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.
