Aluminum Electrolytic Capacitors

DCM302U075BC2B is a type of aluminum electrolytic capacitor manufactured by BQC Electronics. Aluminum electrolytic capacitors are commonly used in power systems, especially in UPS systems. Such capacitors are \'polarized\' capacitor units consisting of aluminum or tantalum anodes, separators, and cathodes, which are dipped into (or sprayed on) a petroleum-based or solid electrolyte containing mainly aqueous-based ions.

Application field

DCM302U075BC2B is a high-performance aluminum electrolytic capacitor with a wide operating temperature range of -40°C to +105°C. This type of capacitor is ideal for the execution of general power line smoothing, circuit decoupling, and delay timing applications. Some typical applications include solid-state switching power supplies, voltage regulator, and signal processing applications.

Working Principle

Aluminum Electrolytic Capacitors such as the DCM302U075BC2B work by allowing charge to pass through the capacitor when the terminal voltage is applied across it. The charge carriers are positively charged aluminum ions, which are attracted to the negatively charged electrode. This creates an accumulation of positive charges on the surface of the aluminum electrode. The opposite process occurs on the other side. The separation of charges creates a capacitive effect, or a change in capacitance. Different types of electrolytes alter the capacitive effect.

The capacitance of the DCM302U075BC2B capacitor is dependent on a number of factors, including the thickness of the dielectric, the distance between the two electrodes, and the strength of the electric field. These capacitors are rated for up to 2.0kV and 7500uF with a temperature coefficient of +297ppm/°C and an endurance rating of 3000hours. This makes them ideal for applications that require long-term reliability and durability.

The DCM302U075BC2B is capable of withstanding a wide range of temperatures and still maintain its performance and durability, making it a great choice for applications where extremely high temperatures may be encountered. Thanks to its robust construction, it can handle impact, vibration, and temperature shock without affecting the capacitor\'s performance.
