LGZ2W271MELC45

The LGZ2W271MELC45 from Nichicon is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose applications that require high voltage handling and extended operational life. It combines a 450 V rating with a 270 µF capacitance and a long-life endurance specification to support equipment requiring prolonged, reliable filtering and energy storage.

Engineered for sustained operation at elevated temperature, this LGZ series unit provides 20,000 hours of endurance at 105°C and a polarized snap-in can package sized φ35 × 45 mm for board-mounted power assemblies.

Key Features

• High Voltage Capability — 450 V rated voltage for high-voltage general-purpose circuits.
• Substantial Capacitance — 270 µF nominal capacitance with ±20% tolerance for bulk energy storage and smoothing.
• Long-Life Endurance — Rated for 20,000 hours of operation at 105°C under DC bias plus rated ripple current.
• Wide Operating Temperature — Specified for operation from −25°C to +105°C to support elevated-temperature environments.
• Snap-in Radial Package — Radial can with snap-in terminals and dimensions φ35 × 45 mm (L: 4.5 × D: 3.5 cm) for secure PCB mounting.
• Ripple Current Performance — Rated ripple current of 1.19 A (1,190 mArms) at 105°C, 120 Hz; frequency coefficient enables up to ~1.702 A at higher frequencies (50 kHz) for improved AC load handling.
• Leakage Current — Specified leakage current of 1,040 µA after rated voltage application, providing a clear baseline for design margins.
• RoHS Compliant — Meets RoHS directive requirements for environmental regulation compliance.

Typical Applications

• General-purpose power supply filtering — 450 V rating and 1.19 A ripple handling support high-voltage smoothing and decoupling in general-purpose equipment.
• Bulk energy storage in high-voltage circuits — 270 µF capacitance provides bulk charge storage where long discharge intervals or energy buffering are needed.
• Equipment requiring extended operational life — 20,000 h endurance at 105°C suits designs that prioritize long-term reliability in continuous-duty applications.

Unique Advantages

• Extended operational lifetime — 20,000 hours at 105°C increases mean time between maintenance for long-running equipment.
• High-voltage, high-capacity combination — 450 V and 270 µF together enable designs that need both voltage margin and substantial capacitance in one component.
• Robust ripple performance — Clear rated ripple currents at low and high frequencies let designers size thermal and cooling margins accurately.
• Compact snap-in form factor — φ35 × 45 mm snap-in can simplifies PCB mounting while delivering high-voltage capability in a manageable footprint.
• Predictable leakage baseline — Specified leakage current (1,040 µA) gives engineers a verifiable parameter for worst-case analysis.
• Regulatory compliance — RoHS compliance supports environmentally conscious product designs.
