Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various electronics and electrical equipment, providing more stable performance due to their high capacitance per unit volume. Within this class of capacitors, the SLP391M250E3P3 model is an electromechanical capacitor that specializes in ripple current applications. This article provides an overview of the SLP391M250E3P3’s applications fields and working principle.

Applications

The SLP391M250E3P3 model is an aluminum electrolytic capacitor that targets applications requiring high ripple current and/or high capacitance. The capacitor series is well-suited for storage/back-up and short-term/power quality applications requiring electrical energy storage, such as household appliances, audio equipment, UPS systems, and DC/DC converters. The capacitors are also suitable for use in high-end switching power supplies, as well as other products with high-density and low-profile designs.

Features and Specifications

The SLP391M250E3P3 series has the following features and specifications:

• Rated capacitance up to 1000uf;
• Operating temperature range from -25°C to +105°C;
• Voltage range 25VDC - 100VDC;
• Leakage current (I_L) of 0.2 uA max;
• Premium electrolyte used for improved high temperature operating life;
• High ripple current rating of 2A;
• Resin sealed to protect against leakage; and
• Tinned leads on the capacitor casing for easy soldering.

Working Principle

SLP391M250E3P3 aluminum electrolytic capacitors function similarly to other types of electrolytic capacitors. The SLP391M250E3P3 contains two conductive surfaces separated by an electrolytic material (electrolyte). One surface (the anode) is made of aluminum with an oxide layer that acts as the dielectric. This oxide layer is the key to its extremely high capacitance.

When electrical energy is applied, the oxide film is reduced, freeing up electrons that form a conductive layer. This conductive layer is known as “electrolyte,” and it is the actual capacitance of the capacitor. The capacitance of the SLP391M250E3P3 is extremely high (up to 1000uf, compared to just a few uF for most electrolytic capacitors) due to its use of a special electrolyte.

When the electrical current passes through the capacitor, it creates an electrostatic field that produces an “electric field” between the anode and the cathode. This electric field opposes the current, causing it to be reduced. This is known as the “capacitance” of the capacitor, and it allows it to store and release electrical energy.

Conclusion

The SLP391M250E3P3 is an excellent choice for applications requiring a high capacitance and/or a high ripple current. It features a high capacitance (up to 1000uf), a high ripple current rating (2A max), and a wide operating temperature range from -25°C to +105°C. Its electrolyte also provides excellent performance in high temperature environments, making it ideal for use in a variety of products.
