LLS2V561MELB

The LLS2V561MELB is a snap-in terminal aluminum electrolytic capacitor rated at 350V with 560µF capacitance and ±20% tolerance. It is a polarized, radial can (snap-in) device designed for general-purpose power applications where high-voltage smoothing, bulk energy storage and sustained ripple handling are required.

Key value propositions include robust ripple-current capability at both low and high frequencies, a 3000-hour endurance at 85°C under rated ripple, and RoHS compliance, making it suitable for production designs requiring predictable electrical performance and long-term reliability.

Key Features

• Core Electricals 560 µF capacitance at 350 VDC with ±20% tolerance, suitable for high-voltage bulk decoupling and energy storage.
• Ripple Current Performance Supports 2.73 A ripple current at 120 Hz (low frequency) and 3.904 A at 50 kHz (high frequency), enabling effective ripple dissipation across power-conversion bandwidths.
• Loss and Leakage Low dissipation factor: tanδ 0.15 measured at 20°C and 120 Hz; leakage current specified at 1320 µA for predictable no-load behavior.
• Endurance and Stability Rated for 3000 hours at 85°C with D.C. bias plus rated ripple current; after test the capacitor meets capacitance, tanδ and leakage limits defined in the datasheet endurance criteria.
• Operating Environment Specified operating temperature range of −25°C to +85°C for the 350V rating, suitable for many industrial and commercial applications.
• Mechanical and Mounting Snap-in terminal, radial can package (φ30 × 40L / approx. 4 × 3 cm), tray packing for production handling and board-level retention.
• Regulatory RoHS compliant.

Typical Applications

• Power Supplies — Bulk smoothing and hold-up in high-voltage DC power supplies and converters where sustained ripple current and high working voltage are required.
• Industrial Drives — Energy storage and DC-link decoupling in motor drives and industrial power conversion systems operating up to 350V.
• Inverter and UPS Systems — Bulk capacitance for energy buffering and ripple suppression in inverter and uninterruptible power supply designs.

Unique Advantages

• High-voltage capability: 350 V rating provides headroom for high-voltage DC systems while maintaining 560 µF capacitance.
• Dual-frequency ripple handling: Specified ripple current at both 120 Hz and 50 kHz supports performance across line-frequency and switching-frequency domains.
• Long endurance at elevated temperature: 3000 hours at 85°C under rated ripple current supports predictable lifetime in continuous-duty applications.
• Measured electrical stability: Low tanδ (0.15 at 20°C/120 Hz) and defined leakage current enable reliable AC and DC performance characterization during design.
• Production-ready packaging: Tray packing and snap-in mounting simplify assembly and handling for mass production.
