LLS2G391MELC

The LLS2G391MELC from Nichicon is a snap‑in aluminum electrolytic capacitor in the LLS series designed for general‑purpose power applications. It provides 390 µF of capacitance at a 400 V rating in a radial, snap‑in can package.

Engineered for sustained operation, the part is specified for 3000 hours at 85°C with rated ripple current applied and delivers measurable ripple handling and leakage performance suitable for a wide range of high‑voltage designs.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 400 V rated voltage for high‑voltage bulk energy storage and filtering.
• Capacitance Tolerance — Specified tolerance of −20% to +20% (±20% at 120 Hz, 20°C) for predictable design margins.
• Endurance — Rated for 3000 hours at 85°C when subjected to DC bias plus rated ripple current, meeting the LLS series endurance specification.
• Ripple Current Capability — Low‑frequency ripple current 2.28 A at 120 Hz and high‑frequency ripple current 3.26 A at 50 kHz to support demanding ripple environments.
• Electrical Loss (tan δ) — Loss tangent (tan δ) 0.15 measured at 20°C, 120 Hz for stable AC loss characteristics.
• Leakage Current — Specified leakage current of 1180 µA for this nominal capacitance and voltage.
• Package & Mounting — Radial, snap‑in can (φ35×35 L) offered in tray packing for straightforward panel/chassis mounting and assembly.
• Operating Temperature — Rated for −25°C to +85°C operation consistent with the 350–450 V category range in the LLS series.
• RoHS Compliance — Compliant to the RoHS directive as noted for the LLS series.

Typical Applications

• General Purpose Power Electronics — Bulk capacitance and 400 V rating for designs that require high‑voltage energy storage and smoothing.
• High‑Ripple Environments — Suitable where rated ripple currents of 2.28 A (120 Hz) and 3.26 A (50 kHz) are required for reliable operation.
• Chassis/Panel Mount Assemblies — Snap‑in radial can and tray packaging facilitate secure mechanical mounting and assembly in equipment enclosures.

Unique Advantages

• High‑Voltage Bulk Capacitance: 390 µF at 400 V provides substantial stored energy per component for high‑voltage systems.
• Long Endurance Under Load: Designed to withstand 3000 hours at 85°C with rated ripple current, supporting longevity in sustained operating conditions.
• Measured Ripple Handling: Rated ripple current figures at both low and high frequencies let designers match component selection to switching and line conditions.
• Snap‑In Mechanical Format: Radial snap‑in can simplifies secure mounting in power assemblies and panel installations.
• Defined AC Loss Performance: Low tan δ (0.15 at 20°C, 120 Hz) gives predictable AC loss and heating behavior for thermal planning.
• Regulatory Compliance: RoHS compliance supports designs targeting restricted‑substance conformance.
