Raptor Box Mod

[tumbafox]

Can anyone explain or post a diagram of how I attach the 2x22uf capacitors to the 120 watt naos raptor chip while assembling the box mod. These things are so tiny I'm freaking out

From what I can see you should solder them in parallel and the negative goes to ground on the board and the positive to the VIN pin. I would tin the legs and the pins and heat them a little till you attach them. after your done with wiring the board you can fold them out of the way.

Hope that helps

Do you know the answer

thanks. can i use 2 22uf electrolytic axial lead capacitors instead of the tiny caps i got from mouser

 

[david4500]

from raptor 20 amp data sheet:

"To minimize input voltage ripple, low-ESR ceramic or
polymer capacitors are recommended at the input of the
module."

I realize now what you were askin.g mamu uses the TDK caps. it has been a few years since i have worked with small electronics and when i seen those on the diagram and looked at them at mouser and the data sheet. i ordered the old style caps for mine also..

Yes you can use those caps they will work fine.

I lost my 220 Ohm resistor and was wondering is I could use a 200 pot set to 200 ohm with 1 outer leg attached to center the same as a 200 Ohm resistor. I will lose some wattage I suppose but isn't the Pot with outer leg connected to center leg and glued into position the same as a 200 ohm resistor. Thoughts anyone?

 

[tumbafox]

Can I use a 200 ohm rheostat instead of the 200 ohm pot since wiring either outer leg to the center the same anyway?

Can you go to a store like Radioshack and just purchase a 220 ohm resistor?

I see, you may use a 200 ohm pot and simply wire the outer legs and disregard the center leg. Doing so would give you the full 200 ohm resistance of the pot. A rheostat could also be used, just be sure that either can handle the correct power dissipation required. Either of these ways will just take up more space than normal resistor.
