LLS2W181MELB

The LLS2W181MELB is a snap-in terminal aluminum electrolytic capacitor rated at 450 V with 180 µF capacitance and ±20% tolerance. Designed as a general-purpose, high-voltage power component, it provides robust ripple handling and long endurance for demanding power-electronics applications.

Key value comes from its high-voltage 450 V rating combined with rated ripple currents up to 1.45 A (120 Hz) and 2.07 A (50 kHz), a 3000 h endurance at 85°C, RoHS compliance, and tray packing for production-ready deployment.

Key Features

• High Voltage & Capacitance — 450 V rated voltage with 180 µF capacitance (±20%) for high-voltage energy storage and filtering.
• Snap‑in Terminal Package — Radial, can-style snap-in mounting simplifies board assembly for power modules and chassis-mounted designs.
• Endurance at Elevated Temperature — Rated for 3000 hours at 85°C under DC bias plus rated ripple current, supporting reliable long-term operation.
• High Ripple Current Capability — 1.45 A at 120 Hz (low frequency) and 2.07 A at 50 kHz (high frequency) to support smoothing and DC-link applications.
• Loss and Leakage Characteristics — tan δ of 0.2 (max) at 20°C, 120 Hz and specified leakage current of 850 µA for predictable performance in AC and DC environments.
• Operating Range & Polarization — Polarized device with an operating temperature range of −25°C to +85°C for general-purpose power equipment.
• Production‑Ready Packaging — Tray packing and mass production status for manufacturing-scale procurement and assembly.
• RoHS Compliant — Meets RoHS requirements for restricted substances in electronic equipment.

Typical Applications

• Power filtering and smoothing — Suited for high-voltage smoothing where 180 µF at 450 V and strong ripple handling are required.
• DC-link capacitors in converters — Provides energy buffering and ripple attenuation in AC/DC and DC/DC converter stages using its rated ripple-current capability.
• Industrial power electronics — General-purpose use in industrial control and power modules that operate within −25°C to +85°C and require long endurance.
• Chassis-mounted power supplies — Snap-in radial package for secure mounting in power supply assemblies and other rugged enclosures.

Unique Advantages

• High-voltage capacity: 450 V rating with 180 µF provides substantial stored energy for high-voltage power rails.
• Robust ripple handling: Rated ripple currents of 1.45 A (120 Hz) and 2.07 A (50 kHz) reduce thermal stress and support stable filtering under varying load frequencies.
• Long endurance at temperature: 3000 hours at 85°C under rated conditions supports sustained reliability in continuous-duty applications.
• Predictable electrical loss and leakage: Specified tan δ and leakage current values enable reliable margining and thermal design.
• Manufacturing-ready form factor: Snap-in can package and tray packing simplify assembly workflows for production volumes.
• Regulatory compliance: RoHS compliance helps meet environmental requirements for commercial and industrial electronics.
