Aluminum electrolytic capacitors: Compact snap-in series with significantly increased ripple current capability

  • Up to 25 percent higher ripple current capability than the preceding series
  • Extremely compact dimensions

TDK Corporation presents a new series of EPCOS snap-in aluminum electrolytic capacitors. They are characterized by a ripple current capability that is up to 25 percent higher than for the types of the preceding EPCOS series. The capacitors of the new B43642* series are manufactured in highly compact sizes with diameters ranging from 22 mm to 35 mm and heights of 25 mm to 55 mm.

These components are designed for rated voltages of 200 V DC to 450 V DC and cover a capacitance range from 82 µF to 3300 µF. Under continuous operation at 105 °C, the useful life of these capacitors is 3000 hours.

Applications of these new snap-in aluminum electrolytic capacitors are converters and power supplies for use in industrial electronics.
