DESCRIPTION
The J304/305 n-channel JFETs provide high-performance
amplification, especially at high-frequency. These products
are available in tape and reel for automated assembly (see
Package Information).
For similar products in TO-236 (SOT-23) packages, see the
2N/SST5484 series data sheet, or in TO-206AF (TO-72)
packages, see the 2N/SST4416 series data sheet.
