The R463I347050M1K with Safety Capacitors is a .47uF, 310VAC 10% X2 Rad capacitor manufactured by the company Kemet. It is a safety capacitor, meaning that the casing is designed to contain any arcing, fire, and other hazardous events caused by a short circuit or over-voltage situation. The safety capacitor also helps to protect against electromagnetic interference (EMI). The X2 Rad specification indicates that the capacitor is designed to be used in applications where the AC voltage is less than 275Vrms. Additionally, the 10% tolerance indicates that the capacitance of these capacitors may vary by up to ±10%. This component is perfect for use in a range of applications like DC-DC converters, SMPS, PWM controllers, EMI filtering, and many more.
