LGU2D271MELZ

The LGU2D271MELZ is an aluminum electrolytic capacitor in a snap-in terminal can from the Nichicon LGU series. This radial, snap-in device delivers 270 µF capacitance at a 200 V rating with a −40°C to 105°C operating range and tray packaging for handling and assembly.

Designed for general-purpose applications that require sustained ripple handling and long high-temperature endurance, the LGU2D271MELZ combines high ripple-current capability with 3000 hours endurance at 105°C to support reliable power-electronic designs.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a rated voltage of 200 V with a tolerance of −20% to +20%.
• High Temperature Endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current, meeting LGU series endurance specifications.
• Ripple Current Performance — Supports low-frequency ripple current of 1.1 A (120 Hz) and high-frequency ripple current of 1.65 A (50 kHz), enabling effective AC ripple handling across frequencies.
• Loss Characteristics — Low dissipation factor with tan δ of 0.15 measured at 20°C and 120 Hz (per part specification).
• Leakage Current — Specified leakage current of 690 µA, measured after application of rated voltage per product conditions.
• Packaging & Mounting — Snap-in radial can (φ22 × 25 mm) in tray packing for efficient automated or manual assembly.
• Compliance — RoHS compliant as indicated in product environmental specifications.

Typical Applications

• General-purpose power circuits — Bulk capacitance and energy storage in circuits that require 270 µF at 200 V with long-term high-temperature endurance.
• Power supply smoothing — Filtering and smoothing in power systems where specified ripple current handling (1.1 A at 120 Hz / 1.65 A at 50 kHz) is required.
• High-temperature environments — Designs operating up to 105°C that need capacitors qualified for extended endurance (3000 hours at 105°C).

Unique Advantages

• Proven high-temperature endurance: 3000-hour rating at 105°C under rated ripple current supports long-term reliability in hot operating conditions.
• Clear ripple specifications: Explicit low- and high-frequency ripple current ratings let designers size capacitors to meet AC stress and thermal constraints.
• Compact snap-in package: φ22 × 25 mm radial snap-in can offers a space-efficient solution for PCB-mounted power components.
• Measurable electrical characteristics: Specified tan δ (0.15 at 20°C, 120 Hz) and defined leakage current (690 µA) provide predictable loss and leakage behavior for design calculations.
• RoHS compliance: Meets RoHS directive requirements for material compliance in regulated markets.
• Tray packing for assembly: Packaged in trays to support handling and production workflows.
