LLS2Z122MELB

The LLS2Z122MELB is an aluminum electrolytic, snap-in terminal capacitor rated for 180 V with a nominal capacitance of 1200 µF. It is a snap-in, radial can type designed for general-purpose power circuitry and industrial applications where robust ripple handling and long endurance at elevated temperatures are required.

Key performance attributes include an 85°C category temperature rating, specified ripple current capability at both low and high frequencies, a 3000-hour endurance rating at 85°C, and RoHS compliance. The part is supplied in tray packing and is in mass production.

Key Features

• Capacitance & Tolerance — 1200 µF with ±20% tolerance at 120 Hz and 20°C.
• Voltage & Temperature Rating — Rated for 180 V; operating temperature range −40°C to +85°C.
• High Ripple Current Capability — 3550 mA at 120 Hz (low frequency) and 5325 mA at 50 kHz (high frequency), enabling steady performance under AC ripple stress.
• Endurance — Designed to withstand 3000 hours of DC bias plus rated ripple current at 85°C with specified limits on capacitance change, dissipation factor, and leakage current.
• Dissipation & Leakage — Dissipation factor (tan δ) of 0.15 maximum at 20°C and 120 Hz; leakage current specified at 1390 µA.
• Package & Mounting — Snap-in radial can construction, physical size φ30 × 35 mm (L: 3.5 × D: 3 cm), supplied in tray packing for production assembly.
• Environmental Compliance — Compliant with RoHS requirements.

Typical Applications

• General Purpose Power Circuits — Intended for general-purpose use where a 180 V, 1200 µF snap-in capacitor is required.
• Industrial Power Supplies — Suited to power-supply designs that require sustained ripple handling and long endurance at elevated temperatures.
• Bulk Energy Storage — Provides bulk capacitance in systems that need stable capacitance and controlled dissipation over long operating periods.

Unique Advantages

• High ripple current capacity — Specified ripple current values at both 120 Hz and 50 kHz support designs with significant AC ripple stress.
• Long endurance at elevated temperature — 3000-hour rated life at 85°C under rated ripple current improves reliability in continuous-duty environments.
• Controlled dissipation — tan δ of 0.15 at 20°C/120 Hz provides predictable loss characteristics for thermal and performance planning.
• Clear leakage specification — Defined leakage current (1390 µA) aids in power-loss and hold-up time calculations.
• Production-ready packaging — Tray packing and mass-production availability simplify procurement and assembly planning.
• Regulatory compliance — RoHS compliance supports deployment in regulated markets.
