LGU2A821MELZ

The LGU2A821MELZ is a snap‑in aluminum electrolytic capacitor from Nichicon's LGU series, offering 820 µF capacitance at a 100 V rating in a compact φ22 × 30 mm can. It is a polarized, radial snap‑in package designed for general‑purpose electronic equipment that requires bulk capacitance and high‑voltage capability.

Built to operate over a wide temperature range (‑40 °C to 105 °C) and rated for extended endurance, this part targets applications where sustained ripple current and long life at elevated temperature are required.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 100 V DC.
• High‑temperature Endurance — Designed for operation up to 105 °C with a rated endurance of 3000 hours when subjected to rated ripple current and DC bias.
• Ripple Current Performance — Low‑frequency ripple current 1.35 A (120 Hz) and high‑frequency ripple current 1.552 A (50 kHz), supporting demanding AC load conditions within specified ratings.
• Loss and Leakage — Measured tangent of loss angle (tan δ) condition at 20 °C, 120 Hz with tan δ specified for the 100 V rating; specified leakage current of 850 µA.
• Package & Mounting — Snap‑in, radial can package (φ22 × 30 mm) provided in tray packing for easy handling and PCB insertion.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• General‑purpose electronic equipment — Bulk capacitance for power conditioning and energy storage in a variety of electronic systems where a 100 V rating is required.
• Power supply smoothing — Filtering and smoothing of DC supplies in equipment operating across the rated temperature range.
• Industrial and commercial assemblies — Snap‑in format and tray packing streamline assembly for rack or panel power electronics and other general‑purpose builds.

Unique Advantages

• Extended high‑temperature life: 3000‑hour endurance at 105 °C under rated ripple current enables predictable long‑term performance in hot environments.
• High voltage capability: 100 V rating provides headroom for higher‑voltage rails while maintaining compact φ22 × 30 mm dimensions.
• Measurable ripple handling: Published ripple current values at both 120 Hz and 50 kHz make it easier to size and validate for AC stress in designs.
• Practical assembly format: Snap‑in radial can and tray packing simplify PCB insertion and handling during production.
• Clear electrical characteristics: Specified tan δ test condition (20 °C, 120 Hz) and leakage current figure support engineering validation and acceptance testing.
