LLS1K392MELB

The LLS1K392MELB is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LLS series. It delivers 3.9 mF capacitance at an 80 V rating with a radial, can-style snap‑in package designed for general-purpose power applications.

Built for sustained ripple loading and long-term operation, this part is specified for 3,000 hours at 85°C, offers low loss (tanδ = 0.2 at 20°C/120 Hz), and is RoHS compliant. It is supplied in tray packing and is in mass production.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 80 V with ±20% tolerance for reliable bulk capacitance in power circuits.
• Snap‑in Terminal Package — Radial, can-style snap‑in mounting for secure board retention and straightforward mechanical installation.
• High Ripple Endurance — Rated low-frequency ripple current of 3.700 A at 120 Hz and high-frequency ripple current of 4.255 A at 50 kHz to support continuous ripple loading.
• Long Life at Elevated Temperature — Specified endurance of 3,000 hours at 85°C under rated ripple and DC bias conditions.
• Loss and Leakage — Low dissipation factor (tanδ = 0.20 at 20°C/120 Hz) and measured leakage current of 1670 µA.
• Operating Range — Rated for operation from −40°C to +85°C to match the LLS series category temperature range.
• Compact Footprint — Size φ30 × 35 mm (L: 3.5 cm × D: 3.0 cm) for high-capacitance density in a modest can package.
• Compliance & Production — RoHS compliant and available in tray packing; part is in mass production.

Typical Applications

• General-purpose power circuits — Bulk energy storage and decoupling where 80 V rating and 3900 µF capacitance are required for smoothing and reservoir functions.
• Power supply filtering — Supports AC ripple handling with specified ripple currents at both low and high frequencies to improve DC bus stability.
• Industrial and commercial equipment — Use where long endurance at elevated temperature (3,000 hours at 85°C) and robust snap‑in mounting are needed for sustained operation.

Unique Advantages

• High-capacitance, high-voltage combination — 3.9 mF at 80 V provides substantial energy storage in a single component, reducing the need for parallel devices.
• Designed for continuous ripple load — Specified ripple current ratings at 120 Hz and 50 kHz enable reliable operation under real-world AC and switching conditions.
• Long endurance rating — 3,000‑hour life at 85°C under rated ripple and DC bias supports longer maintenance intervals and predictable lifecycle planning.
• Low dissipation — Tanδ = 0.20 (20°C/120 Hz) helps minimize heating under AC excitation, assisting thermal management in constrained designs.
• RoHS compliant and production-ready — Environmentally compliant and available in tray packing for streamlined procurement and manufacturing uptake.
