Overview of LGG2Z821MELZ40 – 820 µF, 180 V Ultra-Smaller Snap‑in Aluminum Electrolytic Capacitor, 105°C

The LGG2Z821MELZ40 is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general‑purpose electronic use. It delivers 820 µF at 180 V in an ultra‑smaller-sized LGG series case that is one rank smaller than the LGN series, making it suited for equipment downsizing.

Key value propositions include high operating temperature capability up to 105°C, defined endurance and shelf life characteristics, and snap‑in mounting for secure PCB installation—offering a compact, reliable energy storage component for demanding system environments.

Key Features

  • Electrical Capacity — 820 µF rated capacitance at 180 V, with a tolerance of ±20% (120 Hz, 20°C), providing defined bulk energy storage for power circuits.
  • High‑Temperature Operation & Endurance — Operating temperature range of −40°C to +105°C and endurance specified as 2000 hours at 105°C under DC bias plus rated ripple current.
  • Compact Snap‑in Package — Snap‑in terminal, radial can construction in an ultra‑smaller LGG series case (one rank smaller than LGN) for space‑constrained designs.
  • Ripple Current Capability — Rated ripple handling of 2 A at 120 Hz and 3 A at 100 kHz, enabling effective smoothing under AC/ripple conditions within specified limits.
  • Reliability Parameters — Leakage current meets I ≤ 3√CV (µA) after 5 minutes at 20°C; endurance and shelf‑life characteristics (including 1000 hours at 105°C storage conditions) ensure predictable performance over time.
  • Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

  • General‑purpose power circuits — Provides bulk capacitance and filtering where 820 µF at 180 V is required for energy smoothing or decoupling in electronic equipment.
  • Equipment downsizing — The LGG series' one‑rank smaller case size supports compact power supply and system designs that need reduced board area without changing capacitance or voltage rating.
  • High‑temperature environments — Suitable for assemblies that operate across −40°C to +105°C and require components with defined endurance at elevated temperatures.
  • Snap‑in PCB assemblies — Snap‑in terminal and radial can package simplify secure through‑hole mounting for robust mechanical retention on the board.

Unique Advantages

  • Space‑efficient design: One rank smaller case sizing enables tighter layouts and system miniaturization while maintaining required capacitance and voltage.
  • Designed for elevated temperatures: Rated to +105°C with a 2000‑hour endurance specification for reliable performance in hot operating conditions.
  • Defined ripple handling: Specified ripple current ratings at 120 Hz and 100 kHz provide clear design limits for thermal and electrical budgeting.
  • Robust mounting: Snap‑in terminals and radial can construction give secure mechanical attachment for through‑hole boards and power modules.
  • Predictable electrical characteristics: Specified leakage current, tan δ limits, and capacitance tolerance support repeatable designs and easier validation.
  • RoHS compliant: Meets EU RoHS directive requirements for environmentally conscious product design.
