LAS2G820MELZ25ZB

The LAS2G820MELZ25ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LAS series, designed for large-can, high-voltage applications. It provides 82 µF capacitance at a 400 V rating with construction optimized for snap-in mounting and radial can packaging.

Engineered for general-purpose use and equipment exposed to fluctuating voltages, this capacitor combines high ripple-current capability and extended endurance at elevated temperatures to support demanding power-electronic environments.

Key Features

• Electrical Performance — 82 µF capacitance with a voltage rating of 400 V and tolerance of -20% to +20% to meet design margins.
• High Ripple-Current Handling — Rated low-frequency ripple current of 640 mA at 120 Hz and high-frequency ripple current of 736 mA at 10 kHz to support AC ripple filtering and DC-link decoupling under load.
• Loss and Leakage Characteristics — Maximum tanδ of 0.20 (measured at 20°C, 120 Hz) and specified leakage current of 540 µA for predictable loss and standby behavior.
• Thermal Endurance — Rated for operation from -25°C to +105°C with an endurance of 2000 hours at 105°C under rated ripple conditions.
• Safety and Reliability — Snap-in large-can construction with pressure relief vent and improved safety features for abnormal voltage conditions; designed to withstand prolonged application of rated ripple current at 105°C.
• Compact Snap-in Package — Radial, can-style snap-in mounting in a compact φ22 × 25 mm (D × L) footprint for robust PCB attachment and simplified assembly.
• RoHS Compliant — Meets RoHS directive requirements for environmentally compliant designs.

Typical Applications

• General-purpose circuits — For designs that require a 400 V rated electrolytic capacitor with moderate capacitance and controlled tolerance for routine power tasks.
• Voltage-fluctuating equipment — Suited for systems operating in environments with variable supply conditions thanks to safety features for abnormal voltage and ripple endurance at 105°C.
• High-ripple power stages — Appropriate where elevated ripple-current capability at both low and high frequencies is needed to maintain stability under dynamic load.

Unique Advantages

• 400 V rating with substantial capacitance: Supports elevated DC-voltage designs while providing 82 µF of energy storage per unit for compact system layouts.
• Dual-frequency ripple capability: Specifies ripple performance at 120 Hz and 10 kHz (640 mA and 736 mA respectively), enabling predictable behavior across typical power-system bandwidths.
• High-temperature endurance: 2000-hour life at 105°C ensures continued performance in thermally demanding installations.
• Robust safety features: Pressure relief vent and enhanced protection against abnormal voltage conditions improve system-level reliability and serviceability.
• Space-efficient snap-in form factor: Radial can snap-in package (φ22 × 25 mm) simplifies mounting for panel- and chassis-style power assemblies.
• Regulatory compliance: RoHS compliance supports environmentally conscious product designs and supply-chain requirements.
