LLS2V181MELY

The LLS2V181MELY is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose power applications. It combines a 350 V rated voltage with 180 µF capacitance in a compact snap-in can (φ20 × 35 mm) and is specified for continuous operation from −25°C to 85°C.

Engineered for sustained ripple-handling and long endurance, this part delivers measurable performance for designs that require high-voltage bulk capacitance with RoHS-compliant construction and tray packing for production deployment.

Key Features

• Electrical Rating — 180 µF capacitance at a 350 V rated voltage with ±20% tolerance, providing high-voltage bulk capacitance for power circuits.
• Ripple Current Capability — Low-frequency ripple current of 1.24 A at 120 Hz and high-frequency ripple current of 1.7732 A at 50 kHz, enabling effective AC ripple handling and smoothing.
• Loss and Leakage — Specified tangent of loss angle (tan δ) of 0.15 at 120 Hz and a leakage current of 750 µA, allowing predictable dissipation and leakage behavior in designs.
• Endurance and Reliability — Rated for 3000 hours endurance at 85°C with rated ripple and DC bias applied, maintaining capacitance within ±20% and leakage at or below initial specified values after the endurance test.
• Operating Range — Specified for operation from −25°C to 85°C (350 V rating), suitable for standard temperature environments within that range.
• Package and Mounting — Snap-in terminal, radial can package (φ20×35 mm), supplied in tray packing for efficient assembly and mass production status.
• Environmental Compliance — RoHS compliant, meeting current restricted-substance requirements.

Typical Applications

• Power supply bulk filtering — High voltage rating and large capacitance make this capacitor suitable for smoothing and bulk energy storage in power conversion stages.
• Ripple and noise suppression — Specified ripple current at both low and high frequencies supports AC ripple attenuation in DC-link and filter networks.
• Industrial power electronics — Endurance at 85°C and snap-in mounting support robust assembly in industrial power modules and assemblies.
• General-purpose electronic systems — RoHS-compliant construction and tray packing accommodate production use across varied general-purpose designs.

Unique Advantages

• High-voltage capability: 350 V rating provides large DC-headroom for high-voltage power circuits.
• Measurable ripple performance: Separate low- and high-frequency ripple current specifications (1.24 A at 120 Hz, 1.7732 A at 50 kHz) let designers quantify ripple handling for specific frequency bands.
• Proven endurance: 3000 hours at 85°C under rated ripple and DC bias ensures long-term stability of capacitance and leakage within specified limits.
• Predictable dielectric losses: tan δ of 0.15 at 120 Hz allows accurate thermal and loss budgeting in designs.
• Production-ready packaging: Tray packing and snap-in terminals simplify handling and integration for mass production lines.
• Regulatory alignment: RoHS compliance supports deployment in regions requiring restricted-substance adherence.
