LGU1J272MELZ

The LGU1J272MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, designed for general-purpose power applications. It provides 2.7 mF (2700 µF) capacitance at a 63 V rating in a compact φ22 × 40 mm can with snap-in mounting, delivering high ripple-handling capability and extended endurance for demanding industrial environments.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance at a rated voltage of 63 V with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Low Loss — Tangent of loss angle (tan δ) of 0.25 measured at 20°C and 120 Hz for stable loss characteristics under typical operating conditions.
• High Ripple Current Endurance — Rated low-frequency ripple current of 2.07 A at 120 Hz and high-frequency ripple current of 2.381 A at 50 kHz, suitable for continuous ripple applications.
• Long Life at Elevated Temperature — Endurance specified at 3000 hours when subject to rated ripple current at 105°C, demonstrating sustained performance under elevated-temperature stress.
• Wide Operating Temperature Range — Specified for operation from −40°C to +105°C.
• Snap-In Mounting, Radial Can — Snap-in terminal type in a radial, snap-in metal can for secure board attachment and mechanical stability; supplied in tray packing for production handling.
• Leakage Current — Specified leakage current of 1230 µA (measured condition provided in the product data).
• RoHS Compliant — Meets RoHS requirements as noted in the product information.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing in power supplies where 63 V ratings and multi-amp ripple handling are required.
• Industrial electronics — Filtering and decoupling in control and drive systems that operate across −40°C to +105°C and require long endurance at elevated temperature.
• Power conversion modules — DC link and output filtering in converters where high ripple current capability and stable capacitance over life are important.

Unique Advantages

• High ripple handling with specified endurance — 2.07 A (120 Hz) and 2.381 A (50 kHz) ripple ratings combined with 3000 hours endurance at 105°C deliver reliable performance under continuous ripple stress.
• Thermal robustness — Rated operation from −40°C to +105°C and series-level endurance data for 3000 hours at 105°C enable use in thermally challenging installations.
• Compact, serviceable package — φ22 × 40 mm snap-in can offers a balance of capacitance and board-level footprint for space-conscious designs; tray packing supports production assembly.
• Quantified electrical characteristics — Explicit specifications for tan δ (0.25), leakage current (1230 µA), and tolerance (±20%) allow accurate selection and predictable circuit behavior.
• Regulatory compliance — RoHS compliance helps meet environmental and supply-chain requirements.
