LGJ2W101MELB20

The LGJ2W101MELB20 is a Nichicon LGJ series aluminum electrolytic capacitor in a snap-in terminal, low-profile can. It delivers 100 µF capacitance at a 450 V rating with polarized construction for high-voltage DC applications.

Designed for general-purpose power circuits, this part combines high ripple handling, a compact φ30 × 20 mm footprint, and a 3,000-hour endurance at 105°C to support robust performance in industrial and high-voltage power systems.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), suitable for DC filtering and energy smoothing tasks.
• High Rated Voltage — 450 V rated voltage for use in high-voltage DC rails and power-supply sections requiring elevated voltage headroom.
• Temperature & Endurance — Rated for operation from −25°C to +105°C with a specified lifetime of 3,000 hours at 105°C, supporting sustained high-temperature environments.
• Ripple Current Capability — 830 mA at low frequency (120 Hz) and 1.187 A at high frequency (50 kHz), enabling effective AC ripple handling in switching and rectifier circuits.
• Leakage Current — Specified leakage current of 630 µA, providing predictable leakage behavior for bias and hold-up applications.
• Package & Mounting — Snap-in (radial, can snap-in) construction in a compact φ30 × 20L (φ30 mm × 20 mm) low-profile case; supplied in tray packing for mass-production assembly.
• Series & Manufacturer — Part of the Nichicon LGJ series, representing a snap-in terminal family with low-profile sizing and high-temperature endurance.

Typical Applications

• High-Voltage Power Supplies — Bulk filtering and smoothing on 450 V DC rails where compact, high-voltage capacitors are required.
• Industrial Power Electronics — DC-link and energy buffering in industrial converters and control equipment that demand elevated voltage and ripple handling.
• Switching/Rectifier Circuits — Output and intermediate filtering for rectifiers and switching supplies benefitting from the specified ripple current ratings.
• High-Temperature Environments — Applications requiring long endurance at elevated temperatures, supported by a 3,000-hour rating at 105°C.

Unique Advantages

• High-Voltage Capability: 450 V rating enables integration into high-voltage DC systems without series stacking or additional components.
• Compact Low-Profile Form: φ30 × 20 mm size and snap-in mounting deliver a space-efficient solution for chassis-mounted power designs.
• Strong Ripple Handling: Defined ripple specifications at both low and high frequencies (830 mA @120 Hz, 1.187 A @50 kHz) support robust smoothing across switching regimes.
• Extended High-Temperature Life: 3,000-hour endurance at 105°C gives predictable lifetime performance in thermally demanding installations.
• Production-Ready Packaging: Tray packing and mass-production status simplify procurement and high-volume assembly workflows.
