Additional Details

The 2SC1166Y is typically packaged in a small signal transistor package, such as a TO-92 or SOT-23. The 'Y' suffix often indicates a specific gain grouping or characteristic. The transition frequency (fT) is a key parameter for high-frequency transistors, indicating the frequency at which the current gain drops to unity. The low collector-base capacitance helps to minimize feedback and maintain stability in high-frequency circuits.
