LGGW6221MELB25

The LGGW6221MELB25 is a snap‑in terminal aluminum electrolytic capacitor offering 220 µF capacitance at a 420 V rating. Designed as part of Nichicon's LGG series, it targets general‑purpose high‑voltage applications that require compact size, reliable high‑temperature performance and robust ripple handling.

Key attributes include a -25°C to 105°C operating range, 2000 hours endurance at 105°C, snap‑in radial can packaging (φ30 × 25L mm), and RoHS compliance—making it suitable for power filtering, energy storage and smoothing in 400 V‑class systems.

Key Features

• Electrical Specification — 220 µF nominal capacitance with a rated voltage of 420 V and capacitance tolerance ±20% (at 120 Hz, 20°C).
• High‑temperature Endurance — Rated for 2000 hours at 105°C under D.C. bias plus rated ripple current; capacitance change remains within ±20% after endurance testing.
• Operating Temperature Range — Specified for operation from -25°C to 105°C for the 400–450 V rating range.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure mechanical retention in power assemblies; package described as Radial, Can – Snap‑In with dimensions φ30 × 25L mm.
• Ripple Current Capability — Rated ripple current: 950 mA at 120 Hz and 1.359 A at 100 kHz, supporting smoothing under both low‑ and high‑frequency ripple conditions.
• Leakage and Loss Characteristics — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ maximum for 160–420 V range is 0.15 (measured at 120 Hz, 20°C).
• RoHS Compliant — Meets RoHS directive requirements noted for the LGG series.

Typical Applications

• High‑voltage power filtering — Bulk smoothing and decoupling in 400 V‑class power supplies where 220 µF at 420 V and high ripple capability are required.
• Energy storage and hold‑up — Short‑term energy buffering and DC link support in general‑purpose power conversion equipment operating up to 420 V.
• Industrial power assemblies — Filtering and smoothing in industrial power modules and assemblies benefiting from snap‑in mounting and 105°C endurance.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in 400 V‑class circuits without overrating components.
• Compact, space‑efficient form factor: φ30 × 25L mm radial, snap‑in can provides a smaller footprint for designs constrained by board area and height.
• Designed for elevated temperature operation: 2000 hours at 105°C under load provides predictable long‑term performance in hot operating environments.
• Robust ripple handling: Specified ripple current at both 120 Hz and 100 kHz supports a range of switching frequencies and filtering tasks.
• Controlled leakage and dissipation: Leakage current limit I ≤ 3√(C·V) µA and defined tan δ limits support stable behavior and predictable power loss.
• RoHS compliance: Meets environmental directive requirements called out for the LGG series.
