36DX191F450AB2B

Aluminum Electrolytic Capacitors

36DX191F450AB2B is an aluminum electrolytic capacitor, which means it is constructed with aluminum foil, and is primarily composed of a rolled-anode, separator, and electrolyte. Fundamentally they work as a standard capacitor and store energy through electrostatic action. The energy is stored in the capacitor by transferring electrons from the anode material through an ion exchange in the electrolyte. It is discharged when the electrons are allowed to return to their origin.

Application Field

Aluminum electrolytic capacitors, such as 36DX191F450AB2B, are used in a variety of applications depending on their voltage rating, capacitance, and ESR (equivalent series resistance) ratings. Some common fields of use are in power supplies, audio crossover networks, filters, electronic timers, and pulse generators to name a few. These capacitors are also widely used in solid-state rectifiers to assist in smoothing out the AC mains ripple.

Working Principle

The 36DX191F450AB2B capacitor is constructed with an oxidized aluminum anode foil which is etched with microscopic pores. The anode is then rolled up with separator material which is soaked in electrolyte. The vacuum seals the capacitor against any air getting in and corroding the electrolyte. This sealed capacitor is then encased in special epoxy resin and then attached to two lead wires which take the form of pins and later on enclosed in a case. When the capacitor is charged, electrons are transferred from the aluminum anode through the ion-exchange in the electrolyte and onto the cathode. When the capacitor is discharged, electrons are allowed to flow back onto the anode which completes the capacitor’s cycle.

Conclusion

The 36DX191F450AB2B capacitor is an aluminum electrolytic capacitor, specifically designed for a wide variety of applications. Its working principle is based on the ion-exchange of electrons between the anode and the electrolyte, and it is able to store energy by doing so. This type of capacitor has excellent performance and reliability characteristics over other types of capacitors and is suitable for applications like providing power to electronic equipment, smoothing a DC output, or filtering a DC signal.
