LLS2G331MELC

The LLS2G331MELC from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LLS series designed for general‑purpose power applications. It combines a 330 µF capacitance with a 400 V rated voltage in a radial, snap‑in can package suited for tray packing and mass production.

Engineered for sustained operation up to 85°C, this part offers long endurance under rated ripple current (3000 hours at 85°C) and is RoHS compliant, making it appropriate for industrial and power‑electronics designs that require high‑voltage bulk capacitance and reliable lifespan performance.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 400 V rated voltage, suitable where high DC bus voltage bulk capacitance is required.
• Package & Mounting — Radial, can-type snap‑in terminal construction for secure PCB mounting and compatibility with tray packing for volume assembly.
• Operating Temperature & Endurance — Rated for operation from −25°C to +85°C (specified for 350–450 V range) with endurance of 3000 hours at 85°C when subjected to DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 2.05 A at 120 Hz and 2.932 A at 50 kHz, enabling effective smoothing under both low‑ and high‑frequency conditions.
• Electrical Characteristics — Polarized electrolyte capacitor with capacitance tolerance of ±20% (at 120 Hz, 20°C) and leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C.
• Compliance & Marking — RoHS compliant; sleeve marked with white letters on a black sleeve for clear identification.
• Compact Footprint — Physical dimensions approximately φ35 × 30 mm (L: 3 cm × D: 3.5 cm), offering a compact solution for high‑voltage bulk capacitance.

Typical Applications

• Power supplies — Bulk smoothing and DC bus energy storage in high‑voltage power supply designs where a 400 V rated capacitor is required.
• Industrial power conversion — Energy buffering and ripple attenuation in industrial inverters and converters operating within the specified temperature range.
• Control equipment — Bulk filtering in control and drive systems that benefit from snap‑in mounting and long ripple endurance.

Unique Advantages

• High‑voltage capability: 400 V rating lets designers address higher DC bus requirements without paralleling lower‑voltage parts.
• Long ripple endurance: Specified to withstand 3000 hours of rated ripple current at 85°C, providing predictable lifetime behavior under continuous load.
• Dual‑frequency ripple support: Measured ripple current values at both 120 Hz and 50 kHz offer defined performance across common switching and line frequencies.
• Secure snap‑in mounting: Radial can with snap‑in terminals simplifies mechanical retention on PCBs for production environments.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance and easier global deployment.
• Clear identification: White-on-black sleeve marking supports straightforward part recognition during assembly and service.
