LAS2W151MELA35

The LAS2W151MELA35 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications requiring high voltage capability and robust thermal endurance. It combines a 150 µF capacitance with a 450 V rating in a compact radial can (φ25×35L) snap-in package suitable for board-level bulk energy storage and filtering.

Key value drivers include a 105°C permissible operating temperature with 2000 hours endurance, high ripple-handling capability across low and high frequencies, and RoHS compliance—making it well suited to industrial and power-conversion environments where voltage fluctuation tolerance and long service life are important.

Key Features

• High Voltage Rating — 450 V rated voltage for demanding power supply and high-voltage filtering applications.
• Capacitance and Tolerance — 150 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable bulk storage and decoupling.
• Thermal Endurance — Rated to operate from −25°C to +105°C with a 2000 h endurance specification at 105°C under rated ripple conditions.
• Low Loss (tan δ) — Maximum tan δ of 0.20 at 20°C and 120 Hz, supporting efficient energy transfer and reduced heating under AC ripple.
• High Ripple Current Capability — 880 mA at 120 Hz (low frequency) and 1.012 A at 10 kHz (high frequency) to handle significant AC components in power circuits.
• Leakage Current — Specified leakage current of 770 µA, providing predictable DC leakage characteristics for power designs.
• Snap-in Radial Package — φ25×35L radial can with snap-in terminals for secure board mounting and streamlined assembly; supplied in tray packing for mass production.
• RoHS Compliant — Meets applicable RoHS requirements for environmental compliance.

Typical Applications

• Power Supplies: Bulk energy storage and output filtering in high-voltage AC/DC and DC/DC converters where 450 V rating and high ripple current are required.
• Industrial Power Electronics: Smoothing and decoupling in industrial motor drives, inverter circuits, and power conversion equipment operating up to 105°C.
• Uninterruptible Power Supplies (UPS) and Energy Backup: Bulk capacitance for hold-up and filtering functions in systems exposed to fluctuating input voltages.
• Test & Measurement Equipment: High-voltage filtering and energy storage in laboratory and bench instruments that benefit from a compact snap-in form factor.

Unique Advantages

• Robust high-voltage capability: 450 V rating enables use in higher-voltage power rails without up-rating components.
• Designed for sustained thermal stress: 2000 h endurance at 105°C ensures longer reliable operation in hot operating environments.
• Broad ripple performance: Specified ripple current at both 120 Hz and 10 kHz supports effective filtering across low- and high-frequency components.
• Compact snap-in packaging: φ25×35L radial can with snap-in terminals reduces board footprint while providing secure mechanical mounting for high-current applications.
• Predictable electrical behavior: Specified tan δ and leakage current values allow engineers to model heating, losses, and leakage for precise system design.
• Production-ready supply: Tray packing and mass production availability support volume assembly and procurement workflows.
