LGW2G151MELZ35

The LGW2G151MELZ35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGW series. It delivers 150 µF capacitance at a 400 V rating in a compact 22 mm × 35 mm can-style package, designed for general-purpose high-voltage applications that require elevated ripple handling and long-term thermal endurance.

Engineered for demanding power environments, this polarized capacitor combines high ripple-current capability and extended life at 105°C to support filtering and energy-storage needs in high-voltage power systems.

Key Features

• High voltage and capacitance — Rated for 400 V with 150 µF capacitance, providing bulk energy storage for high-voltage circuits.
• High ripple-current capability — Rated ripple current of 1.33 A at 120 Hz and 1.902 A at 50 kHz, enabling effective smoothing under AC ripple conditions.
• 105°C endurance — Withstands application of rated ripple current for 3000 hours at 105°C, supporting long-term reliability in elevated-temperature environments.
• Robust package and mounting — Snap-in radial can (22 mm diameter × 35 mm length) for secure board mounting and straightforward installation.
• Operating temperature range — Specified for −25°C to +105°C to cover a wide set of industrial and power applications.
• Polarized with standard tolerance — Polarized capacitor with ±20% capacitance tolerance (−20% to +20%).
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-voltage power supplies — Bulk filtering and smoothing where a 400 V rated capacitor with strong ripple-handling is required.
• Industrial power equipment — Energy storage and ripple mitigation in general-purpose industrial power circuits operating up to 105°C.
• Power conversion and inverters — Support for DC link and filtering duties where snap-in mounting and high ripple endurance are advantageous.

Unique Advantages

• Long ripple endurance: Designed to withstand 3000 hours of rated ripple current at 105°C, reducing maintenance and replacement frequency.
• Measurable ripple performance: Specified ripple current values at 120 Hz (1.33 A) and 50 kHz (1.902 A) let designers size capacitors against actual ripple conditions.
• Compact, serviceable form factor: 22 mm × 35 mm snap-in can provides a small footprint with robust board retention.
• Wide thermal margin: Operation from −25°C to +105°C supports higher-temperature installations without sacrificing performance.
• Regulatory compliance: RoHS compliance supports environmentally conscious designs and regulatory requirements.
