LGY1H822MELC35

The LGY1H822MELC35 is an aluminum electrolytic capacitor in a snap-in terminal radial can intended for high-reliability power applications. It belongs to Nichicon's LGY long-life series designed for sustained ripple-current operation at elevated temperature.

Targeted use cases include industrial power supplies and ballast applications where long-term stability under ripple current and high ambient temperatures are required. The part is RoHS compliant.

Key Features

• Capacitance & Voltage: 8.2 mF rated at 50 V, with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High-temperature long life: Qualified for 5000 hours of operation with DC bias plus rated ripple current at 105°C.
• Ripple current capability: Rated ripple current of 2.8 A at 120 Hz and 3.22 A at 50 kHz; frequency coefficients apply (e.g., 120 Hz = 1.00, 50 kHz or more = 1.15).
• Temperature range & stability: Operating temperature from −40°C to +105°C; impedance stability values and low-temperature performance are specified in the LGY series data.
• Electrical quality: Dissipation factor (tan δ) for 50 V parts is specified with a maximum of 0.30 at 120 Hz, 20°C; leakage current follows the datasheet formula I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Package & mounting: Radial snap-in can package for secure PCB mounting; package dimensions listed as L: 3.5 × D: 3.5 cm with a seated height maximum of 1.378 inch.
• Polarized device: Polarized aluminum electrolytic capacitor for DC filtering and energy storage applications.
• RoHS compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing where sustained ripple-current handling and 105°C operation are required.
• Ballasts: Designed for ballast circuits that demand reliable long-term operation under ripple conditions.
• General-purpose Power Electronics: Filtering and decoupling in converters and power-conditioning equipment that benefit from a snap-in radial can package.

Unique Advantages

• Long-life specification: 5000-hour endurance at 105°C under rated ripple current provides predictable aging and replacement planning.
• Defined post‑endurance behavior: Endurance limits (capacitance within ±25%, tan δ ≤ 250% of initial, leakage current ≤ initial) give clear criteria for design margining.
• Strong ripple-handling: Explicit ripple-current ratings at both low and high frequencies reduce uncertainty in thermal and lifetime calculations.
• Wide operating range: −40°C to +105°C operation supports a broad set of industrial ambient conditions.
• Robust mounting: Snap-in radial can format enables secure board installation for power modules and high-vibration environments.
• Regulatory compliance: RoHS conformity addresses material restrictions for commercial and industrial projects.
