LSK 489 Ultra Low Noise-Capacitance JFET
The LSK489 is high-performance monolithic dual N-Channel JFET that provides excellent low-noise performance in a design that has very low input capacitance (Ciss). The part is used in many ultra-high- end applications.
This capsule (TO-71) also makes it possible for DIY use.
Ultra Low Noise: en = 1.8nV/√Hz
Low Input Capacitance: Ciss = 4pF
RoHS Compliant: Yes
