Sadly, the through-hole J201 is no longer produced, and remaining supplies from ebay/China are so out of spec, they are not usable. SMD is the solution. The SMD (surface-mount device) version of this JFET is still available, and is produced today by leading chip manufacturers with very high tolerances. Great news right? Well, SMD and DIY don't mix well for most (practically all) people.
Check out the size-comparison picture on this page. The SMD package is the black spec to the 2 pieces of instant rice. A regular through-hole JFET is also pictured. Obviously, these things are tiny. While some builders may have "some" smd experience, probably none will match the quality of assembly of these factory-produced prefabricated micro-PCBs with the J201 already soldered into place. Beautiful! The same black-spec-transistor is shown next to the pre-soldered boards.
Sorry, we cannot sell in other increments. This item typically ships via first class mail in a bubble mailer unless purchased at the same time as a kit.
Please verify JFET orientation when you install into your project. We will not be held responsible for damage due to incorrect usage.
