LLS2V331MELB

The LLS2V331MELB is an aluminum electrolytic capacitor in Nichicon’s LLS series featuring a snap‑in terminal package. It delivers 330 µF capacitance at a 350 V rated voltage with a ±20% tolerance and is specified for general‑purpose applications.

Designed for applications that require high voltage bulk capacitance with robust ripple handling and long endurance, this snap‑in, radial can offers a compact φ30×30L form factor and is available in tray packing for mass production.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated at 350 V with ±20% tolerance for reliable bulk energy storage.
• Snap‑in Radial Package — Snap‑in terminal, radial can package (φ30×30L) for secure board mounting and mechanical stability.
• Ripple Current Performance — Rated ripple current of 2.03 A at 120 Hz (low frequency) and 2.903 A at 50 kHz (high frequency) to support sustained AC loading.
• Loss Tangent (tan δ) — tan δ of 0.15 (measured at 20°C, 120 Hz) consistent with the 350 V rating for predictable ESR behavior.
• Leakage Current — Specified leakage current of 1010 µA after application of rated voltage, suitable for general‑purpose designs.
• Operating Range & Endurance — Operating temperature −25°C to +85°C with endurance of 3000 hours at 85°C under rated ripple and DC bias.
• Compliance & Production — RoHS compliant, tray packing, and listed as mass production status for volume deployment.

Typical Applications

• General‑Purpose Power Electronics — Provides bulk capacitance and ripple handling for a wide range of electronic equipment requiring 350 V DC support.
• Industrial Equipment — Suited to general‑purpose industrial circuits where long endurance at elevated temperature (3000 h at 85°C) is required.
• Power Supply Filtering — Used for smoothing and energy storage in power conversion stages that need high voltage capacitance and sustained ripple current capability.

Unique Advantages

• High Voltage Capability: 350 V rating allows integration into higher‑voltage DC systems without series stacking.
• Robust Ripple Handling: Dual ripple current specifications (2.03 A at 120 Hz and 2.903 A at 50 kHz) support both low‑ and high‑frequency AC components.
• Long Endurance: 3000 hours at 85°C under rated conditions provides predictable aging behavior for longer service intervals.
• Stable Loss Characteristics: tan δ = 0.15 at 20°C and 120 Hz (350 V) for consistent dissipation factor performance.
• Production‑Ready Packaging: Tray packing and mass production status simplify procurement and assembly planning.
• Regulatory Compliance: RoHS compliance for alignment with environmental requirements.
