LGW2W271MELC30

The LGW2W271MELC30 is a snap‑in, aluminum electrolytic capacitor in Nichicon’s LGW series designed for general‑purpose applications that require high ripple handling and high‑temperature endurance. It provides 270 µF of capacitance at a 450 V rating, with RoHS compliance and a snap‑in radial can package for secure PCB mounting.

This part is specified for continuous operation up to 105 °C and is endurance‑tested for long operation under rated ripple conditions, making it suitable for designs that need high voltage energy storage and sustained ripple current performance.

Key Features

• Electrical Capacity — 270 µF nominal capacitance at a rated voltage of 450 V with polarization for DC applications.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20 °C (specified as –20% to +20%).
• High Ripple Current — Specified ripple current of 1.9 A at 120 Hz and 2.717 A at 50 kHz, with frequency coefficients provided in the datasheet for other frequencies.
• Thermal and Endurance Rating — Operating temperature range of –25 °C to 105 °C and endurance characterized for 3000 hours at 105 °C when DC bias plus rated ripple current is applied.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20 °C, per datasheet test conditions.
• Package & Mounting — Radial can, snap‑in terminal type for robust PCB anchoring and simplified assembly.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Unique Advantages

• High‑voltage energy storage: 270 µF at 450 V delivers significant DC link or bulk capacitance in a compact snap‑in package.
• Validated ripple endurance: Endurance testing for 3000 hours at 105 °C under rated ripple current offers predictable long‑term performance under continuous ripple stress.
• Frequency‑characterized ripple behavior: Datasheet includes frequency coefficients and specific ripple current values (1.9 A at 120 Hz; 2.717 A at 50 kHz) to allow accurate thermal and ripple budgeting in designs.
• Defined leakage performance: Leakage current limit I ≤ 3√CV (µA) gives a clear, testable specification for power‑up and standby loss calculations.
• Robust operating range: Rated for –25 °C to 105 °C in the 400–450 V category, matching higher‑temperature end uses within general‑purpose systems.
• Compliance and traceability: RoHS compliance and Nichicon LGW series documentation provide regulatory clarity and supporting datasheet details for design validation.
