LGU2G151MELA

The LGU2G151MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It is a polar, radial can (snap‑in) capacitor rated at 400 V with a nominal capacitance of 150 µF and ±20% tolerance.

Designed for general purpose applications, this part combines a compact φ25 × 30 mm footprint with a high voltage rating, defined ripple current performance, and a long endurance specification for use where a 400 V snap‑in electrolytic is required.

Key Features

• Core electrical — 150 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage provides a high‑voltage energy storage option in a compact snap‑in can.
• Loss characteristics — Specified tanδ of 0.15 at 20°C and 120 Hz for the 160–420 V rating range, supporting predictable dissipation characteristics at rated conditions.
• Ripple current capability — 880 mA low‑frequency ripple current at 120 Hz and 1.258 A high‑frequency ripple current at 50 kHz, enabling defined AC stress performance for filtering and smoothing in specified operating conditions.
• Leakage current — Specified leakage current of 730 µA after standard voltage application, for predictable standby and bias behaviour.
• High endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current, meeting the LGU series endurance criteria when restored to 20°C.
• Mechanical and mounting — Snap‑in terminal, radial can package (φ25 × 30 mm), supplied in tray packing for production handling and assembly.
• Operating temperature — Specified operating range of −25°C to +105°C for the 315–450 V rated parts in the LGU series.
• Regulatory — RoHS‑compliant per the provided product information.

Typical Applications

• General‑purpose electronics — Intended for general purpose applications that require a 400 V, 150 µF snap‑in aluminum electrolytic capacitor with defined ripple and endurance characteristics.
• High‑voltage, elevated‑temperature environments — Suitable where a 400 V rated capacitor must operate up to 105°C and meet 3000 hours endurance at that temperature.
• Production volumes — Tray packing and mass production status make this part suitable for repeatable manufacturing and assembly workflows.

Unique Advantages

• High voltage capability: 400 V rating provides the ability to support higher DC bus voltages within general purpose designs.
• Defined ripple performance: Specified low‑ and high‑frequency ripple current values (880 mA at 120 Hz; 1.258 A at 50 kHz) enable designers to size capacitors for expected AC stress.
• Long‑term endurance: 3000 hours at 105°C under rated conditions delivers predictable life performance for sustained elevated‑temperature operation.
• Compact snap‑in package: φ25 × 30 mm radial can with snap‑in terminals simplifies board mounting and mechanical retention in through‑hole assembly.
• Regulatory compliance: RoHS compliance supports use in designs requiring restricted‑substance conformity.
• Production ready: Tray packing and mass production status facilitate procurement and volume assembly planning.
