LGU1J103MELC

The LGU1J103MELC is a snap-in aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers 10,000 µF nominal capacitance with a 63 V rating in a radial snap‑in can (φ35 × 50 mm).

Designed for general-purpose applications, this part combines high bulk capacitance, elevated ripple-current capability, and a wide operating temperature range (−40°C to 105°C) with a 3000-hour endurance at 105°C.

Key Features

• Capacitance & Tolerance — 10,000 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Voltage Rating — Rated at 63 V for medium-voltage general-purpose designs.
• High Temperature Endurance — Specified life of 3000 hours at 105°C under rated ripple conditions.
• Wide Operating Range — Operating temperature from −40°C to 105°C for varied thermal environments.
• Ripple Current Capability — Low-frequency ripple current of 4.69 A (120 Hz) and high-frequency ripple current of 5.394 A (50 kHz), supporting demanding ripple conditions.
• Electrical Loss & Leakage — tanδ (DF) of 0.25 measured at 20°C, 120 Hz, and leakage current specified as 2380 µA.
• Package & Mounting — Radial snap‑in can (φ35 × 50 mm) with tray packing for board-level snap-in mounting.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose systems — Bulk capacitance for equipment and assemblies specified as general purpose.
• High-temperature environments — Use where operation up to 105°C and 3000-hour endurance at 105°C are required.
• High ripple-current circuits — Suitable where significant AC ripple handling is needed, supported by the listed ripple-current ratings.

Unique Advantages

• Substantial energy storage: 10,000 µF provides significant bulk capacitance for smoothing and decoupling roles in applicable designs.
• Robust thermal performance: Rated for −40°C to 105°C with a validated 3000‑hour life at 105°C to support long-term high-temperature operation.
• High ripple tolerance: Defined ripple-current ratings at both low and high frequencies reduce thermal stress during AC loading.
• Board-ready snap-in form factor: Radial snap‑in can (φ35×50 mm) enables secure mechanical mounting and straightforward assembly using tray packing.
• Measured electrical characteristics: Specified tanδ and leakage current values provide clear expectations for loss and standby current in designs.
• RoHS compliant: Aligns with environmental directive requirements for restricted substances.
