LAS2W121MELZ35

The LAS2W121MELZ35 is a Nichicon LAS series aluminum electrolytic capacitor in a snap‑in terminal, radial can package. It delivers 120 µF capacitance at a 450 V rating with polarized construction and is designed for general‑purpose use in equipment that requires high‑voltage energy storage and ripple handling.

Engineered for high operating temperature and durability, this part is rated to 105°C with 2000 hours endurance under rated ripple current, and is supplied in tray packing for mass production assembly.

Key Features

• Electrical Performance: 120 µF capacitance at 450 V rated voltage with ±20% tolerance; polarized design suitable for high‑voltage DC applications.
• High‑Temperature Endurance: Rated for operation from −25°C to +105°C and qualified for 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability: Rated ripple current of 770 mA at 120 Hz and 885.5 mA at 10 kHz, with frequency coefficients provided for higher frequencies.
• Safety Features: Built‑in pressure relief vent for controlled operation under abnormal voltage conditions to avoid dangerous failures.
• Compact Snap‑In Package: Radial, can‑snap‑in mounting for secure PCB retention; physical size L: 3.5 cm × D: 2.2 cm (approximately 35 mm × 22 mm).
• Regulatory Compliance: RoHS compliant per the datasheet specification.

Typical Applications

• Power Supplies: General‑purpose DC link and filtering where 450 V rating and high ripple current capability are needed for smoothing and energy buffering.
• Industrial Equipment: Use in equipment exposed to voltage fluctuations—series guidance identifies this family as suited to voltage‑fluctuating environments.
• Inverters and UPS Systems: Energy storage and ripple mitigation in higher‑voltage inverters and uninterruptible power systems requiring long‑life capacitors.

Unique Advantages

• Long Endurance at Elevated Temperature: Specified for 2000 hours at 105°C under rated ripple current, supporting longer service life in hot operating environments.
• Designed for Abnormal Voltage Conditions: Improved safety features and a pressure relief vent reduce the risk of dangerous failures under excessive voltage events.
• High Voltage, Compact Size: 450 V rating combined with a 22 mm diameter and 35 mm length offers high‑voltage capability in a smaller case footprint.
• High Ripple Current for Its Size: Higher ripple current capability than previous LAS series references, enabling effective filtering in compact designs.
• Production‑Ready Packaging: Supplied in tray packing to support mass production and streamlined assembly processes.
• RoHS Compliance: Meets RoHS requirements, assisting designs that target regulated markets.
