SMD to TO-92 Adapter – QTY 10


A super small SMD to TO-92 adapter – dual sided for JFET or BJT

NEW – Interactive B.O.M Helper

We include a standalone HTML file with each of our boards that helps show you what parts go where (find it in the “Build Docs & Extra Info” Tab)- just extract the zip file to a folder and open the .html file in your internet browser. You can use the table on the left to tick off the parts as you source them / add them to the board – we found its a very handy and a big shout out to Interactive HTML BOM Plugin which is a free plugin on GitHub used to generate these.

So many circuits call for the use of J201/2N5457 JFETS - which are out of production in TO-92 packages and a lot of the examples for sale online are sadly counterfeit. Thankfully there are SMD versions of the transistors which are super cheap and easy to source.  Our board allows you to solder an SMD JFET then use header pins (just bend the pins slightly outwards) or wire to connect to the standard DSG holes on the board.  We've also included a version on the back side for BJT's using CBE as these are moving more to SMD as time goes on.

The examples in the gallery show our board being used with a J201 on our boost pcb. You can see how tiny they are!
