Overview of LGY1C183MELB30 – Snap-in 105°C Long-Life Aluminum Electrolytic Capacitor, 18,000 µF, 16 V

The LGY1C183MELB30 is an aluminum electrolytic capacitor in a snap-in terminal radial can designed for long-life, high-capacitance power applications. It delivers 18,000 µF at 16 V with ±20% tolerance and is optimized for industrial use where sustained ripple handling and elevated-temperature endurance are required.

Target use cases include industrial power supplies and ballast applications; the part is RoHS compliant, supplied in tray packing, and intended for mass production environments where reliability and high ripple capability matter.

Key Features

  • Construction & Termination — Aluminum electrolytic, snap-in terminal radial can for secure board mounting and rapid assembly.
  • High Capacitance — 18,000 µF nominal capacitance with ±20% tolerance for bulk energy storage and smoothing.
  • Rated Voltage — 16 V DC rating suitable for low-voltage power rails and DC bus applications.
  • High Ripple Current — 3,000 mA at 120 Hz (low frequency) and 3,450 mA at 50 kHz (high frequency), enabling robust performance under heavy AC ripple conditions.
  • Long-Life Endurance — Rated for 5,000 hours at 105°C with defined post-test limits for capacitance change, tan δ and leakage current to ensure predictable long-term behavior.
  • Wide Operating Range — −40°C to 105°C operating temperature range for use across varied industrial environments.
  • Leakage Current — Specified leakage current of 1,600 µA for initial electrical characterization.
  • Package Size & Packing — φ30 × 30 mm can (L: 3 cm × D: 3 cm) supplied in tray packing for production use.
  • Environmental Compliance — Compliant with RoHS directive.

Typical Applications

  • Industrial Power Supplies — Bulk filtering and energy storage for high-reliability industrial converters and power modules.
  • Ballasts — Designed for ballast application where long-life performance at elevated temperatures is required.
  • General-Purpose Power Filtering — Smoothing and decoupling in systems requiring large capacitance and high ripple tolerance.

Unique Advantages

  • Long-term elevated-temperature performance: 5,000-hour endurance at 105°C provides predictable life in high-temperature power systems.
  • High ripple capability: 3.0 A (120 Hz) and 3.45 A (50 kHz) ripple ratings reduce stress and heating in high-current AC environments.
  • Large capacitance in a compact snap-in package: 18,000 µF in a φ30 × 30 mm can supports high energy density while maintaining simple snap-in mounting.
  • Wide operating temperature span: −40°C to 105°C supports use across a broad range of industrial conditions.
  • Production‑ready packaging: Tray packing and mass production status simplify procurement and assembly planning.
  • Regulatory compliance: RoHS conformity supports use in regulated markets.
