Aluminum electrolytic capacitors (AECs) are widely used in various electrical and electronic circuits. They have many advantages in comparison with other types of capacitors due to their relatively low cost, large capacitance values and low equivalent series resistance (ESR). The 226SML6R3M is an AEC with a very small footprint. It has a rated capacitance of 6.3 uF, rated voltage of 25 V and rated temperature range of -55 °C to +105 °C.

The 226SML6R3M AEC is suitable for use in a wide range of applications, including power supplies, motor drives and converters, automotive electronics, and industrial electronics. It is also well-suited for various energy storage applications such as for powering electronic devices when the mains AC power is not active. This capacitor is widely available in various sizes and shapes, including Radial, SMD and Snap-in models.

The basic working principle of AECs is simple. When DC current and voltage is applied across the two terminals of the capacitor, an electric field builds up inside the liquid electrolyte present in the capacitor. This electric field causes ions to move through the liquid electrolyte and to accumulate on the aluminum oxide dielectric, creating a positive charge on one side of the capacitor and a negative charge on the other side. This charge imbalance across the capacitor results in the build-up of the electric field which gives the capacitor its capacitance value.

In a 226SML6R3M AEC, the electrolyte is typically a mixture of sodium hydroxide and ethylene glycol, which ensures that the ions can move freely in the electrolyte. The dielectric layer is comprised of a very thin layer of aluminum oxide, which acts as an insulator and is responsible for maintaining the charge balance across the capacitor. The aluminum foil is sandwiched between two electrodes, which provide the terminals for the capacitor.

The 226SML6R3M AEC is highly reliable and compact. It has a long useful lifespan, even when exposed to extreme temperatures, humidity, and vibration. Its small size makes it ideal for use in applications where space is limited. It also provides excellent electrical characteristics, such as low ESR and high ripple current capability, allowing the capacitor to work efficiently in most applications.
