LGY1J822MELC45

The LGY1J822MELC45 is an aluminum electrolytic capacitor in a snap-in radial can package, offering 8.2 mF (8200 µF) capacitance at a 63 V rating. It is designed for high-reliability power applications that require large bulk capacitance and robust thermal endurance.

Targeted use cases include industrial power supplies and ballast applications, and other general-purpose power filtering roles where long life, elevated temperature operation and dependable ripple handling are important. Key value propositions are the 105°C continuous category temperature, long-life assurance (5000 hours at 105°C), and snap-in mounting for secure PCB installation in mass-production environments.

Key Features

• Capacitance & Voltage — 8.2 mF (8200 µF) rated at 63 V with ±20% tolerance, delivering substantial bulk storage for DC rails and smoothing tasks.
• Snap-in Radial Can Package — Snap-in terminal type and radial, can-style package (φ35 × 45 mm / L: 4.5 × D: 3.5 cm) for secure mechanical mounting and efficient assembly; supplied in tray packing for mass production.
• High Temperature Long Life — Category temperature range −40°C to +105°C with long-life assurance: rated for 5000 hours of ripple-current operation at 105°C.
• Ripple Current Performance — Rated ripple currents of 3.4 A at 120 Hz and 3.91 A at 50 kHz, suitable for continuous filtering and smoothing under load in power-supply designs.
• Endurance & Stability — Endurance specification: after 5000 hours at 105°C with rated ripple and DC bias, capacitance change remains within ±25% and leakage current meets initial specification limits, supporting predictable long-term behavior.
• Environmental Compliance — RoHS compliant per the product data.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage on high-voltage DC rails where high capacitance and elevated temperature endurance are required.
• Ballasts — Designed and noted for use in ballast applications that demand reliable long-life operation at elevated temperatures.
• General-Purpose Power Filtering — Decoupling, filtering and energy buffering in electronic systems requiring 63 V rated capacitors with large capacitance.

Unique Advantages

• Long-life assurance at 105°C: 5000-hour ripple-current endurance provides predictable performance for designs that operate at elevated temperatures.
• High bulk capacitance at 63 V: 8200 µF reduces the number of parallel components needed to achieve required energy storage and smoothing.
• Robust ripple handling: Specified ripple currents (3.4 A at 120 Hz, 3.91 A at 50 kHz) enable continuous duty filtering in power conversion and supply applications.
• Secure, production-friendly mounting: Snap-in radial can design and tray packing simplify assembly and mechanical retention on power PCBs.
• Wide ambient range: −40°C to +105°C operation supports deployment across varied industrial environments.
• Regulatory compliance: RoHS compliant to support environmental and regulatory requirements in assemblies.
