LLS2Z391MELZ

The LLS2Z391MELZ from Nichicon is an aluminum electrolytic capacitor in the LLS series, offered in a snap‑in terminal radial can. It is a standard 85°C part rated at 390 µF and 180 V with polarized construction for general‑purpose circuits.

Designed for applications requiring sustained ripple endurance, this part is specified to withstand 3000 hours of rated ripple current at 85°C and is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Electrical: 390 µF capacitance at 180 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• Ripple Current Capability: Rated ripple current 1.84 A at 120 Hz and 2.76 A at 50 kHz; endurance validated for 3000 hours at 85°C under rated ripple conditions.
• Temperature Range: Operating temperature from −40°C to +85°C.
• Reliability / Endurance: Meets endurance criteria after 3000 hours at 85°C (capacitance within ±20%, tan δ and leakage current within specified limits per the LLS series datasheet).
• Mechanical / Mounting: Snap‑in terminal radial can package; size L: 2.5 × D: 2.2 cm with a seated height of 2.5 cm.
• Polarization: Polarized aluminum electrolytic construction for DC applications.
• Regulatory: RoHS compliant to EU directives listed in the product description.

Typical Applications

• General Purpose – Intended for general‑purpose electronic circuits that require 390 µF at 180 V in a snap‑in radial can format.
• Environments with sustained ripple – Suitable where components must withstand rated ripple current for extended periods at elevated temperature (3000 hours at 85°C).
• Board‑mounted power assemblies – Snap‑in radial package supports secure mounting in assemblies where the stated dimensions (L: 2.5 × D: 2.2 cm) and terminal style are appropriate.

Unique Advantages

• Proven ripple endurance: Specified to withstand 3000 hours of rated ripple current at 85°C, providing predictable long‑term performance in ripple‑exposed circuits.
• Clear electrical specification: 390 µF at 180 V with defined ripple current values (1.84 A at 120 Hz; 2.76 A at 50 kHz) for straightforward selection and design margining.
• Wide operating temperature: −40°C to +85°C rating supports operation across common ambient ranges for industrial and commercial electronics.
• Secure snap‑in mounting: Radial, snap‑in can package enables robust board retention for panel and chassis‑mounted power modules.
• Regulatory compliance: RoHS compliance aligns with lead‑free and restricted substances requirements.
