Cornell Dubilier (CDE) DGH and DSF 3-Cell Supercapacitors offer higher voltage and greater power density, along with ultra-fast charging, an extremely low self-discharge rate, and low equivalent series resistance (ESR). These compact modules are PCB mountable and feature internal cell balancing to deliver optimal performance and serve as a production time saver. The supercapacitors provide greater energy potential and power output than single- or dual-cell parts in standard PCB layouts, and multiple devices can be banked for even higher voltage or capacitance. CDE DGH and DSF 3-Cell Supercapacitors withstand more than 500,000 charge/discharge cycles, performing for up to 10 years without degradation. Applications include green energy, smart electric meters, pulse power, asset tracking, small electric vehicles (EVs), and the Internet of Things (IoT).
