LGU2E122MELC

The LGU2E122MELC from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, rated for 250 V and 1200 µF (±20%). It is a polarized, radial can snap‑in device designed for general‑purpose power applications that require high ripple handling and extended high‑temperature endurance.

Key value is delivered through its combination of high ripple current capability, a 105°C operating temperature range with 3000‑hour endurance, and tray packing for efficient assembly and handling in volume production.

Key Features

• Capacitance & Rated Voltage — 1200 µF nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20% for bulk energy storage and decoupling in 250 V systems.
• Snap‑In Mounting — Snap‑in terminal, radial can package provides secure board retention and fast assembly for through‑hole power assemblies.
• High Ripple Current — Low‑frequency ripple current of 2.6 A (120 Hz) and high‑frequency ripple current of 3.9 A (50 kHz) to support steady and switching power environments.
• High‑Temperature Endurance — Rated to operate from −40°C to +105°C with 3000 hours endurance at 105°C when subjected to rated ripple current, supporting long service life under elevated temperatures.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.15 (measured at 20°C, 120 Hz) and specified leakage current of 1640 µA for predictable damping and low standby current.
• Packaging & Compliance — Tray packing suited to production environments and RoHS‑compliant construction.

Typical Applications

• Power Supplies — Bulk smoothing and energy storage in 250 V DC rails where 1200 µF and strong ripple capability are required.
• Switching Converters — Filtering and ripple attenuation in high‑frequency switching applications leveraging the 3.9 A ripple current rating at 50 kHz.
• Industrial Power Electronics — General‑purpose use in industrial circuits that demand operation to 105°C and long endurance at rated ripple current.

Unique Advantages

• Designed for sustained high‑temperature operation — 3000 hours endurance at 105°C under rated ripple current supports reliability in hot operating environments.
• Dual‑frequency ripple capability — Specified ripple ratings at both 120 Hz and 50 kHz allow predictable performance across mains‑frequency and switching domains.
• Robust electrical stability — Tightly defined tan δ and leakage current figures enable predictable impedance and loss behavior in design simulations and thermal budgeting.
• Production‑friendly packaging — Tray packing facilitates handling and placement in volume assembly operations.
• RoHS compliance — Meets regulatory environmental requirements for lead‑free assembly processes.
