LGJ2G101MELC15

The LGJ2G101MELC15 is a snap‑in terminal aluminum electrolytic capacitor providing 100 µF capacitance at a 400 V rating in a low‑profile φ35 × 15 mm can. It is designed for general purpose applications that require high‑voltage bulk capacitance with robust ripple handling and compact board mounting.

Key value comes from its combination of high‑voltage capability, specified ripple current performance at both low and high frequencies, and 2000‑hour endurance at 105°C, enabling reliable operation in demanding thermal environments.

Key Features

• Capacitance & Tolerance — 100 µF nominal with ±20% tolerance at 120 Hz, 20°C, providing defined bulk energy storage for DC systems.
• Voltage Rating — 400 V rated voltage to support high‑voltage DC applications within its specified range.
• Ripple Current Performance — 550 mA at 120 Hz (low frequency) and 786.5 mA at 50 kHz (high frequency) to handle both mains‑frequency and higher‑frequency ripple components.
• Thermal Endurance — Rated operating temperature range of −25°C to +105°C with a 2000‑hour life at 105°C for prolonged reliability in elevated temperature conditions.
• Leakage Current & Polarization — Polarized electrolytic design with specified leakage current of 600 µA at rated conditions.
• Package & Mounting — Radial snap‑in can (φ35 × 15 mm low profile) for secure chassis or PCB mounting and compact system integration; supplied in tray packing suitable for mass production.

Typical Applications

• General purpose circuits — Provides 100 µF of high‑voltage bulk capacitance where a 400 V rating and compact, low‑profile snap‑in package are required.
• High‑voltage DC filtering — Suited for smoothing and filtering tasks in DC systems that demand defined ripple handling at both mains and higher frequencies.
• Thermally stressed environments — Useful in assemblies operating up to 105°C where extended endurance (2000 h at 105°C) improves long‑term reliability.

Unique Advantages

• High‑voltage bulk capacitance: 100 µF at 400 V supplies substantial energy storage for high‑voltage circuits without increasing diameter.
• Dual‑frequency ripple handling: Rated ripple currents specified for both low (120 Hz) and high (50 kHz) frequencies, enabling predictable thermal and electrical performance across applications.
• Low‑profile, snap‑in packaging: φ35 × 15 mm can with snap‑in terminals simplifies mechanical retention and fits compact chassis or PCB layouts.
• 105°C endurance: 2000‑hour life at 105°C supports deployments in elevated temperature environments requiring sustained performance.
• Production‑ready supply: Tray packing and mass production availability aid repeatable assembly and inventory management.
