I'm having problems hot swapping a powersource to my board due to the input capacitance, I have a big inrush current and hence I see arching (sparking) on the connector when I connect it to my board. I believe this could lead to damage down the line so I want to avoid it.
I tried NTC Thermistors to limit the inrush, they worked, but you suffer from the 120seconds reset time of the Thermistor.
This is the device in question:
This device limits the inrush current in a unique way, by creating a slow transition on the output voltage. But alas this is a very specialized device for military use, and hence must be very expensive, and also looks quite bulky.
Can you recommend a similar device but for commercial products? Or any other way to duplicate the behavior of this device?
Input source:
External Power Supply Brick. 24V DC
Steady State Current: 3A
Max Peak Current : 8A
