LGN2P391MELZ30

The LGN2P391MELZ30 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGN series designed for general‑purpose electronic applications. It delivers 390 µF capacitance at a 220 V rating in a compact radial can snap‑in package and is specified for operation up to 105°C.

Key value propositions include high temperature endurance and defined ripple current capability, making this part suitable where reliable bulk capacitance and long life at elevated temperature are required.

Key Features

• Electrical Characteristics — 390 µF nominal capacitance with ±20% tolerance and a rated voltage of 220 V; polarized design for DC applications.
• Thermal and Endurance — Rated for an operating temperature range from −40°C to 105°C and specified to withstand 3000 hours of rated ripple current at 105°C.
• Ripple Current Handling — Low‑frequency ripple current: 1.34 A at 120 Hz; High‑frequency ripple current: 2.01 A at 100 kHz.
• Package & Mounting — Radial, can snap‑in package with snap‑in terminals for board mounting; compact size dimension L: 3 × D: 2.2 cm and seated height max 1.181 inch.
• Space‑Efficient Form Factor — One rank smaller case size than LGU, enabling reduced board footprint where space is constrained.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic circuits — For designs requiring a 390 µF, 220 V polarized snap‑in capacitor rated to 105°C.
• Power filtering and bulk capacitance — Suitable where defined ripple current capability and high‑temperature endurance are needed.
• Industrial and commercial equipment — Applicable to equipment specified to operate within −40°C to 105°C that requires robust electrolytic capacitance.

Unique Advantages

• High temperature endurance: Specified to withstand 3000 hours of rated ripple current at 105°C, supporting designs that operate at elevated temperatures.
• Defined ripple performance: Clear ripple current ratings at 120 Hz and 100 kHz allow predictable thermal and lifetime planning.
