Overview of LGU1V392MELZ – Aluminum Electrolytic Capacitor, Snap‑in, 35 V, 3900 µF

The LGU1V392MELZ from Nichicon is a snap‑in terminal aluminum electrolytic capacitor rated 35 V with 3,900 µF capacitance and ±20% tolerance. Designed for general‑purpose power applications, it provides bulk energy storage and smoothing in assemblies that require robust ripple handling and extended endurance.

Key value comes from high ripple current capability and long endurance at elevated temperature: specified for operation from −40°C to +105°C with 3,000 hours life at 105°C. The part is RoHS compliant and available in tray packing for mass production use.

Key Features

  • Capacitance & Voltage — 3.9 mF (3,900 µF) nominal capacitance at a rated voltage of 35 V with ±20% tolerance.
  • High Ripple Current — 1,690 mA rated at 120 Hz and 1,943.5 mA rated at 50 kHz to support demanding AC ripple on power rails.
  • Temperature & Endurance — Operating range −40°C to +105°C with 3,000 hours endurance at 105°C under rated ripple and DC bias.
  • Electrical Losses — Tangent of loss angle (tan δ) specified at 0.35 max (measured at 20°C, 120 Hz), aiding predictable performance in filter designs.
  • Leakage Current — Initial leakage current specified at 1,100 µA for controlled standby and charge‑holding behavior.
  • Package & Mounting — Radial can with snap‑in terminals; compact form factor φ22 × 30 mm length suitable for board‑level insertion and through‑hole assembly.
  • Compliance & Availability — RoHS compliant and available in tray packing for mass production volumes.

Typical Applications

  • Power supply smoothing — Bulk filtering and decoupling on 35 V rails where sustained ripple current and elevated temperature endurance are required.
  • DC bus stabilization — Energy storage for converters and regulators that need reliable capacitance under DC bias and ripple load.
  • General purpose industrial electronics — Use in systems requiring long life at high ambient temperatures and robust ripple tolerance.

Unique Advantages

  • Long high‑temperature endurance: 3,000 hours at 105°C provides predictable life for designs exposed to elevated operating temperatures.
  • High ripple capability: Separate low‑ and high‑frequency ripple current ratings (1.69 A at 120 Hz, 1.944 A at 50 kHz) help minimize heating and extend service life when subjected to AC ripple.
  • Compact snap‑in package: φ22 × 30 mm can with snap‑in terminals simplifies mechanical mounting and board layout for through‑hole assemblies.
  • Controlled electrical characteristics: Specified tan δ and leakage current values support predictable behavior in filter and energy‑storage applications.
  • Production ready: Tray packing and mass production status streamline procurement and assembly for volume manufacturing.

Why Choose LGU1V392MELZ?

LGU1V392MELZ balances high capacitance and ripple handling in a compact snap‑in package, making it suitable for general‑purpose power designs that must operate reliably up to +105°C. Its specified tan δ, leakage current, and long endurance at elevated temperature allow engineers to design with clear, verifiable performance targets.

This part is aimed at customers building power supplies, DC bus systems, and industrial electronics that need robust bulk capacitance, predictable thermal performance, and production‑ready packaging backed by Nichicon's LGU series specifications.
