LGU2F331MELA

The LGU2F331MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 330 µF capacitance at a 315 V rating. It is a radial, can‑type snap‑in capacitor designed for general‑purpose applications that require robust ripple handling and extended high‑temperature endurance.

Key technical strengths include a wide operating temperature range of −25°C to 105°C, endurance of 3000 hours at 105°C under rated ripple conditions, and RoHS compliance—making it suitable for production deployment where long life and regulatory compliance are required.

Key Features

• Electrical Performance — 330 µF nominal capacitance with a rated voltage of 315 V and capacitance tolerance of ±20% (measured at 20°C, 120 Hz).
• Loss Characteristics — Low loss tangent with tan δ ≤ 0.15 measured at 20°C, 120 Hz for the 315 V class, supporting efficient filtering and energy storage.
• Ripple Current Capability — Designed for high ripple environments: 1.33 A at 120 Hz (low frequency) and 1.902 A at 50 kHz (high frequency), enabling reliable performance across a range of switching and line frequencies.
• Leakage Current — Low leakage current specified at 960 µA after standard voltage application, suitable for power applications where standby loss matters.
• Thermal and Endurance — Rated for −25°C to 105°C operation with an endurance specification of 3000 hours at 105°C under rated ripple current and DC bias conditions.
• Mechanical and Packaging — Snap‑in terminal radial can (φ25×40L) with tray packing for ease of handling and production assembly.
• Compliance and Availability — RoHS‑compliant construction and currently in mass production.

Typical Applications

• General‑purpose power supplies — Bulk energy storage and smoothing in circuits requiring a 315 V rating and substantial ripple handling.
• Industrial power electronics — Applications that demand extended high‑temperature endurance (3000 hours at 105°C) and reliable ripple performance.
• Power conversion modules — Use where radial snap‑in mounting and compact can‑style packaging (4.0 cm × 2.5 cm) support robust board assembly and serviceability.

Unique Advantages

• High‑voltage capability: 315 V rated voltage provides margin for medium‑voltage power rails and bulk storage.
• Proven high‑temperature endurance: 3000 hours at 105°C under rated conditions supports long field life in thermally demanding environments.
• Strong ripple performance: Measured ripple current ratings at both low and high frequencies allow designers to rely on the part across switching and line frequencies.
• Compact, production‑friendly package: Snap‑in radial can in tray packing simplifies insertion and handling for through‑hole assembly processes.
• Regulatory readiness: RoHS compliance supports deployment in regions with restricted substance requirements.
