8541.29.00.75 - With an operating frequency not less than 30 MHz

This HTS category, 8541.29.00.75, specifically classifies transistors designed for electronic applications that operate at frequencies of 30 MHz or higher. This includes a broad range of semiconductor transistors, such as field-effect transistors (FETs), bipolar junction transistors (BJTs), and insulated-gate bipolar transistors (IGBTs), when their intended or demonstrated operational frequency meets or exceeds this threshold. These components are fundamental to high-frequency circuits used in telecommunications, radio frequency (RF) applications, and advanced computing.

This classification distinguishes itself from other "Other" transistor categories by the critical parameter of operating frequency. While other subcategories within 8541.29.00 might cover transistors with different operating characteristics or for general-purpose use, 8541.29.00.75 is exclusively for those engineered and identified to function reliably at 30 MHz and above. It is important to note that this category is a leaf node, meaning there are no further subdivisions beneath it. Therefore, the classification hinges entirely on the technical specification of the operating frequency.
