LGN2Z122MELC30

The LGN2Z122MELC30 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 1.2 mF capacitance at a 180 V rating in a compact, radial can snap‑in package.

Engineered for elevated temperature operation, this device is specified for –40°C to 105°C and is rated to withstand 3000 hours of rated ripple current at 105°C. Its smaller case size (one rank smaller than LGU) and RoHS compliance make it suitable for space‑constrained assemblies with robust thermal and ripple requirements.

Key Features

• Electrical Performance — 1.2 mF capacitance with a rated voltage of 180 V and polarization for DC power applications.
• Ripple Current Capability — Rated ripple current of 2.3 A at 120 Hz and 3.45 A at 100 kHz, enabling effective smoothing under continuous ripple loading.
• High‑Temperature Endurance — Specified operating range from –40°C to 105°C and endurance of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current.
• Compact Snap‑In Package — Radial, can snap‑in mounting simplifies PCB retention and mechanical stability in power assemblies; dimension approximately L: 3 × D: 3.5 cm with a seated height up to 1.181 inch.
• Tolerance & Stability — Capacitance tolerance of −20% to +20% and endurance/shelf life characteristics defined to maintain capacitance and leakage performance after specified stress and storage.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power circuits — Provides bulk capacitance and ripple handling for mid‑voltage DC power supplies where 180 V and 1.2 mF are required.
• Power conditioning — Suitable for smoothing and decoupling in assemblies operating up to 105°C and subjected to continuous ripple current.
• Industrial power electronics — Compact snap‑in form factor helps when space is limited and long ripple endurance at elevated temperature is needed.

Unique Advantages

• High ripple endurance: Rated to withstand 3000 hours of rated ripple current at 105°C, supporting continuous high‑stress operation.
• Dual‑frequency ripple ratings: Published ripple currents at both 120 Hz (2.3 A) and 100 kHz (3.45 A) allow designers to assess performance across low and high frequency conditions.
• Space‑efficient design: One rank smaller case size than the LGU series enables reduced board area without sacrificing rated voltage or capacitance.
• Wide operating temperature range: –40°C to 105°C rating supports deployment in environments with thermal extremes within that range.
• Robust mounting: Snap‑in radial can package offers secure mechanical retention for power modules and chassis‑mounted assemblies.
• RoHS compliant: Meets current RoHS requirements for environmentally conscious designs.
