LGNW6181MELB25

The LGNW6181MELB25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series. It delivers 180 µF capacitance at a 420 V rated voltage in a compact φ30 × 25L radial can designed for general‑purpose power applications.

Engineered for robust ripple endurance and elevated operating temperatures, this part targets general‑purpose power electronics where reliable bulk capacitance and long life under DC bias and ripple are required.

Key Features

• Capacitance and Voltage: 180 µF nominal capacitance at a 420 V rated voltage, with a tolerance of ±20% (120 Hz, 20°C).
• High Temperature Endurance: Rated for 3,000 hours at 105°C with DC bias plus rated ripple current; meets LGN series endurance requirements when restored to 20°C after testing.
• Ripple Performance: Low‑frequency ripple current 910 mA at 120 Hz and high‑frequency ripple current 1.301 A at 100 kHz, supporting applications with continuous ripple loading.
• Low Loss Characteristic: Tangent of loss angle (tan δ) up to 0.15 measured at 120 Hz, 20°C for rated voltages up to 420 V for controlled dissipation.
• Leakage Current: Specified leakage current at 820 µA, measured after standard charge conditions.
• Robust Operating Range: Rated for operation from −25°C to +105°C, consistent with the series’ high‑voltage temperature category.
• Package & Mounting: Snap‑in radial can (φ30 × 25L) for secure board mounting; supplied in tray packing and listed as mass production status.
• Compliance: RoHS‑compliant per the LGN series declaration.

Typical Applications

• General‑purpose power equipment: Bulk smoothing and energy storage where a 420 V, 180 µF snap‑in capacitor is required.
• Power supplies and converters: Applications that require high ripple endurance at elevated temperatures.
• Industrial electronics: General‑purpose circuits needing reliable polarized capacitance in a compact snap‑in package.

Unique Advantages

• Designed for prolonged high‑temperature ripple: 3,000 hours endurance at 105°C under rated ripple current provides predictable life under continuous load.
• Measurable ripple capability: Specified low‑ and high‑frequency ripple ratings (910 mA at 120 Hz, 1.301 A at 100 kHz) help designers size capacitors to real‑world loading conditions.
• Compact snap‑in form factor: φ30 × 25L radial can offers space‑efficient mounting and secure PCB retention for power assemblies.
• Controlled dielectric losses: tan δ ≤ 0.15 (120 Hz, 20°C) supports stable dissipation characteristics at rated voltage.
• RoHS compliance and production readiness: Tray packing and mass production status simplify procurement and assembly for volume designs.
