8 Super-Matched 2SJ74 (GR) ("A")

Toshiba Super-Matched Octet

Total 8 pcs Ultra-Low-Noise

J-FET P-Channel Audio Transistors

..........

These JFETs were matched at a constant 72F 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 some cases, the matching is within 0.01mA and 1mV. The

actual measured Idss and Vgs is noted on each packing bag. 

ALL 8 FETs will be prioritized Idss-matched to within 0.03mA. 

Only a handful of octal-match sets can be achieved in a production matching run. 
Currently have 2SJ74GR in the 4-5mA range. Perfect for ultra-low-noise front-ends.
When they're gone, they're gone.  Orders over $200 get 5% discount.
