RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Würth WE-CAIR P/N 74491 SMD Air Coil Inductor Designer Kit for Sale

"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 send you an online-payable invoice. Please send me an e-mail with your shipping information and I can get you a total price. Package size is 3"x9"x13", weight is 3-4 pounds.

Wurth Electronics Midcom, if you are not familiar with the company, is part of the Germany-based Würth Elektronik Group. Combined, they produce thousands of circuit board-based system components for power distribution, display and control panels, electronic controls. Power magnetics, EMC components, common mode chokes, capacitors, transformers, RF inductors, high current PCB terminals, printed circuits boards, terminal blocks, automotive magnetic components, connectors, electronic displays, LEDs, control units, and keypads are among the offerings. Surface mount and through-hole packages are available. There used to be a notice on the webpage offering FREE samples of catalog items on request, but it's not there anymore. Maybe they still will if you ask nicely ;-)

If you are a circuit designer, you might benefit from one of their Design Kits. There are at least 100 really nice Design Kits available with various types of inductors (air, ferrite core, ceramic, SMD, through-hole, etc.), power line chokes, LAN interface transformers, EMI suppression ferrites, a huge variety of shielded and unshielded connectors, ESD suppressors, varistors, fuse holders, DC connectors (think wall wart interface), SEPIC converter, and beryllium EMI finger type contacts. The web page descriptions all say "free refills" for the kits - what a deal, eh?
