LLS2G181MELZ

The LLS2G181MELZ is a Nichicon LLS series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It delivers 180 µF capacitance at a 400 V rating with polarized construction and tray packing suitable for production assembly.

Designed for general-purpose applications, this part provides long-life endurance (3,000 hours at 85°C under rated ripple current), measurable low-frequency and high-frequency ripple handling, and RoHS compliance for regulated production environments.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance rated at 400 V to support high-voltage energy storage and smoothing where a polarized electrolytic is required.
• Snap-in Terminal / Package — Radial, can-type snap-in mounting for secure chassis or board retention and reliable mechanical connection in high-current applications.
• Endurance at Elevated Temperature — Specified to withstand 3,000 hours of rated ripple current at 85°C, meeting series endurance requirements for sustained operation.
• Ripple Current Performance — 1,410 mA at 120 Hz (low frequency) and 2,016.3 mA at 50 kHz (high frequency) to handle both mains-frequency and high-frequency ripple conditions.
• Loss & Leakage — Specified tan δ (DF) of 0.15 at 20°C and 120 Hz and a maximum leakage current of 800 µA, supporting predictable loss characteristics and low standby leakage.
• Operating Range & Tolerance — Operating temperature range of −25°C to +85°C with capacitance tolerance of ±20% for predictable behavior across the specified environment.
• Form Factor & Packing — Compact φ22 × 40 mm body (L: 4.0 cm × D: 2.2 cm) supplied in tray packing and available in mass production quantities.
• Regulatory Compliance — RoHS compliant for use in regulated manufacturing environments.

Typical Applications

• General-purpose power systems — For circuits requiring 400 V rated capacitance in a snap-in, can-style package for bulk energy storage and filtering in general-purpose designs.
• High-voltage assemblies — Where 400 V dielectric rating and polarized electrolytic performance are needed within the specified −25°C to +85°C operating range.
• Production-ready modules — Tray-packed and offered in mass production, suitable for manufacturing processes that use snap-in capacitors for mechanical retention and assembly throughput.

Unique Advantages

• Long-term endurance: Rated for 3,000 hours at 85°C with rated ripple current applied, enabling predictable life under sustained thermal and electrical stress.
• Dual-frequency ripple capability: Clear low-frequency (1.41 A at 120 Hz) and high-frequency (2.0163 A at 50 kHz) ripple current specifications to support a range of ripple environments.
• Low loss and controlled leakage: Specified tan δ and 800 µA leakage provide predictable dissipation and standby current characteristics for system design.
• Production-friendly packaging: Tray packing and mass production availability help streamline procurement and assembly for volume manufacturing.
• Compact high-voltage form factor: φ22 × 40 mm can-style body balances high-voltage capability with a compact footprint for constrained assemblies.
• Regulatory readiness: RoHS compliance supports deployment in regulated supply chains without additional material qualification steps.
