Introduction

Tantalum - Polymer Capacitors have been a popular choice for applications that require high-capacity and stable components in an efficient package. The T540D227M006BH8505 is a series of tantalum - polymer capacitors especially designed for high-end applications that require extreme reliability, exceptional performance, and durability.

Technical Specifications

The T540D227M006BH8505 is a 6.3V surface mount capacitor that can range from 0.1µF to 5600µF in capacitance. The rated peak working voltage of these capacitors is 10V, which means that the device can be used in applications requiring higher-voltage operation for a reliable operation. Also, the capacitance tolerance for these capacitors is 5%, making these devices suitable for applications with very strict capacitance tolerances.Another important aspect of the T540D227M006BH8505 is its very high impedance, making them suitable for applications where stray or unwanted inductances or capacitances need to be kept to a minimum. The dielectric strength of these capacitors is rated at 200Vdc and the dissipation factor is rated at 0.15.

Application Field

The T540D227M006BH8505 series of capacitors is used in many different applications, such as automotive electronics, RF communication circuits, LCD backlighting, switching power supplies, and medical electronics. They are also very popular for general-purpose capacitors and can be found in many consumer electronics devices. The device’s high capacitance and low ESR make it ideal for applications that require very stable voltage regulation and high-performance filtering. The capacitors are also very popular in energy storage applications, such as energy harvesting and LED lighting. Due to their excellent electrical characteristics, these capacitors are also used in military and aerospace applications.

Working Principle

The capacitors in the T540D227M006BH8505 series are made with a combination of a tantalum anode and a polymer cathode. The anode is composed of a sintered tantalum powder that is formed into a solid block, while the cathode is made of a sheet of polymer material. The two electrodes are then connected by two conductive layers, an inner layer and an outer layer. The inner layer provides the capacitance between the two electrodes, while the outer layer provides a way for current to flow through the capacitor. When an electrical current is applied to the device, the two electrodes are charged and the capacitance between them is increased, resulting in a change in the voltage. This change in the voltage is what allows the capacitor to store energy and act as a filter for certain frequencies and voltages.

Conclusion

The T540D227M006BH8505 series of tantalum - polymer capacitors is an excellent choice for high-performance applications, due to its high capacitance and low ESR. Their high impedance makes them perfect for applications where stray inductances need to be kept to a minimum, while their high dielectric strength and durability make them suitable for military and aerospace applications. The device can be used in applications such as automotive electronics, RF communication circuits, LCD backlighting, industrial and consumer electronics, energy harvesting, LED lighting, and many more.
