer dielectric is a diffusion barrier between the anode and cathode, which allows the capacitor to store energy. This polymer dielectric also creates a gradient of electric dipoles and gives the capacitor its non-polarized nature, allowing it to be used in applications where a non-polarized capacitor is necessary.

The T540D477M004BH8610WAFL is a low-ESR device, making it an excellent choice for eliminating noise and ripple. This capacitor also offers superior high frequency performance and high capacitance stability over temperature and time. Its low ESR, high capacitance, and high frequency performance make this device well-suited for power supply decoupling, logic level power filtering, and stable high frequency timing circuits.

The T540D477M004BH8610WAFL is also well-suited to applications where oxidation is a concern. This capacitor is constructed with a conductive adhesive material and a non-soluble as well as a non-strippable cathode ring. This construction safeguards against failure caused by oxide film formation on voltage-sensing anode surfaces. The use of calcium doping and a diffusion barrier also ensures low ESR and excellent capacitance stability over temperature and time.

The working principle of the T540D477M004BH8610WAFL is based on capacitance. When two conductive surfaces are placed in close proximity, an electrostatic field is created. This electrostatic field then generates a charge that is stored in the dielectric material (polymer in this case) between the conductive surfaces. This stored charge is what creates the capacitance of the capacitor.

In the T540D477M004BH8610WAFL, this charge accumulates on the surface of the anode and is discharged through the polymer dielectric material and the cathode. When AC current is applied to the capacitor, the charge accumulates and releases at a rate proportional to the frequency of the AC current. This cycle of charge accumulation and release is what generates the capacitance of the device.

The T540D477M004BH8610WAFL is a high-performing, reliable Tantalum - Polymer capacitor designed for a wide variety of electronic applications. Its low ESR, high capacitance range, and excellent high frequency performance make this capacitor an excellent choice for eliminating noise and ripple, powering logic level circuits, and stabilizing high frequency timing circuits. It is also designed for use in applications where oxidation can be a concern, as it features a conductive adhesive and a non-strippable cathode ring. Through its combination of features, performance, and reliability, the T540D477M004BH8610WAFL is an excellent choice for a variety of circuit designs.
