LGL2G221MELZ30

The LGL2G221MELZ30 is a Nichicon aluminum electrolytic capacitor in a snap‑in terminal radial can designed for general-purpose power applications. It delivers 220 µF at a 400 V rated voltage in a compact 22 × 30 mm package with polarized termination and tray packing for production handling.

Engineered for high-voltage smoothing and ripple handling, this part offers a wide operating temperature range (−25°C to 105°C), 2000-hour endurance at 105°C, and specified ripple and leakage characteristics to support reliable operation in sustained DC bias environments.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 400 V for high-voltage bulk energy storage and filtering.
• Compact Snap‑in Package — Radial snap‑in can, 22 mm diameter × 30 mm length, designed for secure PCB mounting and automated assembly with tray packing for mass production.
• Temperature & Endurance — Rated for −25°C to +105°C with a 2000-hour life specification at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — 780 mA at 120 Hz (low frequency) and 1.115 A at 50 kHz (high frequency) ripple current capability to handle sustained AC components on DC lines.
• Leakage & Loss Angle — Leakage current specified at 880 µA and tan δ (DF) max 0.15 measured at 20°C and 120 Hz, providing predictable loss and leakage behavior.
• Tolerance & Polarization — Capacitance tolerance of ±20% (at 120 Hz, 20°C); polarized device suitable where correct polarity is observed.
• Production-Ready Packaging — Tray packing and mass production status simplify supply-chain handling and assembly planning.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in high-voltage DC power supplies where 400 V rating and 220 µF capacitance are required.
• Switching power supplies — Energy storage and ripple absorption in power stages that require high-voltage capacitance and defined ripple current ratings.
• Industrial power electronics — Use in general-purpose industrial circuits that operate across −25°C to +105°C and demand 2000-hour endurance at elevated temperature.
• High-voltage DC link circuits — Support for DC link smoothing where polarized high-voltage aluminum electrolytics are appropriate and full polarity awareness is ensured.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage power circuits without parallel capacitor arrangements.
• Compact footprint: 22 × 30 mm snap‑in can provides 220 µF capacitance in a space-efficient radial package for denser board layouts.
• Defined high‑frequency performance: Specified ripple current at both 120 Hz and 50 kHz (780 mA and 1.115 A respectively) gives designers quantifiable margins for AC stress.
• Long endurance at elevated temperature: 2000 hours at 105°C under rated conditions supports designs with sustained thermal and electrical stress.
• Predictable leakage and loss: Leakage current of 880 µA and tan δ ≤ 0.15 (120 Hz, 20°C) enable accurate loss budgeting and thermal planning.
