LGN2W221MELC25

The LGN2W221MELC25 is a polarized aluminum electrolytic capacitor in a snap‑in terminal, radial can package engineered for general‑purpose electronic applications. It provides 220 µF capacitance at a 450 V rating with a −25 °C to 105 °C operating range and is RoHS compliant.

Designed for elevated temperature operation, this part withstands 3000 hours of rated ripple current at 105 °C and is offered in a compact, one‑rank‑smaller case than the LGU series to support denser assemblies.

Key Features

• Capacitance and Voltage: 220 µF rated capacitance at 450 V suitable for high‑voltage, polarized applications.
• High‑temperature endurance: Rated to operate up to 105 °C and specified to withstand 3000 hours of DC bias plus rated ripple current at 105 °C.
• Ripple current capability: Rated ripple current of 1.05 A at 120 Hz and 1.502 A at 100 kHz to support AC ripple handling under load.
• Low‑temperature stability: Impedance ratio Z(–25 °C)/Z(+20 °C) ≤ 8 for the 350–600 V range, maintaining defined performance at cold conditions.
• Electrical loss and leakage: Maximum tan δ of 0.20 for the 450–600 V range (measured at 120 Hz, 20 °C). Leakage current meets I ≤ 3/√C (µA) after 5 minutes at 20 °C (C = rated capacitance in µF).
• Package and mounting: Snap‑in, radial can package (polarized) with compact dimensions L: 2.5 cm × D: 3.5 cm and a seated height maximum of 2.5 cm.
• Tolerance and polarization: Capacitance tolerance ±20% and polarized construction for correct DC application.
• Regulatory compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic assemblies: Used where a polarized 220 µF, 450 V snap‑in capacitor is required for bulk capacitance in assemblies rated for elevated temperatures.
• Power electronics modules: Applied in circuits that require high‑voltage capacitance and defined ripple current handling at elevated operating temperatures.
• Industrial equipment: Suitable for general‑purpose roles in industrial designs that need a compact, high‑voltage electrolytic capacitor with extended endurance at 105 °C.

Unique Advantages

• Extended high‑temperature life: Specified endurance of 3000 hours at 105 °C under rated ripple current preserves capacitance and leakage characteristics over prolonged elevated‑temperature use.
• Compact, higher‑density mounting: One rank smaller case size than the LGU series enables denser board or chassis layouts without sacrificing rated voltage or capacitance.
• Clear performance limits: Defined tan δ, leakage current formula, and impedance ratios provide measurable electrical parameters for design validation.
• Robust ripple handling: Provided ripple current ratings at both low and high frequencies allow designers to size the capacitor confidently for expected AC stress.
• Regulatory readiness: RoHS compliance supports deployments where restricted‑substance conformance is required.
