LGC2H221MELB30

The LGC2H221MELB30 is a Nichicon LGC series snap‑in terminal aluminum electrolytic capacitor engineered for long life in compact assemblies. It provides 220 µF of capacitance at a 500 V rating in a radial, snap‑in can designed to support equipment downsizing by using a one‑rank smaller case than the LGX series.

Designed for general‑purpose high‑voltage DC applications, the part supports operation from –40°C to +105°C with a specified long‑life endurance of 5000 hours at 105°C and is RoHS compliant.

Key Features

• Electrical Capacity — 220 µF rated capacitance at 500 V with ±20% tolerance (120 Hz, 20°C), providing high bulk energy storage for high‑voltage circuits.
• Long Life and Temperature Range — Endurance specified at 5000 hours at 105°C; operating temperature range –40°C to +105°C for robust thermal performance.
• Mounting and Package — Radial, can type with snap‑in terminals for secure board mounting and automated assembly compatibility.
• Ripple Current Capability — Rated ripple current of 1.29 A at 120 Hz and 1.845 A at 50 kHz (part specific), supporting AC ripple handling in power conversion and filtering circuits.
• Leakage and Loss Characteristics — Leakage current met by I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ ≤ 0.25 (120 Hz, 20°C) for predictable loss behavior.
• Size — Compact 30 × 30 mm package footprint (L: 3 × D: 3 cm) that helps reduce PCB area in space‑constrained designs.
• Compliance — RoHS directive compliant.

Typical Applications

• High‑voltage power supplies — Bulk DC filtering and energy storage where 500 V rating and 220 µF capacitance stabilize voltage rails.
• Power conversion and inverters — Smoothing and ripple handling in AC‑to‑DC or DC‑to‑DC stages, leveraging the part’s rated ripple current and long‑life endurance.
• Industrial equipment — General‑purpose high‑voltage filtering in industrial control systems requiring robust thermal endurance.

Unique Advantages

• Compact high‑voltage solution: 220 µF at 500 V in a 30 × 30 mm can delivers substantial bulk capacitance while enabling equipment downsizing compared with the LGX series.
• Long operational life: 5000 hours at 105°C endurance specification supports extended service life in thermally demanding environments.
• Reliable board retention: Snap‑in terminals provide mechanical stability and suitability for automated PCB assembly.
• Predictable electrical behavior: Clear leakage current formula (I ≤ 3√CV) and tan δ limit (≤ 0.25) enable designers to model loss and leakage for system‑level calculations.
• Wide temperature range: –40°C to +105°C operation covers common industrial and commercial operating environments.
• Regulatory compliance: RoHS conformity reduces environmental/REACH compliance overhead in product builds.
