LGG2W271MELC25

The LGG2W271MELC25 is a Nichicon LGG series snap‑in aluminum electrolytic capacitor rated at 270 µF and 450 V. It is a polarized, radial can with snap‑in terminals designed for general‑purpose use in equipment where a compact, high‑voltage electrolytic is required.

Designed as an ultra‑smaller‑sized 105°C snap‑in type, this part supports equipment downsizing while providing high temperature endurance and defined ripple performance for power systems and industrial electronics.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance at a 450 V rated voltage for high‑voltage filtering and energy storage in compact assemblies.
• Compact Snap‑in Package — Radial, can‑type snap‑in termination in a φ35×25L package suitable for secure chassis mounting and automated assembly; part of the LGG ultra‑smaller series designed for equipment downsizing.
• High Temperature Endurance — Rated operating temperature up to 105°C with an endurance specification of 2000 hours at 105°C under rated ripple and DC bias.
• Ripple Current Characteristics — Specified ripple current: 1.05 A at 120 Hz (low frequency) and 1.502 A at 100 kHz (high frequency), supporting smoothing and decoupling in power applications.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C, allowing predictable leakage behavior for design margining.
• RoHS Compliant — Conforms to RoHS requirements (2011/65/EU, (EU)2015/863), supporting regulatory compliance for commercial and industrial products.

Typical Applications

• General‑purpose power filtering — 270 µF at 450 V provides bulk filtering and smoothing in high‑voltage power rails and power supply stages where space is limited.
• Equipment downsizing — The LGG series’ ultra‑smaller case sizing makes this capacitor suitable for designs focused on reducing enclosure and board footprint.
• High‑temperature environments — Rated to 105°C with a 2000‑hour endurance, appropriate for products that require sustained operation at elevated temperatures.
• Mass production assembly — Snap‑in radial can and tray packing format support efficient chassis mounting and high‑volume manufacturing workflows.

Unique Advantages

• High voltage capability: 450 V rating enables use in higher‑voltage DC systems without stacking multiple components.
• Space‑saving form factor: Ultra‑smaller LGG series case (φ35×25L) helps reduce overall equipment size while maintaining capacitance.
• Designed for reliability at temperature: 2000 hours endurance at 105°C under rated conditions provides predictable long‑term performance.
• Defined ripple performance: Published ripple current figures at both 120 Hz and 100 kHz allow accurate thermal and lifetime calculations in design.
• Predictable leakage behavior: Leakage current specified by the I ≤ 3√CV (µA) rule enables conservative design margins for standby and idle conditions.
• RoHS compliance: Meets current RoHS directive requirements for environmentally conscious product designs.
