Popular supercapacitor line expanded up to 600 Farads
CDE’s Illinois Capacitor brand DGH Series of supercapacitors has been its most popular to date, with a winning combination of low ESR and low cost. Now, the line has been expanded, with capacitance values up to 600 Farads. The DGH Series includes 24 different value/voltage combinations, ranging in capacitance from 0.5F (Farad) to 600F, with voltage ratings from 2.7 to 5.5WVDC. Operating temperature range of -40 ºC to 65 ºC at maximum WVDC, or from -40 ºC to 85 ºC at 2.3 volts. Multiple devices can be banked in parallel or series for even higher voltage or capacitance.
Because of their massive energy storage, DGH supercaps can discharge instantaneous bursts of power to smooth power interruptions, supplement batteries, or even be used in place of batteries in certain applications. Unlike batteries, DGH supercaps do not degrade with each cycle. At 2.7 volts, operating life is rated at 10 years with 500,000 charge/discharge cycles. Applications for these supercapacitors include: energy harvesting, IoT systems, mechanical actuators, transportation power, smart electric meters, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting and many other devices requiring maximum energy storage in a minimum of space.
Radial, two-pin snap-in, four-pin snap-in, and dual pack configurations in the series are available, depending on voltage and capacitance combinations. Likewise, case diameters and configurations vary, depending on values. Parts are also fully RoHS compliant. The DGH Series is available from stock at major distributors. Custom modules, with active or passive balancing, are also available, to meet higher voltage or capacitance requirements.
Highlights
Battery Backup/Alternative – Pulse Power – Energy Harvesting – LED Displays – Mechanical Actuators – Audio Systems
Type QAS will extend the operating life of electronic and electro-mechanical devices by reducing and/or eliminating the electrical arcing, noise, and EMF. These electrical conditions often cause early failures in relays, switch contacts, and solid-state components such as SCRs and TRIACs.
Three-cell devices offer greater energy potential and power output than single or dual-cell parts in standard PCB layouts
3-cell DSF & DGH capacitors provide very fast power discharge that cannot be matched by conventional capacitors or batteries. That large capacity makes it possible to support brief power interruptions, supplement batteries, or even be used in place of batteries in many applications.
Type MXT Series Metallized Polypropylene Film Capacitor, designed to suppress conducted electromagnetic/radio frequency interference (EMI/RFI) at a circuit’s power input. These capacitors are perfect for use in harsh environments having met the demanding 85/85 THB (Temperature, Humidity, Bias) test requirements. Class X2 capacitors, like the MXT, are typically connected across the AC input to prevent interference from spreading through power lines or other devices on the same circuit.
