I need to install a capacitor in series with the primary winding of a high frequency transformer working at around 100 KHz.
The purpose is clear, to prevent core saturation due to flux walking.
The calculated value comes out to be around 10 to 15uF and 16V.
NP0 capacitors are expensive for the values given above. I am thinking to use X7R instead.
However, some vendors prohibit the use of X7R in AC configuration, while others provide softwares which show the maximum AC current allowed through a capacitor for a given capacitance and case size. The only restriction imposed is due to the temperature rise.
Does anyone have experience with X7R capacitors used in AC application. Are they safe for AC?
Please share our experiences...
Thanks!
