"Why be Würth-less when you don't have to be?" (I coined that slogan for them).
The "SMD Air Coil Inductor Design Kit" by Wurth Elektronik (P/N
74491) contains a wide variety of surface mount, wire-wound, air core inductors
for use while prototyping circuits.
Digi-Key sells this exact kit for $143.85, and usually they have the best prices
anywhere. All the inductors that came with it are present and have never been used
or even removed from their packaging. Note: This kit is a coupe years old, so reference
the chart in the box top regarding what parts are included.
You can be the proud owner of this kit for only $65 + shipping. I can have PayPal
