LGR2D271MELA25

The LGR2D271MELA25 is an aluminum electrolytic capacitor in a snap-in radial can package, offering 270 µF capacitance at a 200 V rating. It is part of Nichicon's LGR Long Life Assurance series designed for extended operation at elevated temperatures.

Engineered for general-purpose applications, this polarized capacitor provides high ripple-current capability and long-term endurance up to 105°C, with RoHS compliance for regulated environments.

Key Features

• Capacitance & Voltage — Rated at 270 µF and 200 V with a tolerance of ±20% to meet bulk energy storage and decoupling needs.
• High-temperature, Long Life — Rated operating temperature range is −40°C to +105°C, and the part withstands 10,000 hours of ripple-current application at 105°C per the LGR series specifications.
• Ripple Current Performance — Rated ripple current of 1.1 A at 120 Hz and 1.65 A at 50 kHz for frequency-dependent ripple handling.
• Package & Mounting — Snap-in terminal, radial can package sized 25 × 25 mm (L × D) for secure board mounting and mechanical stability.
• Electrical Losses & Leakage — Maximum tan δ for the 200–400 V range is 0.15; typical leakage current listed as 0.69 mA for this size in the LGR series dimension table.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power applications — Use where 270 µF at 200 V is required for bulk capacitance, smoothing or energy storage in general-purpose designs.
• High-temperature installations — Suitable for circuits that require sustained operation up to 105°C with verified 10,000-hour ripple endurance.
• Board-level snap-in assemblies — Radial, snap-in can format simplifies secure PCB mounting and assembly in equipment chassis.

Unique Advantages

• Verified long-term endurance — Endurance tested for 10,000 hours at 105°C under rated ripple and DC bias conditions, supporting reliable high-temperature operation.
• Frequency-aware ripple capability — Specified ripple current ratings at 120 Hz and 50 kHz allow designers to size capacitors against actual operating frequencies.
• Compact, robust package — 25 × 25 mm radial snap-in can provides a balance of capacitance and board space for power assemblies.
• Clear electrical limits — Documented tan δ and leakage current figures enable predictable performance and easier thermal/electrical budgeting.
• RoHS compliance — Meets current RoHS directive requirements for restricted substances.
