Overview of LLS1K392MELZ – Aluminum Electrolytic Capacitor, Snap-In, 80 V, 3,900 µF

The LLS1K392MELZ is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose electronic applications. It provides 3.9 mF (3,900 µF) of capacitance at an 80 V rating in a radial can snap-in package, delivering high ripple-current capability and long endurance for sustained operation.

Engineered for reliable bulk energy storage and filtering, the part offers a balance of capacitance, voltage rating and lifecycle performance, with RoHS compliance and mass-production availability for volume designs.

Key Features

  • Capacitance & Voltage: 3.9 mF (3,900 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance.
  • Snap-In Package: Radial, can-type snap-in terminal mounting for secure board retention and straightforward assembly; supplied in tray packing for production handling.
  • Ripple Current Performance: Rated ripple current of 3,620 mA at 120 Hz (low frequency) and 4,163 mA at 50 kHz (high frequency), enabling effective filtering under AC ripple conditions.
  • Electrical Losses: tan δ (DF) ≤ 0.20 measured at 20°C and 120 Hz, supporting predictable AC behavior in designs.
  • Leakage Current: Specified leakage current of 1,670 µA.
  • Endurance: 3,000 hours life at 85°C under rated conditions, with defined limits on capacitance change, tan δ and leakage after endurance testing.
  • Temperature Range: Rated for operation from −40°C to +85°C.
  • Compliance & Availability: RoHS compliant and available in mass production from Nichicon.

Typical Applications

  • General Purpose Electronics: Bulk energy storage and smoothing in general-purpose circuits where 80 V rating and high capacitance are required.
  • Power Filtering: AC ripple absorption and smoothing duties that benefit from the capacitor’s specified ripple-current ratings and low tan δ.
  • Industrial Equipment: Designs requiring durable electrolytic capacitance with a 3,000-hour endurance at 85°C and a −40°C lower operating limit.

Unique Advantages

  • High Bulk Capacitance at Elevated Voltage: 3.9 mF at 80 V provides significant energy storage in a compact snap-in can for higher-voltage applications.
  • Robust Ripple Handling: High rated ripple currents at both low and high frequencies reduce heating and improve lifetime in ripple-intensive environments.
  • Defined Endurance: 3,000-hour rating at 85°C gives predictable service life parameters for planning maintenance and product lifecycles.
  • Stable Loss Characteristics: Specified tan δ (≤ 0.20 at 20°C, 120 Hz) supports consistent AC performance and design predictability.
  • RoHS-Compliant Production: Environmentally compliant manufacturing and tray packing suitable for volume assembly operations.

Why Choose LLS1K392MELZ?

LLS1K392MELZ is positioned for designs that require substantial bulk capacitance at an 80 V rating with dependable ripple-current capability and validated endurance. Its snap-in, radial can construction and tray packing support efficient assembly in production environments, while Nichicon’s LLS series specifications provide clear performance limits for engineering validation.

This capacitor is well suited to engineers and procurement teams building general-purpose power and industrial electronics where long-term consistency, RoHS compliance and mass-production availability are important.
