LGU1K122MELZ

The LGU1K122MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, offering 1.2 mF capacitance at an 80 V rating in a radial, can-style snap-in package. Designed for general-purpose power applications, it combines high capacitance density with rated ripple-current endurance and a wide operating temperature range to support robust power-filtering and energy-storage functions.

Key value propositions include long endurance under high-temperature ripple stress (3000 hours at 105 °C), RoHS compliance, and a compact φ22×30 mm form factor supplied in tray packing for production assembly.

Key Features

• Capacitance & Voltage — 1.2 mF (1,200 µF) rated at 80 V, providing bulk energy storage for smoothing and decoupling in DC power systems.
• Endurance & Ripple Capability — Specified to withstand 3000 hours of rated ripple current at 105 °C; ripple-current ratings include 1.44 A at 120 Hz and 1.656 A at 50 kHz.
• Thermal Range — Operating temperature range from −40 °C to 105 °C to support a broad range of ambient conditions.
• Leakage & Loss Characteristics — Leakage current specified at 920 µA; tangent of loss angle (tan δ) for the 80 V class is within the series’ listed limits (0.20 max at 120 Hz, 20 °C).
• Mechanical & Mounting — Radial, snap-in can package (φ22×30 mm) for secure board mounting and mechanical stability in high-vibration environments.
• Compliance & Availability — RoHS compliant and in mass production; supplied in tray packing for handling and assembly.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling where 1.2 mF at 80 V and specified ripple capability are required.
• High-temperature power circuits — Use in circuits that must sustain rated ripple current at elevated temperatures (endurance specified at 105 °C for 3000 hours).
• Energy storage / hold-up functions — Local energy reservoir for short-term load support or transient response within the capacitor’s voltage and temperature limits.

Unique Advantages

• High-capacitance density: 1.2 mF in a compact φ22×30 mm snap-in can delivers substantial bulk storage without excessive board real estate.
• Rated high-temperature endurance: Endurance validated for 3000 hours at 105 °C under rated ripple current, giving designers quantifiable long-term performance data.
• Defined ripple performance across frequencies: Ripple-current specifications at 120 Hz and 50 kHz allow designers to size filter components against real operating conditions.
• Robust mounting: Snap-in radial can package provides secure mechanical retention for production assemblies and high-vibration environments.
• Regulatory compliance: RoHS compliant construction supports environmental and regulatory requirements for modern electronics production.
• Production-ready supply: Tray packing and mass-production status simplify procurement and assembly planning.
