LGN2V121MELZ25

The LGN2V121MELZ25 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage, general‑purpose applications. It delivers 120 µF at a 350 V rating in a compact, radial can (snap‑in) package optimized for reliable power filtering and energy storage in constrained assemblies.

Engineered for elevated operating temperatures, this LGN series part withstands long‑term ripple current at 105°C and is supplied in a one‑rank smaller case than the LGU series, offering a balance of density and thermal endurance for industrial and power electronics designs.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a rated voltage of 350 V and ±20% tolerance, suitable for high‑voltage DC link and filtering roles.
• High‑Temperature Endurance — Specified operating temperature range of −25°C to +105°C and rated for 3000 hours of DC bias plus rated ripple current at 105°C.
• Ripple Current Capability — Rated ripple current of 750 mA at 120 Hz and 1.073 A at 100 kHz, supporting demanding AC ripple environments across frequency ranges.
• Electrical Stability — Loss tangent (tan δ) consistent with LGN series limits for the 160–420 V category (tan δ max 0.15), and low‑temperature impedance stability with Z(−25°C)/Z(+20°C) up to 8 for 350–600 V parts.
• Package & Mounting — Radial, snap‑in can package (L: 2.5 × D: 2.2 cm) for secure board mounting; one rank smaller case size compared to LGU series to save PCB space.
• Polarized Design — Conventional polarized electrolytic configuration for bulk energy storage and smoothing applications.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in high‑voltage DC supplies up to the 350 V rating.
• DC link and energy storage — Local energy reservoir for converters and inverters where elevated ripple current and temperature endurance are required.
• Industrial power electronics — General‑purpose filtering and decoupling in industrial control and power modules operating to 105°C.

Unique Advantages

• Compact high‑voltage package — One rank smaller case than LGU series lets designers reduce board area without sacrificing voltage rating.
• Long high‑temperature lifetime — Rated for 3000 hours under DC bias plus rated ripple at 105°C, supporting reliability in thermally stressed environments.
• Wide ripple performance — Specified ripple current at both low and high frequencies (750 mA @120 Hz, 1.073 A @100 kHz) for versatile application across switching supplies.
• Thermal and impedance stability — Specified impedance ratio at low temperature (Z(−25°C)/Z(+20°C) up to 8) and tight tan δ limits for predictable performance.
• Secure snap‑in mounting — Radial snap‑in terminals for robust mechanical retention in high‑vibration or high‑current PCBs.
• RoHS compliant — Meets current RoHS directive requirements for environmental regulatory compliance.
