UFW1A333MRD

Aluminum electrolytic capacitors are passive devices that store electrical energy in the form of electrical charge. They are composed of two conductive plates; one plate is covered with an oxide material that acts as the dielectric insulator between the two plates. A current, typically a direct current, is applied to the electrode on the dielectric material, which enhances the storage capacity of the aluminum electrolytic capacitor. The UFW1A333MRD, in particular, is a capacitor designed to operate in the highest temperature range of any Al- electrolytic capacitor, with a wide -40 ~ +105 degree Celsius operating temperature range.

The UFW1A333MRD, a 265V DC Aluminum Electrolytic Capacitor with radial Lead, is designed to meet the requirements of industrial electronic systems, power supplies, HID lighting, and high frequency applications. It has a cylindrical shape with non-magnetic construction and features surge current resistance, self-healing, and high reliability. This capacitor utilizes a double-sided design, making it both reliable and flexible for applications where space constraints require it to fit in tight locations. The high operating temperature of up to 105°C makes it more suitable for applications where higher temperature-resistance is required.

The UFW1A333MRD utilizes a drawing process for the electrodes. This superior manufacturing method offers superior products with superior electrical characteristics and superior dissipation of heat. The benefit of this design is that it can reduce the component’s equivalent series resistance (ESR) and equivalent series inductance (ESL). This helps the capacitor to operate with higher surge current resistance and more stable operation as temperature changes.

The UFW1A333MRD has a working principle based on Faraday\'s law of electrolytic action. This law states that when a current is applied between the two electrodes, electrolyte molecules are pushed along the plates and a voltage is created. The voltage across the capacitor is determined by the quantity of electrolyte molecules moving between the plates. The increased number of electrolyte molecules creates an increased amount of space between the plates, which forms an electrical field and stores electrical energy in the form of charge.

Apart from the high temperature range, the UFW1A333MRD offers numerous other features crucial for durability and reliability. It is designed with a rapid thermal deformation that helps it to reach the working temperature faster and prevents overload during startup. It has a high ripple current capability, which allows it to withstand high levels of AC current passing through it, while simultaneously reducing its ESR, leading to higher efficiency and frequency performance. Additionally, the capacitor has a capacitance up to 1000μF, making it suitable for a wide range of applications.

In summary, the UFW1A333MRD is a high-performance capacitor suited for a wide range of applications. Its wide temperature range, high ripple current capability, and high capacitance make it one of the most reliable and durable aluminum electrolytic capacitors available on the market.
