Vishay’s 146 CTI series of aluminium electrolytic capacitors are ideal for energy storage, smoothing and filtering in applications requiring high ripple current, high-temperature capability and low impedance.
The 146 CTI low-impedance series, part of Vishay’s surface-mount family of aluminium capacitors, comprises devices which are capable of up to 6,000 hours’ useful life at 125°C. The whole series is AEC-Q200 qualified for use in automotive electronic-control units as well as industrial and professional applications.
The devices are vibration-proof, featuring four or six solderable pads, and are also charge and discharge-proof with no peak current limitation. The devices are also notable for their low equivalent series resistance.
Devices in nominal case sizes from 8mm x 8mm x 10mm to 18mm x 18mm x 21mm are available in voltage ratings from 16V to 100V and a capacitance range from 10μF to 4,700μF.
