Overview of LLS1J392MELA – Snap-in 85°C Aluminum Electrolytic Capacitor

The LLS1J392MELA is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLS series, offering 3.9 mF (3900 µF) capacitance at a 63 V rating. Designed as a general-purpose board-level component, it combines high capacitance with a snap-in radial can package for secure mounting and straightforward assembly in mass-production environments.

Key value comes from its electrical endurance and ripple handling: a 3000-hour endurance at 85°C, specified low- and high-frequency ripple current ratings, measurable tanδ, and defined leakage current—making it suitable where sustained bulk capacitance and reliable ripple performance are required.

Key Features

  • Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 63 V rated voltage and ±20% tolerance for general-purpose bulk energy storage.
  • Snap-in Radial Can Package — Snap-in terminal, radial can construction provides robust board retention and is supplied in tray packing for production handling.
  • Endurance at Elevated Temperature — Rated for 3000 hours at 85°C under rated ripple current conditions, meeting the LLS series endurance specification for sustained operation.
  • Ripple Current Capability — Low-frequency ripple current of 3.13 A at 120 Hz and high-frequency ripple current of 3.599 A at 50 kHz, enabling effective filtering under varying frequency conditions.
  • Electrical Loss and Leakage — Specified tanδ of 0.25 (max.) at 20°C and 120 Hz and a leakage current of 1480 µA, allowing predictable loss and leakage behavior for circuit design.
  • Operating Temperature Range — Rated for −40°C to +85°C operation, suitable for a wide ambient temperature range within the LLS series limits.
  • Compliance & Production — RoHS compliant and listed as mass production status; supplied in tray packing for manufacturing scale.
  • Physical Dimensions — Can dimensions φ25 × 35L (L: 3.5 cm × D: 2.5 cm) for compact board-level placement.

Typical Applications

  • General-purpose electronic equipment — Provides bulk capacitance for smoothing and decoupling in a broad range of electronic systems where a 63 V, 3.9 mF capacitor is required.
  • Board-level power supplies and converters — Used for ripple absorption and energy storage where rated ripple current (3.13 A at 120 Hz / 3.599 A at 50 kHz) and 85°C endurance are needed.
  • Industrial control modules — Suited for general-purpose power filtering in industrial electronics that operate within −40°C to +85°C and require long-term capacitor endurance.
  • Mass-production assemblies — Tray-packed, snap-in format simplifies placement and assembly for production runs requiring consistent component handling and reliability.

Unique Advantages

  • Durable high-temperature endurance — 3000 hours at 85°C under rated ripple current provides predictable life performance for designs constrained by elevated operating temperature.
  • Measurable ripple performance — Dual ripple current specifications at 120 Hz and 50 kHz let designers quantify filtering capability across common frequency ranges.
  • Practical, production-ready package — Snap-in radial can and tray packing support efficient assembly and secure mechanical retention on PCBs.
  • Clear electrical parameters — Specified tanδ and leakage current values (0.25 at 20°C/120 Hz; 1480 µA) support accurate thermal and power-loss budgeting in circuits.
  • RoHS compliant — Meets RoHS directive requirements for restricted substances, supporting regulatory compliance in product builds.
  • Polarized, high-capacitance solution — High nominal capacitance (3.9 mF) in a compact form factor for designs that require polarized bulk storage at up to 63 V.

Why Choose LLS1J392MELA?

LLS1J392MELA positions itself as a reliable, production-oriented aluminum electrolytic solution for designers who need substantial bulk capacitance in a snap-in radial package. With explicit ripple current ratings at both low and high frequencies, defined tanδ and leakage figures, and a 3000-hour endurance at 85°C, this part provides quantifiable electrical and thermal characteristics for robust system design.

This capacitor is well suited to engineers and procurement teams specifying general-purpose power smoothing and energy-storage components for medium-voltage board-level applications that require RoHS compliance, repeatable assembly handling, and documented long-term endurance.
