SyQwest
For over 20 years Interfet has supplied our company with JFET's. To date we have purchased almost 3 million components. The team over at Interfet has always gone above and beyond to accommodate our needs. I try my best to give a schedule that includes their stated lead time and to not change it once in place. But on the rare occasion that I need parts quicker or need to adjust the schedule the team is always more that willing to work with me. They also try to anticipate my future needs and bring it to my attention when my Po's are getting near the end so that I do not run short on inventory.
