LGN2P391MELA25

The LGN2P391MELA25 is an aluminum electrolytic capacitor in a snap‑in terminal package, designed for general‑purpose electronic applications. It delivers 390 µF at 220 V with polarized construction and a compact radial can form factor.

Engineered for elevated operating temperatures, this part supports operation up to 105°C with 3000 hours of endurance under rated ripple current, offering a compact, high‑temperature solution where sustained ripple handling and board‑level snap‑in mounting are required.

Key Features

• Core Electrical: 390 µF capacitance at a rated voltage of 220 V with polarization and ±20% tolerance for predictable energy storage and filtering characteristics.
• High‑Temperature Endurance: Rated for operation from −40 °C to 105 °C and specified for 3000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple Current Capability: Ripple current ratings of 1.34 A at 120 Hz and 2.01 A at 100 kHz enable sustained ripple handling in demanding circuits.
• Compact Snap‑in Package: Radial, can‑snap‑in mounting with a compact footprint (L: 2.5 × D: 2.5 cm) for board‑level assemblies; physically one rank smaller case size than the LGU series.
• Reliability Metrics: Endurance and shelf‑life characteristics meet specified limits for capacitance change, tan δ, and leakage current after specified stress and storage conditions.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental requirements.

Typical Applications

• General‑purpose electronic equipment: Bulk capacitance and energy storage where a 390 µF, 220 V polarized capacitor is required.
• High‑temperature assemblies: Applications that need operation up to 105 °C with proven 3000‑hour endurance under rated ripple current.
• Board‑level power modules: Snap‑in mounting and a compact 2.5 × 2.5 cm package simplify integration into power assemblies and chassis‑mounted boards.

Unique Advantages

• Extended high‑temperature life: Specified 3000 hours at 105 °C under rated conditions, providing predictable long‑term performance in elevated environments.
• Sustained ripple handling: Dual ripple ratings (1.34 A at 120 Hz and 2.01 A at 100 kHz) support designs exposed to both low‑ and high‑frequency ripple currents.
• Space‑efficient footprint: Compact radial snap‑in can with one rank smaller case size than LGU, enabling tighter packing in power assemblies.
• Clear specification set: Defined temperature range, tolerance, leakage, and endurance limits make design verification and lifetime planning straightforward.
• Environmentally compliant: RoHS compliance supports regulatory and supply‑chain requirements for many electronic products.
