Matched JFETs

Idss Choices One of the most common questions is what Idss sub-group to choose.  All JFETs are grade B/BL (6-12mA).  You can select from an Idss sub-range. If you are building any of the First Watt products, Nelson has provided a summary.  Learn more about how to choose the right Idss for your project.  Project use reference Below is a list of JFETs required for some of the most common projects. P Channel Quad: AlephJ, BA1 Gain Stage, ACP+ N Channel Quad: Mezmerize  NP Quad: F4 F5 F5T V1/2/3 F6 BA3 Gain Stage   F5T V3 Balanced (Qty 2) Notes All matches are guaranteed within ±0.2mA. Test conditions are 10V @ 22'C. For more information visit the JFET matching information page. Manufacturer specifications: LSK170 | LSJ74 | 2SK170 | 2SJ74 Any letters or numbers printed on Linear Systems JFETs are batch identification and do not reference the grade / Idss range. You must test the JFET to determine the Idss / grade. Quantity Limits N Quads: Limit of 8 units per customer per m
