LGY2A821MELZ30

The LGY2A821MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGY series, offering long-life assurance for industrial power applications. It delivers 820 µF at 100 V in a compact φ22 × 30 mm can, designed for robust bulk energy storage and smoothing on higher-voltage DC rails.

Targeted at industrial power supplies, ballast applications and general-purpose power filtering, this capacitor combines a high-voltage rating with a 105°C, 5000-hour endurance specification to support reliable operation in demanding environments.

Key Features

• Snap-in Terminal Package Secure snap-in can package (radial, can - snap-in) designed for reliable board mounting in mass-production assemblies; supplied in tray packing.
• Long-Life Assurance Rated for 5000 hours at 105°C under DC bias plus rated ripple current to support prolonged operation in high-temperature applications.
• High Voltage / High Capacitance 820 µF capacitance at 100 V provides substantial bulk capacitance for smoothing and energy storage on higher-voltage rails.
• Wide Operating Temperature Specified for −40°C to +105°C operation to cover typical industrial temperature ranges.
• Ripple Current Performance Rated ripple current: 1.3 A at 120 Hz and 1.495 A at 50 kHz; frequency coefficient of rated ripple current rises to 1.15 at 1 kHz and above.
• Electrical Stability and Loss Capacitance tolerance ±20% (at 120 Hz, 20°C); tan δ maximum for 100 V is 0.20 (measured at 120 Hz, 20°C).
• Leakage and Endurance Leakage current specified by I ≤ 3√CV (μA) after 5 minutes at 20°C; after endurance testing (5000 h at 105°C) capacitance change remains within ±25% and leakage current remains at or below initial specified value.
• RoHS Compliant Meets RoHS directives for environmental compliance.

Typical Applications

• Industrial Power Supplies — Bulk filtering, smoothing and energy buffering for high-voltage DC rails in industrial converters and power systems.
• Ballast Applications — Designed to withstand sustained ripple and elevated temperatures typical of ballast circuits.
• General-Purpose Power Filtering — Bulk capacitance for smoothing, hold-up and decoupling in general-purpose power and control electronics.

Unique Advantages

• Long operating life at elevated temperature — 5000-hour rating at 105°C reduces maintenance and replacement frequency in high-thermal-stress installations.
• High-voltage capability — 100 V rating enables use on higher DC rails without parallel component complexity.
• Compact high-capacitance form factor — 820 µF in a φ22 × 30 mm can saves PCB space while delivering substantial energy storage.
• Reliable ripple handling — Specified ripple currents at multiple frequencies and a defined frequency coefficient allow predictable thermal and life calculations.
• Production-friendly packaging — Tray packing supports automated assembly and inventory handling for volume production.
• Predictable electrical limits — Clear specifications for leakage current, tan δ, and endurance simplify design validation and reliability planning.
