Intertechnology Inc. has introduced a series of 4-terminal, snap-in power
aluminum capacitors with voltage ratings from 350 V to 450 V and a long useful
life of 10,000 h at + 85 °C in 17 large case sizes.
The 095 PLL-4TSI capacitors feature a
cylindrical aluminum 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 aluminum electrolytic capacitors
with a nonsolid electrolyte, the 095 PLL-4TSI devices are well-suited for
DC-link capacitors on the main side of switch mode power converters. Focus end
products include solar inverters, motor drives, and uninterruptible power
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.
