LGY1C822MELZ30

The LGY1C822MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGY series, designed for long-life operation in demanding power environments. It delivers 8.2 mF capacitance at a 16 V rating, polarized construction, and a rugged radial can snap-in package for secure board mounting.

Engineered for industrial power supplies and ballast applications, this part emphasizes dependable ripple handling and thermal endurance—rated for continuous operation up to 105°C with a 5000-hour ripple endurance specification. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 8.2 mF capacitance rated at 16 V with ±20% tolerance, suitable for bulk energy storage and smoothing in low-voltage power sections.
• Long-life Endurance — Designed to withstand 5000 hours of DC bias plus rated ripple current at 105°C; after endurance testing capacitance remains within ±25% of initial value and leakage current stays at or below initial specified limits.
• High Operating Temperature — Rated for –40°C to +105°C operation for stable performance across industrial temperature ranges.
• Ripple Current Capability — Rated ripple current of 2 A at 120 Hz and 2.3 A at 50 kHz, enabling effective ripple absorption in power supply outputs and converters.
• Package & Mounting — Radial can, snap-in terminal type for secure mechanical mounting in power assemblies and ease of board insertion.
• Leakage Current Specification — Series leakage current follows I ≤ 3√CV (μA) after 5 minutes at 20°C, providing predictable leakage behavior for design margin calculations.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and output smoothing where long-term ripple endurance at elevated temperature is required.
• Ballasts — Energy buffering and ripple handling in ballast circuits where robust high-temperature operation is essential.
• General Purpose Power Filtering — Decoupling and smoothing tasks in electronic systems that need polarized capacitors with snap-in mounting.

Unique Advantages

• Long Thermal Endurance: 5000-hour rating at 105°C provides predictable life performance for high-temperature installations.
• Measured Ripple Ratings: Specified ripple currents at 120 Hz and 50 kHz (2 A and 2.3 A respectively) let designers size components against real ripple loads.
• Reliable Mounting: Snap-in radial can package ensures solid mechanical retention in power modules and assemblies.
• Predictable Electrical Behavior: Leakage current specified by I ≤ 3√CV and defined tan δ limits (tan δ ≤ 0.50 at 16 V) support conservative margining in designs.
• Wide Operating Range: –40°C to +105°C rating supports a broad set of industrial environments.
