DESCRIPTION
The 4500 series is a lower profi le version of our
4600 series range of bobbin-wound, shielded
inductors. They are suitable for power-line
fi ltering 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.
