LGN2G471MELB45

The LGN2G471MELB45 is a 470 µF, 400 V aluminum electrolytic capacitor from Nichicon's LGN series. It uses a snap‑in terminal radial can package and is designed for general‑purpose applications that require high voltage handling, bulk capacitance and extended high‑temperature endurance.

Key value comes from its 105°C rating with proven endurance—designed to withstand 3000 hours of rated ripple current at 105°C—combined with a smaller case profile relative to the LGU family for denser board layouts.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 400 V rated voltage, suitable where bulk energy storage or high‑voltage filtering is required.
• High‑temperature Endurance — Rated for operation up to 105°C with an endurance specification of 3000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑in Radial Can Package — Snap‑in terminals for secure mounting and efficient assembly in power and industrial boards; one rank smaller case size than the LGU series for space‑efficient designs.
• Ripple Current Capability — Rated ripple performance of 1.68 A at 120 Hz and 2.402 A at 100 kHz to support filtering and smoothing under AC ripple conditions.
• Operating Temperature Range — Specified for −25°C to +105°C consistent with 400 V class parts in the LGN family.
• Electrical Stability — Capacitance tolerance ±20% (120 Hz, 20°C) and leakage current behavior per series specification (I ≤ 3/√C µA after 5 minutes at 20°C).
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk smoothing and filtering in circuits that require a 400 V rated capacitor with 470 µF capacitance and robust ripple handling.
• High‑temperature environments — Where operation at up to 105°C and long endurance (3000 hours at 105°C) under rated ripple current is necessary.
• Space‑constrained power assemblies — Applications that benefit from a smaller case size than LGU while maintaining high voltage and capacitance.

Unique Advantages

• Extended endurance at elevated temperature — 3000 hours at 105°C under rated ripple current provides predictable long‑term performance in hot operating conditions.
• High DC voltage capability — 400 V rating supports higher‑voltage rails without stacking multiple lower‑voltage parts.
• Compact snap‑in form factor — Radial snap‑in can and a one‑rank smaller case than LGU help reduce PCB footprint and simplify assembly.
• Defined ripple performance — Specified ripple currents at 120 Hz and 100 kHz (1.68 A and 2.402 A respectively) enable engineers to design to measurable AC stress limits.
• Measurable electrical limits — Capacitance tolerance ±20% and leakage current characterized by I ≤ 3/√C µA support deterministic electrical design margins.
• RoHS compliance — Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances.
