# Supercap maximum current rating

I'm designing the power circuit for the $V_{BAT}$ portion of an STM32 microcontroller, using a supercap to hold the charge when the main is off.

I was calculating which resistor I should charge the supercap through, but I stumbled on the specifications:

What is the meaning of the MAX current at 30 min. column ? It does not seem to be the absolute maximum rating.

The capacitor charging current will drop exponentially, but I don't know from these specifications if it can withstand 150mA for 10-20 seconds when charging the capacitor from 0V.

The capacitor case is can-like with a diameter of ~17mm, and the specs does not specify power ratings for the case.
