LLG2W221MELA35

The LLG2W221MELA35 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It provides 220 µF of capacitance at a 450 V rating with a polarized design suited for general-purpose power applications.

Designed for equipment downsizing, the LLG series offers a smaller case footprint than the LLS line while delivering high ripple capability and RoHS compliance for production environments.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance at a 450 V rated voltage.
• Snap-in Terminal / Radial Can — Snap-in mounting style and radial can package for secure PCB installation and mass-production assembly (tray packing).
• High Ripple Current — Rated ripple current of 1.5 A at 120 Hz (low frequency) and 2.145 A at 100 kHz (high frequency), supporting demanding ripple environments.
• Low Leakage — Initial leakage current specified at 940 µA.
• Endurance & Temperature Range — 2000 hours rated life at 85°C; operating temperature range from −25°C to +85°C.
• Compact Dimensions — φ25 × 35 mm (L: 3.5 × D: 2.5 cm) package; LLG series is one rank smaller than LLS for space-constrained designs.
• Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance and smoothing in electronic systems where a 450 V, 220 µF polarized capacitor is required.
• Power conversion modules — Energy storage and ripple handling in power supply and converter circuits that demand high ripple current capability.
• Space-constrained equipment — Compact LLG series case size for designs targeting reduced board space and equipment downsizing.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power circuits without series stacking.
• Superior ripple performance: Dual-specified ripple ratings (1.5 A at 120 Hz and 2.145 A at 100 kHz) address both low- and high-frequency ripple environments.
• Compact, production-ready package: Snap-in radial can with tray packing supports high-volume assembly and secure PCB mounting.
• Durable under elevated temperature: 2000-hour endurance at 85°C for sustained performance in warmer operating conditions.
• Low initial leakage: 940 µA initial leakage current contributes to predictable performance after voltage application.
• Regulatory readiness: RoHS compliance suitable for regulated product builds.
