LGU2D821MELA

The LGU2D821MELA is a Nichicon LGU series snap-in aluminum electrolytic capacitor specified for 200 V applications with 820 µF nominal capacitance. It combines a snap-in radial can package with high-temperature endurance and defined ripple-current capability for general-purpose equipment.

Designed for environments that require sustained performance at elevated temperatures, this part offers a 105°C rated operating range and a 3000-hour endurance under rated ripple conditions, making it suitable for production deployments where reliability and repeatable electrical characteristics matter.

Key Features

• Form factor & mounting — Snap-in terminal radial can with dimensions φ25 × 45 mm (L: 4.5 × D: 2.5 cm); packaged in trays for production handling.
• Capacitance & tolerance — 820 µF nominal capacitance with tolerance −20% to +20% (±20% at 120 Hz, 20°C).
• Voltage rating — Rated for 200 V DC operation.
• Thermal rating & endurance — Operating temperature range −40°C to +105°C and rated for 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple current capability — Low-frequency ripple current 2.04 A at 120 Hz and high-frequency ripple current 3.06 A at 50 kHz (specified values).
• Leakage and dissipation — Specified leakage current 1210 µA (after 5 minutes at 20°C) and tanδ (loss tangent) 0.15 measured at 120 Hz, 20°C.
• Compliance & production status — RoHS compliant and available in mass production.

Typical Applications

• General-purpose power supplies — For designers requiring a 200 V, 820 µF snap-in capacitor with defined ripple-current and high-temperature endurance for smoothing and bulk storage in general-purpose equipment.
• Industrial and commercial equipment — Applicable where a robust, tray-packed radial can capacitor with a −40°C to +105°C operating range and 3000 h endurance is needed.
• Production-volume assemblies — Tray packing and mass-production availability support repeatable procurement and placement of snap-in capacitors in high-volume builds.

Unique Advantages

• High-temperature endurance: Rated for 3000 hours at 105°C under rated ripple current, supporting long-term operation in elevated-temperature environments.
• Defined ripple performance: Published ripple current specifications at 120 Hz (2.04 A) and 50 kHz (3.06 A) make thermal and EMC planning more predictable.
• Compact snap-in package: φ25 × 45 mm radial can with snap-in terminals provides a secure PCB mounting option for high-current smoothing applications.
• Measured electrical characteristics: Specified leakage current (1210 µA) and tanδ (0.15 at 120 Hz, 20°C) enable accurate margining in designs.
• RoHS compliant & production ready: Environmentally compliant material set and mass-production status simplify supply-chain integration.
