Aluminum - Polymer Capacitors

Aluminum - Polymer Capacitors, or ALCAPs, are some of the newest types of capacitor technology available. Made up of two materials and using a laminated dielectric system with metal electrodes, these capacitors are used for many different applications.

The 476ALG050MFBJ capacitor is a well-known part of the ALCAP family. This specific model is a 476mlg rated capacitor, meaning it can operate with a voltage of up to 750 volts AC. Additionally, the working temperature range is -40 to +105°C, making it suitable in a wide range of environment conditions. With a small package size (11.3 x 9.3 x 0.7mm) and low ESR (Equivalent Series Resistance), this ALCAP is an ideal choice for situations where board space is limited.

In terms of its application field and working principle, the 476ALG050MFBJ is suitable for a variety of applications. It’s an excellent choice for high power devices, including power supplies and motor drives. Thanks to its high rated current rating, it’s also a great fit for high current circuits, or for applications where high noise suppression is required. Its ability to withstand large voltage pulses is also beneficial for robust motor control applications.

The primary purpose of an aluminum - polymer capacitor is to store energy in the form of an electrical charge. The principle behind this is quite simple - unlike electrolytic capacitors which use a chemical reaction to create a charge, an ALCAP uses a sandwich-like structure composed of two alternating layers of metal and polymer films. Each layer of the sandwich is called an “electrode” and when a voltage is applied to the two electrodes, the two films polarize in opposite directions – the positive charge is stored in the polymer film and the negative charge is stored in the metal film.

The charge stored in the capacitor can then be used for a wide variety of purposes. Depending on the application, the capacitance of the capacitor can determine the amount of charge stored and how quickly it can be discharged. The ALCAP also has a very low equivalent series resistance (ESR). This means that the device can discharge faster than other types of capacitors, thus permitting higher current output and improved noise suppression.

For its many advantageous features, the 476ALG050MFBJ is a top choice for many modern applications. It’s small size, extended temperature range, and excellent ESR characteristics make it a reliable choice for applications where board space is limited and high performance capacitors are desired. With its impressive safety ratings and ability to withstand high AC voltages and temperature ranges, this ALCAP will continue to be a favored choice for many applications.
