LLS2D331MELZ

The LLS2D331MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LLS series, featuring a 330 µF capacitance and 200 V rated voltage for general-purpose power electronics. It is designed for applications that require bulk energy storage and filtering with robust ripple-current handling and long endurance.

Key attributes include snap-in radial can mounting, a -40°C to +85°C operating range, RoHS compliance, and an endurance rating of 3000 hours at 85°C—making it suitable for sustained operation in industrial and power-conversion environments.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable bulk storage and filtering.
• Voltage Rating — 200 V rated voltage to support higher-voltage power rails and energy-storage duties.
• Ripple Current Capability — 1510 mA at 120 Hz (low frequency) and 2265 mA at 50 kHz (high frequency) to handle switching and AC ripple stress common in power supplies.
• Low Loss — tan δ of 0.15 (max) measured at 20°C and 120 Hz to minimize dissipation and self-heating under AC conditions.
• Leakage Current — Specified leakage current of 770 µA for predictable stand-by behavior after voltage application.
• Endurance & Reliability — Rated for 3000 hours at 85°C under rated ripple and DC bias, with capacitance and tan δ limits defined for end-of-life performance.
• Package & Mounting — Radial, snap‑in can (φ22 × 25 L / 2.2 × 2.5 cm) for secure chassis or PCB-mounted installations and simplified assembly.
• Environmental Compliance — RoHS compliant as specified in the product data.

Typical Applications

• Switch‑mode power supplies — Bulk smoothing, hold‑up and output filtering on 200 V rails where high ripple current capability and stable capacitance are required.
• Industrial power conversion — Energy storage and DC link filtering for motor drives and inverters that operate within the −40°C to +85°C temperature window.
• Uninterruptible power supplies (UPS) and backup systems — Bulk capacitor for energy buffering and smoothing during transient loads and power transitions.
• General-purpose power electronics — Filtering and decoupling in equipment where a snap-in radial can and long endurance (3000 h at 85°C) are advantageous.

Unique Advantages

• High ripple tolerance: Specified 1.51 A (120 Hz) and 2.265 A (50 kHz) ripple currents reduce thermal stress in switching environments.
• Extended endurance: 3000-hour rating at 85°C under rated ripple current supports continuous-duty applications.
• Low dissipation factor: tan δ = 0.15 at 120 Hz lowers power loss and heating during AC operation.
• Compact snap‑in package: φ22 × 25 mm can provides a space-efficient, secure mounting option for chassis and PCB assemblies.
• Predictable leakage behavior: 770 µA leakage current specification aids in reserve-power and standby designs.
• RoHS compliant: Meets environmental requirements for regulated markets.
