DESCRIPTION
The 2N4338/4339/4340/4341 n-channel JFETs are designed
for sensitive amplifier stages at low- to mid-frequencies. Low
cut-off voltages accommodate low-level power supplies and
low leakage for improved system accuracy.
The TO-206AA (TO-18) package is hermetically sealed and
suitable for military processing (see Military Information). For
similar products in TO-226AA (TO-92) and TO-236 (SOT-23)
packages, see the J/SST201 series data sheet.
