Group buy: DCT03 DC trap (filter) for toroidal transformers
 
1 Attachment(s)
I have made a bigger DC filter for getting rid of the hum in big toroidal transformers. The pcb has 105 um copper and more than 1 cm wide traces. If the interest is big enough I will go ahead with a group buy. The diode package can handle 12 amps and 68000 uF/16 V caps will fit. This pcb is perfect for those who like it big.

I see that I have got some boards in interest. Let's hope we reach the set goal.

The interest is increasing. That's good.

Under what conditions (or VA rating) would the ~03 version be preferred over the ~02?

Some people want simply more and in case you have more than 6 amps you will also need it.

The DCT02 has 6 amp diodes so this could be a practical limit but for 110 V countries this could be a bit low but since you can add more capacitance you will get a very good current capability plus that the diode chain can handle more. I have four diodes in series so the DC limit is also increased.

Hmmm would be interested too

Don't forget to sign the list.

Will do tomorrow
