LGN2P331MELY35

The LGN2P331MELY35 is a Nichicon LGN-series aluminum electrolytic capacitor in a snap‑in, radial can package designed for general-purpose power applications. It provides 330 µF capacitance at a 220 V rating with polarized terminals and a compact, smaller-sized case compared with the LGU series.

Engineered for elevated-temperature operation, this part is specified for –40 °C to 105 °C and withstands 3000 hours of rated ripple-current application at 105 °C, making it suitable where sustained thermal and ripple endurance are required. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 220 V and ±20% tolerance, suited to bulk energy storage and DC bus smoothing in systems that require this voltage/capacitance point.
• High‑Temperature Endurance — Rated for operation up to 105 °C and specified to withstand 3000 hours of rated ripple-current application at 105 °C (endurance conditions per series datasheet).
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure PCB retention and a smaller case size relative to LGU-series parts, enabling denser power assemblies.
• Ripple Current Performance — Rated ripple current of 1.26 A at 120 Hz and 1.89 A at 100 kHz, supporting AC ripple handling across low and high frequencies.
• Operating Range & Polarization — Polarized capacitor with an operating temperature range of –40 °C to 105 °C and a specified leakage current limit per datasheet formula (I ≤ 3/√C µA after 5 minutes at 20 °C).
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Filtering — Bulk filtering and smoothing on 220 V circuits where a 330 µF, high‑temperature capacitive solution is required.
• DC Bus & Energy Storage — Local energy storage and transient buffering in power conversion modules that operate up to 105 °C.
• Industrial Electronics — Power assemblies and control electronics needing a snap‑in electrolytic with rated ripple current and extended high‑temperature endurance.

Unique Advantages

• Extended high‑temperature endurance: Specified to tolerate 3000 hours of rated ripple current at 105 °C, supporting reliability in thermally demanding installations.
• Compact, serviceable package: Snap‑in radial can with a case size one rank smaller than LGU-series parts, aiding higher component density without sacrificing mounting robustness.
• Frequency‑spanning ripple capacity: Explicit ripple current ratings at 120 Hz (1.26 A) and 100 kHz (1.89 A) provide predictable AC stress handling across common power frequencies.
• Defined leakage and endurance characteristics: Leakage current limits and endurance/shelf‑life criteria are specified in the series datasheet, enabling predictable performance planning and qualification.
• RoHS compliant: Conforms to RoHS (2011/65/EU, (EU)2015/863) for environmental compliance in regulated markets.
