Intended for the hobbyist and applications with less stringent reliability factors. These capacitors were tested along with the equivalent CDE unit many builders are now using. We found no difference in performance or operation either for spark or the primary capacitor for DRSSTC high powered coils.
This is for 1 individual capacitor -- please adjust the quantity if you need more.
TESTING AND COMPARING THE CDE and the AMAZING1 CAPACITORS
Our .15mfd 2000volt metallized polypropylene film and film foil capacitors are built into a rectangular enclosure and fully potted. The value of this capacitor is identical to the Cornell Dubilier 942C20P15K-F. When tested against this part, it was found that they performed identically. There were no breakdowns in either capacitor when used in similar circuits. We than ran both capacitor modules by reducing the number in series and keeping the spark gap voltage the same (6000V RMS AC 60Hz 30mA), to find out when breakdown would occur. We did this with 10 units of each, and there was no statistical difference between this capacitor and the CDE in the breakdown and failure points. We were very pleased at the outcome and performance of these capacitors. NOTE that the volume of this capacitor is 50cm2, whereas the CDE is 31cm2.
MERITS OF OUR .15u/2KVAMZ1 CAPACITOR DESIGN
Our capacitors are built into a rectangular enclosure of PVC 4.3cm x 3.3cm x 3.5cm with a wall thickness in excess of 1/16 inch. They are completely potted with the leads exiting at the top of the epoxy very close to the ends. This makes it very convenient when attaching these capacitors in a series configuration by simply parallel connecting the 18 gauge leads, therefore doubling up on the conductance of the connections and greatly simplifying the attachment process. Furthermore the capacitors can be mounted on a flat piece of PVC or other substrate and do not require holes drilled and the long lead legs like when using the axial CDE capacitors. This in itself reduces the assembly time, quality and aesthetics of the completed module. Voltage balancing resistors are now easily connected to the assembly to finish it off. You have the option of gluing the capacitors in place or securing them with nylon tie wraps, tape, or similar. You can then parallel the rows: as an example, 15 capacitors can be mounted in series in three rows of five each and make for a nice compact good-looking package as seen in the photo.
