Recently, Vishay Intertechnology, Inc. announced that it will extend the service life of 500V devices in the 159PUL-SI series of snap-on aluminum capacitors to 5000 hours. Vishay BCcomponents' capacitors are suitable for solar inverters, industrial motor control and power supplies with a lifetime of up to 5,000 hours at +105 °C.
The 159PUL-SI capacitors are housed in a cylindrical aluminum housing with a pressure reducing valve insulated from a blue sleeve and available in a variety of sizes from 22x25mm to 35x60mm. The device is rated from 200V to 500V with a ripple current of 2.80A, a maximum ESR of 150mΩ at 100Hz and a maximum operating temperature of +105°C.
The 159PUL-SI family of devices is a polarized aluminum electrolytic capacitor with a non-solid electrolyte that is ideal for smoothing, filtering and energy storage in pulsed power applications. Capacitors are RoHS compliant and come with a snap-on version with keyed polarity.
