Overview of LGW2D821MELB30 – Aluminum Electrolytic Capacitor, Snap-in, 200 V / 820 µF

The LGW2D821MELB30 from Nichicon is an aluminum electrolytic capacitor in a radial snap-in can designed for general-purpose power applications. It combines a high 820 µF capacitance at 200 V with a snap-in terminal package and polarized construction for robust bulk energy storage and smoothing.

Engineered for elevated-temperature operation, this part is specified for –40°C to 105°C and is built to withstand 3,000 hours of rated ripple-current operation at 105°C. It is RoHS compliant.

Key Features

  • Capacitance and Voltage — 820 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance for predictable bulk-storage performance.
  • Snap-in Radial Package — Snap-in terminal, radial can package for secure vertical chassis or PCB mounting and reliable mechanical retention.
  • High Ripple Current & Frequency Performance — Rated ripple current of 3.48 A at 120 Hz and 5.22 A at 50 kHz, supporting high AC stress applications across a broad frequency range.
  • Elevated-Temperature Endurance — Endurance specified as withstanding 3,000 hours of rated ripple current at 105°C, enabling prolonged operation under thermal stress.
  • Operating Temperature Range — Specified for –40°C to 105°C to cover a wide range of industrial and electronic environments.
  • Leakage and Dielectric Characteristics — Leakage current specified per I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ (loss tangent) max. 0.15 for the 200–400 V range, supporting stable electrical behavior.
  • Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

  • Power Supply Filtering — Bulk smoothing and decoupling in switched-mode and linear power supplies, leveraging 820 µF at 200 V and high ripple-current capability.
  • DC Link and Energy Storage — Bulk energy reservoir for DC-link circuits in power conversion modules where elevated ripple current endurance is required.
  • Industrial Electronics — General-purpose smoothing and transient support in industrial control equipment operating across –40°C to 105°C.

Unique Advantages

  • Long High-Temperature Endurance — Specified 3,000-hour endurance at 105°C under rated ripple current, helping maintain capacitance and leakage performance over extended elevated-temperature use.
  • High Ripple Capability Across Frequencies — Explicit ripple-current ratings at 120 Hz and 50 kHz provide clarity for designers working with both low- and high-frequency stress conditions.
  • Robust Mounting — Snap-in radial can simplifies mechanical installation for chassis- or board-mounted power assemblies.
  • Clear Electrical Limits — Leakage current and tan δ specifications allow predictable design margins for reliability and thermal management.
  • Regulatory Compliance — RoHS conformity supports use in products requiring restricted-substance compliance.
