LGG2W121MELZ30

The LGG2W121MELZ30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGG series. It delivers 120 µF capacitance at a 450 V rating in an ultra‑small snap‑in can intended for general‑purpose applications.

Designed for equipment downsizing and reliable operation in elevated temperatures, this device combines compact dimensions with high voltage capability and specified ripple handling for use in a variety of industrial and electronic assemblies.

Key Features

• Capacitance and Tolerance — 120 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated voltage of 450 V for high‑voltage circuit applications.
• Snap‑In Radial Package — Snap‑in terminal, radial can package (φ22 × 30 mm), suited to PCB mounting and secure mechanical retention.
• Ripple Current Capability — Specified ripple current of 690 mA at 120 Hz (low frequency) and 986.7 mA at 100 kHz (high frequency), supporting AC ripple handling requirements.
• Low Leakage and Endurance — Leakage current of 690 µA and 2000 hours endurance at 105°C under rated conditions.
• Wide Operating Temperature — Operating range from −25°C to +105°C to accommodate elevated temperature environments.
• Compact, Ultra‑Smaller‑Sized — LGG series provides one rank smaller case size compared with predecessor models, aiding equipment downsizing.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General‑purpose power assemblies — Provides bulk capacitance and high voltage rating for general-purpose electronic equipment.
• Space‑constrained designs — Compact φ22 × 30 mm snap‑in package helps reduce overall equipment footprint where downsizing is required.
• High‑voltage PCB modules — Snap‑in mounting and 450 V rating suit integration into high‑voltage assemblies requiring robust mechanical mounting.

Unique Advantages

• High‑voltage compatibility: 450 V rating enables use in higher DC bus and power applications without added series stacking.
• Compact snap‑in form factor: φ22 × 30 mm package and snap‑in terminals offer a smaller case size for space‑sensitive builds and secure PCB mounting.
• Specified ripple performance: Clear low‑ and high‑frequency ripple current ratings (690 mA @120 Hz, 986.7 mA @100 kHz) provide predictable thermal and lifetime behavior under ripple loading.
• High‑temperature endurance: Rated for 2000 hours at 105°C, supporting sustained operation in elevated temperature environments.
• Controlled leakage: Low leakage current (690 µA) helps maintain circuit stability and reduces standby losses.
• Regulatory compliance: RoHS compliance supports deployment in regions requiring restricted substances conformance.
