LGN2Z122MELA45

The LGN2Z122MELA45 from Nichicon is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for high‑temperature, high‑ripple applications. It delivers 1.2 mF capacitance at a 180 V rating in a compact, smaller‑sized snap‑in package.

Engineered for general‑purpose power designs, this part combines elevated temperature endurance and robust ripple‑current capability—providing a reliable energy storage and smoothing solution for engineers specifying polarized electrolytic capacitors where space and thermal performance matter.

Key Features

• Electrical Performance — Rated capacitance of 1.2 mF with a tolerance of ±20% at 120 Hz, 20°C, and a rated voltage of 180 V.
• High‑Temperature Endurance — Specified to withstand 3000 hours application of rated ripple current at 105°C, with defined endurance limits and recovery characteristics per the LGN series datasheet.
• Ripple Current Handling — Ripple current ratings of 2.3 A at 120 Hz and 3.45 A at 100 kHz provide measurable AC stress capability for power circuits.
• Operating Temperature Range — Qualified for operation from −40°C to +105°C (per product specification).
• Mounting & Package — Snap‑in terminal radial can for secure board mounting; package case described as radial, can – snap‑in with physical size L: 4.5 × D: 2.5 cm.
• Polarized, General‑Purpose Design — Polarized construction suitable for DC power applications and general‑purpose use cases.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling where a 1.2 mF, 180 V polarized capacitor is required with elevated temperature endurance.
• Power supply energy storage — Local energy reservoir for power conversion stages that demand sustained ripple‑current performance at up to 105°C.
• Industrial electronics — Used in general‑purpose industrial control and power modules requiring reliable electrolytic capacitance in a snap‑in package.

Unique Advantages

• Proven high‑temperature reliability: Guaranteed 3000‑hour performance at 105°C under rated ripple conditions to support designs exposed to sustained elevated temperatures.
• Measured ripple capability: Specified ripple current values at both 120 Hz and 100 kHz allow designers to evaluate AC stress handling across common frequency ranges.
• Compact snap‑in packaging: Snap‑in radial can with a smaller case size (one rank smaller than LGU in the series) enables space‑constrained board layouts while maintaining secure mounting.
• Clear electrical specification: 1.2 mF at 180 V with ±20% tolerance simplifies selection and BOM documentation for polarized DC applications.
• RoHS‑compliant supply: Meets current RoHS requirements for environmentally constrained designs.
