LGN2V331MELZ45

The LGN2V331MELZ45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGN series. It delivers 330 µF capacitance at a 350 V rating in a smaller‑sized snap‑in radial can designed for general‑purpose power applications.

Engineered for elevated operating conditions, this part is specified for use from ‑25 °C to 105 °C and is rated to withstand 3,000 hours of rated ripple current at 105 °C. It is RoHS compliant and sized for compact radial, snap‑in mounting.

Key Features

• Electrical Capacity — 330 µF nominal capacitance with a rated voltage of 350 V and ±20% tolerance at 120 Hz, 20 °C.
• High‑temperature Endurance — Endurance specified for 3,000 hours at 105 °C when D.C. bias plus rated ripple current is applied; capacitance change and leakage are specified after restoration to 20 °C.
• Ripple Current Handling — Rated ripple current performance of 1.2 A at 120 Hz and 1.716 A at 100 kHz, enabling sustained ripple operation at rated conditions.
• Operating Temperature Range — Specified for −25 °C to +105 °C for 350 V parts, supporting designs exposed to elevated ambient temperatures.
• Package & Mounting — Radial, snap‑in can package for secure PCB mounting; compact dimensions L: 4.5 × D: 2.2 cm reduce board area versus larger LGU cases.
• Leakage and Loss Characteristics — Series specifications include leakage current I ≤ 3/√(C) µA after 5 minutes at 20 °C and a tan δ limit appropriate for the voltage range.
• Low‑temperature Stability — Impedance ratio Z(−25 °C)/Z(+20 °C) is specified (up to 8 for 350–600 V range), indicating defined behavior at low temperatures for the series.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in medium‑voltage power supplies where 350 V and high‑temperature endurance are required.
• Industrial power conversion — Energy storage and decoupling in converters and controllers that operate at elevated temperatures up to 105 °C.
• General‑purpose electronic equipment — Radial snap‑in mounting for applications needing secure board anchoring and a compact high‑voltage capacitor solution.

Unique Advantages

• Compact footprint: One rank smaller case size than LGU, allowing reduced PCB area without sacrificing voltage or capacitance.
• High‑temperature durability: Specified 3,000‑hour endurance at 105 °C supports long‑term operation in hot environments.
• Defined ripple capability: Published ripple current ratings at both low and high frequencies (120 Hz and 100 kHz) provide clear design margins for ripple handling.
• Secure snap‑in mounting: Radial, snap‑in can construction simplifies mechanical retention and through‑hole assembly for higher‑stability installations.
• Series scalability: Part of the Nichicon LGN family with rated voltages from 160 to 600 V and capacitances across the series, making it straightforward to select compatible sizes and ratings.
• Regulatory compliance: RoHS conformity supports restricted‑substance requirements for commercial and industrial products.
