LGY1K122MELZ30

The LGY1K122MELZ30 is a Nichicon LGY-series aluminum electrolytic capacitor in a snap-in, radial can package optimized for long-life industrial applications. It delivers 1.2 mF capacitance at 80 V with a ±20% tolerance, designed for use where sustained ripple handling and high-temperature endurance are required.

This snap-in terminal capacitor is aimed at industrial power supplies, ballast equipment and general-purpose power filtering where a compact, high-voltage electrolytic with 105°C long-life assurance is needed.

Key Features

• High capacitance and voltage: 1.2 mF (1200 µF) rated at 80 V, providing energy storage and smoothing for higher-voltage power rails.
• Snap-in radial can package: φ22 × 30 mm can with snap-in terminals for secure mounting and efficient insertion into power assemblies.
• 105°C long-life endurance: Rated for 5000 hours at 105°C under DC bias plus rated ripple current to support reliable operation in elevated-temperature environments.
• High ripple current capability: 1.5 A at 120 Hz (low frequency) and 1.725 A at 50 kHz (high frequency) to handle significant AC ripple in power supplies and ballast circuits.
• Wide operating temperature range: −40°C to +105°C for use across a broad range of industrial ambient conditions.
• Controlled leakage and tolerance: Specified leakage current of 920 µA and capacitance tolerance of ±20% for predictable performance in designs.
• Regulatory and production status: RoHS compliant, tray packed, and available in mass production quantities.
• Frequency ripple coefficient: Frequency coefficient data is provided in the LGY series specification (e.g., 1.00 at 120 Hz, up to 1.15 at 1 kHz and above) for accurate ripple-current derating across frequencies.

Typical Applications

• Industrial power supplies: Bulk energy storage and smoothing in high-voltage rails where high ripple current and long life at 105°C are required.
• Lighting ballasts: Durable ripple handling and high-temperature endurance suited to ballast circuits.
• General-purpose power filtering: Decoupling and energy buffering in equipment that requires an 80 V, high-capacitance electrolytic.

Unique Advantages

• Long-life reliability: 5000 hours endurance at 105°C reduces replacement frequency and supports dependable operation in hot environments.
• Robust ripple handling: High specified ripple currents at both low and high frequencies let designers address AC stress across switching and line-frequency applications.
• Compact high-voltage solution: 80 V rating in a φ22 × 30 mm package enables higher-voltage designs without large board area penalties.
• Snap-in mounting: Radial snap-in terminals provide mechanical stability and faster assembly in power modules and chassis-mounted designs.
• Predictable electrical behavior: Specified leakage current and ±20% tolerance support margining and accurate circuit performance modelling.
• Production-ready supply: Tray packing and mass production availability streamline procurement and assembly planning.
