185683K100RHA-F

Film capacitors, also known as film dielectric capacitors, are passive electrical components used in a variety of AC applications. These capacitors are among the most reliable power sources available, and they come in many different forms. The 185683K100RHA-F is a film capacitor from the Vishay Sprague brand.

Components of the 185683K100RHA-F

The 185683K100RHA-F is a metalized polypropylene film capacitor that is part of the Vishay Sprague brand of capacitors. It has an operating temperature range of -55°C to +85°C and a ripple current rating of 4.1ARMS. The 185683K100RHA-F has a rated working voltage of 250VDC and a tolerance of ±3%. The epoxy resin sealed body measures L-23.8 x W-11.3 x H-15.2 mm, and its capacitance value is 100µF.

Application Field and Working Principle

The 185683K100RHA-F is a general-purpose film capacitor that can be used for a variety of applications. These applications include power supplies, switching power supplies, and servo motors. As kinetic capacitance for motor controllers and DC-DC converters, the capacitors provide a stable power supply, fast switching response, low power loss, and good reliability. The metalized polypropylene film insulation of the capacitors gives them reliable performance, low leakage, high insulation resistance, high ripple current, and high capacitance. Moreover, the UL94V-O Epoxy resin sealing increases the insulation reliability to keep the capacitor in full operability even in harsh environments.

In general, film capacitors work by having an electric field between two layers of metalized dielectric material. When a voltage is applied, electric field lines form between the two metalized plates. The amount of charge stored on the two plates is determined by the size of the capacitor and the voltage applied. The dielectric material (in this case, polypropylene) determines the capacitance of the capacitor. As the voltage increases, the dielectric material will begin to break down and the capacitor will eventually fail.
