LLS2W561MELC

The LLS2W561MELC is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LLS series designed for general‑purpose applications. It delivers 560 µF capacitance at a 450 V rating in a radial, can-style snap‑in package (φ35×50 mm) with tray packing and mass production availability.

Engineered for robust power handling, the part combines a 3000‑hour endurance at 85 °C with specified low and high frequency ripple current capability and controlled dissipation factor (tan δ = 0.2 at 20 °C, 120 Hz), supporting designs that require high voltage, high ripple tolerance, and RoHS compliance.

Key Features

• High Voltage Rating — Rated at 450 V to support high‑voltage DC bus requirements within its specified operating range.
• Capacitance & Tolerance — 560 µF with ±20% tolerance (measured at 120 Hz, 20 °C) for predictable bulk capacitance performance.
• Snap‑In Radial Can Package — Snap‑in terminal mounting (radial, can – snap‑in) for secure board installation and mechanical stability.
• Ripple Current Performance — 2880 mA at 120 Hz (low frequency) and 4118.4 mA at 50 kHz (high frequency) to handle significant AC ripple stress.
• Controlled Dissipation Factor — tan δ of 0.2 (max) measured at 20 °C and 120 Hz, aiding in predictable AC loss characteristics.
• Leakage Current Specification — Leakage current specified at 1500 µA for initial electrical characteristics.
• Endurance — Rated for 3000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage after endurance testing.
• Operating Temperature Range — Specified for −25 °C to +85 °C operation (per product specifications for 350–450 V items).
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• General‑Purpose Power Designs — Suited for general‑purpose circuits that require 450 V rated capacitance and substantial ripple current handling.
• High‑Voltage DC Bus Filtering — Provides bulk capacitance and ripple current endurance for designs with elevated DC voltages within the specified rating.
• Long‑Life Power Systems — Applicable where 3000‑hour endurance at 85 °C and stable electrical characteristics over life are required.

Unique Advantages

• High Voltage Capability: 450 V rating allows use in higher DC voltage sections without up‑rating components.
• Strong Ripple Handling: Specified low and high frequency ripple currents (2.88 A @120 Hz, 4.1184 A @50 kHz) reduce thermal stress under ac loading.
• Durability Under Load: 3000 hour endurance at 85 °C with guaranteed limits on capacitance, tan δ, and leakage supports long‑term reliability.
• Secure Snap‑In Mounting: Radial snap‑in can provides stable mechanical attachment for board‑level installations.
• Measured Loss Characteristics: Specified tan δ (0.2 at 20 °C, 120 Hz) for designers needing predictable dissipation behavior.
• Regulatory Compliance: RoHS compliance for use in assemblies requiring restricted substance adherence.
