Part Number: KC472M
Function: Capacitor Ceramic Disk 4700pf, 250V, Spark Killer
Package: Radiral Disk type
This is 4700pf, Capacitor Ceramic. ( MURATA KC472M 0.0047uF CAPACITOR )
A special class of capacitor is used in power-line (mains) filters. Line filtering is a very tough application for a capacitor. Power lines are subject to a variety of disturbances that induce transients and surges. These vary from a few hundred or a few thousand volts (motors and triac controllers) to many thousands of volts (lightning). The filter capacitor has to endure these transients for years without failure, or at worst, failing without exploding, catching fire, or subjecting the user to the risk of shock.
1. Ideal for use as X/Y capacitors for AC line filters and primary-secondary coupling on switching power supplies and AC adapters.
