UPJ1V470MED

Aluminum electrolytic capacitors are widely used in many electronic designs, and come in a number of shapes and sizes. One such capacitor is the UPJ1V470MED, a long life, high temperature, surface mount capacitor. The uses of this particular capacitor are varied and its working principle is straightforward.

The uPJ1V470MED is a radial aluminum electrolytic capacitor, having two leads and a solid electrolyte in between. The capacitor consists of two layers of aluminum foil, which are separated by a dielectric separator. The electrolyte is composed of aluminum oxide and is held in place by a polyphenylene oxide (PPO) insulation material. The capacitor is filled with an organic electrolyte, allowing it to be used in high temperature applications.

It is specifically designed for use in automotive, industrial, and consumer electronic products, where electrolytic capacitors are often required. The UPJ1V470MED can be used to filter and stabilize both AC and DC voltages, and is commonly used in power supplies, audio systems and other electronic applications. In addition, because of its low leakage current and extended temperature range, it is suitable for high frequency applications, such as mobile phones and smart cards.

The UPJ1V470MED is also a high temperature capacitor, capable of handling temperatures up to 125°C. This is especially beneficial for applications where temperature fluctuations are frequent, as it allows the capacitor to continue functioning even at extreme temperatures. The device also boasts a long expected life of more than 2000 hours and a very low ESR of 0.14 ohm.

The working principle of the UPJ1V470MED is based on the capacitive properties of an electrolytic capacitor. The two aluminum foils of the device were joined in series and separated by a thin dielectric separator, usually made of paper, plastic or rubber. The capacitor is filled with an electrolytic liquid, which forms a conductive path between the two electrodes. When a voltage is applied to the capacitor, charges accumulate on the aluminium foils, creating an electrical field with opposite polarity charges on each foil. This sets up an electric field between the two foils, allowing the capacitor to store a charge.

The UPJ1V470MED is an excellent choice for many applications, due to its extended temperature range and long expected lifetime. Its low ESR and low leakage current make it ideal for high frequency and other electronic applications. The device is highly reliable and easy to use, making it an ideal choice for a wide array of applications.
