2SK1842 Datasheet, PDF (1/2 Pages) Panasonic Semiconductor – Silicon N-Channel Junction FET

Silicon Junction FETs (Small Signal)
2SK1842
Silicon N-Channel Junction FET
For impedance conversion in low frequency
For infrared sensor
s Features
q Low gate to source leakage current, I_GSS
q Small capacitance of C_iss, C_oss, C_rss
q Mini-type package, allowing downsizing of the sets and automatic
insertion through the tape/magazine packing.
