LGY1E223MELB45

The LGY1E223MELB45 is a Nichicon LGY series aluminum electrolytic capacitor in a snap‑in terminal can, offering 22,000 µF capacitance at a 25 V rating. It is built for long‑life, high‑reliability power applications with a 105°C operating upper temperature and a 5000‑hour long life assurance under rated ripple and DC bias.

Designed for industrial power supplies, ballast applications and other general‑purpose power systems, this radial snap‑in package delivers high bulk capacitance, defined ripple handling and temperature endurance in a compact φ30 × 45 mm can suitable for mass production (tray packing).

Key Features

• Capacitance & Voltage — 22,000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Long Life — Rated for operation from −40°C to 105°C with long life assurance of 5000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Ripple handling of 3.5 A at 120 Hz and 4.025 A at 50 kHz, with frequency coefficients provided for higher frequency operation.
• Electrical Characteristics — Leakage current meets I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ for 25 V parts is specified (max. 0.40 at 120 Hz, 20°C).
• Package & Mounting — Radial can with snap‑in terminals (φ30 × 45 mm), suitable for secure snap‑in mounting and tray packing for mass production.
• Reliability & Shelf Life — Endurance criteria: after 5000 hours at 105°C under specified conditions, capacitance change within ±25%, tan δ ≤ 250% of initial spec, leakage ≤ initial spec; shelf life defined after 1000 hours at 105°C with post‑treatment limits.
• RoHS Compliant — Compliant with RoHS directives, marked with white print on a black sleeve.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing where sustained high ripple current and long life at elevated temperature are required.
• Ballast Applications — Specified suitability for ballast use, providing stable capacitance and endurance under continuous operating stress.
• General‑Purpose Power Systems — High‑capacitance support for DC link, filtering and bulk reserve in a variety of general power and control circuits.

Unique Advantages

• High Bulk Capacitance in a Compact Can — 22,000 µF in a φ30 × 45 mm snap‑in package reduces board area compared with multiple smaller capacitors.
• Long Life at Elevated Temperature — Specified 5000 hours endurance at 105°C under rated ripple current and DC bias provides predictable ageing for industrial designs.
• Defined Ripple Capability — Published ripple current values at both low and high frequencies (3.5 A @120 Hz; 4.025 A @50 kHz) let engineers size thermal and cooling requirements accurately.
• Clear Reliability Limits — Endurance and shelf life specifications (capacitance, tan δ, leakage) give measurable pass/fail criteria for long‑term acceptance testing.
• Production‑Friendly Packaging — Snap‑in radial can with tray packing supports high‑volume assembly and reliable board retention during handling.
• Regulatory Compliance — RoHS compliance reduces material‑compliance overhead for regulated product lines.
