LAS2W101MELA25

The LAS2W101MELA25 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 100 µF at 450 V with polarized construction and is optimized for use where voltage can fluctuate or where higher ripple handling at elevated temperatures is required.

Built for high-temperature operation, the capacitor is rated for -25 °C to +105 °C and is specified to withstand 2,000 hours of rated ripple current at 105 °C, providing long-duration stability in demanding environments.

Key Features

• High voltage rating (450 V): Rated for 450 V DC, suitable for high-voltage power circuits requiring durable energy storage.
• 100 µF capacitance with ±20% tolerance: Precision capacitance for bulk smoothing and decoupling in power sections where a polarized electrolytic is appropriate.
• 105 °C endurance: Specified endurance of 2,000 hours with rated ripple current applied at 105 °C, supporting extended operation at elevated temperatures.
• Elevated ripple current capability: Rated ripple current of 710 mA at 120 Hz and 816.5 mA at 10 kHz, enabling effective ripple absorption across low- and high-frequency domains.
• Snap-in mounting: Radial, can-style snap-in package for secure chassis or board mounting in power assemblies.
• Improved safety features: Designed with safety performance and a pressure relief vent to operate without flames, ignition, or dangerous case dispersion under abnormal voltage conditions.
• RoHS compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• General-purpose power smoothing: Bulk filtering and voltage stabilization in power supply sections where polarized electrolytics are used.
• Equipment in voltage-fluctuating areas: Intended for equipment exposed to line-voltage variation, leveraging improved safety features and endurance at 105 °C.
• High-temperature power systems: Energy storage and ripple absorption where operation up to 105 °C and multi-hour endurance are required.
• Secure chassis or board mounting: Snap-in terminal design for installations that benefit from robust mechanical retention.

Unique Advantages

• High-temperature reliability: 2,000-hour rated endurance at 105 °C ensures consistent performance under sustained thermal stress.
• Strong ripple performance across frequencies: Specified ripple currents at 120 Hz and 10 kHz support both mains-frequency and higher-frequency ripple suppression.
• Compact, higher-ripple alternative: Smaller case size with higher ripple capability compared to earlier series, enabling space-efficient power designs.
• Safety-focused construction: Pressure relief vent and improved safety measures reduce risk during abnormal over-voltage events.
• Regulatory compliance: RoHS compliance simplifies selection for designs that must meet restricted-substance requirements.
