LGN2H221MELB45

The LGN2H221MELB45 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic applications. It delivers 220 µF capacitance at a 500 V rating in a smaller-sized snap-in can, offering a compact, high-voltage solution.

Engineered for elevated operating conditions, this capacitor withstands rated ripple current for 3000 hours at 105°C and is specified for operation from –25°C to 105°C, making it suitable where high-temperature ripple endurance and RoHS compliance are required.

Key Features

• Electrical — 220 µF capacitance with a 500 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Thermal and Endurance — Specified operating temperature range of –25°C to 105°C and endurance of 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current figures: 1.02 A at 120 Hz and 1.459 A at 100 kHz, supporting both low- and high-frequency ripple conditions.
• Package & Mounting — Snap-in terminal type in a radial can (snap-in) package; compact physical size (L: 4.5 × D: 3 cm).
• Reliability & Compliance — Meets RoHS directive (2011/65/EU, (EU)2015/863) and is built to the LGN series specifications for stable performance over life and shelf storage.

Typical Applications

• General-purpose power systems — Use where a 500 V, 220 µF snap-in capacitor with high-temperature ripple endurance is required.
• High-temperature ripple environments — Suitable for designs that require sustained rated ripple current at up to 105°C for extended periods.
• Space-constrained assemblies — The LGN series offers a one-rank smaller case size than LGU, providing a more compact high-voltage capacitor option.

Unique Advantages

• Extended ripple endurance: Withstands rated ripple current for 3000 hours at 105°C, supporting prolonged high-temperature operation.
• High-voltage capability: 500 V rating enables application in higher-voltage circuits without series stacking.
• Compact high-voltage form factor: One rank smaller case size than LGU and a 4.5 × 3 cm footprint reduce board space for high-voltage filtering needs.
• Dual-frequency ripple handling: Specified ripple current at both 120 Hz and 100 kHz helps address a range of ripple sources.
• Regulatory compliance: RoHS-compliant construction for environmentally regulated designs.
