LGN2P821MELZ50

The LGN2P821MELZ50 is a snap‑in, large‑can aluminum electrolytic capacitor from Nichicon's LGN series. It provides 820 µF capacitance at a 220 V rating in a compact φ22 × 50 mm can designed for snap‑in mounting.

Engineered for general‑purpose power applications, this part delivers high ripple current capability and extended life at elevated temperature, making it suitable where bulk capacitance, ripple endurance, and long operating life are required.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a rated voltage of 220 V and a tolerance of −20% to +20% for predictable bulk energy storage.
• High Ripple Current Handling — Low‑frequency ripple current of 1.93 A (120 Hz) and high‑frequency ripple current of 2.895 A (100 kHz) to support demanding AC ripple environments.
• Endurance at Elevated Temperature — Rated for 3000 hours of operation at 105°C under rated ripple conditions, supporting sustained high‑temperature use.
• Wide Operating Range — Specified operating temperature range of −40°C to 105°C for use across a broad set of ambient conditions.
• Low Dissipation Factor — Tan δ (DF) specified at a maximum of 0.15 (measured at 20°C, 120 Hz), indicating controlled losses for power applications.
• Leakage Current — Specified leakage current of 1270 µA (measured after standard conditions), useful for system leakage budgeting.
• Snap‑In, Radial Can Package — φ22 × 50 mm radial can with snap‑in terminals for robust board retention and ease of vertical mounting; supplied in tray packing for handling.
• Compliance — RoHS compliant.

Typical Applications

• General‑Purpose Power Supplies — Bulk capacitance and rated ripple current make this capacitor suitable for smoothing and energy storage in general‑purpose power circuits.
• Industrial Power Modules — Long endurance at 105°C supports continuous operation in industrial power conversion and conditioning equipment.
• High‑Ripple Environments — Designed to withstand extended application of rated ripple current, appropriate for circuits with significant AC ripple content.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 1.93 A (120 Hz) and 2.895 A (100 kHz) enable reliable performance under both low‑ and high‑frequency ripple loading.
• Long high‑temperature life: Rated for 3000 hours at 105°C under rated conditions for extended service life in elevated temperature environments.
• Compact snap‑in package: φ22 × 50 mm large‑can design with snap‑in terminals provides a one‑rank smaller case size within the series while maintaining required capacitance.
• Predictable electrical characteristics: Low tan δ (max. 0.15 at 20°C, 120 Hz) and defined leakage current support accurate system design and thermal budgeting.
• Wide temperature operation: −40°C to 105°C rating supports deployment across varied ambient conditions without sacrificing performance.
• RoHS compliant and mass production availability: Manufactured by Nichicon and supplied in tray packing for production use.
