Tiny inductors have best current rating for their size

Just 2 mm high and 4 mm square, the XFL4020 inductors offer a new level of efficiency and current handling. They're made from a special material that provides magnetic shielding and soft saturation characteristics. The XFL4020 has been chosen by Texas Instruments for use with their tiny new TPS63020 4A converter.

Miniature flyback / stepup transformers
are ideal for energy harvesting applications

These 3.5 mm high LPR6235 transformers are perfect for ultralow voltage step-up converters used for energy harvesting, like the LTC3108 from Linear Technology. They're highly efficient, with a coupling coefficient >0.95. Ratios from 1:20 to 1:100 are available.

Which of our RF chip inductors has the highest Q?
This new web tool tells you instantly!

Enter your inductance and operating frequency and in less than 2 seconds you'll see a list of parts with the highest Q factors. Check off the ones you're interested in and you'll get graphs comparing their Q, L, Z and ESR side-by-side.

Trying to compare the performance curves of several RF inductors? This tool makes it easy!

Now you can plot the Q, L, Z and ESR of up to 4 inductors side by side on the same graphs. No more flipping from datasheet to datasheet. Plug in your operating frequency and compare specifications at that precise point. A Coilcraft exclusive!  

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 1000'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.
