LAS2W151MELB25

The LAS2W151MELB25 is a Nichicon LAS series snap-in aluminum electrolytic capacitor specified at 150 µF and 450 V. It combines a compact radial can snap-in package with performance characteristics targeted for general-purpose applications and equipment operating where line voltage can fluctuate.

Key value comes from its 105°C endurance, high ripple current capability across frequency, and built-in safety measures for abnormal over-voltage conditions, making it suitable for demanding power circuits requiring reliable high-voltage bulk capacitance.

Key Features

• Electrical characteristics: 150 µF nominal capacitance with tolerance of -20% to +20% and maximum tan δ of 0.20 (measured at 20°C, 120 Hz).
• High voltage rating: Rated for 450 V DC to support higher-voltage power systems and bulk energy storage.
• Ripple current capability: Low-frequency ripple current 880 mA at 120 Hz and high-frequency ripple current 1.012 A at 10 kHz, with frequency-dependent ripple allowance per series specifications.
• Leakage current: Specified leakage current of 770 µA (measured after rated voltage application at 20°C).
• Thermal performance and endurance: Operating temperature range -25°C to +105°C with endurance specified for 2000 hours at 105°C under rated ripple and DC bias.
• Safety and reliability: Improved safety features for abnormally excessive voltage and a pressure relief vent design to mitigate hazardous failure modes.
• Package and mounting: Snap-in radial can (φ30 × 25 mm length) for secure panel or chassis mounting; supplied in tray packing and currently in mass production.
• Environmental compliance: RoHS compliant per the series documentation.

Typical Applications

• General Purpose – Bulk energy storage and filtering in general-purpose power circuits where a 450 V rated capacitor is required.
• Voltage-fluctuating equipment – Designed for equipment used in areas with fluctuating supply voltages thanks to improved abnormal-voltage safety features.
• High-temperature designs – Suited for applications that require long-term operation at elevated temperatures up to 105°C, supported by a 2000-hour endurance rating at 105°C.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage power supplies and converter stages.
• Robust ripple handling: Specified ripple current values at both low and high frequencies provide predictable thermal and lifetime behavior under AC stress.
• Long high-temperature lifetime: 2000 hours endurance at 105°C supports reliable operation in thermally demanding environments.
• Safety-focused design: Pressure relief vent and improved abnormal-voltage tolerance reduce the risk of hazardous failures under stress conditions.
• Compact snap-in package: φ30 × 25 mm radial can with snap-in terminals offers a secure mechanical mounting option in space-constrained designs.
• Regulatory compliance: RoHS compliance aligns with environmental requirements for many industrial and commercial products.
