EMX4 / UMX4N / IMX4 are high frequency dual transistors produced by ROHM. Their maximum transition frequency can reach 1.5GHz and their output capacitance is only 0.9pF, which makes them show excellent performance in applications.
This datasheet presents the key specifications of the ROHM EMX4, UMX4N, and IMX4 bipolar transistors, including maximum voltage ratings, current limits, transition frequency, and package dimensions. It also includes equivalent circuit diagrams and typical electrical characteristic curves.
Additional notes describe usage guidelines, warranty limitations, and contact information for ROHM support. The document is intended for designers integrating these transistors into electronic equipment such as audio‑visual, communication, and consumer devices. This manual is written in Chinese.
