You can't get higher Q in a smaller footprint!
Introducing our new SQ air core inductors.

These are the perfect coils for LC filter and RF impedance matching applications. Most have Q factors above 200 in the 1-2 GHz range. And they're rated to handle up to 4.4 Amps. Get all the details and order free samples here.

You've picked your IC.
Now which Coilcraft inductor should you use?

Use this handy new tool to find Coilcraft products suitable for use with 100's of IC reference designs. Get a sortable list including our newest products that perform better and cost less than those on the application note.

Tiny power inductors offer the highest efficiency
and Isat ratings in a 2 x 2 mm footprint

The EPL2010 and EPL2014 are perfect for EL and other handheld applications. Roughly half the DCR and twice the current handling of competitive parts in a rugged, monolithic, shielded design.

High performance chip inductors have
best Q, DCR & current handling

Our new 0402HP and 0603HP families surpass our existing SM RF inductors in almost every area, without any increase in price! Ask for free evaluation samples.
