Overview of LGG2G821MELC45 – Snap-in Aluminum Electrolytic Capacitor, 820 µF / 400 V

The LGG2G821MELC45 is a Nichicon LGG series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It provides 820 µF capacitance at a 400 V rating and is designed for general-purpose equipment that requires compact high-voltage bulk capacitance.

Built for elevated-temperature operation and long life, this capacitor is rated for operation from −25 °C to +105 °C with a proven endurance of 2000 hours at 105 °C. The part is RoHS compliant and produced for mass production with tray packing.

Key Features

  • Capacitance & Voltage — 820 µF nominal capacitance with a 400 V rated voltage suitable for high-voltage DC applications.
  • Tolerance & Polarization — Capacitance tolerance ±20% and polarized design for correct orientation in DC circuits.
  • Thermal & Lifetime — Operating temperature range −25 °C to +105 °C and endurance specified as 2000 hours at 105 °C under rated conditions.
  • Package & Mounting — Snap-in terminal, radial can package (φ35×45L) for secure PCB mounting and mechanical stability.
  • Ripple Current — Rated ripple handling of 2 A at 120 Hz and 2.86 A at 100 kHz, supporting both low- and high-frequency ripple conditions.
  • Size — Compact dimensions: L: 4.5 cm × D: 3.5 cm (φ35×45L), aiding equipment downsizing within the LGG series footprint.
  • Compliance — RoHS compliant as declared by the manufacturer.

Typical Applications

  • General-purpose electronic equipment — Provides high-voltage bulk capacitance for a wide range of general-purpose systems requiring reliable DC energy storage.
  • High-voltage DC circuits — Rated at 400 V for use where elevated DC voltage handling is required.
  • Elevated-temperature installations — Suitable for equipment operating up to 105 °C, backed by a 2000 hour endurance rating at that temperature.

Unique Advantages

  • High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without the need for multiple lower-voltage parts in series.
  • Compact snap-in package: φ35×45L radial can with snap-in terminals delivers a space-efficient, mechanically robust mounting solution for mass-production assemblies.
  • Designed for elevated-temperature service: Endurance specified at 2000 hours at 105 °C ensures predictable behavior in hotter operating environments.
  • Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 100 kHz support designs with both line-frequency and high-frequency ripple components.
  • RoHS compliant: Conforms to RoHS requirements for regulatory and environmental compatibility in commercial and industrial products.
  • Series pedigree: Part of Nichicon’s LGG series, offering a smaller case option within the series for equipment downsizing strategies.
