LGN2Z222MELB50

The LGN2Z222MELB50 is a Nichicon LGN series aluminum electrolytic capacitor in a snap‑in radial can package. It provides 2.2 mF capacitance at a rated voltage of 180 V with polarized terminals and snap‑in mounting for robust board retention.

Designed for general‑purpose power electronics, this part is specified for operation from −40 °C to +105 °C and is endurance rated for 3000 hours at 105 °C with rated ripple current, offering stable bulk capacitance and ripple handling for demanding thermal environments.

Key Features

• Capacitance & Voltage: 2.2 mF capacitance rated at 180 V for bulk energy storage and smoothing in higher‑voltage circuits.
• High‑temperature Endurance: Specified lifetime of 3000 hours at 105 °C when subjected to D.C. bias plus rated ripple current, supporting sustained operation in elevated ambient temperatures.
• Ripple Current Capability: Rated ripple current of 2.9 A at 120 Hz and 4.35 A at 100 kHz, supporting both low‑frequency and high‑frequency ripple environments.
• Snap‑in Radial Can Package: Snap‑in mounting for secure PC‑board retention and mechanical stability in vertical can format (radial, can - snap‑in).
• Operating Temperature Range: −40 °C to +105 °C, enabling use across a broad temperature span applicable to many industrial and electronic systems.
• Tolerance & Polarization: Capacitance tolerance −20% to +20% with polarized construction; leakage current and tan δ specifications per series datasheet apply.
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint: Physical size L: 5 × D: 3 cm, providing a smaller case option within the LGN family while maintaining rated performance.

Typical Applications

• Power supply bulk smoothing — Provides bulk capacitance and ripple absorption in higher‑voltage DC power rails where 180 V rating and high ripple tolerance are required.
• Industrial power electronics — Designed for use in equipment operating at elevated temperatures up to 105 °C with long endurance under rated ripple current.
• Energy storage for converters — Suitable for DC link or intermediate storage in converters and inverters requiring polarized, high‑capacitance components.

Unique Advantages

• Proven high‑temperature endurance: 3000‑hour rating at 105 °C under rated ripple current ensures predictable long‑term performance in hot operating environments.
• High ripple handling across frequencies: Specified ripple currents at both 120 Hz and 100 kHz accommodate designs with low‑frequency and high‑frequency ripple components.
• Space‑efficient LGN family sizing: One rank smaller case size than the LGU series provides compactness without sacrificing ripple or endurance performance.
• Robust mounting: Snap‑in radial can construction delivers reliable mechanical retention for vertical board mounting and easy assembly.
• Wide operating range: −40 °C to +105 °C operation supports diverse ambient conditions common in industrial and commercial systems.
