UPJ1HR68MDD

Aluminum electrolytic capacitors are passive electronic components utilized in various applications to store electric energy temporarily. UPJ1HR68MDD is an emblematic aluminum electrolytic capacitor from Nichicon Corporation, a Japanese manufacturer of electronic devices and components. In this article, the application field and working principle of UPJ1HR68MDD will be analyzed in detail.

UPJ1HR68MDD is a radial lead type aluminum electrolytic capacitor featuring an operating temperature range between -40°C to +85°C. This part is also able to solidify itself by forming a layer of insulation during the soldering process. Furthermore, it includes a hermetically sealed, glass-to-metal interface for high voltage, as well as an applied moisture-resistant coating for reverse connection protection. With a Endurance(Time) of 1000 hours at 85°C and a capacitance range between 6.8μF and 68μF, the UPJ1HR68MDD is designed specifically for automotive, telecommunication, health care, and domestic appliances, and frequently used in power supplies, snubber circuits, and signal coupling.

The working principle of the UPJ1HR68MDD can be divided into two parts - electrical and physical:

Electric: The UPJ1HR68MDD comprises two electrically conductive surfaces. When a potential difference is applied, the capacitor separates these surfaces electrically, forming an electric field. This electric field creates a built-in potential difference between the two surfaces, causing electric charges to flow between them. By applying a charge to one surface, an equal and opposite reaction is produced on the other surface. This charge acts like an electric storage device.

Physical: The upj1hr68mdd consists of an aluminum oxide film. This film acts as a dielectric layer, allowing the electric charges to flow between the two surfaces. This oxide layer, measuring only three to five thousandth’s of an inch in thickness, is extremely effective at conducting electricity. The dielectric layer increases the capacity of the capacitor, and prevents it from becoming overloaded.

In summary, the UPJ1HR68MDD aluminum electrolytic capacitor is designed especially for automotive, telecommunication, health care, and domestic appliances, and used in power supplies, snubber circuits, and signal coupling. The UPJ1HR68MDD capacitor accomplishes energy storage by combining electric charge and physical dielectric layers.
