LLS2Z471MELZ

The LLS2Z471MELZ is a Nichicon LLS series snap-in aluminum electrolytic capacitor offering 470 µF capacitance at a 180 V rating. It is a radial, snap-in can designed for general-purpose power applications where high ripple handling and long endurance are required.

Key value comes from its 3000-hour endurance at 85°C under rated ripple current, robust ripple current specifications across low and high frequencies, and compact φ22 × 30 L package in tray packing for production environments.

Key Features

• Capacitance & Tolerance — 470 µF with a capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 180 V rated voltage for higher-voltage filtering and energy storage needs.
• Ripple Current Capability — Low-frequency ripple current of 1.91 A at 120 Hz and high-frequency ripple current of 2.865 A at 50 kHz, enabling reliable performance across switching and line-frequency conditions.
• Endurance — Specified to withstand 3000 hours with rated ripple current at 85°C, maintaining capacitance and leakage within the datasheet limits.
• Low Loss — tan δ (loss tangent) 0.15 measured at 20°C, 120 Hz, supporting efficient AC performance.
• Leakage Current — Typical leakage current listed as 870 µA.
• Operating Temperature — Rated for −40°C to +85°C operation.
• Package & Mounting — Snap-in radial can, dimensions φ22 × 30 L, supplied in tray packing for handling and automated assembly workflows.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Effective for bulk and smoothing capacitors in power supplies and converters where 180 V rating and high ripple handling are needed.
• Industrial Power Electronics — Suited for industrial control and drive systems that require durable capacitors with long endurance at elevated temperatures.
• Switching Power Converters — Supports both low- and high-frequency ripple currents encountered in switching regulator outputs and DC link circuits.

Unique Advantages

• Proven Endurance: 3000-hour rating at 85°C under rated ripple current provides predictable long-term performance in demanding thermal environments.
• Wide Ripple Bandwidth: Distinct low- and high-frequency ripple current ratings (1.91 A at 120 Hz and 2.865 A at 50 kHz) cover common power-conversion scenarios.
• High Voltage Capability: 180 V rating enables use in higher-voltage rails without up-rating component stacks.
• Compact Snap-In Package: φ22 × 30 L radial snap-in can in tray packing supports streamlined assembly and robust mechanical mounting.
• Low Dissipation: tan δ = 0.15 at 120 Hz (20°C) indicates controlled dielectric loss for efficient operation.
• Regulatory Compliance: RoHS compliance simplifies integration into designs targeting restricted-substance requirements.
