LGY2A122MELA35

The LGY2A122MELA35 is a Nichicon LGY-series snap-in aluminum electrolytic capacitor specified for high-voltage, long-life applications. It pairs a 100 V rated voltage with 1200 µF capacitance and snap-in radial can mounting to support robust power-electronics assemblies.

Designed for industrial power supplies, ballast applications and other general-purpose uses, this part delivers long endurance at elevated temperature and strong ripple-current capability to support dependable DC filtering and energy storage in demanding environments.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance at a 100 V rated voltage with ±20% tolerance for bulk energy storage and high-voltage DC filtering.
• High-Temperature Long Life — Rated for operation from −40°C to 105°C with endurance specified at 5000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Supports 1600 mA at 120 Hz (low frequency) and 1840 mA at 50 kHz (high frequency); frequency coefficients for rated ripple current are provided across 50 Hz–50 kHz and above.
• Electrical Losses — Low dissipation factor with tan δ ≤ 0.20 measured at 20°C, 120 Hz for the 100 V rating, enabling efficient operation in power circuits.
• Leakage Current — Specified leakage current of 1030 µA as provided in the product data.
• Packaging & Mounting — Snap-in radial can (φ25 × 35 mm length) packaged in trays for production assembly and secure PCB retention.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and filtering where sustained ripple current and long life at 105°C are required.
• Ballast Applications — Specified suitability for ballast use as noted in the LGY series datasheet, leveraging the high-voltage rating and endurance.
• General-Purpose Power Electronics — Energy storage and decoupling in equipment requiring a 100 V-rated, long-life electrolytic capacitor.

Unique Advantages

• Long Endurance at Elevated Temperature — 5000 hours rated life at 105°C provides predictable performance and service life for high-temperature installations.
• High Voltage Capability — 100 V rating enables use in higher-voltage DC rails without series stacking.
• Robust Ripple Handling — High ripple-current ratings at both low and high frequencies reduce thermal stress and support reliable filtering under real-world load conditions.
• Secure Snap-In Mount — Radial snap-in can design allows firm mechanical retention on PCBs for production environments.
• Low Losses — tan δ of 0.20 (120 Hz, 20°C) helps maintain efficiency in power-conversion circuits.
• Production-Ready Packaging — Tray packing and mass production status support volume assembly and procurement planning.
