AC Power Conditioning Thoughts?

[JamesDean59]

Hey guys, I was wondering what your thoughts on ac power conditioning were?

I've got to put an order into Mouser soon for some parts and recalled an article I came across a while about about installing AC suppression capacitors across outlet in a power strip..

I've got some DIY power stuff that my gear is all plugged into now, I figured it wouldn't be a bad idea to add some noise suppression capacitors.

The author didn't mention the part number on the capacitors or their value, the pic look like 250V but not sure about capacitance.

What are you thoughts on this stuff?

All I've ever used is a good Tripp/Lite power strip.

You must use safety capacitors.

X rated if they go across the power line and Y rated if they go from the power line to ground.

This is a must for safety.

The caps I was looking at are Vishay F1778, Class X2. Just wasn't sure what the best value for capacitance would be..

The ones in your 10audio link are 0.1uF. Be careful messing around with line voltage.

I'm very cautious when working with line voltage.

Would the be any motivation to move to a larger capacitance?

I found a document online discussing noise suppression on ac mains...

"Since,normal mode noise is low-frequency then,X capacitor values are 0.1~1.0㎌.
One would think that a capacitor with a larger constant should be used for suppression against normal-mode noise.
However,increasing the X-capacitor's capacitance causes a problem of increased reactive current"
