Re: [TCML] Another MMC question.
Hi Michael, All,
I deleted that old MMC Cap Chart. I created another chart in the way "I"
would do it for the 0.15uF CD cap which is so common. The chart is good
only for that cap. I basically added Vp and Temp Rise for a given
transformer type and then added combinations to meet the value for
Resonant, Static LTR, and SRSG LTR.
The higher the voltage rating = the better the cap.
The lower the Temp Rise = the better the cap.
For a given NST type, I stopped when the MMC met or exceeded 2.5 x Vp
and if the temperature rise per cap in degrees centigrade was below 2
(when both conditions were met). In all cases, the temp rise is either
"good" or "excellent". It's the standoff voltage really that is of the
most concern with this particular chart.
Like I've said in the past, I don't use charts, but for those that
prefer a chart to get "as near as possible to stated LTR sizes", this
one should help (and if you can't understand if the string combo is good
or bad, then just ask the TCML). Due to the single cap value (0.15uF),
the "nearest" mmc value must be used. The old chart didn't really
explain that. With this chart, the value you see is the actual value of
the mmc. Just something I noticed while going through numbers on the old
This chart is 60Hz only. If there are "any" 50Hz coilers desiring the
same, just let me know. It's no big deal (but please ask while it's
still fresh in my brain).
