LLS2G181MELB

The LLS2G181MELB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose applications requiring a high-voltage, high-capacitance solution. It pairs a 180 µF capacitance with a 400 V rating in a compact radial can (φ30 × 25 mm) and is offered in tray packing for production-level use.

Key performance attributes include a 3000-hour endurance at 85°C under rated ripple conditions, specified ripple current capability at both low and high frequencies, low leakage, and RoHS compliance—making it suitable where long-term electrical reliability at elevated temperature is required.

Key Features

• High Voltage, High Capacitance — 180 µF nominal capacitance at a 400 V rated voltage for bulk energy storage and DC link applications requiring elevated voltage capability.
• Snap-In Radial Can — Snap-in terminal mounting and radial can package (φ30 × 25 mm) optimized for secure PCB retention and high-current assemblies.
• Endurance at Elevated Temperature — Rated for 3000 hours at 85°C with DC bias plus rated ripple current applied, meeting the series’ endurance criteria for capacitance, tan δ and leakage current.
• Ripple Current Capability — 1.52 A ripple current at 120 Hz and 2.174 A ripple current at 50 kHz to support both low- and high-frequency ripple environments.
• Electrical Loss and Leakage — Specified tan δ of 0.15 (20°C, 120 Hz) and a typical leakage current of 800 µA for predictable dissipation and low self-discharge.
• Operating Range and Tolerance — Polarized capacitor with an operating temperature range of −25°C to +85°C and capacitance tolerance of ±20%.
• Compliance and Production — RoHS-compliant construction and available in tray packing for mass production deployments.

Typical Applications

• General-Purpose Power Modules — Suited for applications that require a 400 V, 180 µF snap-in electrolytic capacitor with defined ripple and endurance characteristics.
• Industrial Electronics — Intended for use in assemblies where long-term operation at up to 85°C and stable electrical behavior are required.
• High-Voltage DC Storage — Applicable where compact high-voltage capacitance and snap-in mounting are preferred for board-level installation.

Unique Advantages

• High DC Voltage Capability: 400 V rating enables use in higher-voltage circuits without series stacking.
• Verified Endurance: 3000-hour life at 85°C under rated ripple current provides measurable longevity for sustained thermal stress conditions.
• Dual-Frequency Ripple Support: Specified ripple current at 120 Hz and 50 kHz supports both mains-frequency and higher-frequency switching environments.
• Low Dielectric Loss: tan δ of 0.15 at 20°C/120 Hz yields predictable dissipation characteristics for thermal management planning.
• Compact Snap-In Form Factor: φ30 × 25 mm radial can with snap-in terminals simplifies PCB installation and secure mechanical retention.
• Production-Ready Packaging: Tray packing and mass production status streamline procurement and assembly for volume manufacturing.
