ELZA250ELL152MK25S

Aluminum-Electrolytic Capacitors are widely used in various applications, from power supplies to precision timing devices. In this article, the ELZA250ELL152MK25S model of aluminum electrolytic capacitor, will be highlighted and characteristics and application areas discussed.

Construction and Working Principle

A typical aluminum electrolytic capacitor consists of two aluminum foils separated by a film of paper soaked with a solution of electrolytic material, usually a mixture of boric acid, glycerin or silicone fluid. The two aluminum foils are wound together to form the capacitor, and can have different diameters. One aluminum foil serves as the dielectric, and the other is the conducting electrode. This design gives the capacitor the ability to store more charge than any other capacitors. This is because the larger the diameter of the conductive electrode, the greater the amount of charge that can be stored in the dielectric.

When current is applied to the capacitor, the electrons from the negative foil move to the positive foil, which increases the capacitance of the capacitor and is how the capacitor stores energy. At the same time, a reverse current will be created in the reverse direction, which helps to maintain the capacitance. This energy storing capability gives the aluminum electrolytic capacitor an advantage over other capacitors, such as ceramic and film capacitors.

Characteristics of the ELZA250ELL152MK25S

The ELZA250ELL152MK25S is an aluminum electrolytic capacitor that is used in a wide range of applications. It is a radial-leaded device that has two lead-out wires at 90-degree angles. It is generally constructed from aluminum and offers a capacitance value of 250μF. The rated voltage of the capacitor is 50V and it has a capacitance tolerance of ±20%.

The ELZA250ELL152MK25S is large in size and as a result, it is able to store large amounts of energy. The capacitor is rated for temperatures ranging from -40°C to +85°C and can operate at temperatures up to +105°C for short periods of time. The capacitance of the ELZA250ELL152MK25S decreases at temperatures below 0°C, so it is important to take this into consideration when using the capacitor in low-temperature applications.

The ELZA250ELL152MK25S has an impressive ripple current load rating of 625mArms and a 50,000 h life expectancy. It also has excellent dispersion of noise characteristics due to its large diameter. In addition, its ability to store large amounts of charge gives it an advantage over traditional capacitors.

Applications of the ELZA250ELL152MK25S

The ELZA250ELL152MK25S is used in various applications requiring high capacitance and power. These include power supplies, noise filters, timing devices, start-stop systems and switching applications. It is also widely used in consumer electronics such as audio equipment, automotive electronics, LED lighting and home appliances. The capacitor is also used in medical and safety-critical applications due to its large capacitance and excellent electrical characteristics.

Due to its large capacitance and ability to store high amounts of energy, the ELZA250ELL152MK25S is also used in many power supply and voltage regulation applications such as line filtering, pulse/charge/discharge timing, rectifier bridges, motor speed control and DC/DC converters. The high temperature rating of the capacitor also makes it suitable for applications requiring a high temperature rating, such as automotive electronics. Lastly, its excellent noise dispersion characteristics and long life expectancy make it well-suited for applications requiring reliability.

Conclusion

The ELZA250ELL152MK25S aluminum electrolytic capacitor is a large, radial-leaded device that can store a large amount of energy due to its large width. It is suitable for a wide range of applications, from power supplies to precision timing devices, due to its large capacitance and impressive ripple current rating. It is also rated for temperatures ranging from -40°C to +85°C and has a long life expectancy. Keep in mind that the capacitance of the ELZA250ELL152MK25S decreases at temperatures below 0°C so it should not be used in these applications.
