LGN2V471MELB40

The LGN2V471MELB40 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series designed for general‑purpose power applications. It delivers 470 µF at 350 V in a compact radial can with snap‑in mounting, optimized for elevated operating temperatures up to 105°C.

Built for systems requiring sustained ripple endurance and compact board mounting, this part combines the LGN series’ high‑temperature endurance with RoHS compliance for commercial and industrial power designs.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 350 V, suitable for bulk filtering and energy storage in high‑voltage DC circuits.
• High‑Temperature Endurance — Rated for operation to 105°C with endurance specified as 3000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑In Radial Can Package — Snap‑in termination and radial can package provide secure board retention and straightforward assembly for power supply and industrial PCBs.
• Compact Footprint — Smaller case sizing within the LGN series (one rank smaller than LGU) and physical size of L: 4 × D: 3 cm for tighter board layouts.
• Ripple Current Capability — Rated ripple current of 1.4 A at 120 Hz and 2.002 A at 100 kHz, enabling effective AC ripple handling in power applications.
• Electrical Stability — Capacitance tolerance ±20% (measured at 120 Hz, 20°C) and low leakage behavior consistent with series spec (I ≤ 3/√C μA after 5 minutes at 20°C).
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for environmental compliance.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in AC/DC and DC/DC power supplies where 350 V rating and elevated temperature endurance are required.
• Industrial Control — Energy buffering and ripple suppression in motor drives, PLCs, and factory automation equipment operating at elevated temperatures.
• Power Conversion — Support for power conversion stages and intermediate DC links that demand sustained ripple capability and reliable high‑voltage performance.

Unique Advantages

• Compact, space‑saving design — One rank smaller case than the LGU series reduces board area without sacrificing capacitance or voltage rating.
• Designed for sustained high‑temperature use — 3000‑hour endurance at 105°C under rated ripple current ensures long service life in hot environments.
• Measured ripple performance — Specified ripple current at both low (120 Hz) and high (100 kHz) frequencies supports a range of switching and line‑frequency applications.
• Practical assembly with snap‑in terminals — Snap‑in mounting provides mechanical stability for through‑hole PCB assembly in power modules and chassis installations.
• Predictable electrical characteristics — ±20% capacitance tolerance and series leakage specifications enable accurate design margins and predictable performance.
• Environmental compliance — RoHS conformity supports product designs targeting regulated markets and corporate sustainability goals.
