LLS1C333MELC

The LLS1C333MELC is a snap-in aluminum electrolytic capacitor from Nichicon’s LLS series. It delivers 33,000 µF of capacitance at a rated voltage of 16 V in a compact radial snap‑in can designed for general-purpose applications.

Engineered for sustained ripple operation and long-term endurance, the LLS1C333MELC supports continuous operation across –40°C to 85°C and is specified to withstand 3,000 hours of rated ripple current at 85°C, making it suitable for designs that require reliable bulk capacitance and ripple handling.

Key Features

• Core Electrical — 33,000 µF capacitance at 16 V rated voltage with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Ripple Performance — Low-frequency ripple current 5.46 A (120 Hz) and high-frequency ripple current 6.279 A (50 kHz), enabling sustained AC current handling under rated conditions.
• Reliability & Endurance — Specified endurance of 3,000 hours at 85°C with rated ripple current applied; meets LLS series endurance criteria when restored to 20°C after test.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.5 for 16 V parts (measured at 120 Hz, 20°C), supporting predictable dissipation behavior.
• Leakage Current — Typical leakage current listed at 2,170 µA (after five minutes at 20°C under rated voltage conditions).
• Mechanical & Mounting — Snap-in radial can (φ35 × 30 mm length; dimensions L: 30 mm × D: 35 mm) supplied in tray packing for production assembly.
• Environmental Compliance — RoHS compliant; part is in mass production.

Typical Applications

• General-purpose electronics — Suited for designs requiring high bulk capacitance where general-purpose electrolytic capacitors are specified.
• Industrial power systems — Applicable in industrial equipment and assemblies that need sustained ripple current handling at elevated temperatures.
• Commercial electronic equipment — Useful in commercial devices and subsystems that rely on electrolytic bulk capacitance within the stated temperature range.
• Production assemblies — Tray-packed snap-in mounting supports automated insertion and high-volume manufacturing environments.

Unique Advantages

• High capacitance in a compact package — 33,000 µF in a 35 mm can provides significant bulk energy storage without excessive board area.
• Sustained ripple capability — Rated ripple currents at both low and high frequencies (5.46 A at 120 Hz; 6.279 A at 50 kHz) support applications with continuous AC stress.
• Long rated life at elevated temperature — 3,000 hours endurance at 85°C under rated conditions delivers predictable service life for temperature-stressed installations.
• Predictable electrical behavior — Specified tan δ and leakage current enable engineers to estimate loss and leakage for thermal and reliability planning.
• Production-ready packaging — Tray packing and snap-in terminals simplify handling and assembly for medium- to high-volume production.
• Regulatory compliance — RoHS compliance supports use in environmentally regulated product lines.
