2SJ74 + 2SJ74 + 2SJ74 + 2SJ74 (BL)
Toshiba Super Matched Quad (4 ea)
J-FET Audio Transistors
..........
These JFETs were matched at a constant 72 degrees using a meticulous lab process.
JFETs are inserted into a custom 90-socket gold-pin ZIF test jig (30 devices per test).
A well-regulated and carefully monitored DC supply voltage of 9.00V (not 9.01V) is
applied while FETs are allowed to stabilize for at least 5 minutes before testing.
Current (Idss) and voltage (Vgs) are then measured quickly on a calibrated
Agilent 34401 6-1/2 digit meter. FETs are matched in pairs to within 0.03mA Idss
AND 4mV Vgs.In many cases, the matching is within 0.01mA and 1mV.
We have bags of matchedP-ch pairs (7.0 to 9.9 mA range). Buyers will receive
the tightest matching available,prioritized by Idss. Single shipments over $200 get
a 5% discount (remind me).
