LGU2E471MELZ

The LGU2E471MELZ is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 470 µF capacitance at a 250 V rating in a radial snap‑in can (φ22 × 50 mm) optimized for high ripple and extended endurance.

Engineered for industrial and commercial power systems, this part provides high ripple current capability, long life at elevated temperature, and low loss characteristics for reliable bulk energy storage and smoothing duties.

Key Features

• Capacitance & Voltage: 470 µF rated at 250 V for bulk energy storage and filtering in medium‑voltage power rails.
• Tolerance: ±20% at 120 Hz and 20°C to simplify selection for power supply decoupling and smoothing.
• Low loss (tan δ): 0.15 (max) measured at 20°C and 120 Hz, supporting efficient performance with reduced heating under AC ripple conditions.
• High ripple current capability: 1.65 A at 120 Hz (low frequency) and 2.475 A at 50 kHz (high frequency) to handle significant AC stress in power converters and inrush events.
• Leakage current: 1020 µA specified, enabling predictable bias behavior after voltage application.
• Endurance: 3000 hours at 105°C with rated ripple current applied, demonstrating long operational life under elevated temperature and load.
• Operating temperature range: –40°C to 105°C for use across a wide ambient temperature span.
• Package and mounting: Radial, can — snap‑in package (tray packing) for robust mechanical retention in chassis and power assemblies.
• Compliance: RoHS compliant.

Typical Applications

• Power supply smoothing: Bulk capacitance and ripple handling for switch‑mode power supplies and linear regulators.
• Industrial power systems: Energy storage and filtering in industrial power modules and control cabinets.
• Inverters and motor drives: DC link and intermediate circuit smoothing where elevated ripple current capability and endurance are required.
• Commercial electronics: Durable bulk capacitor for UPS, power conversion, and other general‑purpose electronic equipment.

Unique Advantages

• High voltage capability: 250 V rating enables use in higher‑voltage power rails compared with lower‑voltage electrolytics.
• Designed for sustained stress: 3000 hours endurance at 105°C with applied rated ripple current supports long service life in thermally demanding installations.
• Strong ripple performance: Specified ripple currents of 1.65 A (120 Hz) and 2.475 A (50 kHz) reduce voltage excursion and heating in high‑stress AC environments.
• Predictable loss and leakage: Low tan δ (0.15 at 120 Hz, 20°C) and defined leakage current (1020 µA) make behavior under bias and AC conditions easier to model and manage.
• Secure mechanical mounting: Snap‑in radial can package provides stable retention for power assemblies and simplifies installation into chassis or PCB fixtures.
• Regulatory readiness: RoHS compliance supports use in regions requiring hazardous‑substance conformity.
