Electrolytic capacitors
9 November 2016
Passive Components
Kemet announced six new families of surface-mount and through-hole conductive polymer aluminium solid electrolytic capacitors, with voltage ratings up to 250 V d.c. Leveraging the company’s latest high-conductivity polymer, the new devices have very low equivalent series resistance (ESR) resulting in low self-heating and high ripple-current capability.
The high ripple current capability allows these new devices to replace arrays of multiple conventional electrolytic capacitors connected in parallel, thereby enabling designers to save PCB real estate. In addition, the new families deliver enhanced reliability by giving ten times longer life for every 20°C reduction in operating temperature.
The through-hole devices cover capacitance values from 2,2 to 1500 microfarads, in four families that give designers a choice of properties including 2,5 - 250 V d.c. operating voltage range, extended lifetime of up to 5000 hours, and -55°C to 125°C specified temperature range.
The surface-mount families feature operating voltage up to 50 V d.c., specified temperature range of -55°C to 105°C, rated lifetime of 2000 hours, and capacitance values between 10 and 2700 microfarads.
