LAK2G470MELB20ZB

The LAK2G470MELB20ZB is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose high-voltage applications. It provides 47 µF capacitance at a 400 V rating with polarized construction suited for DC filtering and energy storage in equipment exposed to fluctuating voltages.

Built for durability, this part is specified for 2000 hours of endurance at 105°C and includes safety features for abnormally excessive voltage, making it appropriate where high-temperature endurance and controlled electrical performance are required.

Key Features

• Capacitance & Voltage: 47 µF rated capacitance at 400 V for high-voltage DC filtering and smoothing tasks.
• High-temperature Endurance: Specified lifetime of 2000 hours at 105°C to support continuous operation in elevated temperature environments.
• Ripple Current Performance: 400 mA at 120 Hz (low frequency) and 460 mA at 10 kHz (high frequency) for handling AC ripple in power circuits.
• Electrical Stability: Maximum tan δ of 0.20 and leakage current specified at 410 µA for predictable loss and leakage characteristics.
• Package & Mounting: Snap-in, radial can package (φ30 × 20 mm) for secure, board-mounted power applications.
• Operating Range & Polarization: Polarized capacitor rated for operation from −25°C to +105°C.
• Safety & Compliance: Designed with pressure-relief venting for safety in abnormal voltage conditions and compliant with RoHS requirements.

Typical Applications

• Voltage-fluctuating equipment: Bulk smoothing and energy buffering where supply voltages vary, leveraging the part’s 400 V rating and safety features.
• Power supply filtering: DC link filtering and ripple suppression using the specified 400 mA (120 Hz) and 460 mA (10 kHz) ripple current capabilities.
• High-temperature installations: Applications requiring sustained operation at elevated temperatures, supported by 2000 hours endurance at 105°C.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC circuits without requiring multiple components in series.
• Designed for long-term elevated-temperature operation: 2000 hours at 105°C specification supports reliable performance under thermal stress.
• Robust ripple handling: Defined low- and high-frequency ripple current ratings provide a clear basis for thermal and lifetime calculations in power designs.
• Safety-oriented design: Pressure-relief venting and abnormal-voltage safety considerations reduce risk in voltage-transient environments.
• Install-ready snap-in package: Radial snap-in can (φ30 × 20 mm) simplifies secure mounting in power assemblies.
• Regulatory compliance: RoHS compliance supports use in regulated product lines.
