Electric Double Layer Capacitors (EDLCs) or Supercapacitors are known for their high power density and capabilities to extinguish large amounts of energy in short spans of time. While traditional capacitors store energy statically (dc frequency), EDLCs have the torque and output power in a short-time kinetic process (ac frequency). SCMR22D155MRBB0 is one such capacitor from SCMR series in a radial leaded aluminum polymer construction.

The SCMR22D155MRBB0 capacitor is designed and tested to perform within the specifications of EDLCs supercapacitors. It provides a high frequency operation and offers characteristics of low ESR (Equivalent Series Resistance), high ripple current rating, and low self-discharge rate. It is encapsulated using a flame retardant epoxy resin coating and is highly resistant to organic chemicals and moisture.

The SCMR22D155MRBB0 capacitor is mostly used in applications such as motor control circuits, regenerative braking control circuits, emergency lighting systems, electric car backup systems, 48V power systems, low-voltage power packs, and consumer electronics. It is also used to store energy and serve as a backup power supply in solar and wind power systems.

The working principle of EDLCs is that they store energy in the form of static electricity using positive and negative ions that are enclosed by two thin layers of electrolyte film material between two electrodes. The electric double layers provide very large capacitance ranging from 0.5 to 3000 Farads. During the charging process, the ions in the negative electrode attract electrons from the positive electrode in such a way that the two electrodes become opposite in charges, thus creating a static electric field. During the discharging process, current flows from the positive to the negative electrode, resulting in a static energy transfer.

The SCMR22D155MRBB0 capacitor is highly reliable and robust with respect to temperature and vibration. Its high frequency operation, low ESR, and large capacitance makes it ideal for applications where high efficiency and reliability are required. Its large surface size with extended contact allows for peak current output and long service lifetime.

So, the SCMR22D155MRBB0 capacitor falls under EDLC supercapacitors and is widely used in the above-mentioned applications. It features great capacitance, long lifetime, low ESR, and a very high operating frequency.
