Vishay Intertechnology has announced that its 500 V snap-in power aluminum capacitors for solar PV inverters, industrial motor control, and power supplies, now offer a useful life of 5,000 hours at +105 °C.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the 159 PUL-SI series devices are ideally suited for smoothing, filtering, and energy storage in pulsed power applications.
The 159 PUL-SI capacitors feature a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve. They are available in a variety of case sizes ranging from 22 x 25 mm to 35 x 60 mm.
The devices feature rated voltages from 200 V to 500 V, high ripple current to 2.80 A, maximum ESR down to 150 mΩ at 100 Hz, and a maximum operating temperature to +105 °C.
The RoHS-compliant capacitors are also available in a keyed polarity snap-in version.
Samples and production quantities of the 159 PUL-SI series capacitors are available now, with lead times of 12 to 14 weeks.
