LLS2W271MELC

The LLS2W271MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLS series, rated at 270 µF and 450 V. Designed for general-purpose applications, it offers a polarized, snap-in can package with tray packing for board-level power systems.

Key value comes from its high-voltage rating, measured loss tangent and specified ripple endurance: the part withstands rated ripple current for 3000 hours at 85°C while maintaining capacitance and leakage within specified limits.

Key Features

• Capacitance and Tolerance: 270 µF nominal with tolerance of −20% to +20% measured at 120 Hz, 20°C.
• Rated Voltage: 450 V DC rating suitable for high-voltage DC applications within the stated operating range.
• Ripple Endurance: Endurance of 3000 hours at 85°C with rated ripple current applied; low-frequency ripple current 1.9 A (120 Hz) and high-frequency ripple current 2.717 A (50 kHz).
• Dielectric Loss: tan δ = 0.2 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for AC conditions.
• Leakage Current: Specified leakage current of 1040 µA (after standard application conditions).
• Operating Temperature: Rated for −25°C to +85°C per product specifications.
• Package & Mounting: Snap-in radial can package (φ35 × 30 mm) with tray packing for assembly handling.
• Compliance: RoHS compliant.

Typical Applications

• General Purpose Systems: For general-purpose applications that require a polarized high-voltage capacitor with snap-in mounting and specified ripple endurance.
• High-Voltage Filter Circuits: Suitable where 450 V DC rating and 270 µF capacitance are required to provide bulk energy storage and smoothing under sustained ripple conditions.
• Board-Level Power Modules: Snap-in radial can package and tray packing simplify mechanical retention and assembly for power supply modules within the stated temperature and endurance specifications.

Unique Advantages

• High Voltage Capability: 450 V rating enables use in higher-voltage DC circuits without exceeding the specified voltage limits.
• Defined Ripple Performance: Specified ripple currents at 120 Hz and 50 kHz along with a 3000-hour endurance at 85°C provide predictable behavior under continuous ripple stress.
• Measured Dissipation: tan δ = 0.2 at 20°C, 120 Hz gives a clear loss characteristic for thermal and AC design considerations.
• Compact Snap-In Form Factor: φ35 × 30 mm can with snap-in terminals offers a space-efficient, board-retained solution for power assemblies.
• RoHS Compliant: Meets RoHS directive requirements as specified in the product data.
• Tray Packaging: Tray-packed for organized handling and reduced risk during storage and assembly.
