LGN2W151MELB25

The LGN2W151MELB25 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose applications requiring high voltage and elevated temperature endurance. It combines a compact, smaller‑sized can with a 450 V rating and a 150 µF nominal capacitance.

Engineered for durability, this part withstands sustained rated ripple current at 105°C for extended periods, making it suitable where long endurance, compact snap‑in mounting, and reliable polarized capacitance are required.

Key Features

• Electrical Performance — 150 µF nominal capacitance at 450 V rated voltage with polarization suitable for DC applications; capacitance tolerance ±20%.
• High‑Temperature Endurance — Rated for operation up to 105°C with a specified lifetime of 3000 hours at 105°C when subjected to rated ripple current and DC bias.
• Rated Ripple Current — Designed to handle 790 mA at 120 Hz and 1.13 A at 100 kHz, supporting sustained ripple conditions per the datasheet endurance statement.
• Compact Snap‑in Package — Radial, can snap‑in construction in a one‑rank smaller case size than the LGU series, enabling denser board layouts where snap‑in mounting is required.
• Operating Range — Specified operating temperature range from −25°C to +105°C.
• Reliability Characteristics — Meets endurance and shelf‑life criteria from the series datasheet: capacitance change within ±20%, tan δ within specified limits, and leakage current within initial specified values after endurance testing.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Mechanical Dimensions — Compact footprint with dimensions L: 2.5 cm × D: 3.0 cm and snap‑in mounting for secure board attachment.

Typical Applications

• General Purpose — Suited for general‑purpose electronic circuits that require a polarized electrolytic capacitor with a 450 V rating and elevated temperature endurance.
• High‑Temperature Environments — Appropriate where operation up to 105°C and sustained ripple current capability (3000 hours at 105°C) are required.
• Compact Snap‑in Installations — Useful in designs needing snap‑in mounting and a reduced case size compared to the LGU series to save board area.

Unique Advantages

• High‑voltage capability — 450 V rating provides headroom for higher‑voltage DC circuits within the stated specifications.
• Long endurance at elevated temperature — Specified 3000‑hour endurance at 105°C under rated ripple current supports longer maintenance intervals and predictable aging.
• Compact snap‑in form factor — One rank smaller case than the LGU series enables tighter packing without sacrificing snap‑in reliability.
• Measured ripple performance — Published ripple current values at both low and high frequencies (790 mA at 120 Hz; 1.13 A at 100 kHz) allow designers to match the part to expected operating conditions.
• Clear electrical limits — Tolerance and leakage characteristics are specified, aiding accurate BOM selection and margin calculations.
• Regulatory compliance — RoHS conformity supports use in regions and products where restricted substance compliance is required.
