LGA2W221MELB25

The LGA2W221MELB25 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose electronic applications requiring high capacitance and sustained ripple handling. It is a radial, can‑type, polarized capacitor rated at 450 V with a capacitance of 220 µF.

Engineered for elevated‑temperature endurance, the part withstands extended application of rated ripple current at 105°C and is RoHS compliant, making it appropriate for designs where long life and reliable ripple performance are required.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 450 V, providing bulk energy storage in high‑voltage circuits.
• High Ripple Current Capability — Rated ripple handling of 1.59 A (120 Hz) and an equivalent of 2.274 A at 50 kHz, supporting AC ripple conditions across a range of frequencies.
• Long Life at Elevated Temperature — Endurance specified as 5000 hours at 105°C with D.C. bias plus rated ripple current; capacitance change is within ±20% after the endurance test.
• Operating Temperature Range — Usable from −40°C to +105°C to cover common industrial and commercial thermal environments.
• Snap‑In Radial Can Package — Snap‑in mounting type and radial can (snap‑in) package for secure board attachment and straightforward assembly.
• Leakage and Dissipation Characteristics — Leakage current limited by I ≤ 3√(C·V) μA (after 5 minutes at 20°C); tan δ ≤ 0.20 (120 Hz, 20°C).
• Size — φD × L = 30 × 25 mm package (size dimension 3.0 cm × 2.5 cm as supplied).
• Regulatory — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power circuitry — Bulk capacitance and rated 450 V withstand voltage make it suitable where high‑voltage smoothing and energy storage are required.
• High‑ripple environments — Designed for applications that impose sustained ripple currents at elevated temperatures, leveraging its 1.59 A (120 Hz) rating and long endurance at 105°C.
• Industrial and commercial electronics — The −40°C to +105°C operating range and long life at high temperature support robust operation in demanding installations.

Unique Advantages

• High voltage, high capacitance combination: 220 µF at 450 V provides significant bulk energy in a compact snap‑in can.
• Proven high‑temperature endurance: Rated for 5000 hours at 105°C under DC bias plus ripple, supporting long service life in hot operating conditions.
• Frequency‑flexible ripple handling: Clear ripple current ratings at 120 Hz and calculated equivalence at 50 kHz help designers predict performance across frequencies.
• Measured electrical stability: Endurance requirements limit capacitance drift to ±20% and ensure leakage current remains at or below initial specified levels after life testing.
• RoHS compliance: Meets relevant RoHS directives for restricted substances.
