LGU2C102MELZ

The LGU2C102MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It provides 1000 µF capacitance at a 160 V rating in a radial, can-style snap‑in package designed for general purpose power applications.

Key value propositions include high ripple‑current capability (2.25 A at 120 Hz, 3.375 A at 100 kHz), long endurance (3000 hours at 105°C), low leakage, and a wide operating temperature range (–40°C to +105°C), making it suitable for demanding industrial and power‑electronics environments.

Key Features

• Capacitance & Tolerance — 1000 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and filtering.
• Rated Voltage — 160 V DC rating for mid‑voltage DC bus and power supply applications.
• Ripple Current Performance — 2.25 A at 120 Hz and 3.375 A at 100 kHz to support both low‑ and high‑frequency filtering demands.
• Low Leakage — Rated leakage current of 1.2 µA, enabling stable performance in DC circuits.
• High Temperature Endurance — Designed for 3000 hours at 105°C under rated ripple current, providing durability in thermal stress conditions.
• Operating Temperature Range — –40°C to +105°C for broad environmental compatibility.
• Package & Mounting — Radial, can snap‑in construction (φ22×50L; 22 mm diameter × 50 mm length / 5 × 2.2 cm) for secure mechanical mounting in power assemblies.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• Power supply filtering — Bulk and smoothing capacitor for industrial and commercial DC power supplies where 160 V and high ripple tolerance are required.
• DC bus / DC link — Energy storage and ripple suppression for mid‑voltage converter and inverter DC links using the part’s rated voltage and ripple current capability.
• Industrial power electronics — Support for motor drives, UPS subsystems, and other general purpose power electronics that demand high temperature endurance and reliable ripple handling.

Unique Advantages

• High ripple‑current endurance: 2.25 A (120 Hz) and 3.375 A (100 kHz) ratings reduce heating and extend operational stability under AC stress.
• Long life at elevated temperature: 3000 hours at 105°C under rated ripple current provides a quantifiable endurance metric for design lifetime planning.
• Low leakage current: 1.2 µA leakage supports stable DC performance and minimizes self‑discharge for sensitive circuits.
• Robust snap‑in mounting: Radial snap‑in can (φ22×50L) delivers sturdy mechanical retention for rack or chassis installations.
• Wide operating range: –40°C to +105°C operation covers a broad set of industrial environments without additional derating for temperature extremes.
• Regulatory compliance: RoHS‑compliant construction aligns with common environmental requirements.
