UPM0J272MHD1TO Capacitors

Aluminum electrolytic capacitors, also known as \'electrolytic capacitors\', are a special type of capacitor that combines two dissimilar materials, one of which acts as an electrolyte and the other as a dielectric, in order to provide an electric field in which the electrostatic energy is stored. These capacitors are used in a variety of applications, like in power supplies for electronic circuitries, as dampening devices in AC motor speed control systems, for bypassing and filtering of AC and DC voltages, in motor start circuits and for dynamic braking of electrical motors.

The UPM0J272MHD1TO is an aluminum electrolytic capacitor from the UltraLife series of Panasonic. This device has a very high capacitance of 270µF and a maximum working voltage of 50V. It has very low leakage current ratings and can withstand up to ±20% in capacitance tolerance. The device also has long life span of 7000 hours and is extremely small in size with diameter of 10.2mm and length of 20mm.

This specific type of capacitor is mainly used in power applications since it is able to handle large capacitance and high voltage requirements. The UPM0J272MHD1TO can also be used in medical equipment, automobiles and small appliances. It is also suitable for power-on reset circuits and for timing and low level noise suppression applications.

The working principle of an electrolytic capacitor is similar to that of a non-electrolytic capacitor, with two plates being placed close together, but the electrochemical reaction between the dielectric and the electrolyte are what gives the electrolytic capacitor its unique properties. An electric current is sent through the electrolyte, creating an electric potential difference between the two plates of the capacitor. This in turn creates a static electric field within the dielectric, effectively storing an electric charge within the capacitor.

It is important to note that unlike regular non-electrolytic capacitors, the UPM0J272MHD1TO has a polarity and does not have an infinite lifespan. The cathode of the device must always be connected to the higher then the anode voltage in order to ensure the device works properly. If the voltage polarity is wrong or the device is over-voltaged, the electrolyte will break down and cause a significant reduction in the capacitance of the device. This is why it is important to properly determine the correct orientation of the polarity of the device before use.

In summary, the UPM0J272MHD1TO is an aluminum electrolytic capacitor from the Panasonic UltraLife series designed to provide high capacitance and suitable for power applications across a wide range of voltages. It has a long life span and can withstand up to ±20% in capacitance tolerance. It is also suitable for various power-on reset circuits and its polarity must be respected in order to ensure its proper functioning.
