LGR2G471MELC50

The LGR2G471MELC50 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGR long‑life series. It delivers 470 µF at a 400 V rating in a radial can snap‑in package designed for high‑voltage, general‑purpose power applications.

Engineered for elevated operating temperatures, this part is specified for continuous use from −25 °C to 105 °C and is rated to withstand 10,000 hours of DC bias plus rated ripple current at 105 °C. It is RoHS compliant for environmental conformity.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 400 V with tolerance of −20% to +20% for bulk energy storage and smoothing in high‑voltage circuits.
• High‑Temperature Long Life — Endurance specified as 10,000 hours at 105 °C under DC bias plus rated ripple current; suitable for sustained high‑temperature operation (operating range −25 °C to 105 °C).
• Ripple Current Performance — Rated ripple current of 1.4 A at 120 Hz and 2.002 A at 50 kHz; frequency coefficient for the 400 V range rises to 1.43 at 50 kHz or higher, supporting higher ripple capacity at elevated frequencies.
• Package & Mounting — Snap‑in terminal, radial can construction (polarized); physical size L: 5 × D: 3.5 cm for robust board mounting and secure mechanical retention.
• Electrical Stability — Specified tangent of loss angle (tan δ) maximum of 0.15 at 120 Hz and 20 °C for the 200–400 V range; leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20 °C.
• Endurance & Shelf Life — After endurance testing the capacitor meets defined limits (capacitance change within ±25%, tan δ ≤ 250% of initial spec, leakage current ≤ initial spec); shelf life and recovery characteristics are specified in the LGR series datasheet.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power supplies — Bulk smoothing and energy storage where a 400 V rating and high ripple endurance at elevated temperature are required.
• Power conversion and DC‑link filtering — Suitable for DC‑link and filter roles benefiting from high ripple current capability and long life at 105 °C.
• Industrial power equipment — General‑purpose high‑voltage filtering in industrial systems that demand sustained performance under thermal stress.
• General‑purpose high‑voltage circuits — Applications requiring reliable polarized aluminum electrolytic capacitors with snap‑in mounting and RoHS compliance.

Unique Advantages

• Long, specified operational life — 10,000 hours endurance at 105 °C under rated conditions reduces the need for frequent replacement in high‑temperature installations.
• Designed for high ripple workloads — Explicit ripple current specs at both low and high frequencies (1.4 A at 120 Hz; 2.002 A at 50 kHz) plus frequency coefficients support reliable filtering across wide frequency bands.
• High voltage capability — 400 V rating enables use in higher‑voltage power systems without component stacking.
• Robust snap‑in mounting — Radial, can‑style snap‑in terminals provide secure board retention and straightforward assembly for power boards and chassis applications.
• Measurable electrical stability — Specified limits for tan δ and leakage current, with clear end‑of‑life and shelf‑life criteria, support predictable performance and maintenance planning.
• Regulatory compliance — RoHS conformity supports deployments where restricted‑substance compliance is required.
