Vishay 193 PUR-SI solar series capacitors
Vishay announces 193 PUR-SI solar series capacitors
Vishay Intertechnology, Inc. announced that it has upgraded the Vishay BCcomponents 193 PUR-SI solar series of snap-in power aluminum capacitors with a higher rated voltage of 570V and a category voltage of 475V. Targeted at solar applications, the devices offer operation up to 600V at specific conditions, long useful life, and high rated ripple current up to 2.46A at +105°C and 100Hz. At 570V, enhanced 193 PUR-SI solar series devices feature a maximum operating temperature to +60°C and endurance of 5000hours (no ripple current applied).
At 475V, the maximum temperature can be extended to +105°C, and the useful life is 6000hours. With their ability to fulfill the open-circuit voltage condition up to 600V, the components lower the overall cost of solar PV inverters by reducing the number of electrolytic capacitors required, allowing designers to use one capacitor for string input voltages of 600V and two for 1200V.
Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, 193 PUR-SI solar series capacitors are available in five case sizes ranging from 35mm by 30mm to 35mm by 60mm. As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the RoHS-compliant devices are ideally suited for DC-Link buffering and filtering applications. In addition to solar PV inverters, typical end products will include industrial motor controls and power supplies.
