LAK2G151MELA35ZB

The LAK2G151MELA35ZB is a snap-in terminal aluminum electrolytic capacitor in Nichicon's LAK series, specified at 150 µF and 400 V. It is a polarized, radial can (snap-in) device designed for general-purpose power applications that require high-voltage capability and long life at elevated temperatures.

This part delivers a 2000-hour endurance at 105°C under rated ripple conditions, features improved safety for abnormal voltage events, and is supplied in tray packing for mass production assembly.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage, suitable for high-voltage filtering and energy buffering in power circuits.
• High-temperature Endurance — Rated for 2000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance change remains within ±20% after endurance test.
• Snap-in Radial Can Package — Snap-in terminal, radial can construction for secure board mounting and simplified assembly in power subassemblies.
• Operating Temperature Range — Specified to operate from −25°C to +105°C, supporting equipment that experiences elevated ambient temperatures.
• Ripple Current Performance — 700 mA at 120 Hz (low frequency) and 805 mA at 10 kHz (high frequency), enabling effective smoothing under varying ripple conditions.
• Safety Features — Designed with improved safety for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions without dangerous outcomes.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20%; polarized device for DC applications.
• Compliance & Packaging — RoHS compliant and delivered in tray packing suitable for mass production workflows.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling in high-voltage DC supplies where 400 V rating and high ripple endurance are required.
• Industrial Power Electronics — Energy buffering and filtering in converters and inverters used in industrial equipment operating in voltage-fluctuating environments.
• DC Link and Energy Storage — Local energy storage and transient suppression in high-voltage DC link circuits.

Unique Advantages

• High-voltage capability: 400 V rating provides headroom for high-voltage power designs without upsizing capacitance value.
• Proven high-temperature life: 2000-hour endurance at 105°C under rated ripple current assures predictable performance in hot operating environments.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 10 kHz support performance across low- and high-frequency power stages.
• Safety-oriented design: Improved abnormal-voltage protection and a pressure relief vent reduce risk in over-voltage events.
• Production-ready packaging: Tray packing and snap-in terminals simplify integration into automated assembly and bulk production workflows.
