BF1212R Overview
Enhancement type N-channel field-effect transistor with source and substrate interconnected. Integrated diodes between gates and source protect against excessive input voltage surges. The BF1212, BF1212R and BF1212WR are encapsulated in the SOT143B, SOT143R and SOT343R plastic packages respectively.
BF1212R Key Features
- Short channel transistor with high forward transfer admittance to input capacitance ratio
- Low noise gain controlled amplifier
- Excellent low frequency noise performance
- Partly internal self-biasing circuit to ensure good cross-modulation performance during AGC and good DC stabilization
BF1212R Applications
- Gain controlled low noise VHF and UHF amplifiers for 5 V digital and analog television tuner applications. DESCRIPTION Enhancement type N-channel field-effect t
