LLS2Z561MELZ

The LLS2Z561MELZ from Nichicon is a snap-in terminal type aluminum electrolytic capacitor in the LLS series. It is a polarized, radial can capacitor rated for 180 V and 560 µF, designed for general-purpose power applications that require robust ripple handling and long-term performance at elevated ambient temperatures.

Key value propositions include a 3000-hour rated endurance under ripple at 85°C, RoHS compliance, and a snap-in mounting style that supports secure, through-hole installation in power assemblies.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a rated voltage of 180 V and a tolerance of ±20% (–20% to +20%) measured at 120 Hz, 20°C.
• Endurance at Elevated Temperature — Rated to withstand 3000 hours of D.C. bias plus rated ripple current at 85°C, with capacitance change within ±20% after the test.
• Ripple Current Capability — Rated ripple current of 2.25 A at 120 Hz and 3.375 A at 50 kHz to support high-ripple power environments.
• Operating Temperature Range — Specified for –40°C to +85°C operation for rated voltages in the applicable range.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes' application of rated voltage at 20°C, enabling predictable bias behavior.
• Package & Mounting — Radial, snap-in can package (snap-in terminal type) for reliable through-hole mounting and robust mechanical retention.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power supply filtering — Polarized aluminum electrolytic capacitor with snap-in terminals for stable bulk capacitance and ripple handling in power supply assemblies.
• DC link and smoothing — High-capacitance, high-voltage rating suitable for smoothing and energy-storage roles where 180 V and 560 µF are required.
• Industrial power modules — Radial can snap-in construction supports secure through-hole installation in industrial and commercial power converter assemblies.

Unique Advantages

• Long endurance under ripple: 3000 hours at 85°C under rated ripple current provides predictable lifetime performance for sustained high-temperature applications.
• Defined ripple current performance: Specified ripple currents at both 120 Hz and 50 kHz allow designers to select the capacitor with known AC stress capability.
• Through-hole, snap-in reliability: Snap-in terminals and radial can packaging offer mechanical stability and straightforward PCB assembly for power hardware.
• Clear electrical limits: Leakage current and tan δ are specified in the datasheet (tan δ max. 0.15 for 180 V rating), enabling direct verification against design requirements.
• RoHS compliant: Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances.
