These cutting-edge capacitors use a three-cell package for higher operating voltages and printed circuit board space savings.
The new supercapacitors offer a notable jump in voltage rating over typical radial-mount supercapacitors, up to 9.0 WVDC. A key feature of the DGH and DSF Series additions is the unique three-cell radial-leaded package. Compared to single or dual-cell supercapacitors, the compact design saves space and allows for much higher operating voltages, making them ideal for a wider range of applications. Both series include capacitance values from 0.33 to 5 Farads. Multiple devices can be banked for even higher capacitance or voltage.
Another notable advantage of these supercapacitors is their internal cell balancing. This feature ensures optimal performance and serves as a production time saver. DGH and DSF Series three-cell supercapacitors are also more cost-effective than other options currently available.
From a performance standpoint, both series offer high energy density and extremely low self-discharge rates, benefiting energy-storage applications. Both series are also tolerant of wide-ranging operational environments, with operating temperature ranges from -40 °C to +65 °C for DGH 8.1V/DSF 9.0V and -40 °C to +85 °C for DGH 6.9V/DSF 7.5V. Low Equivalent Series Resistance (ESR) minimizes energy loss for high efficiency. ESR varies by part but is lower than most capacitors with similar storage capabilities. These supercapacitors are designed to withstand over 500,000 charge/discharge cycles, ensuring long-lasting performance without performance degradation. Operating life is expected to be up to 10 years.
Like other supercapacitors offered by CDE, the new devices provide very fast power discharge that cannot be matched by conventional capacitors or batteries. That large capacity makes it possible to back up brief power interruptions, supplement batteries, or even be used in place of batteries in many applications. Applications include: solar and wind-energy harvesting, mechanical actuators, AGV (Automated Guided Vehicles), EV transportation power, smart utility meters, IIoT, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting or anywhere that significant energy storage is needed.
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.
Type MYH series of Y2, EMI/RFI suppression capacitors are designed for harsh environments. The MYH series is AEC-Q200 qualified, meets a 2,000-hour THB (Temperature, Humidity, Bias) life test, and has applications in motors, AMR (Automated Meter Readers), UPS, power supplies, charging systems, and appliances. These Y2, line-to-ground capacitors filter out electromagnetic noise and have multiple international safety agency approvals.
The MXH series is AEC-Q200 qualified, meets a 2,000-hour THB (Temperature, Humidity, Bias) life test, and has applications in motors, AMR (Automated Meter Readers), UPS, power supplies, charging systems, and appliances. These X2, across-the-line capacitors filter out electromagnetic noise and have multiple international safety agency approvals.
