LLS2V681MELB

The LLS2V681MELB is an aluminum electrolytic capacitor in a snap‑in terminal radial can package, offering 680 µF capacitance at a 350 V rating with ±20% tolerance. It is built for general‑purpose applications requiring high‑voltage capacitance and robust ripple handling.

Key product attributes include a low loss tangent (tanδ = 0.15 at 120 Hz, 20°C), rated endurance of 3000 hours at 85°C under rated ripple conditions, and RoHS compliance—making it suitable for long‑life power applications where reliability and defined electrical performance are required.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance rated for 350 V DC, providing substantial energy storage per component for high‑voltage circuits.
• Tolerance & Loss: ±20% capacitance tolerance and a maximum tanδ of 0.15 (measured at 120 Hz, 20°C), enabling predictable AC loss performance in design calculations.
• Endurance at Elevated Temperature: Specified to withstand 3000 hours at 85°C with rated ripple current applied, meeting defined long‑term stability requirements after endurance testing.
• Ripple Current Capability: Rated ripple current of 3.15 A at 120 Hz and 4.505 A at 50 kHz, supporting effective ripple smoothing in power systems within specified frequency bands.
• Operating Temperature Range: −25°C to +85°C, suitable for systems that operate within this ambient range.
• Package & Mounting: Radial can with snap‑in terminals (φ30 × 50L physical footprint), designed for secure chassis or module mounting and straightforward assembly into power racks or boards.
• Leakage Current Specification: Leakage current limited to I ≤ 3√(C·V) μA after 5 minutes at 20°C (per datasheet formula), allowing predictable standby current behavior.
• RoHS Compliant: Meets RoHS directive requirements as stated in the product datasheet.

Typical Applications

• General‑purpose power filtering: Bulk smoothing and ripple reduction in high‑voltage power modules where a 350 V, 680 µF capacitor is required.
• Energy storage for DC systems: Local energy buffering in DC link or intermediate circuits within the stated temperature and ripple current limits.
• Industrial power equipment: Use in equipment and assemblies that demand defined endurance at elevated temperature (3000 h at 85°C) and predictable loss characteristics.

Unique Advantages

• High‑voltage capability: 350 V rating enables use in higher‑voltage DC systems without stacking multiple lower‑voltage parts.
• Long defined life: 3000 hours endurance at 85°C under rated conditions provides a quantifiable reliability baseline for design validation.
• Controlled AC loss: tanδ = 0.15 (max) at 120 Hz supports thermal and efficiency calculations for AC ripple environments.
• Robust ripple handling: Specified ripple current values at 120 Hz and 50 kHz allow designers to size the capacitor for specific frequency components of ripple.
• Snap‑in radial package: Mechanical mounting designed for secure installation and straightforward assembly into power modules or chassis.
• Predictable leakage behavior: Leakage current defined by the datasheet formula (I ≤ 3√CV μA) aids in power budgeting and quiescent current estimates.
