LLS2G331MELB

The LLS2G331MELB is a Nichicon LLS series aluminum electrolytic capacitor in a snap‑in terminal can, rated 400 V and 330 µF with polarized construction. It is designed for general‑purpose power applications that require high voltage handling and bulk capacitance in a snap‑in, radial can package.

Key value propositions include a 3000‑hour endurance at 85°C, RoHS compliance, low dissipation factor (tanδ), and specified ripple current performance across low and high frequencies—making it suitable for long‑life power filtering and energy storage roles in mass production assemblies.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance at a 400 V rated voltage, providing bulk energy storage for high‑voltage circuits.
• Tolerance: ±20% capacitance tolerance at 120 Hz, 20°C, permitting predictable performance in design margins.
• Dissipation Factor (tanδ): Specified tanδ of 0.15, supporting low loss operation at the measurement conditions indicated.
• Endurance: Rated for 3000 hours at 85°C under DC bias plus rated ripple current, with defined limits for capacitance change, tanδ, and leakage after the test.
• Ripple Current Performance: 2.05 A at 120 Hz and 2.932 A at 50 kHz, enabling handling of both low‑ and higher‑frequency ripple in power systems.
• Temperature Range: Operating temperature range of −25°C to +85°C, aligned with the 400 V rating for stable performance in that window.
• Mounting & Package: Snap‑in radial can package (φ30×35L, tray packing) for secure board attachment and efficient mass production handling.
• Regulatory Compliance: RoHS‑compliant construction as part of the LLS series.

Typical Applications

• General Purpose Power Filtering: Bulk smoothing and decoupling in high‑voltage power supplies and converters where a 400 V, 330 µF polarized capacitor is required.
• Energy Storage for Power Electronics: Local energy reservoir for DC link or intermediate storage in industrial power assemblies operating within −25°C to +85°C.
• Mass Production Assemblies: Snap‑in radial can format and tray packing support high‑volume manufacturing and assembly processes.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in elevated DC bus and power supply applications where lower‑voltage capacitors are insufficient.
• Long Endurance at Elevated Temperature: 3000 hours at 85°C provides predictable lifetime performance for sustained thermal stress conditions.
• Frequency‑rated Ripple Handling: Specified ripple current values at 120 Hz and 50 kHz allow designers to size capacitors based on actual ripple spectra.
• Snap‑in Mechanical Retention: Radial, snap‑in can package simplifies board retention and assembly for high‑volume production.
• Low Dissipation Factor: tanδ = 0.15 supports efficient operation with reduced dielectric loss under the measured conditions.
• RoHS Compliance: Meets RoHS requirements for environmentally restricted substances.
