LGU2G151MELZ

The LGU2G151MELZ is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in terminal package, rated 150 µF at 400 V with ±20% tolerance. It is a high-voltage, snap-in radial can designed for general-purpose board-mounted use where sustained ripple endurance and high-temperature operation are required.

Key value propositions include a 105°C rated operating range with 3000 hours endurance at rated ripple, robust ripple-current capability across low and high frequencies, and RoHS compliance for regulated designs.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High-temperature Endurance — Rated for 3000 hours at 105°C under D.C. bias plus rated ripple current, meeting the LGU series endurance specification.
• Low Loss (tan δ) — Maximum tan δ of 0.15 at 20°C and 120 Hz for the 400 V rating, supporting stable AC performance.
• Ripple Current Handling — 880 mA at 120 Hz (low frequency) and 1.258 A at 50 kHz (high frequency), enabling effective filtering under high ripple conditions.
• Leakage Current — Specified leakage current of 730 µA after rated voltage application, supporting predictable bias behavior.
• Package & Mounting — Snap-in radial can (φ22 × 40 mm length) for secure board mounting; supplied in tray packing and available for mass production.
• Temperature & Compliance — Operating temperature range −25°C to +105°C and RoHS compliant for regulatory alignment.
• Polarized Design — Conventional polarized electrolytic construction for DC smoothing and bulk energy applications.

Typical Applications

• General-purpose power filtering — Snap-in mounting and high ripple capability make this capacitor suitable for board-level smoothing in high-voltage circuits where long-term endurance at elevated temperatures is required.
• High-voltage DC link and bulk storage — 400 V rating and 150 µF capacitance offer bulk energy reserve for power conversion stages within the specified temperature range.
• Industrial electronics — Designed for use in equipment that demands sustained ripple endurance at 105°C and stable loss characteristics at 120 Hz.

Unique Advantages

• Long-term thermal reliability: Endurance of 3000 hours at 105°C demonstrates sustained performance under elevated operating temperature and ripple stress.
• Measured AC performance: Low tan δ (0.15 at 120 Hz) and defined leakage current (730 µA) provide predictable behavior for AC and DC biased circuits.
• Broad ripple capability: Explicit ripple current ratings for both low and high frequencies (880 mA at 120 Hz, 1.258 A at 50 kHz) help designers size capacitors for realistic operating spectra.
• Board-ready form factor: Snap-in radial can (φ22 × 40 mm) simplifies PCB mounting and mechanical retention for high-voltage assemblies.
• Regulatory readiness: RoHS compliance supports deployment in regulated product lines and reduces material compliance risk.
