LGN2G221MELZ45

The LGN2G221MELZ45 is a 220 µF, 400 V snap‑in aluminum electrolytic capacitor from Nichicon’s LGN series. It combines high‑voltage capacitance with a compact, snap‑in radial can package intended for general‑purpose power applications.

Designed for demanding thermal and ripple environments, this part offers a wide operating temperature range and rated endurance, making it suitable for power conversion and bulk energy smoothing where reliable high‑voltage filtering is required.

Key Features

• Electrical Performance — 220 µF rated capacitance with ±20% tolerance and a 400 V rated voltage for mid‑to‑high voltage designs.
• Ripple and Leakage — Low‑frequency ripple current 1.1 A (120 Hz) and high‑frequency ripple current 1.573 A (100 kHz); leakage current specified at 880 µA.
• Reliability & Endurance — Life rating of 3000 hours at 105 °C when subjected to rated ripple and DC bias, supporting sustained operation under elevated temperature and ripple stress.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.15 (measured at 20 °C, 120 Hz), providing predictable dissipation characteristics in AC environments.
• Package & Mounting — Snap‑in terminal, radial can package (φ22 × 45 mm), supplied in tray packing for PCB assembly and robust mechanical mounting.
• Operating Range — Specified operating temperature range from −25 °C to +105 °C for application environments requiring broad thermal tolerance.
• Environmental Compliance — RoHS compliant for regulatory conformance in applicable markets.

Typical Applications

• General‑purpose power supplies — Bulk filtering and smoothing where 400 V rated capacitance and high ripple handling are required.
• Power conversion modules — Energy storage and decoupling in converters and inverters that need reliable high‑voltage capacitors with snap‑in mounting.
• Industrial electronics — Filtering and stabilization in industrial power subsystems operating across a wide temperature range.

Unique Advantages

• High voltage capability: 400 V rating enables use in mid‑to‑high voltage designs without additional series components.
• Measured ripple performance: Specified ripple currents at both low (1.1 A at 120 Hz) and high frequency (1.573 A at 100 kHz) support predictable thermal and electrical design margins.
• Long endurance at elevated temperature: 3000 hours life at 105 °C under rated conditions delivers proven longevity for sustained operation.
• Compact snap‑in package: φ22 × 45 mm radial can with snap‑in terminals provides a secure PCB mounting option while occupying reduced board space compared to larger cans.
• Low dissipation factor: tan δ of 0.15 (20 °C, 120 Hz) helps manage losses in AC or ripple‑rich environments.
• RoHS compliance: Meets applicable environmental directives for lead‑free manufacturing requirements.
