Overview of LGY1H392MELA30 – Aluminum Electrolytic Capacitor, Snap-in Terminal

The LGY1H392MELA30 is a Nichicon LGY series aluminum electrolytic capacitor in a snap-in terminal (radial can) package. It delivers 3.9 mF (3900 µF) capacitance at a 50 V rating with a long-life assurance designed for continuous high-temperature operation.

Targeted at industrial power electronics and general-purpose power filtering, this capacitor is specified for 5000 hours of ripple current endurance at 105°C and offers high ripple handling and dependable electrical characteristics for robust supply-filtering and ballast applications.

Key Features

  • Long-life construction — Rated for 5000 hours at 105°C, verified for endurance after DC bias plus rated ripple current applied per series specification.
  • High capacitance — 3.9 mF (3900 µF) with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and smoothing.
  • 50 V rated voltage — Suitable for higher-voltage industrial supply rails and DC bus applications.
  • High ripple current capability — 1.9 A at 120 Hz (low frequency) and 2.185 A at 50 kHz (high frequency) to support heavy ripple and switching environments.
  • Controlled dissipation factor — tanδ = 0.30 (max.) measured at 20°C, 120 Hz for predictable AC loss behavior.
  • Low leakage — Specified leakage current of 1320 µA after rated voltage is applied (per product data).
  • Wide operating temperature range — –40°C to +105°C for use across demanding ambient conditions.
  • Snap-in radial can package — φ25 × 30L (approx. D: 2.5 cm × L: 3.0 cm) with tray packing and mass-production availability for reliable assembly.
  • Environmental compliance — RoHS compliant.
  • Polarized device — Designed for polarized DC applications; follow polarity when installing.

Typical Applications

  • Industrial power supplies — Bulk smoothing and output filtering where long high-temperature life and high ripple handling are required.
  • Lighting ballasts — Energy storage and ripple smoothing in ballast circuitry as indicated for the LGY series.
  • General-purpose power filtering — Decoupling, bulk storage, and ripple reduction in industrial and commercial electronic systems.

Unique Advantages

  • Proven long-life performance — 5000 hours at 105°C provides predictable end-of-life behavior for maintenance planning and reliability engineering.
  • High ripple tolerance — Specified ripple currents at low and high frequencies reduce temperature rise and extend service life in switching and AC-biased circuits.
  • Compact snap-in format — Snap-in radial can (φ25 × 30L) enables secure mechanical mounting and efficient board-level assembly.
  • Wide temperature range — –40°C to +105°C supports deployment across varied industrial environments.
  • Regulatory compliance — RoHS compliance supports environmental and regulatory requirements for modern equipment builds.
  • Production-ready supply — Tray packing and mass production status support volume manufacturing and predictable supply chain integration.
