LAS2W121MELA30

The LAS2W121MELA30 is a Nichicon LAS series aluminum electrolytic capacitor in a snap-in terminal (radial can) package, offering 120 µF capacitance at a 450 V rating with ±20% tolerance. Engineered for general-purpose power applications, it provides high-voltage bulk capacitance with a compact φ25 × 30 mm case and snap-in mounting for secure board retention.

Designed for robust performance in fluctuating-voltage environments, this part delivers specified ripple capability, long endurance at elevated temperature, and safety features documented for the LAS series.

Key Features

• High voltage rating: 450 V rated voltage suitable for applications requiring high DC link or bulk capacitance in general-purpose equipment.
• Capacitance and tolerance: 120 µF with ±20% tolerance measured at 120 Hz, 20°C, providing defined bulk energy storage for smoothing and filtering.
• Snap-in radial can package: φ25 × 30 mm compact can with snap-in terminals for reliable mechanical retention and straightforward mounting.
• Ripple current capability: Rated ripple current of 760 mA at 120 Hz (low frequency) and 874 mA at 10 kHz (high frequency), with frequency coefficients available to scale ripple ratings across frequency.
• Endurance at elevated temperature: Specified for 2000 hours at 105°C when D.C. bias plus rated ripple current is applied, with defined limits for capacitance, tan δ and leakage after the test.
• Controlled dissipation factor and leakage: tan δ ≤ 0.20 (120 Hz, 20°C) and leakage current specified (690 µA for this part), enabling predictable loss and standby behavior.
• Safety features: LAS series includes pressure relief vent characteristics and improved safety performance for abnormally excessive voltage per the datasheet specifications.
• Environmental compliance and production: RoHS compliant and available in tray packing for mass production use.

Typical Applications

• General-purpose power supplies: Bulk smoothing and filtering in equipment where a 450 V rated capacitor and defined ripple capability are required.
• Equipment in voltage-fluctuating environments: Designed and noted in the LAS series datasheet as suited for devices exposed to fluctuating voltages, leveraging improved safety features.
• Industrial and commercial electronics: Use where compact high-voltage capacitance, snap-in mounting, and specified endurance at 105°C are needed for reliable operation.

Unique Advantages

• High-voltage bulk energy: 450 V rating combined with 120 µF capacitance provides substantial stored energy for DC link and smoothing roles.
• Measured ripple performance: Published ripple currents at 120 Hz and 10 kHz (760 mA and 874 mA respectively) and frequency coefficients allow designers to size thermal and ripple margins accurately.
• Durability at 105°C: 2000-hour endurance specification under rated conditions gives a clear reliability target for high-temperature applications.
• Compact snap-in form factor: φ25 × 30 mm case and snap-in terminals save PCB area while providing secure mechanical mounting for mass-production assembly.
• Predictable electrical characteristics: Specified tan δ, leakage current, and tolerance values support deterministic design for filtering and timing functions.
• Safety-minded design: LAS series safety performance and pressure relief vent operation reduce risk in abnormal over-voltage events.
