Vishay New Product Release – Aluminium Capacitors 202 PML-ST Series
New 202 PML-ST Series Screw-Terminal Aluminum Capacitors Provide High Capacitance / Voltage Combinations in Smaller Case Sizes, Offer High Ripple Currents Up to 49.6 A, Low ESR Down to 2 mOhm, and Long Useful Life to 10 000 h
The News:
Vishay Intertechnology introduces a new series of screw-terminal aluminum electrolytic capacitors that allow designers to pack more energy storage into less space. Available in 11 case sizes ranging from 35 mm by 60 mm to 90 mm by 220 mm, the Vishay BCcomponents 202 PML-ST series offers high capacitance / voltage (CV) values
in smaller case sizes than previous-generation solutions, while providing increased ripple current to 49.6 A, lower ESR down to 2 mOhm, and a long useful life of 10 000 h at +85 °C.
• Polarized aluminum electrolytic capacitors with a non-solid electrolyte
• With the 202 PML-ST series, a CV rating of 2200 µF / 400 V — previously available in the 65 mm by 105 mm
case size — is now available in the smaller 50 mm by 105 mm case size
• For CV ratings with a similar case size to previous-generation solutions, the capacitors offer improved ripple current and ESR. For example, a CV rating of 4700 µF / 400 V offers 12 % higher ripple current and 16 % lower ESR
Product Benefits:
• Available in 11 case sizes ranging from 35 mm by 60 mm to 90 mm by 220 mm
• Provide high CV combinations from 56 000 µF at 200 V to 15 000 µF at 450 V
• High ripple current to 49.6 A
• Low ESR down to 2 m
• Long useful life of 10 000 h at +85 C
• Feature a cylindrical aluminum case insulated with a blue sleeve and pressure
relief in their sealing disc
• RoHS-compliant
Market Applications:
• Filtering, buffering, and energy storage in pulsed power applications with a required lifetime of 10 to 15 years
• Typical end products include industrial motor drives; rail traction for trains and subways; welding equipment,
HVAC, and UPS; wind turbines and solar power inverters; and medical X-ray equipment
