LLS2A392MELB

The LLS2A392MELB is a Nichicon LLS series aluminum electrolytic capacitor in a snap-in terminal can, rated 100 V with 3.9 mF (3900 µF) nominal capacitance and ±20% tolerance. It is an 85°C standard device designed for general-purpose applications that require bulk capacitance and robust ripple-current handling.

Key value propositions include high ripple-current capability at both low and high frequencies, a 3000-hour endurance at 85°C, and a compact snap-in radial can package (φ30 × 45 mm) suitable for medium- to high-power assemblies manufactured at scale.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap-in Radial Package — Snap-in terminal type in a radial can package for secure panel or chassis mounting; size φ30 × 45 mm (L: 4.5 × D: 3.0 cm).
• High Ripple Current Capacity — Rated ripple current of 4.67 A at 120 Hz (low frequency) and 5.37 A at 50 kHz (high frequency), supporting applications with significant AC ripple.
• Endurance at Elevated Temperature — Qualified for 3000 hours of operation at 85°C under rated ripple current conditions as specified for the LLS series.
• Leakage and Dissipation — Leakage current listed at 1870 µA and tan δ (DF) of 0.2 maximum at 20°C and 120 Hz for the 100 V rating, enabling predictable loss and leakage behavior.
• Polarized Design — Polarized aluminum electrolytic construction for bulk- capacitance roles where polarity is observed.
• Manufacturing & Compliance — Tray packing and mass production status with RoHS compliance.

Typical Applications

• Power supply filtering — Bulk capacitance and specified ripple-current handling make this capacitor suitable for smoothing and filtering in general-purpose power supply circuits.
• Bulk decoupling — Provides energy storage for decoupling in electronic assemblies that require large capacitance at up to 100 V.
• Industrial and commercial equipment — Snap-in mounting and 85°C endurance support use in medium-duty industrial or commercial systems where reliable long-term operation is required.

Unique Advantages

• High-voltage capability: 100 V rating allows use in higher-voltage general-purpose circuits where large capacitance is needed.
• Robust ripple tolerance: Defined ripple-current ratings at both low and high frequencies (4.67 A @120 Hz; 5.37 A @50 kHz) reduce thermal stress in ripple-heavy applications.
• Extended endurance: 3000 hours at 85°C under rated conditions provides predictable lifetime performance for sustained operation.
• Compact snap-in form factor: Radial, snap-in can (φ30 × 45 mm) enables secure mechanical mounting and straightforward assembly into chassis or modules.
• Measured loss and leakage characteristics: Specified tan δ (0.2 max at 20°C/120 Hz) and listed leakage current allow designers to size losses and standby currents accurately.
• Production-ready and compliant: Tray packing and mass-production status plus RoHS compliance simplify procurement and environmental compliance workflows.
