The BFC233860473 is a Safety Capacitor manufactured by Vishay that is 0.047uF (micro Farads) in capacitance, with a tolerance of 20%, and a rated voltage of 300 volts. This capacitor is designed for overvoltage protection in line-connected replacement circuits. It is designed to prevent current rush, AC voltage spikes, and electromagnetic interference from affecting electronic components in a circuit. The Safety Capacitor is covered in a plated disk epoxy resin housing for protection against dirt, moisture, and other contaminates. The BFC233860473 is UL, CE, and VDE approved, and terms EMI/RFI and X2.
