LGN2Z122MELB35

The LGN2Z122MELB35 from Nichicon is a snap‑in, radial can aluminum electrolytic capacitor designed for general‑purpose power applications. It combines a smaller case size (one rank smaller than LGU) with high‑temperature endurance, supporting continuous operation up to 105°C.

This 1.2 mF, 180 V polarized capacitor is intended for engineers who need robust ripple handling and long life in compact power assemblies, offering reliable capacitance stability and specified ripple current performance across common power frequencies.

Key Features

• Capacitance & Voltage: 1.2 mF nominal capacitance with a 180 V rated voltage and ±20% tolerance, suitable for bulk energy storage and filtering in power circuits.
• High‑temperature Endurance: Rated for operation from –40°C to +105°C (applicable for the 180 V rating) with a guaranteed endurance of 3000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Snap‑In Radial Can Package: Snap‑in mounting provides secure board attachment for vertical power module designs and simplifies assembly in high‑current power sections.
• Ripple Current Capability: Specified ripple performance of 2.3 A at 120 Hz and 3.45 A at 100 kHz, enabling effective smoothing in both low‑ and high‑frequency power stages.
• Compact Mechanical Size: Physical footprint defined as L: 3.5 × D: 3 cm with a seated height up to 1.378 inch, delivering a smaller case size option within the LGN series.
• RoHS Compliant: Meets RoHS requirements (2011/65/EU, (EU)2015/863) and is marked with white lettering on a black sleeve for clear identification.

Typical Applications

• Power Supply Bulk Filtering: Used for smoothing and energy storage in AC–DC and DC–DC converters where high ripple endurance and compact size are required.
• Industrial Power Modules: Suitable for motor drive and industrial controller power stages that demand sustained performance at elevated temperatures.
• UPS and Power Conditioning: Employed in uninterruptible power supplies and conditioning circuits to support transient loads and maintain voltage stability.

Unique Advantages

• High‑temperature reliability: 3000‑hour endurance at 105°C under rated ripple conditions ensures predictable performance in thermally demanding installations.
• Compact form factor: One rank smaller case than the LGU series allows designers to reduce board area without sacrificing ripple performance.
• Broad ripple frequency handling: Rated ripple currents at both 120 Hz and 100 kHz support diverse power conversion topologies and switching frequencies.
• Clear polarity and marking: Polarized design with visible sleeve markings simplifies assembly and inspection in production environments.
• RoHS compliance: Environmental compliance reduces regulatory overhead for products destined for global markets.
