DESCRIPTION

The 4600 series is a range of bobbin-wound,

shielded inductors suitable for power-line ﬁltering

found in consumer electronics such as desktop

computers, LED applications and GPS systems,

as well as in a vast range of industrial and

telecom applications including network hubs,

bridges & routers, and high frequency wireless

communication devices.

These surface mount inductors are extremely

compact and have an integral shield, making them

useful in EMI sensitive applications.
