Overview of LLS2A392MELC – 3900 µF, 100 V Snap-In Aluminum Electrolytic Capacitor

The LLS2A392MELC is a snap-in terminal, aluminum electrolytic capacitor in Nichicon's LLS series, offering 3.9 mF nominal capacitance at a 100 V rating. It is designed for general-purpose electronic applications that require high capacitance and high-voltage capability in a radial, snap-in can package.

Key value propositions include robust endurance at elevated temperature (3,000 hours at 85°C), high ripple-current capability at both low and high frequencies, and RoHS compliance for regulatory alignment.

Key Features

  • Capacitance and Tolerance — 3.9 mF (3,900 µF) nominal with ±20% tolerance measured at 120 Hz and 20°C.
  • Voltage Rating — 100 V rated voltage suitable for higher-voltage bulk applications.
  • High Ripple Current Capability — 4,610 mA at 120 Hz (low frequency) and 5,301.5 mA at 50 kHz (high frequency) to support demanding ripple conditions.
  • Endurance and Temperature Range — Qualified for 3,000 hours at 85°C; operating temperature range from –40°C to +85°C.
  • Loss and Leakage — tan δ (dissipation factor) specified at 0.2 (max) at 20°C and 120 Hz; leakage current listed at 1,870 µA.
  • Package and Mounting — Snap-in terminal, radial can (φ35x35L), tray packing for production handling and secure PCB mounting.
  • Environmental Compliance — RoHS compliant.
  • Production Status — Mass production availability.

Typical Applications

  • General-Purpose Electronic Systems — Provides high-capacitance energy storage where a 100 V rating and 3.9 mF are required.
  • High-Voltage Power Supplies — Supports smoothing and bulk capacitance needs in power conversion circuits operating up to 100 V.
  • Power Modules and Industrial Electronics — Designed for systems that demand sustained ripple handling and long-term endurance at elevated temperature.

Unique Advantages

  • High Capacitance at High Voltage: 3.9 mF at 100 V offers substantial stored charge in a compact snap-in can form factor.
  • Designed for Continuous Operation: Endurance rated for 3,000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage after endurance testing.
  • Robust Ripple Performance: High rated ripple currents at both 120 Hz and 50 kHz reduce thermal stress and improve reliability under AC ripple loading.
  • Production-Ready Packaging: Tray packing and mass production status simplify procurement and assembly for volume builds.
  • Regulatory Compatibility: RoHS compliance supports deployments where lead-free materials are required.

Why Choose LLS2A392MELC?

LLS2A392MELC combines high nominal capacitance (3.9 mF) with a 100 V rating in a snap-in aluminum electrolytic package, delivering a balance of energy storage and ripple handling for general-purpose electronic and power applications. Its 3,000-hour endurance at 85°C and specified tan δ and leakage characteristics provide predictable performance over time.

This part is well suited to designs that require high-voltage bulk capacitance with reliable thermal and ripple performance, and for teams seeking a RoHS-compliant, production-ready capacitor option from the Nichicon LLS series.
