Aluminum electrolytic capacitors are components that store electricity used mainly in electronic products for power supply and signal coupling. UPW0J821MPD1TA belongs to aluminum electrolytic capacitor, and this article is to introduce its application field and working principle.

All aluminum electrolytic capacitors use aluminum foil with an oxidized film on the surface as one electrode and an electrolyte as the other electrode. A separator is sandwiched between them. When a direct current is applied, the electric charge will be induced and stored in the dielectric layer formed due to oxide film on the surface of aluminum foil. UPW0J821MPD1TA is a small aluminum electrolytic capacitor with a capacity of 0.047uF (47nF). Its insulation resistance is 20MΩ and its voltage range is up to 10V.

UPW0J821MPD1TA’s application field is wide, such as preventing excessive power supply current affecting the power supply, filtering power supply, filtering out noise interference in the signal, compensating signal transmission line and oscillating circuit. Moreover, it is suitable for general-purpose circuit in the frequency range of 10kHz to 10MHz and also for special-purpose circuit up to 100MHz. It is widely used in computers, computer peripherals, TVs, household appliances, etc.

UPW0J821MPD1TA is suitable to be used in the circuits of DC blocking, AC coupling, coupled filter, bypass filter. In DC blocking, the capacitor blocks DC, allowing only AC to pass through the circuit, so that the signal can not enter the following circuit. In AC coupling, also known as DC isolation, the capacitor keeps the DC component of the signal away from the following circuit and only the AC component flows through.

For coupled filter, which uses different frequencies in the signal, the capacitor can select the desired signal to be sent to the next circuit, while the unwanted frequencies are filtered out. In bypass filter, the capacitor can bypass the power supply interference and low frequency noise, protecting the circuit from damage. In addition, the capacitor can also be used in signal delay, signal timing and regeneration circuits.

UPW0J821MPD1TA has consistent and reliable electrical properties due to the evenly dispersed oxide film, making it exceptionally resistant to heat, humidity and other environmental conditions. This capacitor also has a long service life that range from 3,000 hours to 10,000 hours.

In conclusion, UPW0J821MPD1TA belongs to aluminum electrolytic capacitor, and it can be used in various electronic products for signal coupling, signal filtering, and power supply. Thanks to its consistent and reliable electrical properties and long service life, it is suitable for various applications in a wide range of frequencies.
