DESCRIPTION
The 4500 series is a lower profile version of our 4600 series range of bobbin-wound, shielded inductors. They are 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. PIN CONNECTIONS (TOP VIEW)
