LGY1K182MELZ35

The LGY1K182MELZ35 is an aluminum electrolytic capacitor from Nichicon’s LGY series featuring a snap-in terminal radial can. It provides 1.8 mF capacitance at an 80 V rating with a polarized design intended for DC power applications.

Designed for industrial power environments, this part is specified for long-life operation—withstanding 5000 hours of ripple-current application at 105°C—and is suited for use in industrial power supplies and ballast applications where reliable power filtering and ripple handling are required. The device is RoHS compliant.

Key Features

• Long-life 105°C endurance — Rated to withstand 5000 hours of ripple-current application at 105°C when subjected to DC bias plus rated ripple current.
• Capacitance and voltage — 1.8 mF nominal capacitance with ±20% tolerance and an 80 V rated voltage for higher-voltage DC circuits.
• Snap-in radial can package — Snap-in terminal mounting (radial, can) for secure PCB installation in power assemblies.
• High ripple-current capability — Rated ripple current of 1.8 A at 120 Hz and 2.07 A at 50 kHz, providing measurable ripple handling across low and high frequencies.
• Wide operating temperature — Specified operating range from −40°C to +105°C for demanding thermal environments.
• Polarized for DC applications — Polarized capacitor suitable for general-purpose DC smoothing and filtering.
• RoHS compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Defined leakage-current specification — Leakage current specified per datasheet formula I ≤ 3√CV (μA) after 5 minutes at 20°C, enabling predictable end-of-life performance planning.
• Compact footprint — Physical dimensions: approximately L: 3.5 × D: 2.2 cm, suited for power modules and assemblies where a snap-in cylindrical can is preferred.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and ripple suppression in high-reliability power supply stages, supported by 5000-hour endurance at 105°C.
• Ballast and Lighting — Specified as suitable for ballast applications where sustained ripple and elevated temperature performance are required.
• High-frequency Power Converters — Ripple-current ratings provided at both 120 Hz and 50 kHz make the part applicable for converters and driver stages with mixed-frequency ripple profiles.
• General-purpose Power Filtering — Polarized snap-in can provides a practical solution for bulk capacitance and DC filtering in industrial assemblies.

Unique Advantages

• Proven long-life specification — 5000 hours at 105°C under rated conditions gives designers a quantifiable endurance metric for lifetime planning.
• Measurable ripple performance — Explicit ripple-current ratings at 120 Hz and 50 kHz allow engineers to size capacitors against real ripple loads.
• Higher-voltage capability — 80 V rating enables use in higher-voltage DC buses where lower-voltage electrolytics are not suitable.
• Broad temperature range — −40°C to +105°C operation supports deployment across a wide range of industrial environments.
• Regulatory compliance — RoHS conformity simplifies environmental compliance for assemblies and end products.
• Predictable leakage behavior — Datasheet leakage-current formula provides a basis for in-circuit leakage budgeting and testing.
