LLS2W680MELY

The LLS2W680MELY is an aluminum electrolytic capacitor in Nichicon’s LLS series featuring a snap‑in terminal radial can design. It is rated 450 V and 68 µF with polarized construction and is intended for general‑purpose electronic use.

Designed for operation to 85°C and guaranteed to withstand 3000 hours of rated ripple‑current stress at 85°C, this capacitor provides high‑voltage energy storage and ripple handling where snap‑in mounting and long endurance are required. It is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Electrical – High Voltage: Rated voltage of 450 V and capacitance of 68 µF for high‑voltage applications that require substantial energy storage.
• Ripple Current Handling: Specified ripple capabilities of 710 mA at 120 Hz and 1.015 A at 50 kHz, supporting sustained AC stress at the rated voltage.
• Endurance & Reliability: Endurance validated to 3000 hours at 85°C with DC bias plus rated ripple current; capacitance change guaranteed within ±20% after the test.
• Thermal Range: Operating temperature range of −25°C to +85°C for the 350–450 V ratings in the LLS series.
• Mechanical – Snap‑In Mounting: Radial, can‑style snap‑in package for secure PCB insertion and mechanical stability in power assemblies.
• Tolerance & Polarization: Capacitance tolerance of ±20% and polarized construction suitable for typical electrolytic capacitor applications.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental requirements for electronic components.

Typical Applications

• General‑Purpose Power Modules: Bulk energy storage and smoothing in high‑voltage power modules where 450 V rating and high ripple capability are required.
• Industrial Power Electronics: Filtering and ripple suppression in industrial converters and inverters that operate within the −25°C to +85°C temperature range.
• High‑Voltage DC Bus Filtering: Use on DC bus lines to support voltage stabilization and absorb ripple currents consistent with the specified ripple ratings.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use in designs requiring elevated voltage margins without changing component family.
• Proven Endurance: Engineered to withstand 3000 hours of rated ripple current at 85°C, supporting long‑term reliability under continuous stress.
• Effective Ripple Performance: Dual ripple‑current specifications (120 Hz and 50 kHz) provide clear guidance for designs across low and high ripple frequencies.
• Secure Snap‑In Mounting: Radial snap‑in can package simplifies board integration and mechanical retention in power assemblies.
• Regulatory Compliance: RoHS compliant for environmental regulatory alignment in product builds.
