LGY1E223MELC35

The LGY1E223MELC35 is an aluminum electrolytic capacitor in a snap-in terminal can, designed for long-life, high-reliability power applications. It delivers 22 mF capacitance at a 25 V rating and is optimized for industrial power supplies and ballast applications where sustained ripple handling and extended thermal endurance are critical.

Part of Nichicon's LGY long-life series, this radial snap-in capacitor is RoHS compliant and specified for continuous operation from −40°C to 105°C with a guaranteed life of 5000 hours at 105°C under rated ripple and DC bias conditions.

Key Features

• Capacitance & Voltage: 22 mF nominal capacitance with a 25 V rated voltage and tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• High-Temperature Long Life: Rated for 5000 hours at 105°C when subjected to DC bias plus rated ripple current; endurance limits specify capacitance change within ±25% and leakage current ≤ initial specified value after the test.
• Robust Ripple Handling: Rated ripple current of 3.5 A at 120 Hz and 4.025 A at 50 kHz, with the LGY series frequency coefficient showing 1.00 at 120 Hz and 1.15 at 50 kHz and above.
• Thermal Range & Stability: Operating temperature range from −40°C to +105°C; impedance stability specified with Z(−25°C)/Z(+20°C) up to 4 and Z(−40°C)/Z(+20°C) up to 20 for the 16–100 V range.
• Leakage and Loss Characteristics: Leakage current specified by I ≤ 3√CV (μA) after 5 minutes at 20°C; tangent of loss angle (tan δ) for 25 V is specified with a maximum of 0.40.
• Package & Mounting: Radial, snap-in can package (L: 3.5 × D: 3.5 cm) designed for secure snap-in board mounting; polarized construction.
• Regulatory Compliance: Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing where long-term ripple handling and high-temperature endurance are required.
• Ballast Applications: Designed specifically for ballast use cases that demand stable capacitance and reliable ripple performance at elevated temperatures.
• General-Purpose Power Systems: General-purpose power filtering and decoupling in equipment requiring a robust, polarized snap-in capacitor.

Unique Advantages

• Extended High-Temperature Endurance: 5000-hour life rating at 105°C provides predictable aging and performance for designs exposed to sustained thermal stress.
• Reliable Ripple Capacity: High rated ripple currents at both low and high frequencies (3.5 A at 120 Hz; 4.025 A at 50 kHz) help maintain voltage stability in demanding power circuits.
• Measurable Stability Metrics: Clear specifications for impedance vs. temperature, tan δ, and leakage current allow straightforward thermal and reliability margining in designs.
• Snap-In Packaging for Secure Mounting: Radial snap-in can simplifies board installation and mechanical retention for high-vibration industrial environments.
• RoHS Compliance: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for restricted substances, facilitating use in regulated markets.
