LLS2D681MELZ

The LLS2D681MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LLS series, specified for general‑purpose power applications. It delivers 680 µF capacitance at a 200 V rating with a compact φ22 × 40 mm can and snap‑in mounting for robust chassis or board installation.

Designed for continuous operation across −40 °C to +85 °C, this part emphasizes durable ripple handling and long endurance — supporting 3,000 hours of rated ripple current at 85 °C — making it suitable where sustained DC bias, high ripple current, and reliable lifetime are required.

Key Features

• Rated Capacitance & Voltage: 680 µF capacitance at 200 V, ±20% tolerance for predictable bulk energy storage and decoupling.
• Snap‑In Radial Package: Snap‑in terminal, radial can (φ22 × 40 mm / L: 4.0 × D: 2.2 cm) for secure mechanical retention and straightforward assembly into power enclosures.
• High Ripple Current Capability: 2.48 A at 120 Hz (low frequency) and 3.72 A at 50 kHz (high frequency) for effective smoothing under both mains and switching conditions.
• Low Dissipation Factor: tan δ = 0.15 (max) at 20 °C, 120 Hz for the 200 V rating, indicating controlled ESR behavior for lower losses.
• Leakage Current: Specified leakage current of 1,100 µA, measured per the product test conditions, supporting predictable start‑up and standby characteristics.
• Endurance: Rated to withstand 3,000 hours at 85 °C with specified limits on capacitance change (±20%), tan δ, and leakage current after test.
• Operating Temperature Range: −40 °C to +85 °C for reliable performance across common industrial and commercial environments.
• Compliance & Supply: RoHS‑compliant construction, tray packing, and listed as in mass production.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in 200 V rails where sustained ripple handling and long endurance at 85 °C are required.
• Power Conversion & Inverters — DC link and filtering applications that benefit from high ripple current capability at both low and high frequencies.
• Uninterruptible Power Systems (UPS) and Power Conditioning — Energy buffering and decoupling where reliable leakage and endurance specifications are important for predictable behavior over time.

Unique Advantages

• High sustained ripple capacity: 2.48 A (120 Hz) and 3.72 A (50 kHz) ratings let designers size fewer capacitors while meeting ripple requirements across switching and mains frequencies.
• Long endurance at elevated temperature: 3,000‑hour endurance at 85 °C provides a clear, verifiable lifetime metric for thermal design and maintenance planning.
• Compact snap‑in format: φ22 × 40 mm can with snap‑in terminals enables secure, repeatable installation in dense power assemblies.
• Measured electrical stability: Specified tan δ (0.15 at 120 Hz, 20 °C) and defined leakage current support predictable loss and start‑up characteristics.
• RoHS compliant and production ready: Environmentally compliant construction and tray packing for streamlined procurement and assembly.
