The Fuji Electric 1MBI300U4‑120 is a powerful and efficient IGBT power module engineered for high-performance industrial power electronics. To purchase this part directly, visit https://www.uscomponent.com/buy/Fuji/1MBI300U4-120 through USComponent, the official Fuji Electric distributor. Buying from an authorized source ensures you receive a genuine, factory-authorized component with full documentation, proven traceability, and reliable support.

The 1MBI300U4‑120 is a rugged insulated gate bipolar transistor (IGBT) module rated at 1200V and 300A, making it ideal for applications that require both high voltage tolerance and substantial current capacity. This combination of electrical ratings enables designers and engineers to implement robust power switching and conversion solutions in systems where efficiency and dependability are critical.


Unlike lower-rated IGBT modules, the 1MBI300U4‑120 is especially suited for larger power systems because it handles high voltage stresses and significant load demands without compromising performance. Its advanced semiconductor design supports fast switching speeds with low conduction loss, improving operational efficiency and reducing unnecessary energy waste. These electrical characteristics are vital in applications where high throughput and reduced heat generation can improve overall system uptime and reliability.


Thermal management is an essential consideration in high-capacity power modules, and the 1MBI300U4‑120 is designed to maintain stable temperatures even under demanding conditions. Strong heat dissipation capabilities help protect both the module and surrounding components from thermal stress, which in turn can extend equipment service life and reduce the frequency of maintenance cycles.


Because of its high voltage and current specifications, the Fuji Electric 1MBI300U4‑120 is frequently used in heavy-duty power electronics environments. Typical applications include large variable frequency drives (VFDs), industrial inverters, renewable energy power conversion systems, traction drives, large motor control systems, and high-power welding equipment. These systems benefit from the module’s ability to handle large electrical loads while maintaining precise control and efficient performance.


Choosing Fuji Electric IGBT modules also means choosing a legacy of engineering excellence and manufacturing quality. Fuji Electric products are trusted by industrial professionals around the world for their consistent performance under stress and long operational life. Sourcing these components through an official distributor like USComponent adds further peace of mind, ensuring product authenticity and dependable availability.


For engineers, system designers, and procurement teams working on high-power systems, the Fuji Electric 1MBI300U4‑120 offers a balanced blend of electrical performance, thermal stability, and industrial robustness, making it a solid choice for demanding power control applications.
