LGG2D821MELA35

The LGG2D821MELA35 is an aluminum electrolytic capacitor from Nichicon’s LGG series, featuring a snap‑in terminal radial can in a compact φ25 × 35 mm package. It delivers 820 µF at 200 V with polarized construction and is designed for general‑purpose use in equipment where compact size and reliable high‑temperature performance are required.

Engineered for compact designs, this snap‑in, 105°C rated capacitor supports applications that demand bulk capacitance, ripple handling and long endurance under elevated temperature conditions.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 200 V, with tolerance ±20% (120 Hz, 20°C).
• Compact Snap‑in Package — Radial can, snap‑in mounting in a φ25 × 35 mm (3.5 × 2.5 cm) package for secure board installation and space‑efficient layouts.
• High Temperature Rating — Operating temperature range from −40°C to +105°C, supporting sustained elevated‑temperature operation.
• Endurance — 2000 hours at 105°C under DC bias plus rated ripple current while meeting the specified capacitance, tan δ and leakage current criteria.
• Ripple Current Capability — Rated ripple current of 1.75 A at 120 Hz and 2.625 A at 100 kHz for effective AC ripple handling in power circuits.
• Leakage Current Specification — Leakage current limited by the series formula I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C, enabling predictable standby losses.
• RoHS Compliant — Meets RoHS requirements, suitable for electronics manufacturing with lead‑restriction mandates.
• Series Design Advantages — Part of Nichicon’s LGG family, described as “105°C Ultra‑Smaller‑Sized” and one rank smaller case size than the LGN series, aiding equipment downsizing.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple suppression where an 820 µF, 200 V polarized capacitor is required.
• Compact power supplies — The smaller LGG case size supports equipment downsizing while providing required capacitance and ripple handling.
• Industrial and commercial electronics — Suitable for general‑purpose use in assemblies that demand long endurance at up to 105°C.
• High‑temperature environments — Provides stable operation within the −40°C to +105°C category temperature range specified for the series.

Unique Advantages

• Space‑efficient form factor — φ25 × 35 mm snap‑in can reduces board footprint compared with larger case options, supporting compact product designs.
• Designed for elevated‑temperature longevity — 2000 hours endurance at 105°C under DC bias plus rated ripple current offers predictable, long‑term performance.
• Measured ripple capability — Explicit ripple ratings at both low and high frequencies (1.75 A at 120 Hz, 2.625 A at 100 kHz) help match the component to real‑world power conditions.
• Predictable leakage behavior — Leakage limited by the documented I ≤ 3√CV formula, enabling straightforward thermal and standby loss calculations.
• RoHS compliance — Meets environmental restrictions for regulated markets and manufacturing flows.
• Snap‑in mounting for robust assembly — Radial snap‑in terminals provide secure mechanical attachment for mass production and automated handling.
