LGU2D221MELY

The LGU2D221MELY is a Nichicon LGU series snap‑in aluminum electrolytic capacitor designed for general‑purpose power applications. It provides 220 µF capacitance at a 200 V rating in a radial snap‑in can package, optimized for bulk energy storage, filtering and ripple suppression in industrial and power‑supply environments. The part combines a wide operating temperature range with a proven 3,000‑hour endurance at 105°C for reliable long‑term performance.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 200 V rated voltage and a tolerance of −20% to +20%.
• High‑temperature endurance — Specified life of 3,000 hours at 105°C when subjected to DC bias plus rated ripple current, supporting demanding thermal environments.
• Ripple current capability — Low‑frequency ripple current of 1,000 mA at 120 Hz and high‑frequency ripple current of 1,500 mA at 50 kHz for effective smoothing in both mains and switching supplies.
• Loss characteristics — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz (consistent with the 160–420 V category in the LGU series).
• Leakage current — Specified leakage current of 620 µA after rated voltage application at 20°C (per product specification).
• Robust temperature range — Operates from −40°C to +105°C, allowing use across a broad set of ambient conditions.
• Package & mounting — Snap‑in terminal radial can (φ20 × 25L), designed for secure board mounting and tray packing for production handling.
• RoHS compliant — Meets RoHS directives applicable to the LGU series.

Typical Applications

• Power supplies — Bulk filtering and output smoothing in switching and linear power supply stages where 200 V rating and high ripple capability are required.
• Industrial equipment — Energy storage and decoupling in motor drives, inverters, and control systems operating across wide temperature ranges.
• Electronic assemblies with high ripple loads — Filtering of high‑frequency switching noise and handling of sustained ripple currents in long‑life applications.

Unique Advantages

• Proven high‑temperature life: 3,000 hours at 105°C under rated ripple current provides predictable ageing and endurance for thermal stress applications.
• Dual‑frequency ripple support: Rated ripple currents given for both 120 Hz and 50 kHz ensure suitability across mains frequency filtering and high‑frequency switching domains.
• Compact snap‑in format: φ20 × 25L radial snap‑in can offers a space‑efficient solution for panel or PCB layouts while providing secure mechanical retention.
• Series‑level reliability data: LGU series specifications (category temperature range, rated voltage and capacitance ranges, and frequency coefficients) back expected performance across applications.
• Compliance and handling: RoHS compliant and supplied in tray packing to support production throughput and traceability.
