Overview of LGY1H182MELZ25 – 50 V Snap‑in Aluminum Electrolytic Capacitor, 1800 µF

The LGY1H182MELZ25 is an aluminum electrolytic capacitor in a snap‑in terminal can, specified for 50 V and 1800 µF (±20%). It is part of Nichicon’s LGY series designed for long‑life operation at elevated temperatures and is offered in tray packing for mass production.

This part targets industrial and general‑purpose power applications where sustained ripple handling and extended endurance at high temperature are required. Key attributes include a 105°C rated operating range, a 5000‑hour endurance rating, and robust ripple current capabilities.

Key Features

  • Capacitance & Tolerance 1800 µF (1.8 mF) with ±20% tolerance, providing a high bulk capacitance for DC filtering and energy storage in 50 V systems.
  • High Voltage Rating Rated voltage 50 V suitable for medium‑voltage power rails and power supply designs.
  • Long‑life Endurance 5000 hours life at 105°C when subjected to rated DC bias plus rated ripple current, supporting sustained high‑temperature operation.
  • Ripple Current Capability 1300 mA at 120 Hz (low frequency) and 1495 mA at 50 kHz (high frequency), enabling handling of significant AC ripple stress.
  • Low Leakage Specified leakage current of 900 µA, consistent with reliable low‑current performance after voltage application.
  • Loss Tangent tan δ (DF) = 0.30 measured at 20°C and 120 Hz for the 50 V rating, indicating the dielectric loss characteristic for this voltage class.
  • Robust Temperature Range Operating from −40°C to +105°C, suitable for elevated‑temperature industrial environments.
  • Form Factor & Mounting Compact radial snap‑in can, dimension φ22 × 25 mm (L: 2.5 × D: 2.2 cm), designed for secure board mounting in power assemblies.
  • Compliance & Production RoHS‑compliant; supplied in tray packing and available in mass production quantities.

Typical Applications

  • Industrial Power Supplies Suited for industrial power supply designs where long life and dependable performance at 105°C are important.
  • Ballast Applications Designed for ballast circuits as indicated by the LGY series specification for long‑life operation.
  • General‑Purpose Power Systems For general‑purpose electronic equipment requiring a 50 V, high‑capacitance snap‑in electrolytic capacitor.

Unique Advantages

  • Extended High‑Temperature Reliability: 5000‑hour endurance at 105°C provides predictability for designs exposed to continuous elevated temperatures.
  • High Ripple Handling: Rated for 1.3 A (120 Hz) and 1.495 A (50 kHz) ripple current, supporting applications with substantial AC ripple demands.
  • Compact Snap‑in Package: φ22 × 25 mm snap‑in can delivers high capacitance in a small footprint for space‑constrained power modules.
  • Controlled Dielectric Loss: tan δ = 0.30 at 20°C/120 Hz for the 50 V rating, allowing designers to account for dissipation in thermal and reliability budgets.
  • Low Leakage Current: 900 µA maximum leakage provides stable performance after voltage application, useful for power management and standby conditions.
  • Production‑Ready Supply: RoHS compliance, tray packing, and mass production status simplify procurement and manufacturing integration.
