Vishay Intertechnology has announced the launch of a new series of screwjoint aluminum electrolytic capacitors, 202 PML-ST, which allows designers to store higher energy in smaller Spaces. Available in 11 small package dimensions from 35 mm x 60 mm to 90 mm x 220 mm, Vishay BCcomponents 202 PML-ST series capacitors offer higher capacitance/voltage (CV) values than previous solutions, and up to 49.6 A for +85 °C, ESR as low as 2 mW and service life up to 10,000 hours.

     The electrolytic capacitor is a cylindrical aluminum casing with blue sleeve insulation, seal disc with pressure relief device, and has a rated voltage of 200 V to 450 V and a high volume/high voltage combination of 56 000 µF to 15 000 µF. For example, the 2200µF/400 V rated CV device, which previously came in a 65 mm x 105 mm package, now comes in a 50 mm x 105 mm package. Capacitor ripple current and ESR are superior to previous generation solutions similar to contour size rated CV devices. For example, a 4700µF/400 V rated CV device increases ripple current by 12% and reduces ESR by 16%.

     As polarised aluminium electrolytic capacitors using non-solid electrolytes, the device meets the RoHS standard and is particularly suitable for a wide range of pulsed power filtering, buffering and energy storage applications requiring a service life of 10 to 15 years. Typical end products include industrial motor drives, train and subway railway traction, welding machines, HVAC (heating, ventilation and air conditioning), UPS, wind turbines and photovoltaic inverters, medical X-ray machines.
