LLS1K392MELA

The LLS1K392MELA is a Nichicon LLS series snap-in aluminum electrolytic capacitor offering 3.9 mF (3900 µF) capacitance at an 80 V rating. Designed as a polarized, snap-in radial can, it delivers bulk capacitance and sustained ripple-handling capability for general-purpose power applications.

With an endurance rating of 3000 hours at 85°C under rated ripple conditions and RoHS compliance, this component targets designers who need reliable long-term performance in designs that require moderate voltage, high ripple current tolerance, and compact board-mounted packaging.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a rated voltage of 80 V and capacitance tolerance of ±20% (–20%~20%).
• Snap-In Radial Package — Can-style, snap-in terminal mounting for secure board installation; packaged in tray packing for handling and assembly.
• Ripple Current Performance — Rated low-frequency ripple current of 3.71 A at 120 Hz and high-frequency ripple current of 4.266 A at 50 kHz, enabling effective ripple filtering under varying frequency conditions.
• Endurance — Designed to withstand 3000 hours at 85°C while subjected to rated DC bias plus rated ripple current, per the LLS series endurance specification.
• Loss & Leakage — Tangent of loss angle (tan δ) of 0.20 measured at 20°C, 120 Hz, and a specified leakage current of 1670 µA.
• Operating Temperature Range — Rated for operation from –40°C to +85°C.
• Mechanical Size — Compact footprint with diameter 25 mm and length 45 mm (L: 4.5 × D: 2.5 cm), suitable for space-conscious designs.
• Compliance & Availability — RoHS compliant and listed as mass production status.

Typical Applications

• General-purpose power circuits — Provides bulk energy storage and smoothing for DC circuits where moderate voltage and significant ripple current capability are required.
• Ripple filtering — Handles rated ripple currents at both 120 Hz and higher-frequency conditions to reduce AC ripple on DC rails.
• Industrial and commercial equipment — Suited for designs that demand long endurance at elevated temperature (3000 h at 85°C) and stable loss characteristics (tan δ = 0.20).

Unique Advantages

• High ripple tolerance: Rated ripple currents of 3.71 A (120 Hz) and 4.266 A (50 kHz) enable reliable ripple absorption across common power frequencies.
• Long-term endurance: Specified endurance of 3000 hours at 85°C under rated conditions supports extended service life in continuous-duty applications.
• Compact snap-in format: Radial can with snap-in terminals simplifies mechanical mounting while conserving board area.
• Predictable electrical characteristics: Specified tan δ and leakage current values support accurate design margining for loss and standby current.
• RoHS compliant and production-ready: Environmentally compliant and available in tray packing for efficient procurement and assembly.
