Achieve new performance benchmarks with Fairchild Semiconductor's MMBF4119 JFET transistors, specifically engineered for phase-sensitive detection circuits. The unique triple-diffused structure minimizes 1/f noise while delivering 0.1dB gain flatness across bandwidths to 100MHz. Medical imaging systems and lock-in amplifiers benefit from these precision characteristics. Check stock availability through our real-time inventory system or ask about custom testing protocols for mission-critical deployments.
