The ERM1KM330F12OT with Aluminum Electrolytic Capacitors - Leaded 33uF ±20% 100V Radial,8x12mm RoHS manufactured by Aishi is an electronic part designed to help control and regulate power in electronic circuits. It is a radial-type capacitor, which means it is cylindrically shaped and has two leads extending from each end that allow it to be mounted upon a printed circuit board. This component has a rated capacitance of 33µF (microfarads), which is a measurement of its ability to store charge. It also has a rated voltage of 100V, which is the maximum amount of voltage it is able to withstand before breaking down. Additionally, it has a tolerance of ±20%, meaning the actual value of the capacitance can range from 26.4 µF to 39.6 µF. Lastly, it is RoHS Compliant, meaning that it meets the European Union's requirements for hazardous materials, which helps prevent environmental damage.
