High Voltage Ceramic “Door Knob” Capacitors
All new, high quality, high voltage ceramic capacitors for voltage multipliers and other high voltage applications. These capacitors can be operated in open air for up to their full rated voltage.

These grades of ceramic used as the dielectric come in several forms regarding dissipation factor, frequency of operation and temperature coefficients. The capacitors that we sell on our site use two groups of dielectric. The best dielectric being N 4700. This you often seen written on the capacitor and is a positive figure of merit. This material has a very low dissipation factor of .1% and at the same time can operate up to 250 kHz. It has an insulation resistance of > 200000 meg-ohms! Unfortunately this material when used in high-voltage capacitors is very difficult to use if the capacitance is over several thousand pico-farads.

So the next grade which is a step down from the N4700 is the rating Y5T that you will often see with higher capacitance values of this type. This rating has a dissipation factor of 1% and a frequency of operation of around 100 kHz. It has an insulation resistance of > 100000 meg-ohms. This material is acceptable in many applications involving voltage multipliers and circuits where the oscillation frequency is below 100 kHz

The next material that we seldom use isY5V with a dissipation factor of >2% and an operation frequency 10000 meg-ohms. These are used in some of our low cost, low power voltage multiplier circuits

It should be noted that like any other electronic component that has a voltage rating, is usually the maximum value the component should be used for. A good engineer when designing a circuit especially using high-voltage components will always leave a margin of safety in the rating of the components used. This is often good practice with high-voltage parts as many of these are sealed in epoxy and other material that makes it virtually impossible to repair the actual defective part and the whole assembly must be replaced. This is cumbersome and costly. A possible way to limit this type of breakdown is to rate capacitors used in high-voltage circuits at 50% to 75% of their rated value. This is normally what our engineers do with our products yet every once in a while you still will have a failure. But that is the nature of high-voltage.


N4700 MURATA "Doorknob" capacitor
Operates at full voltage rating in air, no potting required. Very low dissipation and ideal for RF applications. Easily paralled for doubling energy and reducing discharge inductances. High quality capacitor is excellent for small Marx impulse generators and most high voltage projects. These capacitors are the result of our buying out another small business -- they are unused, but may have some cosmetic blemishes. We use them ourselves in our higher power HV series power supplies up to 300KV at 30mA, and in our nanosec Marx impulse generators.

High Capacity Ultralow Inductance High Voltage Capacitors
These strontium titanate capacitors are excellent for high frequency and fast discharge. They provide very low inductance with physically short distance from terminals. Stores from 9 to 12 J in a disk with recessed 10-32 threads (axial terminals add about 0.2" to overall height). We are currently working on an impulse generator for a government agency with the project name “Super Marx.” The assembly uses these caps and our patent-pending spark switches (more on this later as our unit gets some press).

These compact capacitors have the property of very high storage energy to volume ratio. They can be used for high current single event discharges if certain precautions in circuit design are implemented. Small rail, reconnection, coil, gauss, quench and reluctance guns can be constructed with appreciable velocity and yet still be hand held with properly designed systems. They are also used for small pulsed lasers using Ruby, Neodynium, Yag and other types laser rods. Note our LAGUN40 .

Specialized Capacitors for High Power Tesla Coils
These highly reliable capacitors are for museum displays, research, and professional applications where reliability is a premium. There are lower cost alternatives that use MMC and other options for this part, and these less costly choices are perfectly suitable for the hobbyist and experimenter. But when reliability matters, these are the capacitors to use.
Capacitor

These specialized capacitors are made for Tesla coil applications where high frequency and high current operation is required.

Capacitors are constructed with a polypropylene dielectric being specially wound to reduce corona and have a high voltage standoff capability. Capacitors are also designed to withstand the multiple discharges of a rotary gap system of up to 600 breaks per second with a suggested operating frequency of 30 kHz.

Capacitors are enclosed in a high impact PVC tubing and epoxy sealed. Terminations are via appropriate sized studs axially positioned. Our standard value is .05 ufd at 20 kvac (but others are available). This value provides an excellent combination when used with the readily available 14.4 kvac pole transformer in the 7 to 10 kva range. One capacitor will utilize one half this kva range while two in parallel with utilize the full rating and produce in excess of 10 foot discharges. (We use the .01u/10KVAC capacitor in our BTC30 tesla coil, and the .015u/12KVAC capacitor in our BTC40 tesla coil.)

Capacitors are enclosed in a high impact PVC tubing and epoxy sealed. Terminations are via appropriate sized studs axially positioned. Our standard values are shown and in stock most of the time. Many other values are available; please contact us if you need a specific design for a custom coil or other application.

We used a combination of these very specialized pieces in a contract that involves pre-detonation of IEDs and other similar devices showing proof of concept.

TESTING AND COMPARING THE CDE and the AMAZING1 CAPACITORS
Our .15ufd 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 and greatly improves the 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.
