LASW6151MELZ40

The LASW6151MELZ40 is a snap-in terminal, large-can aluminum electrolytic capacitor from Nichicon's LAS series. It delivers 150 µF capacitance at a 420 V rating with a compact φ22 × 40 mm can and is intended for general-purpose power applications.

Designed for high-temperature operation and fluctuating-voltage environments, this capacitor combines 105°C endurance, elevated ripple-current capability, and enhanced safety features for use in industrial and commercial power equipment.

Key Features

• Capacitance & Tolerance — 150 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 420 V DC nominal rating for high-voltage power circuits.
• Temperature Endurance — Operating temperature range −25°C to +105°C with a rated endurance of 2000 hours at 105°C under rated ripple current.
• High Ripple Current — Low-frequency ripple current 820 mA (120 Hz) and high-frequency ripple current 943 mA (10 kHz) to support smoothing and filtering in power conversion stages.
• Loss and Leakage — Maximum tan δ of 0.20 (120 Hz, 20°C) and leakage current specified at 750 µA.
• Mounting & Package — Snap-in terminal, radial can package (φ22 × 40 mm) supplied in tray packing for automated handling.
• Safety & Reliability — LAS series improvements for abnormally excessive voltage and a pressure relief vent designed to operate without flames, ignition, or dispersion of parts.
• RoHS Compliance — Product is RoHS compliant.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage where 420 V ratings and elevated ripple handling are required.
• Industrial power equipment — Designed for use in equipment exposed to voltage fluctuations and elevated ambient temperatures.
• Power conversion and filtering — Suitable for DC link, inverter and converter filtering duties that demand sustained ripple current and long-term stability at 105°C.

Unique Advantages

• High-voltage capability: 420 V rating enables use in higher-voltage power rails without series stacking.
• Long thermal endurance: 2000 hours at 105°C under rated conditions supports reliable operation in high-temperature environments.
• Elevated ripple handling: 820 mA (120 Hz) and 943 mA (10 kHz) ripple current ratings reduce thermal stress during filtering and smoothing tasks.
• Compact snap-in form factor: φ22 × 40 mm large-can construction with snap-in terminals facilitates robust mounting and higher current handling in constrained spaces.
• Enhanced safety features: Built-in pressure relief and improved safety design for abnormally excessive voltage scenarios improve field reliability.
• Regulatory readiness: RoHS compliance supports deployment in regions with restricted substances requirements.
