Additional Details

Given its 'Hard To Find' categorization, obtaining the exact datasheet for the 2SC2347 may prove challenging. When considering replacements, focus on transistors with similar low noise figures and high transition frequencies to maintain optimal performance in the target application. Check the pinout carefully to ensure correct installation. Appropriate biasing is crucial to achieving the desired low-noise characteristics.

While finding the original Toshiba datasheet is recommended for precise specifications, thoroughly compare substitute transistor parameters against available data to guarantee compatibility and avoid circuit damage. Consider consulting application notes for similar RF transistors to optimize circuit design and performance.
