Key Specifications:

• Capacitance: 4700µF

  • The 4700µF capacitance provides significant energy storage, which is essential for applications requiring large amounts of charge/discharge cycles. This large capacitance ensures effective filtering of power supply ripple and helps maintain stable voltage levels in circuits with fluctuating power demands.

• Voltage Rating: 50V

  • The 50V voltage rating indicates that this capacitor can safely handle voltages up to 50V, making it ideal for circuits that operate at moderate to high voltage levels. It provides reliable performance in power supplies, voltage regulators, and energy storage systems where voltages can fluctuate.

• Dimensions: 18mm (diameter) x 40mm (length)

  • The 18X40mm size allows this capacitor to provide a high capacitance in a slightly larger package, making it suitable for circuits that need higher energy storage and voltage tolerance. The extra length allows for additional internal capacitance and charge storage.

• Mounting Type: Through-hole

  • The through-hole design allows this capacitor to be securely mounted onto printed circuit boards (PCBs), providing robust mechanical and electrical connections. This type of mounting is ideal for mass production and prototyping.

Applications:

• Power Supply Filtering:
  This capacitor is excellent for smoothing the rectified DC output in power supplies by reducing ripple and ensuring stable, clean DC voltage. It is commonly used in high-power circuits where voltage fluctuations must be minimized to protect sensitive components.

• Decoupling and Bypass:
  The 4700µF 50V capacitor helps in filtering out high-frequency noise and transients from the power supply, ensuring that sensitive components such as microcontrollers, audio systems, and other analog circuits receive a stable and clean voltage.

• Energy Storage:
  With its large 4700µF capacitance, this capacitor can store substantial amounts of energy, making it ideal for applications where energy storage is required, such as in UPS (Uninterruptible Power Supply) systems, battery charging circuits, and systems that need to store energy temporarily for later use.

• Smoothing Rectified Voltage:
  In AC-to-DC conversion circuits, this capacitor smooths out the ripple from the rectified signal, providing a cleaner and more stable DC output. It is particularly useful in power supply designs for computers, industrial equipment, and other high-voltage systems.

• Signal Filtering:
  It can be used in filtering applications to ensure that signals are free from power supply noise or interference. The large capacitance ensures effective removal of low-frequency ripple, ensuring smooth and noise-free operation of sensitive circuits.

Physical Characteristics:

• Size:
  The 18mm diameter and 40mm length provide a substantial energy storage capacity in a relatively compact form, suitable for high-power applications where space is available for slightly larger components.

• Construction:
  This is an aluminum electrolytic capacitor, a type that is well-known for its high capacitance-to-volume ratio. It is a polarized component, meaning it must be installed with the correct polarity: the longer lead is the positive (anode) terminal, and the shorter lead is the negative (cathode) terminal.

• Lead Type:
  The through-hole mounting ensures that the capacitor can be easily soldered onto a PCB, providing a reliable mechanical and electrical connection. The through-hole design is widely used in both prototyping and mass production environments.

Summary:
The 4700µF 50V 18X40mm Through Hole Electrolytic Capacitor is a high-capacity, high-voltage component ideal for applications that require substantial energy storage, filtering, and voltage stabilization. With its 4700µF capacitance, 50V voltage rating, and through-hole mounting, this capacitor is perfect for power supplies, decoupling, and energy storage systems. The 18X40mm size offers a balance of high capacitance and physical size, making it suitable for a wide range of high-power electronic circuits. This capacitor ensures reliable performance in demanding applications where high capacitance and voltage tolerance are essential for maintaining stable, clean power delivery.
