Ferrite Bead

A35 Super Grab Bag.

If you are a builder, here is a deal you can't overlook!  We offer a grab bag with a generous assortment of many of the small parts shown on this page and even items not shown here.  You will get a variety of parts worth up to $50.  The latest batch we made up contains pc boards, crystals, rf coils, powdered iron coil cores, crystal sockets, heatsinks, ferrite beads, led's, rf chokes, 20-turn pots, resistors, ic sockets, toggle switches, sheilds, and more.  Click on thumbnail to enlarge photo.  Note that contents vary depending on what parts we have in excess at any given time, so they will not be exactly as shown in the photo.

Quantities are limited; so hurry to take advantage of this one-time offer.  Those who work in electronics plants often have opportunities to buy left over parts.  Here's your chance to do the same.  Clearance special, only $10 while supply lasts.

A36 Crystal Sockets.

Oops!  We overbought.  Well, we had to because the mfr had a minimum run to stamp these special parts for us.  Our loss, your gain!  These are the sockets we use on pc boards for crystals to plug into.  They can also be used as handy solder terminals to connect wires to pc boards.  They snap in a 0.070 " dia hole and are then soldered to the board. 

So here's the deal.  If you can use some, we're glad to help out.  Retailing for 10 cents each, we can sell them to you for your projects for $5/100, or if you can use a large qty, just $100 for a reel of 18,000 (that's just a little over 1/2 cent each).

A44 Solder-in Feedthrough Capacitor.
