New Screw Terminal Aluminum Capacitors Offer 10% Higher Capacitance and Better Ripple Current Handling

Vishay Intertechnology released a new series of miniaturized screw terminal aluminum capacitors that deliver 10% higher capacitance and 10% better ripple current handling for a given can size than previous-generation devices allows designers to pack more energy storage into less space. The new Vishay BCcomponents 501 PGM-ST series devices comes in different rated voltages of 400 V, 450 V, and 500 V and capacitance values from 1000 µF to 18 000 µF. The capacitors offer a high rated ripple current to 30.2 A and a useful life of 5000 hours, both at + 85 °C. These features make the capacitors an ideal solution for applications and end products, including motor drives, HVAC, welding inverters, UPS, X-ray equipment, microgrid interfaces, wind turbines, and scientific test equipment.

 

The 501 PGM-ST series devices features a cylindrical aluminum case insulated with a blue sleeve and pressure relief in their sealing disc. The 501 PGM-ST capacitors are polarized aluminum electrolytic capacitors with a non-solid electrolyte which makes it an ideal choice for applications that demand high energy storage in a small form factor. Also, the 501 PGM-ST capacitors comes with 500V rating which provides increased voltage headroom in motor drives, UPS, and solar inverters by allowing three-phase, 380 V designs to be re-used in 480 V systems by simply upgrading the DC-Link capacitors and enables solar inverter systems to be upgraded for 1000 V maximum input.
