LAK2G330MELZ20

The LAK2G330MELZ20 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 33 µF capacitance at a 400 V rating in a compact 22 × 20 mm radial can, offering a balance of voltage handling and size for power rails and systems exposed to fluctuating voltages.

Built for robust operation, this capacitor is specified for -25°C to +105°C and is rated to withstand 2000 hours of DC bias plus rated ripple current at 105°C, making it suitable for equipment requiring stable performance under elevated-temperature and variable-voltage conditions.

Key Features

• Capacitance & Voltage: 33 µF capacitance at 400 V DC for high-voltage filtering and energy decoupling in compact assemblies.
• Snap-in Radial Package: Snap-in terminal, radial can package (22 × 20 mm) for secure board mounting and simplified assembly.
• High-Temperature Endurance: Specified for 2000 hours of D.C. bias plus rated ripple current at 105°C; capacitance change remains within ±20% after endurance.
• Temperature Range: Operates from -25°C to +105°C to cover a wide range of industrial and general-purpose environments.
• Loss Characteristics: Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C, supporting predictable AC performance.
• Ripple Current Capability: Rated ripple current of 220 mA at 120 Hz and 253 mA at 10 kHz for effective smoothing under AC ripple conditions.
• Safety Features: Pressure relief venting and improved safety measures for abnormally excessive voltage to reduce hazardous failure modes.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Power supply filtering: Smoothing and decoupling on high-voltage DC rails where 400 V rating and defined ripple current capability are required.
• Industrial equipment: Use in general-purpose industrial systems that encounter voltage fluctuations and elevated operating temperatures.
• Bulk smoothing on PCBs: Snap-in mounting provides secure attachment for board-level bulk capacitance in power assemblies.

Unique Advantages

• High-voltage capability: 400 V rating enables use on higher-voltage DC rails without upsizing the capacitor.
• Compact, serviceable package: 22 × 20 mm snap-in radial can balances board space and mechanical stability for assembly.
• Proven high-temperature life: Endurance tested to 2000 hours at 105°C under rated ripple current, with capacitance retention within specified limits—supporting reliability in hot environments.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz provide clear guidance for thermal and ripple-management design decisions.
• Safety-minded design: Pressure relief venting and improved abnormal-voltage protections reduce the risk of dangerous failure modes in stressed applications.
• Regulatory compliance: RoHS compliance simplifies use in designs targeting restricted-substance requirements.
