LGU2E221MELZ

The LGU2E221MELZ is a snap‑in, radial can aluminum electrolytic capacitor delivering 220 µF at a rated voltage of 250 V. Designed for general‑purpose power applications, it combines high ripple handling with long endurance at elevated temperature.

Featuring a -40°C to 105°C operating range and a rated life of 3000 hours at 105°C under rated ripple conditions, this RoHS‑compliant part is supplied in tray packing for production assembly.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 250 V and a tolerance of ±20%.
• High‑temperature Endurance — Specified for 3000 hours at 105°C with rated ripple current applied; meets the LGU series endurance criteria when restored to 20°C after test.
• Ripple Current Performance — Low frequency ripple handling of 1.0 A at 120 Hz and high frequency ripple handling of 1.5 A at 50 kHz as specified for this part.
• Loss and Leakage — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz, and specified leakage current of 700 µA.
• Temperature Range — Operating temperature from −40°C to +105°C for use across a wide range of environments.
• Mechanical & Mounting — Snap‑in radial can package, size φ22 × 25L (L: 2.5 cm × D: 2.2 cm), designed for secure panel or chassis mounting.
• Compliance & Packaging — RoHS‑compliant and shipped in tray packing; part status: mass production.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling where 220 µF at 250 V is required and long life at 105°C is beneficial.
• Industrial power modules — Use in power conversion and control equipment that require polarized electrolytic bulk capacitance and robust ripple handling.
• Energy storage and DC rail support — Bulk energy buffering on DC rails and intermediate circuits within general‑purpose systems.

Unique Advantages

• Rated for extended high‑temperature operation: 3000 hours at 105°C under rated ripple current provides a verifiable endurance baseline for thermal stress conditions.
• Defined ripple performance across frequencies: Specified 1.0 A at 120 Hz and 1.5 A at 50 kHz supports both low‑frequency and higher‑frequency ripple environments.
• Low losses at measurement conditions: tan δ = 0.15 at 20°C, 120 Hz gives a clear metric for dissipation under typical test conditions.
• Compact snap‑in form factor: φ22 × 25L radial can with snap‑in terminals simplifies mechanical mounting and board accommodation in power assemblies.
• Production ready: RoHS compliance and tray packing support streamlined procurement and assembly for production volumes.
