LGJ2G151MELB20

The LGJ2G151MELB20 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGJ series, provided in a low-profile large-can package. It delivers 150 µF at a 400 V rating and is intended for general-purpose power applications requiring high-voltage bulk capacitance in a compact footprint.

Key strengths include high ripple handling across low and high frequencies, a wide operating temperature range up to 105°C, and a specified endurance of 3000 hours at 105°C—making it suitable for designs that demand sustained performance in elevated temperature environments.

Key Features

• Capacitance and Tolerance — 150 µF nominal with tolerance of −20% to +20%, suitable for bulk energy storage and smoothing applications.
• Rated Voltage — 400 V DC rating for high-voltage power rail use.
• Electrical Loss (tan δ) — tanδ up to 0.15 measured at 20°C and 120 Hz, enabling predictable dissipation characteristics in AC ripple conditions.
• Leakage Current — Specified leakage current of 730 µA (post-conditioning measurement basis provided), helping set expectations for bias current in designs.
• Ripple Current Capability — 900 mA at 120 Hz (low-frequency) and 1.287 A at 50 kHz (high-frequency), supporting both mains-frequency smoothing and higher-frequency switching environments.
• Temperature and Endurance — Operating range of −25°C to +105°C with an endurance rating of 3000 hours at 105°C for long-term high-temperature service.
• Package and Mounting — Radial, can-type snap-in package in a compact φ30 × 20 mm footprint, supplied in tray packing and available in mass production quantities.

Typical Applications

• Power Supply Filtering — Bulk smoothing and energy storage on high-voltage DC rails where 400 V working voltage and 150 µF capacitance are required.
• Industrial Power Conversion — DC bus decoupling and ripple attenuation in industrial converters and power modules operating at elevated temperatures.
• AC/DC and DC/DC Converters — Support for both low-frequency mains ripple handling and higher-frequency switching ripple thanks to specified ripple current performance at 120 Hz and 50 kHz.

Unique Advantages

• High-Voltage Capability: 400 V rating enables use on higher-voltage DC rails without the need for series stacking.
• Balanced Ripple Performance: Defined ripple current values at both 120 Hz and 50 kHz let designers size capacitors for mixed-frequency environments.
• Compact Low-Profile Can: φ30 × 20 mm package provides substantial capacitance in a space-efficient form factor for constrained enclosures.
• Extended High-Temperature Endurance: 3000 hours at 105°C supports product lifecycles in environments where elevated temperatures are expected.
• Manufacturing-Ready Packaging: Tray packing and mass-production status simplify procurement and assembly planning.
