LGC2H221MELZ50

The LGC2H221MELZ50 is a snap‑in terminal, large‑can aluminum electrolytic capacitor from Nichicon’s LGC series, rated 220 µF at 500 V. It combines high voltage capability with a compact φ22 × 50 mm can size to support space‑conscious power designs.

Designed for general‑purpose power applications, the part delivers long life and reliable ripple handling for equipment downsizing and robust operation across −40°C to +105°C operating range.

Key Features

• Electrical Capacity: 220 µF nominal capacitance with tolerance −20% to +20% at 120 Hz, 20°C.
• High Voltage Rating: Rated voltage 500 V for high‑voltage power conversion and filtering.
• Ripple Performance: Low‑frequency ripple current 1.4 A (120 Hz) and high‑frequency ripple current 2.002 A (50 kHz), supporting DC bias plus rated ripple operation.
• Low Loss: Tangent of loss angle (tan δ) 0.25 max at 120 Hz, 20°C for predictable dissipation characteristics.
• Long Life Endurance: 5000 hours at 105°C (with DC bias plus rated ripple current applied) per LGC series long‑life assurance.
• Leakage Current: Specified leakage current approximately 990 µA after rated voltage application (per part table value 0.99 mA).
• Operating Range & Reliability: Rated for −40°C to +105°C and designed to meet stability and endurance requirements defined for the LGC series.
• Package & Mounting: Snap‑in radial can, size φ22 × 50 mm, supplied in tray packing for board‑level assembly.
• RoHS Compliance: Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies and converters: Bulk energy storage and smoothing in high‑voltage AC/DC and DC/DC power stages where 500 V rating and high ripple capability are required.
• Industrial power equipment: Filtering and decoupling in industrial systems that require long‑life capacitors rated to 105°C and robust ripple handling.
• Equipment downsizing projects: Compact φ22 × 50 mm can size and LGC series one‑rank smaller case option make it suitable where board space reduction is a priority.

Unique Advantages

• High‑voltage capability: 500 V rating enables use in demanding power circuits without series stacking or additional components.
• Compact high‑energy density: 220 µF in a φ22 × 50 mm snap‑in can supports space‑constrained designs while retaining large‑can benefits.
• Long operational life: 5000 hours at 105°C under rated conditions provides predictable aging and reduced maintenance intervals.
• Robust ripple handling: Specified ripple currents (1.4 A at 120 Hz, 2.002 A at 50 kHz) help maintain stability under continuous AC superposition on DC bias.
• Board‑ready snap‑in mounting: Snap‑in terminals simplify secure mechanical and electrical installation for power assemblies.
• Regulatory readiness: RoHS compliance supports environmental requirements for global equipment deployment.
