Note 1 : This is the maximum current rating while all pins are powered or used as all power lines. When isolating power lines
into multiple circuits, current ratings may go above the stated current ratings. Please consult Hirose for specifi c details
before doing this.
Note 2 : Includes the temperature rise of power lines.
Note 3 : The connector should be completely dry. (no condensation present)
Note 4 : The term “storage” refers to the long-term storage condition of unused products before PCB mounting. The operating
temperature and humidity ranges are applied while in a non-energized state, while in transport or after PCB mounting.
