ElectronicsThe ERR1HM220D11OT Aluminum Electrolytic Capacitor - Leaded 22uF ±20% 50V Radial,5x11mm RoHS manufactured by Aishi Electronics is an electronic component used in electrical circuits. It is an electrolytic capacitor constructed from two aluminum plates and a separator soaked in a dielectric liquid. The leads of the capacitor are connected to the two aluminum plates while the separator provides dielectric insulation between them. The capacitor works by storing electrical charge and supplying current to improve circuit performance. It is typically used in power supplies, filter circuits, motor drives, and audio applications. This particular capacitor is rated at 22uF, ±20% tolerance, and has a voltage rating of 50V. It also has a 5x11mm RoHS form factor, meaning that it sits flat and has five terminal pins, with an 11mm diameter.
