Default SPEEDPASSION Super Capacitor!

SPEEDPASSION new Super Capacitor

Super – Capacitor Single 3,000,000uf (for using on 4 Cell & Ratio Receiver)
Super – Capacitor Double 1,500,000uf (for using on 6 Cell)



Main Features of Super Capacitor:
One single “Super – Capacitor” with 3,000,000uf (+/-20%)
Provide high power for peak current loads (low ESR)
Store sufficient energy to enable powers surges (high capacitance)
Solve RF power limitations
Reduced Voltage drops
Reduce DC/DC requirements
Solve current limitations

SPEEDPASSION products are the result of pioneering super-capacitor research, materials expertise and superior production technologies. The Company teams with CSIRO, Australia’s largest research body, for world-class expertise in carbons, polymers, electrochemistry, and materials science, and partners with Invetech to utilize the innovative product and manufacturing processes.

SPEEDPASSION breakthrough technology makes it the first company to tailor its super-capacitors to achieve a wide and continuous range of time constants. Devices are produced over a wide spectrum of time constants (as related to response time) to suit specific applications with the right combination of high power and energy densities.
The SPEEDPASSION super-capacitor is a single cell rated at 2.25V. Each single cell device consists of layers in pairs. Dual cell devices are designed to meet specific customer applications and are rated at 4.5V.
The current product mix includes a range of 20 dual cell products with customized layers, two footprint sizes, and two electrolytes. This provides wide coverage of ESR, capacitance and size for wide range wireless, consumers and commercial applications.



Product Highlights
High capacitance of 10mF to 2.8F yields high energy density
Low ESR of 20 to 115 m W yields high power density
Small footprint of 28.5 mm x 17 mm for the W series and 39 mm x 17 mm for the S series
Wafer thin profile of 0.7 – 3.9 mm
Superior thermal characteristics — organic electrolytes with operating temperatures of -30 ºC to +75 ºC for the G series, and -30 ºC to +85 ºC for the H series
Light-weight packaging
Environmentally friendly

SPEEDPASSION Products: A Competitive Review
SPEEDPASSION is distinguished technologically by its ability to tailor its super-capacitors to a wide and continuous range of time constants. The Company can produce devices over a wide spectrum of time constants to meet the high power and high energy densities needs of a specific device. In comparison, competitors have very limited (usually slower) time constant technology and a restricted ability to produce a range of time constants. These factors translate into superior performance specifications.
In the following chart, the scale on both axes is logarithmic. In general, a product to the right and/or above another delivers superior performance. The highest performance quadrant represents the area defined by SPEEDPASSION latest, patented technology.

Comparison Chart
The following table gives a brief summary of some critical properties of each technology. Because there are so many types with widely different properties, battery values are shown as a range.

I have a Novak and a MMR one and I still can't tell the difference

This capacitor is super fast charge, we have test the Novak capacitor just touch 2 second on the full charge battery, then touch on the 19T motor installed in the car, the wheel just turn around 15 degrees. But we use this super capacitor same touch the battery 2 second, the wheel can turn 180 degrees, that's mean this capacitor CHARGE SPEED is very fast, this is difference.

Coming we will post the video to show it.

Standard capacitors charge quickly enough for our application. Don't be duped by this one folks...

definately easier to place on the esc or car chassis.
looks better than the cylinder type caps.

Interestingly enough, I was told by a pro driver that there is no need for a cap in any on road stock motor racing, and not much in 1/12 mod. Touring car mod is the only clas where you are off the gas long enough to take advantage of the cap. Has anyone had any experience with this?

It's a picture from the assembly line. Most likely a test stand to test / cycle / condition , etc. the capacitors.

Soes that mean that this capacitor will keep the voltage spikes down even better than a regular capacitor due to the fact that it takes in charge alot faster?

Maybe i am naive... or critical... and a non-believer in leaping technology... but I think this is too good to be true... a 3F capacitor... is 300x more than a 10,000 uF. It has the storage capacity of 300 of the largest capacitors I have ever used in RC...

Sorry that seems ridiculous to me.

I have never seen any capacitor with that kind of capacity except for in car audio .... and certainly they are not this size.

Like i said, i know these are low voltage capacitors... but still.... i have never heard of anything like this.

If the physics is avaliable online... i would like to understand the theory behind it more... please send me a link... I would love to get my professors to help me out with this one.

because if i understand this is a capacitor...
it should follow Q = CV and other conventional formulae... the area required to have this kind of capacitance....would be HUGE!

Sorry I am not normally like this... all bitter and such... but this does come to me as a shock.

hm... using some highschool/freshmen college physics and a few assumptions.... it is pretty hard to make i think.... but what do i know...?

assume:
- this is a typical parallel plate capacitor....
- separation between the plates is 1 um.
- dielectric constant is strontium titanate = 332 (largest i could find in my textbook...)

Through some calculations...
The area of the plates should be about 1km squared...

Assume:
- capacitor has an area of 2cmx5cm = 10cm squared
- the thickness of 1 layer of the capacitor is 2um.

1km^2 = 1,000 m^2 = 100000 cm^2 (maybe i am a wrong)
I will need 10000 layers of this to get 1km^2....
10000 layers of 2um thick gives 2cm.

So i am thinking a cap will have to be at least 2x2x5 cm to get 3F....

But is it possible to keep costs low and have these kind of specs?
(1um spacing in a capacitor with 2um layers? strontium titanate as a dielectric?)

Or is it because i am only a freshman college student and don't understand the finer details involved....?

I agree with RCZombies, easier to mount. Other than that it may help with spikes to the motor, easier on the com?
