LGU2G471MELC

The LGU2G471MELC is a snap‑in terminal type aluminum electrolytic capacitor designed for general‑purpose high‑voltage applications. With a 470 µF capacitance at a 400 V rating and a compact φ35×40 mm can, it provides high‑voltage bulk capacitance with robust ripple handling and extended endurance.

Engineered for sustained operation up to 105°C and compliant with RoHS, this part targets power supply filtering, high‑voltage smoothing and other designs that require reliable electrolytic performance in demanding thermal and ripple environments.

Key Features

• Electrical Performance — 470 µF nominal capacitance with ±20% tolerance and 400 V rated voltage for high‑voltage energy storage and smoothing.
• Low Loss — tanδ 0.15 (max) measured at 20°C and 120 Hz for the 160–420 V range, supporting efficient reactive performance.
• High Ripple Current Capability — 1.900 A at 120 Hz (low frequency) and 2.717 A at 50 kHz (high frequency) to handle significant AC ripple stress in power circuits.
• Leakage Current — 1300 µA specified leakage current after standard voltage application at 20°C.
• Thermal Endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current, with specified limits on capacitance change, tanδ and leakage after endurance testing.
• Package & Mounting — Radial, can-type snap‑in package (φ35 × 40L) for secure board or chassis mounting; supplied in tray packing and available in mass production.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• High‑Voltage Power Supplies — 400 V rating and 470 µF capacitance provide bulk smoothing and decoupling for high‑voltage rails and power conversion stages.
• Industrial Power Conversion — 105°C endurance and 3000 hour life at 105°C support continuous operation in thermally demanding industrial environments.
• Ripple‑Intensive Circuits — High ripple current ratings at both 120 Hz and 50 kHz suit applications with substantial AC ripple, such as power inverters and PFC stages.
• Chassis or Board Mounting — Snap‑in radial can and compact φ35×40 mm footprint simplify installation in power racks and assemblies.

Unique Advantages

• High‑Voltage Capability: 400 V rating allows use in higher DC bus and power supply designs without series stacking.
• Designed for High Ripple Stress: Specified ripple current at both low and high frequencies reduces overheating and extends operational stability under AC loading.
• Long Endurance at Elevated Temperature: 3000 hours life at 105°C provides predictable aging characteristics for long‑term deployments.
• Compact Snap‑In Form Factor: φ35×40 mm snap‑in can offers a space‑efficient solution for bulk capacitance while enabling robust mechanical retention.
• RoHS‑Compliant Production: Environmentally conscious manufacturing and materials consistent with regulatory requirements.
• Available in Mass Production: Tray packing and production status suitable for volume assembly and procurement planning.
