LGNW6181MELA30

The LGNW6181MELA30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series, offering 180 µF capacitance at a 420 V rating with ±20% tolerance. It is designed as a radial, can‑type snap‑in component for general‑purpose applications that require high voltage handling and long endurance.

Key performance attributes include a 3000‑hour endurance at 105°C, controlled loss (tanδ 0.15 at 20°C/120 Hz), defined leakage and ripple current specifications, and RoHS compliance—making it suitable for production designs that demand predictable electrical and thermal behavior.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance for bulk energy storage and DC link requirements.
• High‑Temperature Endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current, supporting sustained operation in elevated ambient conditions.
• Low Loss (tanδ) — Specified tanδ of 0.15 maximum at 20°C and 120 Hz, enabling controlled dissipation in AC ripple environments.
• Ripple Current Capability — 910 mA at 120 Hz (low frequency) and 1.301 A at 100 kHz (high frequency), supporting applications with continuous ripple stress.
• Leakage Current — Specified leakage current of 820 µA, providing predictable leakage characteristics after voltage application.
• Mounting & Package — Snap‑in terminal, radial can package (φ25 × 30 mm), designed for secure board mounting and mechanical stability.
• Environmental Compliance & Production — RoHS‑compliant, supplied in tray packing, and available in mass production quantities.

Typical Applications

• General‑purpose power systems — Provides 180 µF at 420 V with defined ripple current and leakage limits for general power electronics requiring reliable bulk capacitance.
• Power supply filtering — Suitable where DC link or smoothing capacitance is needed with controlled loss (tanδ) and ripple handling.
• Industrial equipment — Designed for applications that require long endurance at elevated temperatures (3000 h at 105°C) and robust mechanical mounting.

Unique Advantages

• High‑voltage capability: 420 V rating enables use in higher‑voltage circuits without stacking multiple components.
• Long endurance at elevated temperature: 3000‑hour rating at 105°C gives designers defined lifetime expectations under sustained stress.
• Broad ripple performance: Dual ripple specifications (910 mA @120 Hz and 1.301 A @100 kHz) support both low‑ and high‑frequency ripple environments.
• Predictable electrical losses: tanδ ≤ 0.15 at 20°C/120 Hz helps control heating and improves stability under AC conditions.
• Secure snap‑in mounting: Radial, can‑type snap‑in package (φ25 × 30 mm) simplifies robust PCB installation for through‑hole layouts.
• Production‑ready supply: Tray packing and mass production status support volume manufacturing and assembly workflows.
