LGG2W221MELZ45

The LGG2W221MELZ45 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGG series, offering 220 µF capacitance at a 450 V rating. It is designed for general-purpose applications that require high-voltage capacitance in a compact, snap-in can package.

Part of the LGG family, this component is specified for a -25°C to 105°C operating range and 2000 hours endurance at 105°C, making it suitable for designs where long-term high-temperature stability and reliable ripple handling are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, providing a specified high-voltage energy-storage element in a single component.
• High-temperature Endurance — Rated for 2000 hours at 105°C with the specified DC bias plus rated ripple current; capacitance change and leakage meet the LGG series endurance criteria after testing.
• Operating Temperature Range — Specified for -25°C to 105°C operation, supporting a wide range of ambient conditions for general-purpose equipment.
• Ripple Current Performance — Rated ripple handling of 870 mA at 120 Hz and 1.244 A at 100 kHz, enabling effective smoothing and filtering under AC ripple conditions.
• Compact Snap-in Package — Radial, can-style snap-in mounting (φ22 × 45 mm / L: 4.5 × D: 2.2 cm) for secure board attachment and suitability for tray-packed, mass-production assembly.
• Polarized Electrolytic — Polar capacitor construction with leakage current specified by I ≤ 3√CV (μA) after voltage application, per LGG series characteristics.
• RoHS Compliant — Meets RoHS requirements as listed for the LGG series.

Typical Applications

• General-purpose power assemblies — Provides high-voltage capacitance for energy storage and smoothing in general-purpose equipment where a 450 V rating is required.
• Equipment downsizing — LGG series is specified as one rank smaller than LGN, making this part suited for designs targeting reduced component footprint and denser assemblies.
• High-temperature environments — Endurance at 105°C (2000 hours) supports use in assemblies exposed to elevated operating temperatures.
• Mass-production assemblies — Tray packing and snap-in mounting simplify installation for high-volume manufacturing.

Unique Advantages

• Single-component high-voltage solution: 450 V rating and 220 µF capacitance provide required high-voltage storage without series stacking of lower-voltage capacitors.
• Compact, snap-in form factor: φ22 × 45 mm can and snap-in terminals deliver a space-conscious package that supports secure mechanical mounting.
• Engineered for endurance: 2000 hours at 105°C under rated conditions demonstrates long-term stability for demanding thermal environments.
• Defined ripple capability: Explicit ripple current ratings at 120 Hz and 100 kHz allow designers to size the capacitor with known AC performance limits.
• RoHS compliance: Conforms to RoHS requirements, aligning with regulatory needs for lead-free assembly.
• Series-level design consistency: Benefits from LGG series specifications such as impedance behavior at low temperature and standard leakage current limits, aiding predictable system performance.
