LLS2W221MELA

The LLS2W221MELA is an aluminum electrolytic capacitor in Nichicon's LLS series featuring a snap-in terminal configuration. It provides 220 µF capacitance at a 450 V rating with a polarity-marked can package designed for general-purpose power applications.

Engineered for sustained operation, this part delivers rated performance across –25°C to 85°C with an endurance rating of 3000 hours at 85°C, making it suitable for designs that require high-voltage filtering and long-term stability in harsh thermal environments.

Key Features

• High Voltage — Rated at 450 V to support high-voltage smoothing and energy-storage requirements in power assemblies.
• Capacitance and Tolerance — 220 µF with a capacitance tolerance of −20% to +20% at 120 Hz, 20°C for predictable filtering performance.
• Endurance — Designed to withstand 3000 hours of DC bias plus rated ripple current at 85°C, with defined limits for capacitance change, tan δ, and leakage current after testing.
• Ripple Current Capability — Low-frequency ripple current 1.59 A (120 Hz) and high-frequency ripple current 2.274 A (50 kHz) to handle AC ripple across a range of frequencies.
• Dielectric Loss (tan δ) — tan δ specified at 0.20 (measured at 20°C, 120 Hz), enabling evaluation of dissipation for thermal and stability planning.
• Temperature Range — Operating range from –25°C to 85°C, matching the 350–450 V rated-voltage category in the LLS series specifications.
• Snap-In Radial Package — φ25 × 40 mm can with snap-in terminals and provided terminal/PC board hole dimensions for panel or chassis mounting; supplied in tray packing for production handling.
• RoHS Compliant — Conforms to RoHS requirements as indicated for the LLS series.

Typical Applications

• General-purpose power systems — Bulk smoothing and energy storage where 450 V rating and 220 µF capacitance meet high-voltage DC filtering needs.
• Industrial power assemblies — Snap-in mounting and high ripple-current capability support long-duration operation in industrial power supplies and modules.
• High-voltage equipment — Suitable for equipment requiring sustained performance at elevated voltages and temperatures up to 85°C.

Unique Advantages

• High-voltage capability: 450 V rating enables use in circuits that require larger DC bus voltages without series stacking.
• Long endurance: 3000 hours rated at 85°C under DC bias plus rated ripple current provides a predictable life specification for maintenance planning.
• Frequency-flexible ripple handling: Specified ripple currents at both low (120 Hz) and high (50 kHz) frequencies support a range of switching and line-frequency conditions.
• Clear electrical limits: Defined tan δ (0.20) and leakage current (940 µA) figures enable straightforward thermal and leakage budgeting in designs.
• Production-ready packaging: Tray packing and mass-production status simplify procurement and assembly for volume manufacturing.
• Mounting versatility: Snap-in radial can with terminal and PC board hole dimensions provided for secure mechanical retention in assemblies.
