LLG2W271MELZ45

The LLG2W271MELZ45 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal (radial can) package, specified at 270 µF and 450 V. It is designed as a one-rank smaller case than the LLS series, making it suited for equipment downsizing while retaining high-voltage capability.

Targeted for general-purpose applications, this polarized capacitor delivers defined ripple handling and endurance characteristics for power filtering and energy storage in commercial and industrial equipment. The device is RoHS compliant and optimized for reliable operation across its rated conditions.

Key Features

• Electrical performance — Rated capacitance 270 µF at 450 V with a capacitance tolerance of −20% to +20% for predictable circuit behavior.
• Ripple handling — Rated ripple current of 1.66 A at 120 Hz and 2.374 A at 100 kHz, enabling effective filtering under AC ripple conditions.
• Package & mounting — Snap-in (radial, can) construction for secure PCB installation; compact footprint L: 4.5 × D: 2.2 cm to support equipment downsizing (one rank smaller than LLS).
• Thermal and operating range — Rated for operation from −25 °C to +85 °C at the 450 V rating.
• Endurance and reliability — Specified endurance of 2000 hours at 85 °C with DC bias plus rated ripple current; after the test the capacitor meets limits for capacitance change (±20%), tan δ, and leakage current.
• Leakage current specification — Leakage current conforms to I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20 °C, providing a verifiable leakage limit for design validation.
• Dielectric loss (tan δ) — Maximum tan δ of 0.20 at the 450 V rating (measured at 120 Hz, 20 °C), enabling designers to account for dissipation at rated conditions.
• Environmental compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), meeting regulatory requirements for restricted substances.
• Marking — Printed with white lettering on a black sleeve for clear identification.

Typical Applications

• General-purpose power supplies — Bulk smoothing and ripple filtering in AC/DC and DC/DC converters where 450 V rating and defined ripple current capability are required.
• Industrial power equipment — Energy storage and filtering in commercial and industrial control systems that benefit from a compact, high-voltage snap-in capacitor.
• Equipment downsizing projects — Replacement or redesign applications that demand a smaller case size than LLS while retaining high-voltage capacitance.

Unique Advantages

• Compact, downsizing-friendly form factor: One rank smaller case than LLS with a 4.5 × 2.2 cm footprint, allowing reduced board space for high-voltage capacitors.
• High-voltage capability: 450 V rating paired with 270 µF capacitance supports designs that require mid-range capacitance at elevated voltages.
• Validated ripple performance: Specified ripple currents at 120 Hz and 100 kHz give clear parameters for EMI filtering and power smoothing design margins.
• Defined endurance characteristics: 2000 hours at 85 °C under DC bias plus rated ripple current with documented post-test limits for capacitance, tan δ, and leakage current.
• Predictable leakage behavior: Leakage current limited by the I ≤ 3√CV formula after rated-voltage application, simplifying leakage budgeting in designs.
• Regulatory readiness: RoHS compliance provides environmental assurance for commercial and industrial product lines.
