Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, or “electrolytic” capacitors, employ an anode of aluminum, along with etched anode and cathode foils of oxide-coated aluminum, suspended in an electrolyte. Models 53D131G250HJ7 are high value-dissipation aluminum electrolytic capacitors with a radial leaded construction.

Application Field

Many of the benefits derived from the use of aluminum electrolytic capacitors relate to their application field. Commonly seen applications for aluminum electrolytic capacitors include oscillators, filters, regulators, and pulse bifilar circuits due to their ability to handle relatively high ripple current levels. Other applications include motor control, power supplies, and dc-dc converters.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on electrochemical energy conversion. Electrolytic capacitors use an aluminum foil as their anode and surround it with an electrolyte. The electrolyte forms an electrically insulating oxide layer on the anode\'s surface. This layer serves as a dielectric and stores electrical charge.The capacitor polarity is then determined by which electrode is placed closest to the etched portion of the aluminum foil. The positive electrode (also called the plate) is the electrode closest to the etched portion. The negative electrode, or the counter-plate, is the electrode closest to the unetched portion of the aluminum foil.When a voltage is applied to the capacitor, ions of the electrolyte will migrate from the anode to the cathode, forming two capacitive plates, one on each side of the electrolyte. This process creates an electric field between the two plates which stores electrical charge until the capacitor is discharged.

Cutting-Edge Design

53D131G250HJ7 models feature a compact, low temperature-rise design. They are also designed to ensure that their capacitance is held within a very small tolerance (+/-20% ripple current). This makes them extremely reliable for applications that require high capacitance and/or high ripple current.All 53D131G250HJ7 models come standard with an 8mm maximum outer diameter lead, eliminating the need for mechanical modifications. Additionally, they feature a unique screw-clamp one-piece terminal block, giving them the added benefit of superior mechanical stability when compared to other aluminum electrolytic capacitors.

Conclusion

53D131G250HJ7 models of aluminum electrolytic capacitors have a variety of applications, with features that make them suitable for use in oscillators, filters, regulators, and pulse bifilar circuits. They feature a cutting-edge design for consistent capacitance, as well as superior mechanical stability that makes them ideal for use in many applications.
