ULD2A4R7MDD

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used types of capacitors in electronics and electric applications because they offer the highest capacitance value per unit volume compared to any other type of capacitor. An aluminum electrolytic capacitor, also known as an electrolytic capacitor or a wet capacitor, is a type of capacitor that uses aluminum foil as its electrodes and uses an electrolyte (an ionic compound) as its dielectric. This type of capacitor is also referred to as a polarized or nonpolarized capacitor, depending on the construction of the anode and cathode; nonpolarized capacitors are mainly used in general electronic applications while polarized ones are most commonly used in power circuit applications.

ULD2A4R7MDD is an aluminum electrolytic capacitor with a capacitance value of 2,000 uF (microfarads). This value is quite low, but the capacitanc is still well suited for many applications. The ULD2A4R7MDD has a maximum operating temperature of 105 degrees Celsius (°C) and voltage limit of 250 volts (V). With dimensions of 25.3 mm diameter x 9.5 mm length, the ULD2A4R7MDD is a relatively large capacitor when compared to other electrolytic capacitors of similar size. It is also typically more expensive than most other types of capacitors.

The ULD2A4R7MDD is typically used in power supply circuits and voltage regulation circuits. It acts as a filter for AC (alternating current) and DC (direct current) power supplies, helping smooth out low voltage fluctuations. It can also be used in battery back-up circuits, where it stores energy and discharges it when the main power source fails. Since electrolytic capacitors are polarized, the negative lead marked in specific ways must be connected to the cathode in order for them to work properly.

The dielectric of an electrolytic capacitor is an electrolyte, which is a mixture of liquid and electrolyte charges. It is this dielectric that gives the capacitor its high capacitance value. When a voltage is applied to the capacitor, the electrolyte charges are drawn to the aluminum electrodes in the anode and cathode, which results in the creation of an electrical field. This field stores the charge, which increases the capacitance of the capacitor. The capacitance of an electrolytic capacitor can be considered as its “capacity”; it indicates how much charge can be stored within the device before it starts to slow down and eventually fail.

In summary, the ULD2A4R7MDD is a large and expensive aluminum electrolytic capacitor that is mainly used in power supply and voltage regulation circuits. It has a capacitance value of 2,000 uF and maximum operating temperature of 105°C. It is typically used in battery back-up circuits and AC and DC power supplies, where it smooths out low voltage fluctuations. It is also a polarized capacitor, so the negative lead must be connected to the cathode for it to work properly. The dielectric of the ULD2A4R7MDD is an electrolyte, which is a mixture of liquid and electrolyte charges. This dielectric store the charge, which increases the capacitance of the capacitor.
