LLS2V181MELA

The LLS2V181MELA is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications that require a high-voltage capacitor in a compact radial can. It provides 180 µF capacitance at a 350 V rating with snap-in mounting, offering a combination of voltage handling, ripple capability and long endurance suitable for production assemblies.

Engineered for continuous operation up to 85°C, this part supports high-frequency and low-frequency ripple current duty while maintaining low leakage and stable electrical characteristics over a 3000-hour endurance period at 85°C.

Key Features

• Rated capacitance and tolerance — 180 µF with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable energy storage for high-voltage circuits.
• High voltage rating — 350 V DC rating suitable where elevated voltage handling is required.
• Snap-in radial can package — φ25 × 25 mm radial can with snap-in terminals for secure mounting and straightforward assembly in production environments.
• Ripple current capability — 1.370 A at 120 Hz (low frequency) and 1.9591 A at 50 kHz (high frequency), enabling stable operation under AC ripple conditions.
• Low leakage and dissipation — leakage current specified at 750 µA and tan δ of 0.15, supporting reliable performance in DC bias applications.
• Endurance and temperature range — rated for 3000 hours at 85°C and an operating temperature range of −25°C to +85°C for the 350 V class.
• RoHS compliant — meets RoHS requirements for environmental compliance.
• Production-friendly packing — tray packing and mass production availability for volume assembly needs.

Typical Applications

• General-purpose high-voltage systems — for designs that require a 350 V, 180 µF capacitor with significant ripple-current handling and long endurance.
• Industrial and commercial equipment — suitable where a durable polarized snap-in capacitor with 3000-hour endurance at 85°C is required.
• High-frequency ripple environments — applicable in circuits that experience both low-frequency (120 Hz) and high-frequency (50 kHz) ripple currents up to the specified limits.

Unique Advantages

• High-voltage energy storage: 350 V rating combined with 180 µF capacitance supports applications demanding elevated DC voltage capability.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 50 kHz let designers account for AC stress across a range of operating frequencies.
• Long endurance at elevated temperature: 3000 hours at 85°C ensures predictable life performance under sustained thermal and electrical load.
• Low leakage and controlled dissipation: 750 µA leakage and tan δ of 0.15 contribute to stable DC behavior and manageable losses.
• Production-ready packaging: Tray-packed, snap-in radial can simplifies automated assembly and replacement in production lines.
• Regulatory compliance: RoHS compliance supports deployment in environments requiring restricted-substance conformance.
