LGNW6471MELB45

The LGNW6471MELB45 is a Nichicon LGN series snap‑in aluminum electrolytic capacitor providing 470 µF capacitance at a 420 V rating. It combines high voltage capability with extended endurance and compact, snap‑in can packaging for general purpose electronic applications.

Designed for continuous operation up to 105 °C with a rated lifetime of 3000 hours at 105 °C, this part targets designs that require robust ripple handling and reliable long‑term performance in a smaller case footprint.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 420 V, with a capacitance tolerance of −20% to +20%.
• High Temperature Endurance — Specified for operation from −25 °C to +105 °C and endurance of 3000 hours at 105 °C under rated ripple and DC bias.
• Ripple Current Capability — Low‑frequency ripple current of 1.86 A (120 Hz) and high‑frequency ripple current of 2.66 A (100 kHz), supporting continuous ripple duty.
• Dielectric Loss (tan δ) — tan δ (DF) of 0.15 measured at 20 °C, 120 Hz, indicating specified dissipation characteristics.
• Leakage Current — Leakage current of 1330 µA (measured after rated voltage application conditions as specified).
• Snap‑In, Radial Can Package — Snap‑in terminal type in a radial can package for secure board mounting; physical size φ30 × 45L mm.
• Environmental Compliance — RoHS compliant; available in tray packing and in mass production status.

Typical Applications

• General Purpose — High Voltage Requirements — When a 420 V rated capacitor is required in general purpose electronic equipment, this part provides established voltage capability with 470 µF capacitance.
• General Purpose — High Ripple Environments — Suitable for general purpose designs that require continuous ripple handling up to 1.86 A at 120 Hz and 2.66 A at higher frequencies.
• General Purpose — Elevated Temperature Duty — For general purpose applications needing sustained operation at temperatures up to 105 °C with 3000‑hour endurance.

Unique Advantages

• Long Lifetime at Elevated Temperature: 3000 hours endurance at 105 °C under rated conditions provides predictable long‑term performance for demanding thermal environments.
• High Voltage & High Capacitance Combination: 470 µF at 420 V supports designs that require both significant energy storage and high voltage rating in a single component.
• Robust Ripple Handling: Specified ripple current values at both low and high frequencies enable reliable operation under continuous AC stress.
• Compact Snap‑In Can: φ30 × 45L radial snap‑in package delivers a smaller‑sized footprint (one rank smaller case than LGU in the series) while maintaining snap‑in mounting convenience.
• Measured Dissipation and Leakage Specs: Clear tan δ and leakage current specifications allow predictable thermal and standby behavior in system design.
• Production Readiness: RoHS compliant and in mass production with tray packing for straightforward procurement and assembly.
