LGU2D391MELA

The LGU2D391MELA is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose applications. It delivers 390 µF nominal capacitance at a 200 V rating with a compact φ25 × 25 mm can and snap-in mounting.

This part is specified for sustained ripple operation and long-term endurance at elevated temperature, making it suitable where reliable DC filtering and bulk capacitance are required in board-mounted power subsystems.

Key Features

• Capacitance & Tolerance — 390 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 200 V DC rating for higher-voltage power rails.
• Low Loss (tan δ) — tan δ 0.15 (max) at 20°C, 120 Hz for the 160–420 V category; specified value 0.15 at 20°C, 120 Hz for this part.
• High Ripple Capability — 1.35 A low-frequency ripple current at 120 Hz and 2.025 A high-frequency ripple current at 50 kHz, supporting sustained AC ripple handling.
• Leakage Current — 830 µA specified leakage current after rated voltage application (20°C, 5 minutes).
• Endurance & Temperature — Rated for 3000 hours at 105°C with DC bias plus rated ripple current; operating temperature range −40°C to +105°C.
• Package & Mounting — Radial snap-in can (φ25 × 25L) for secure board installation; tray packing for production handling.
• Compliance & Production Status — RoHS compliant and in mass production.
• Polarized Device — Designed as a polarized aluminum electrolytic capacitor.

Typical Applications

• General-purpose power filtering — Bulk capacitance and ripple handling for DC power rails where a 200 V rating and high ripple current are required.
• Power supply energy storage — Smoothing and energy buffering in board-mounted power subsystems using snap-in mounting for secure mechanical retention.
• Industrial and commercial electronics — Applications that require long endurance at elevated temperature (3000 hours at 105°C) and RoHS compliance.

Unique Advantages

• High-voltage capability: 200 V rating enables use on higher-voltage DC rails without stacking capacitors.
• Robust ripple performance: Specified ripple currents at both low and high frequencies support reliable operation under sustained AC load.
• Long endurance at 105°C: 3000-hour rating under rated ripple and bias conditions provides predictable lifetime behavior in hot environments.
• Compact snap-in form factor: φ25 × 25 mm can with snap-in terminals offers a space-efficient solution for board-level mounting with secure mechanical retention.
• Production-ready packaging: Tray packing and mass production status simplify procurement and assembly planning.
• Regulatory compliance: RoHS compliance helps meet environmental requirements for commercial products.
