Overview

The EPCOS B43501-S9337-M3 is a long-life, snap-in aluminum electrolytic capacitor from the B43501 series, designed for demanding industrial applications. It features a 330µF capacitance and a 400V DC rated voltage, housed in a compact 30mm x 45mm case. This component is engineered for high ripple current capability, low ESR, and reliable operation in frequency converters, solar inverters, and power supplies.

Key Features

  • Long useful life grade, rated for >10,000 hours at 85°C and full rated voltage/ripple current.
  • High ripple current capability with low equivalent series resistance (ESR).
  • RoHS-compatible construction with charge/discharge-proof, polar design.
  • Snap-in solder pins (4.5 mm or 6.3 mm lengths available) for secure PCB mounting.
  • Overload protection via a safety vent on the capacitor base.
  • Available with PVC insulation, PET insulation, or PVC with an additional PET insulation cap.
