Aluminum Electrolytic Capacitors: URZ1A221MDD Application Field and Working Principle

Aluminum electrolytic capacitors (AECs) are electronic components that feature a low profile and relatively long service life. They are commonly used in wide variety of consumer and commercial devices, including audio equipment, medical equipment, and consumer electronics. In this article, we will discuss the application field and working principle of the URZ1A221MDD, a common type of AEC.

Application Field

The URZ1A221MDD is a radial leaded, axial-leaded, aluminum electrolytic capacitor. It is designed for general purpose use and has a fairly low profile, making it suitable for limited-space applications. This type of capacitor is typically used in audio equipment, computers, lighting equipment, and any other applications that require a low-profile, reliable capacitor.

Technical Specifications

The URZ1A221MDD is a 220uf, 63V capacitor. Its rated operation temperature range is from -55°C to 105°C, and it has a maximum ripple current of 50mA. It also has a lower ESR than comparable AECs, making it an ideal choice for applications where low-noise operation is required. The capacitor also features a radial lead diameter of 8mm and a length of 5mm, making it suitable for compact applications.

Working Principle

The URZ1A221MDD utilizes an aluminum electrolytic design in which an electrolyte is sandwiched between two aluminum electrodes. When a voltage is applied across the capacitor, the electrolyte and aluminum electrodes form a conductive path. This allows current to flow from one electrode to the other, creating a stored charge and a dielectric effect. This dielectric effect is what gives aluminum electrolytic capacitors their high capacitance. The URZ1A221MDD also features a Long Life Design that prolongs the capacitor’s life and reduces the risk of failure due to corrosion, fatigue or other factors. This is accomplished through a combination of design and construction techniques, including the use of material modifiers and a special electrolyte formula.

Conclusion

The URZ1A221MDD is a highly reliable aluminum electrolytic capacitor that is roughly one tenth the size of electrolytic capacitors of the same capacitance. Its low-profile design makes it ideal for applications where space is limited, and its Long Life Design ensures a long service life. The URZ1A221MDD is a reliable and cost-effective capacitor for a variety of applications.
