Erse Super Q 5.0mH 16 AWG 500W Inductor

This is an awesome inductor for ultra low DCR, and it's got some serious heft to it too. I've found that hot melt glue mounted it just fine (I turned the MDF it was glued to upside down and hit the back of the board and it stayed on). If you want to go even crazier, you can use screws on these because they have pre drilled holes for them.

My only complaint is the color. I know no one ever sees them, but the picture shows a RED inductor, mine was green. I can't really see this being a problem unless you mount the XO outside or behind plexi, but I was still suprised when I got it.

My iron core was also an Erse, and it was red though.
