LGUW6151MELB

The LGUW6151MELB is a 150 µF, 420 V aluminum electrolytic capacitor from Nichicon's LGU series, designed as a snap‑in terminal radial can for general-purpose applications. It offers high-voltage capacitance in a compact φ30 × 25 mm package with rated endurance at elevated temperature.

Engineered for demanding ambient conditions, this snap‑in capacitor delivers long life at 105°C with specified ripple handling across low and high frequencies, making it suitable for bulk energy storage and power-conditioning needs in general-purpose electronic equipment.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance rated for 420 V DC, with a tolerance of −20% to +20%.
• Thermal Endurance — Rated operating temperature range −25°C to 105°C with a guaranteed life of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Handles 880 mA at 120 Hz (low frequency) and 1.258 A at 50 kHz (high frequency), supporting both mains‑frequency and higher‑frequency power applications.
• Low Dissipation Factor — tan δ = 0.15 (measured at 20°C, 120 Hz), indicating efficient operation with controlled loss at the rated voltage class.
• Leakage Current — Specified leakage current of 750 µA (after standard voltage application at 20°C), for predictable DC performance.
• Mechanical & Mounting — Snap‑in radial can package (φ30 × 25 mm) for secure board mounting; supplied in tray packing for production handling.
• Regulatory — RoHS compliant.

Typical Applications

• Power supplies — Bulk capacitance and ripple handling for high‑voltage DC link filtering and smoothing in general-purpose power supply designs.
• Industrial electronics — Energy storage and decoupling in industrial control and power conversion equipment operating up to 420 V and elevated ambient temperatures.
• High-voltage assemblies — Use where compact, snap‑in high‑voltage capacitors are required for board‑level mounting and reliable high-temperature performance.

Unique Advantages

• 420 V rating for high-voltage designs: Enables use in DC link and high-voltage power stages without series stacking.
• 3000‑hour life at 105°C: Provides durable long‑term performance under continuous rated ripple conditions, reducing maintenance and replacement frequency.
