SECH is the quality manufacturer for supercapacitors (Supercaps).

A supercapacitor, also called a supercap, ultracap, boostcap, and ultracapacitor, is a high-capacity capacitor with a much higher capacitance value than other capacitors but with lower voltage limits that bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and release charge much faster than batteries, and can tolerate many more charge and discharge cycles than rechargeable batteries.

MASORI and SECH have collaborated to create supercap modules that have optimum dielectric strength for a Carhifi, have extremely high capacitances of several hundred farads, and are supplied ready for connection.
