LGGW6221MELZ40

The LGGW6221MELZ40 is an aluminum electrolytic capacitor from Nichicon’s LGG series, featuring a snap‑in terminal configuration and a compact, ultra-smaller-sized case designed for space-constrained assemblies. It delivers 220 µF capacitance at a 420 V rating with polarized construction for general-purpose power applications.

Designed for reliability in elevated temperatures, this part is specified for operation from −25°C to 105°C and a rated endurance of 2000 hours at 105°C, making it suitable where long-term stability and ripple-handling capability are required in reduced-package footprints.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 420 V DC rating for high-voltage filtering and energy storage roles.
• Snap‑in Mounting & Package — Snap-in terminal type in a radial, can-style package (φ22 × 40L) for secure board mounting and compact assembly.
• Operating Temperature & Endurance — −25°C to 105°C operating range with a 2000-hour endurance rating at 105°C under DC bias plus rated ripple current.
• High Ripple Current Capability — Low-frequency ripple current of 950 mA at 120 Hz and high-frequency ripple current of 1.359 A at 100 kHz to support smoothing in power circuits.
• Leakage Current — Specified leakage current of 910 µA (per part data).
• Environmental Compliance — RoHS compliant.
• Production & Packaging — Mass production status with tray packing for handling and assembly.
• Polarized — Designed as a polarized electrolytic capacitor for DC applications.

Typical Applications

• General‑purpose electronic equipment — Provides bulk capacitance and DC filtering for a wide range of general-purpose designs.
• Power supply smoothing and ripple handling — Rated ripple current specs (950 mA at 120 Hz, 1.359 A at 100 kHz) make it suitable for smoothing and decoupling in power supplies.
• Equipment downsizing — Ultra-smaller-sized LGG series design and one-rank smaller case (compared to LGN) help reduce board area in compact systems.
• High-temperature operating environments — 105°C rating with 2000 h endurance supports use in applications requiring sustained elevated-temperature performance.

Unique Advantages

• Compact, space-saving form factor — One rank smaller case size in the LGG series enables denser board layouts and contributes to equipment miniaturization.
• High-voltage capability — 420 V rating allows use in higher-voltage DC link and power applications without additional series components.
• Robust ripple handling — Defined low- and high-frequency ripple current ratings provide quantifiable thermal and ripple management for designers.
• Defined high-temperature endurance — 2000 hours at 105°C under rated conditions gives a measurable reliability baseline for thermal stress planning.
• Production-ready packaging — Tray packing and mass-production status support volume assembly and predictable supply handling.
