4-terminal, snap-in power aluminium capacitors deliver 10,000-hours of useful life

July 16, 2010 // Julien Happich

Vishay Intertechnology launched a new series of 4-terminal, snap-in power aluminium capacitors with voltage ratings from 350 V to 450 V and a long useful life of 10,000 hours at + 85 °C in 17 large case sizes.

The 095 PLL-4TSI capacitors feature a cylindrical aluminium case insulated with a blue sleeve and pressure relief, while a four-terminal design provides increased mechanical stability and keyed polarity.

The devices are available in case sizes ranging from 35 mm by 50 mm to 45 mm by 100 mm. With larger case sizes than standard snap-in devices, the 095 PLL-4TSI series offers high capacitance/voltage combinations, from 390 µF at 450 V to 2,200 µF at 350 V, which until now have been normally offered only in capacitors with screw terminal terminations.

The 095 PLL-4TSI makes these combinations available for cost-sensitive applications where PC board mounting is done with a simple soldering process. The capacitors offer a high rated ripple current to 8.6 A at + 85 °C, and are lead (Pb)-free and compliant to RoHS Directive 2002/95/EC.

As polarized aluminium electrolytic capacitors with a nonsolid electrolyte, the 095 PLL-4TSI devices are suitable for DC-link capacitors on the main side of switch mode power converters. Focus end products include solar inverters, motor drives, and uninterruptible power supplies (UPS).

For applications where a 500-V rating is required, Vishay also offers the 096 PLL-4TSI series of 4-terminal, snap-in power aluminum capacitors. The devices offer a 350-V to 500-V rated voltage range, capacitance to 2,700 µF, and a useful life of 5,000 h at + 85 °C.
