Tantalum - Polymer Capacitors

T540D687M003DH8505WAFL is a type of tantalum - polymer capacitor. As one of the most essential components in the electronics industry, these capacitors are used to store electrical charges in a circuit and can filter signals in power supply design. They have a wide range of application including automotive, computer, and telecommunications.

Application Fields

  • Computers. T540D687M003DH8505WAFL capacitors are commonly used in mainboard design and other applications related to data storage and task processing.
  • Telecommunications. Cellular phones, land line phones and other networks are commonly protected with tantalum - polymer capacitors.
  • Automotive. Automotive airbags and electric brakes are mainly controlled by electrical signals, so T540D687M003DH8505WAFL capacitors are often preferred for reliable noise filtering and power supply design.

In addition to the aforementioned applications, T540D687M003DH8505WAFL is frequently used in other fields such as medical equipment, aircraft, military electronics and many more.

Working Principle

Tantalum-polymer capacitors mainly consist of three main components: an anode, a cathode, and an electrolyte. Generally, the capacitance of a capacitor is determined by the size of the anode and the distance between the anode and the cathode. To increase the capacitance, the anode must be made larger and the distance between the anode and the cathode must be reduced. In the case of a T540D687M003DH8505WAFL capacitor, the anode is usually made of tantalum while the cathode is typically made of a carbon material. The electrolyte also plays an important role as it determines the voltage rating of the device.

When a voltage is applied to a tantalum-polymer capacitor, an electrical field is created across the anode and the cathode which causes an electrostatic force to be generated. This force is known as capacitance and it is proportional to the amount of charge stored in the capacitor. The capacitance of the device is directly proportional to its voltage rating as the higher the voltage rating, the more charge it can store.

In addition, the T540D687M003DH8505WAFL capacitor also features a low ESR (Equivalent Series Resistance) which allows it to deliver higher current with less power loss than other types of tantalum-polymer capacitors.

Advantages

  • High Capacitance. T540D687M003DH8505WAFL capacitors have a relatively high capacitance, making them ideal for applications that require large amounts of power.
  • High Voltage Rating. The voltage rating of the T540D687M003DH8505WAFL capacitor is much higher than other types of capacitors, allowing it to withstand higher operating voltages.
  • Low ESR. The low ESR of T540D687M003DH8505WAFL capacitors ensures efficient energy storage and delivery with reduced power loss.
  • High Reliability. These capacitors have a high reliability due to the robustness of their construction and the high quality of the components used.

Overall, the T540D687M003DH8505WAFL capacitor is a versatile component and is widely used in a variety of applications where high capacitance and voltage rating are required. With its high reliability and low ESR, it is the ideal choice for reliable power supply design.
