LGU2E391MELA

The LGU2E391MELA is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic applications. It combines a 250 V rated voltage with 390 µF capacitance in a radial, snap-in can package and is supplied in tray packing for production use.

Engineered for robust thermal and ripple performance, this part supports an operating temperature range of –40°C to 105°C and is specified for 3,000 hours endurance at 105°C, providing verifiable reliability for long-life designs.

Key Features

• Rated Capacitance & Tolerance — 390 µF with ±20% tolerance at 120 Hz, 20°C.
• High Voltage Rating — 250 V nominal working voltage suitable for mid-voltage power sections.
• Snap‑In, Radial Can Package — Snap-in terminal type with radial can construction for secure board mounting and straightforward assembly.
• Thermal Endurance — Rated for 3,000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Ripple Current Capability — 1,490 mA at 120 Hz (low frequency) and 2,235 mA at 50 kHz (high frequency), supporting applications with significant AC ripple demands.
• Loss and Leakage — Specified tan δ of 0.15 (max) at 20°C, 120 Hz for the 160–250 V category, and a measured leakage current of 930 µA.
• Environmental Compliance — RoHS compliant.
• Form Factor — Physical size: φ25 × 35L (L: 3.5 cm × D: 2.5 cm), polarized device.
• Production Status & Packing — Mass production availability with tray packing.

Typical Applications

• General-Purpose Power Electronics — Suitable for general-purpose circuits where a 250 V, 390 µF polarized capacitor is required.
• Industrial Electronics — Designed for applications that demand 105°C endurance and defined ripple current capability.
• Board-Level Power Modules — Snap-in radial can package provides a robust mounting option for high-capacitance sections on power PCBs.

Unique Advantages

• Clear ripple-current specification: Defined low- and high-frequency ripple current ratings (1.49 A at 120 Hz; 2.235 A at 50 kHz) let engineers size capacitors against measured AC stress.
• Long thermal life: 3,000 hours endurance at 105°C provides a measurable reliability baseline for thermal-stress designs.
• Compact mid-voltage solution: 250 V rating with 390 µF capacitance in a φ25 × 35 mm package balances energy storage and board area.
• Verified electrical characteristics: Specified tan δ and leakage current figures allow predictable performance in filtering and smoothing roles.
• Production-ready packaging: Tray packing and mass production status support high-volume assembly workflows.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements.

Why Choose LGU2E391MELA?

The LGU2E391MELA positions itself as a reliable, production-ready aluminum electrolytic solution for designers needing a 250 V, 390 µF polarized capacitor with defined ripple, leakage and loss-angle characteristics. Its 3,000-hour endurance at 105°C and snap-in radial can form factor make it suitable for long-life, board-mounted power circuits where thermal and ripple demands are specified.

This part is appropriate for engineering and procurement teams seeking verifiable electrical and environmental data—tangible metrics such as ripple current ratings, tan δ, leakage current, operating temperature range, and RoHS compliance reduce ambiguity during component selection and qualification.
