LLG2Z122MELZ45

The LLG2Z122MELZ45 is a Nichicon LLG series snap-in aluminum electrolytic capacitor offering 1200 µF capacitance at a 180 V rating in a compact, snap-in can package. It is designed for general-purpose power applications where a high-voltage, high-capacitance, snap-in solution is required.

With an operating temperature range of –40°C to +85°C, a 2000-hour endurance at 85°C, and RoHS compliance, this part supports equipment downsizing while delivering robust ripple-handling and stable performance under DC bias.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with a rated voltage of 180 V and tolerance of −20% to +20% for power filtering and energy storage in high-voltage rails.
• Snap-in Radial Can — Snap-in terminal type and radial can package for secure board mounting and simplified assembly in power supply and industrial PCBs.
• Compact Size — Smaller-sized LLG series case (φ22 × 45 mm) suitable for equipment downsizing while maintaining high capacitance.
• Ripple Current Capability — Low-frequency ripple current 2.9 A (120 Hz) and high-frequency ripple current 4.35 A (100 kHz) to support a range of switching and line-frequency power conditions.
• Leakage and Dissipation — Specified leakage current of 1390 µA and tangent of loss angle (tan δ) max. 0.15 measured at 20°C, 120 Hz, enabling predictable loss and leakage behavior.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C with performance recovery after DC bias plus rated ripple current; operating range from −40°C to +85°C.
• Regulatory — Compliant with RoHS directive as stated for the LLG series.
• Packaging & Availability — Tray packing; product status: mass production.

Typical Applications

• Power Supplies — Bulk smoothing and energy storage on high-voltage rails where 180 V rating and high capacitance are required.
• Industrial Equipment — Filtering and decoupling in industrial inverters and control systems that operate across –40°C to +85°C.
• PFC and DC Link Circuits — Ripple handling for power-factor-correction stages and DC link capacitors thanks to specified low- and high-frequency ripple current ratings.

Unique Advantages

• High-Voltage, High-Capacity Combination: Provides 1200 µF at 180 V in a single component, reducing BOM count for high-voltage energy storage.
• Compact Snap-In Form Factor: φ22 × 45 mm snap-in can helps reduce PCB footprint and supports reliable mechanical retention in through-hole assemblies.
• Designed for Down-Sized Designs: LLG series is one rank smaller than LLS, enabling smaller case choices without sacrificing capacitance.
• Measurable Performance Metrics: Specified tan δ (0.15 at 20°C, 120 Hz), leakage current (1390 µA), and ripple currents (2.9 A / 4.35 A) allow predictable design margins for thermal and ripple considerations.
• Long Endurance at Elevated Temperature: 2000 hours at 85°C under rated conditions provides a defined reliability baseline for thermal-stressed applications.
• RoHS Compliant: Meets RoHS requirements as indicated for the LLG series, supporting regulatory compliance in product builds.
