LAS2W101MELZ30ZB

The LAS2W101MELZ30ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAS series designed for high-voltage, high-ripple applications. It delivers 100 µF at 450 V in a smaller-sized radial can with snap-in mounting, optimized for equipment operating in environments with fluctuating voltages.

Key value comes from its 105°C endurance rating with 2,000 hours of rated ripple-current life, improved safety features for abnormal over-voltage conditions, and RoHS compliance for regulatory consistency.

Key Features

• High voltage and capacitance: 100 µF nominal capacitance rated at 450 V for high-voltage DC smoothing and filtering tasks.
• 105°C endurance: Rated to operate from −25°C to +105°C and specified to withstand 2,000 hours of D.C. bias plus rated ripple current at 105°C with defined limits for capacitance change, tan δ and leakage current.
• Strong ripple performance: Rated ripple current of 710 mA at 120 Hz and 816.5 mA at 10 kHz, with frequency coefficients specified (1.00 at 120 Hz, 1.15 at 10 kHz) for reliable thermal performance across frequency.
• Snap-in radial can package: Radial, can-type snap-in terminals provide secure board mounting for power assemblies and ease of installation in PCB designs.
• Improved safety features: Pressure relief venting and safety performance are specified to operate without dangerous conditions under abnormal excessive voltage, per the LAS series safety tests.
• RoHS compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory and environmental requirements.
• Compact footprint: Smaller case sizes and higher ripple current capability compared with the LAQ series; physical dimensions include approximately L: 3.0 cm × D: 2.2 cm and a seated height up to 1.181 inches.

Typical Applications

• General-purpose power filtering: Bulk and smoothing capacitors in power supply circuits where 450 V working voltage and high ripple handling are required.
• Equipment exposed to fluctuating voltages: Systems operating under variable or unstable input conditions, where improved safety features and endurance at 105°C are important.
• Industrial power systems: Power electronics and control equipment that demand durable, high-voltage capacitors with secure snap-in mounting for reliable board retention.

Unique Advantages

• High-voltage, high-ripple capability: 100 µF at 450 V with specified ripple currents supports demanding filtering applications without overspecifying component count.
• Long 105°C rated life: 2,000 hours endurance at 105°C under rated ripple current gives predictable aging characteristics for thermal-stressed designs.
• Safety-focused construction: Improved safety features and pressure-relief venting reduce the risk of hazardous failure under abnormal voltage conditions.
• Secure snap-in mounting: Radial snap-in terminals provide robust mechanical retention for heavy-current and vibration-prone environments.
• Compact, higher-performance alternative: Smaller case size with higher ripple current than the LAQ series enables space-efficient board layouts without sacrificing thermal performance.
• Regulatory readiness: RoHS compliance simplifies integration into designs with environmental and substance restrictions.
