LAK2G151MELA35

The LAK2G151MELA35 is a snap-in terminal aluminum electrolytic capacitor rated at 150 µF and 400 V, designed for general-purpose use in equipment exposed to fluctuating voltages. It combines high-temperature endurance and robust ripple handling in a radial, can-style snap-in package.

Key value propositions include a 105°C permissible operating temperature range with 2000 hours endurance at rated conditions, high ripple current capability across low and high frequencies, and built-in safety features for abnormal voltage events.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High-temperature Endurance — Specified for 2000 hours at 105°C under D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage current after the test.
• Ripple Current Performance — Supports 700 mA ripple current at 120 Hz and 805 mA at 10 kHz, enabling effective smoothing under varying frequency conditions.
• Low Loss — Tangent of loss angle (tan δ) of 0.20 max at 20°C, 120 Hz to help minimize dissipation during operation.
• Leakage Current — Low leakage current specified at 730 µA after rated voltage application, supporting reliable DC performance.
• Safety and Voltage Robustness — Designed with improved safety features and a pressure relief vent that operates under abnormal voltage conditions to reduce hazardous outcomes.
• Package & Mounting — Radial, can-style snap-in package (φ25 × 35 mm) for secure chassis or PCB mounting; tray-packed for production handling.
• Regulatory — RoHS compliant.

Typical Applications

• General-Purpose Electronic Equipment — Fits a wide range of equipment where a robust 400 V capacitor is required for energy storage and smoothing.
• Equipment Subject to Voltage Fluctuations — Specifically suited for systems operating in areas with fluctuating voltages thanks to extended voltage range options and enhanced safety design.
• Power Filtering and Smoothing — Effective for bulk filtering and ripple reduction in power conversion stages where the specified ripple current ratings are required.

Unique Advantages

• Long High‑Temperature Life: 2000 hours endurance at 105°C under rated ripple current preserves capacitance and performance in demanding thermal environments.
• Broad Ripple Handling: Dual ripple specifications (700 mA at 120 Hz and 805 mA at 10 kHz) cover low- and high-frequency smoothing needs without exceeding device limits.
• Safety-Focused Design: Pressure relief vent and improved abnormal-voltage protection reduce the risk of dangerous failures during overvoltage events.
• Low Dissipation: tan δ of 0.20 max at 20°C, 120 Hz helps limit internal heating and energy loss during operation.
• Production-Ready Packaging: Tray packing supports automated assembly and high-volume production workflows.
• Regulatory Compliance: RoHS-compliant construction supports environmental requirements for modern electronics manufacturing.
