Tantalum-polymer capacitors, also called tantalum-ionic capacitors, are a type of electrical component used in a wide variety of applications. Made up of layers of tantalum and a polymer dielectric, these capacitors offer a number of advantages compared to traditional ceramic or electrolytic capacitors. The T540D687M2R5BH8605 is a powerful component that provides significant advantages in a variety of circuits.

The T540D687M2R5BH8605 is commonly used in RF and microwave applications, due to its low ESR (Equivalent Series Resistance) and high frequency response. It’s also used in power supply circuits, including voltage conversion, voltage Regulator Module, and Type C LED power driver. They are capable of reliable operation in high temperature and high vibration environments. In battery-powered applications, these capacitors help reduce current draw and power consumption, offering greater efficiency. They are often used in consumer electronics, automotive applications, UPS systems, digital amplifiers, and wearable devices.

The T540D687M2R5BH8605 is a through-hole component which operates at a maximum DC voltage of 100V. It has an operating capacitance of 680 to 690μF, with a tolerance of ±20%. Its charge/discharge time is 2.5 milliseconds (ms). The component is light and thin, with dimensions of 25.4 by 10.3mm, and a height of 3.5mm. It has a low ESR value of 0.02 ohms, and a low leakage current of 0.1 to 0.2 microamps (μA).

The T540D687M2R5BH8605 operates on the basic principles of capacitor operation. In a capacitor, charges of equal magnitude but opposite sign build up on two separate conducting plates, and between them is a non-conductor or dielectric such as tantalum or polymer. When a voltage difference is applied to the two conductor plates, the charges on each opposing plate migrate toward other sides of the dielectric. This causes a charge separation and stores energy in the capacitor.

The T540D687M2R5BH8605 is ideal for high frequency applications due to its low ESR value, high frequency response, and small size. Its low leakage current also makes it well suited for battery-powered applications, where current draw needs to be reduced. The component’s high tolerance and low ESR also make it reliable in high vibration and temperature environments. The component is also relatively inexpensive, making it an economical choice for a wide range of applications.
