We make & sell cable-based-Capacitors
Capacitech was launched to spin out technology from the University of Central Florida. Funded by the National Science Foundation SBIR/STTR program, our focus is currently on Cable-Based-Capacitor (CBC) technology. The CBC's unique form factor offer's a variety of advantages to distributors, designers, and manufacturing companies.
About the CBC Process
Why use CBC Technology?
The CBC is a new type of Capacitor which is built on the surface of a wire. This unique form factor provides many new advantages.
We sell you a spool of CBC wire. The performance of the CBC can be easily customized to meet new demand curves by cutting the wire at different lengths. Don't worry, markings on the wire make it easy. The CBC significantly simplifies ordering and helps you offer the lowest lead times on the market.
For Electronic Distributors
For Electronic Designers
The CBC is thin, tough, and flexible. Need to make a connection blocked by another copper trace? The CBC can connect on different ends of the PCB if needed. Need to fit a large capacitor inside a small case? Fold the CBC in half. Don't have room for a capacitor that is needed? Put it in the power cord!
For Electronic Manufacturers
By using less space on the PCB, the CBC can increase the speed of manufacturing and inspection processes! Better yet, thanks to significantly reduced lead times by being easily customized you can offer faster turn arounds and won't have to wait as long for inventory to arrive improving cash flow.
Capacitors come in so many shapes and sizes of a variety of different performances. With energy storage chemicals sandwiched between two concentric electrodes, the CBC is the first capacitor built in the form factor of a wire or cable.
The CBC's voltage and capacitance can be easily customized by the electronics distributor, manufacturer or designer, leading to flexibility and reduced lead times. It is thin, flexible, features an ESR of ~0.2 ohms, retains its charge with a leakage current of ~0.3mA, has a temperature range between +10 to +65 degrees Celsius, and offers a traditional capacitor response to varied frequencies.
The CBC can be used like a super capacitor or a traditional electrolytic capacitor. It all depends on the specifications you need and order from the distributor.

CBC as Backup Power
We charged 10cm long CBC devices connected in series for 1minute using a DC source providing constant voltage.
The CBC was then discharged in a standard DC electric motor rated to 9V.
As shown in the video, the CBC was able to provide about 1minute of power to the load proving it is a capacitor by nature in the form of a cable.
The CBC could discretely provide backup power to a variety of devices such as Wi-Fi routers, cable boxes, game consoles, IT equipment, electric bikes, or even RAM cards.

Frequently Asked Questions
Q: Can the CBC be a surface mount device?
A: No. It can be soldered onto a surface mount pad if needed. There is not room in the budget at this time to develop robotics that would be needed to make the CBC a surface mount device. The CBC is designed to replace capacitors with a large capacitance value which are typically large in size, through-hole, and often still installed by hand. The CBC is intended, at this point, to replace capacitors in the uF and mF range. Surface mount compatible capacitors are often in pF range which would be too small for the CBC.
Q: Why can’t you sell the CBC directly to end users? Why sell to electronic distributors?
A: End users typically buy long lists of bill of materials (BOMs). Purchasing managers prefer to be able to buy the required components from the same single source distributor. This is a tactic to simplify logistics. Mouser & DigiKey are very popular for our target market of small and medium size OEMs.
Q: How many capacitors can you replace in respect to the market? What fraction can you cover?
A: The CBC is currently rated for 3.2V and 40mF per cm. This size capacitor would be compatible to replace and add advantages to approximately 1/8 of the capacitors on market. At this stage, it is a niche market, however many industry experts have urged us to launch this product to get it out there and generate revenue while developing a CBC rated to 50V which would be capable of replacing about 1/3 market. In the pF range, the resolution of capacitors is higher (i.e 1pF, 2 pF, 3 pF, etc…) whereas the uF and mF range the resolution is lower (i.e 10uF, 100uF, 320uF, 680uF, 820uF, etc…)
