LGU2P122MELC

The LGU2P122MELC from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGU series, rated 220 V with 1200 µF nominal capacitance. It is designed for general-purpose power applications that require high ripple handling and extended endurance at elevated temperatures.

Key value propositions include a high-rated voltage and capacitance combination, robust ripple-current capability at both low and high frequencies, and a guaranteed 3000 hours endurance at 105°C under rated ripple current conditions, supporting reliable operation in demanding industrial and commercial power systems.

Key Features

• Electrical Performance — 1.2 mF (1200 µF) capacitance with ±20% tolerance and polarized construction for DC filtering and energy storage in power circuits.
• High Voltage Rating — Rated voltage 220 V, suitable for higher-voltage DC bus and power-supply applications.
• Ripple Current Capability — Low-frequency ripple current 2.6 A at 120 Hz and high-frequency ripple current 3.9 A at 50 kHz, enabling effective smoothing under varying switching frequencies.
• Endurance at Elevated Temperature — Rated for 3000 hours at 105°C with rated ripple current applied; capacitors meet specified limits for capacitance change, tan δ, and leakage after the endurance test.
• Low Loss Characteristic — tan δ (loss tangent) 0.15 measured at 20°C, 120 Hz (applicable to this voltage range), indicating controlled dissipation for stable operation.
• Temperature Range — Operates from −40°C to +105°C to cover a wide range of environmental conditions.
• Package & Mounting — Snap‑in radial can (φ35 × 40L) for secure PCB mounting and tray packing for production handling; mass production status.
• Regulatory — RoHS compliant.

Typical Applications

• AC/DC and DC/DC Power Supplies — Bulk filtering and output smoothing on 220 V-class rails where high capacitance and ripple handling are required.
• Industrial Control Equipment — Energy storage and decoupling in drives and control systems that operate across −40°C to +105°C.
• Power Conversion and Motor Drives — DC bus smoothing and ripple suppression in converters with significant switching ripple at both low and high frequencies.
• Commercial UPS and Power Backup — Supporting sustained ripple currents and long endurance at elevated temperatures for reliable backup power performance.

Unique Advantages

• High Voltage and High Capacitance Combination: 220 V rating with 1200 µF provides substantial stored energy in a compact snap‑in can for higher-voltage power rails.
• Dual-Frequency Ripple Performance: Specified ripple current at 120 Hz and at 50 kHz (2.6 A and 3.9 A respectively) addresses both line-frequency and high-frequency switching environments.
• Long Endurance at 105°C: 3000 hours endurance under rated ripple current supports longevity in hot operating environments and reduces maintenance cycles.
• Controlled Dissipation: tan δ 0.15 (20°C, 120 Hz) gives predictable loss characteristics for thermal and efficiency planning.
• Tray Packing for Production: Tray packing supports automated assembly and handling in volume manufacturing.
• RoHS Compliant: Meets environmental regulatory requirements for lead-free assembly.
