PRODUCT OVERVIEW
The 2900 series is a range of bobbin-wound,
shielded inductors. They are suitable for power-
line filtering found in consumer electronics such
as desktop computers, handheld devices 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.
For lower current ratings see also our lower
profile 2900L series.
