Overview of LGY2A392MELC45 – 3900 µF, 100 V Snap‑in Aluminum Electrolytic Capacitor

The LGY2A392MELC45 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGY series, offering 3.9 mF capacitance at 100 V with ±20% tolerance. Designed for long life and industrial usage, it delivers high ripple handling and stable performance across a wide temperature range.

With a 5000-hour endurance rating at 105°C and RoHS compliance, this radial can (φ35 × 45 mm) in tray packing is targeted at general-purpose and industrial power applications where dependable filtering and energy storage are required.

Key Features

  • Capacitance and Voltage: 3.9 mF (3900 µF) rated at 100 V with ±20% tolerance for bulk filtering and energy storage in high-voltage rails.
  • Long Life Endurance: 5000 hours rated life at 105°C under rated ripple current, supporting continuous operation in demanding environments.
  • High Ripple Current Capability: 2.900 A at 120 Hz (low frequency) and 3.335 A at 50 kHz (high frequency), enabling effective smoothing of both low‑ and high‑frequency ripple currents.
  • Controlled Dissipation Factor: tan δ = 0.20 (max) at 20°C, 120 Hz for the 80·100 V range, indicating predictable AC loss characteristics.
  • Leakage Current: Specified leakage current of 1870 µA, providing measurable DC leakage performance for design verification.
  • Temperature Range: Operates from –40°C to +105°C to accommodate a broad range of industrial ambient conditions.
  • Package & Mounting: Snap‑in radial can, size φ35 × 45 mm, supplied in tray packing for reliable PCB mounting and production handling.
  • Regulatory: Compliant with RoHS requirements.

Typical Applications

  • Industrial power supplies: Bulk filtering and smoothing where long‑life and sustained ripple performance at elevated temperature are required.
  • Ballast applications: Energy storage and ripple suppression in ballast circuits as noted for the LGY series.
  • General‑purpose power filtering: Use in a variety of electronic equipment that requires high capacitance, high‑voltage filtering and stable long‑term performance.

Unique Advantages

  • Long‑life reliability: 5000‑hour rating at 105°C reduces replacement cycles and supports continuous operation in industrial assemblies.
  • High ripple handling: Specified ripple currents at both 120 Hz and 50 kHz help minimize temperature rise and extend service life in real-world power applications.
  • Wide operating temperature: –40°C to +105°C supports deployments across a broad range of ambient conditions without derating design choices.
  • High voltage capability: 100 V rating enables use on higher DC bus voltages where lower‑voltage devices would be unsuitable.
  • Production‑ready packaging: Tray packing and mass production status simplify procurement and assembly for volume manufacturing.
  • Regulatory compliance: RoHS compliance facilitates use in regions and products with environmental restrictions.
