The Fuji 7MBR100U4B120-50 is a specific IGBT (Insulated Gate Bipolar Transistor) module designed and manufactured by Fuji Electric. This module is part of their 7MBR series and is commonly used in various high-power applications. Let’s break down the code and understand its specifications:
- 7MBR: This indicates the series or family of IGBT modules. The “MBR” likely stands for “Module Bipolar Transistor.”
- 100: This number represents the maximum collector current rating of the module, which is 100 amperes. It signifies the amount of current the module can handle without being damaged.
- U4: The “U4” code indicates the voltage rating of the module. In this case, “U4” likely corresponds to a voltage rating of 1200 volts. This means the module can handle voltage levels up to 1200 volts.
- B: The letter code “B” refers to the circuit configuration of the module. In this context, “B” might represent a specific configuration, such as a single-phase bridge.
- 120: This number indicates the current rating of the built-in temperature sensor, measured in milliamperes (mA). This sensor helps monitor the temperature of the module during operation.
- 50: The “50” represents the maximum operating junction temperature of the module, which is 50 degrees Celsius. This temperature limit indicates the highest temperature the module can safely operate at without risking damage
