UHE0J331MED

Aluminum electrolytic capacitors are a type of capacitor that uses an aluminum oxide barrier to store a charge. The oxide layer acts as an electrical insulator, keeping the two electrodes within the capacitor from touching each other. The oxide layer also helps separate the aluminum electrodes during polarity reversal, preventing bitth and short circuits. Aluminum electrolytic capacitors are available in both polarized and non-polarized versions, and come in a variety of package styles.

The UHE0J331MED is an Axial Lead Surface Mount Aluminum Electrolytic Capacitor. It is ideal for automotive, industrial, and consumer applications, and is RoHS compliant. It has an operating temperature range of -55°C to 105°C, and is rated for a voltage of 35V. It also features a capacitor tolerance of ±20%, and has a shelf life of 1000 hours.

The working principle of an aluminum electrolytic capacitor relies on the electrical double layer (EDL) phenomenon that occurs when a voltmeter is placed between a conductive electrolyte and a solid dielectric material. EDL results from a negative charge being drawn to the dielectric material, creating an energy barrier between the two materials. This barrier, or capacitance, is a measure of how much charge can be stored in the capacitor.

The EDL phenomenon increases with higher voltage, allowing higher capacitance to be stored in the capacitor. When a voltage is applied to the capacitor, the energy barrier that exists between the two materials begins to creep up. This increases the capacitance of the capacitor, and allows more energy to be stored within it. When the voltage is removed, the capacitance returns to its original level.

The UHE0J331MED has a mounting style of “bottom side”, meaning it can be placed onto a board by soldering the legs from the bottom side of the board. The package comes with a wide variety of caps, including short, free, overvoltage, and PP5 varieties, which makes it suitable for many different applications.

In conclusion, aluminum electrolytic capacitors are widely used in applications ranging from automotive, consumer, and industrial, and are available in both polarized and non-polarized packages. The UHE0J331MED is an Axial Lead Surface Mount Aluminum Electrolytic Capacitor with a wide assortment of caps that make it suitable for a variety of applications. It utilizes the electrical double layer phenomenon to store and release charge, and can withstand temperatures ranging from -55°C to 105°C.
