LGGW6221MELA35

The LGGW6221MELA35 is a snap-in, large-can aluminum electrolytic capacitor from Nichicon's LGG series designed for general-purpose high-voltage applications. It delivers 220 µF nominal capacitance at a 420 V rating in a compact φ25 × 35 mm can with snap-in terminals for secure board-level mounting.

Engineered for durability and board integration, this capacitor combines a wide operating temperature range (–25°C to +105°C), a 2000-hour endurance at 105°C, and measurable ripple performance at both low and high frequencies to support robust power designs.

Key Features

• Snap-In Large-Can Package Radial, can-type snap-in construction with dimensions φ25 × 35 mm (L: 3.5 × D: 2.5 cm) for compact board-level high-voltage implementations.
• High Voltage Rating Rated for 420 V DC, suitable for circuits that require elevated DC voltage handling.
• Capacitance and Tolerance 220 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Ripple Current Performance Supports 1.05 A ripple at 120 Hz and approximately 1.50 A at 100 kHz, enabling effective smoothing under both low- and high-frequency ripple conditions.
• Loss and Leakage Characteristics Tangent of loss angle (tan δ) max 0.15 (measured at 120 Hz, 20°C) and specified leakage current of 910 µA after standard test conditions.
• Endurance and Temperature Rated for 2000 hours at 105°C and operable over –25°C to +105°C, consistent with 400–450 V product category limits in the LGG series.
• RoHS Compliant and Tray Packed Material compliance with RoHS directive and supplied in tray packing for efficient handling in production environments.

Typical Applications

• General-Purpose Power Systems Bulk capacitance and high-voltage rating make this capacitor suitable for general-purpose power electronics requiring stable DC bus support.
• Board-Level High-Voltage Modules Snap-in terminals and the φ25 × 35 mm can form factor allow secure mounting and compact placement in board-level power modules.
• High-Temperature Environments Endurance of 2000 hours at 105°C and an operating range to +105°C support continued operation in thermally demanding assemblies.

Unique Advantages

• Compact, Down-Sized Can Design: Part of the LGG series, which offers one rank smaller case sizing compared to LGN, enabling equipment downsizing while maintaining required capacitance.
• High DC Voltage Capability: 420 V rating lets designers implement higher-voltage DC bus and filtering functions without stacking multiple capacitors.
• Measured Ripple Performance at Multiple Frequencies: Specified ripple current at 120 Hz and 100 kHz provides verifiable performance data for both mains-frequency and high-frequency applications.
• Robust Endurance: 2000 hours at 105°C specified endurance supports long-term reliability in elevated-temperature use cases.
• Controlled Loss and Leakage: Low tan δ (max 0.15 at 120 Hz) and defined leakage current support predictable thermal and power-loss budgeting in designs.
• Manufacturing-Friendly Packaging: Tray packing and snap-in terminals assist automated handling and reliable PCB retention during assembly.
