LGU1J472MELB

The LGU1J472MELB is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGU series, rated 63 V with a nominal capacitance of 4700 µF (4.7 mF) and ±20% tolerance. It is designed for general‑purpose power applications that require high bulk capacitance, substantial ripple handling and reliable performance in elevated temperatures.

This part delivers low loss (tan δ = 0.25 at 20°C, 120 Hz), high ripple current capability (2.9 A at 120 Hz and 3.335 A at 50 kHz), and a 3000‑hour endurance at 105°C. The device is supplied in a radial, snap‑in can (φ30 × 40 L) and is available in tray packing for mass production deployment.

Key Features

• Electrical Capacity — 4700 µF nominal capacitance (4.7 mF) with ±20% tolerance, providing substantial bulk energy storage for smoothing and decoupling in general‑purpose circuits.
• Rated Voltage — 63 V rated voltage suitable for medium‑voltage power rails and systems requiring higher DC voltage endurance.
• Low Loss Characteristic — Tangent of loss angle (tan δ) of 0.25 measured at 20°C and 120 Hz, supporting efficient performance under AC test conditions.
• High Ripple Current Capability — Rated ripple current of 2.9 A at 120 Hz (low frequency) and 3.335 A at 50 kHz (high frequency), enabling robust handling of both low‑ and high‑frequency ripple loads.
• Leakage Current — Specified leakage current of 1630 µA after 5 minutes’ application of rated voltage at 20°C, for predictable standby losses.
• Endurance and Reliability — Qualified for 3000 hours of operation at 105°C with rated ripple current applied, meeting the LGU series endurance specification for high‑temperature use.
• Operating Temperature Range — −40°C to +105°C, accommodating a wide range of environmental conditions.
• Package & Mounting — Radial, snap‑in can (φ30 × 40 L) with snap‑in terminals for secure board retention and straightforward assembly; supplied in tray packing for production lines.
• Regulatory Status — Compliant with RoHS (2011/65/EU, (EU)2015/863) as part of the LGU series.

Typical Applications

• General‑purpose power systems — Bulk smoothing and energy storage where high capacitance and elevated ripple current capability help stabilize DC rails.
• Industrial electronics — Filtering and decoupling in equipment that operates across −40°C to +105°C and requires long endurance at elevated temperatures.
• Power supply modules — Input/output filtering on medium‑voltage supplies that benefit from 63 V rating and high ripple handling.

Unique Advantages

• High ripple tolerance: 2.9 A (120 Hz) and 3.335 A (50 kHz) ratings reduce temperature rise under ripple loading and extend service life in demanding AC conditions.
• Long high‑temperature endurance: 3000 hours at 105°C with rated ripple current applied offers predictable lifecycle performance in hot environments.
• Substantial bulk capacitance: 4700 µF provides significant energy reserve for smoothing and transient support in general‑purpose power designs.
• Snap‑in radial package: φ30 × 40 L can with snap‑in terminals enables secure PCB retention and efficient assembly using tray packing for mass production.
• Measured loss performance: Specified tan δ = 0.25 at 20°C/120 Hz supports design calculations for dissipation and impedance under AC conditions.
• RoHS compliant: Meets RoHS directive requirements for environmentally restricted substances.
