Note 1 : This is the maximum current rating while all pins are powered or used as all power lines.
If you split the current over multiple lines, please factor in your own safety margin. Please contact Hirose Electric for
inquiries on the assignment of pins and on the currents that can be delivered.
Note 2 : Includes temperature rise caused by current fl ow.
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.
