LAKW6151MELA40ZB

The LAKW6151MELA40ZB is a snap‑in terminal type aluminum electrolytic capacitor from Nichicon’s LAK series, designed for high‑voltage power applications. With a rated voltage of 420 V and 150 µF capacitance, this polarized, radial can capacitor provides high‑temperature endurance and stable performance for industrial and power‑electronics designs.

Its combination of 105°C permissible operating temperature, 2000 hours endurance at 105°C, and safety‑focused construction make it suitable for equipment operating in voltage‑fluctuating environments where long service life and reliable ripple handling are required.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance, suited for bulk filtering and energy storage in high‑voltage circuits.
• Snap‑In Radial Can — Snap‑in terminal, radial can package for secure PCB mounting and simplified assembly in power supply and converter modules.
• High‑Temperature Endurance — Specified lifetime of 2000 hours at 105°C; designed to meet endurance requirements after extended high‑temperature ripple exposure.
• Ripple Current Capability — 820 mA at 120 Hz (low frequency) and 943 mA at 10 kHz (high frequency) to support smoothing and decoupling under real operating ripple conditions.
• Low Dissipation Factor — tan δ ≤ 0.20 at 20°C and 120 Hz for controlled losses and predictable thermal behavior in power circuits.
• Leakage Current — Specified leakage current of 750 µA, enabling predictable standby loss and charge retention behavior.
• Operating Temperature Range — Rated for −25°C to +105°C to cover a broad range of industrial and commercial environments.
• Safety and Robustness — LAK series features improved safety measures for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous outcomes under test conditions.
• Packaging & Production — Tray packing and mass production availability for volume manufacturing and reliable supply chain integration.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy storage at high DC bus voltages in switch‑mode and linear power supplies.
• Inverters & Motor Drives — DC link smoothing and ripple absorption where high voltage and elevated temperature endurance are required.
• Uninterruptible Power Systems (UPS) — Energy buffering and decoupling on high‑voltage rails for reliable backup power operation.
• Power Conversion Modules — Support for high‑voltage converters and power conditioners that demand robust ripple handling and long life at elevated temperatures.

Unique Advantages

• High‑Voltage Rating: 420 V capability provides headroom for high‑voltage DC bus designs and systems with voltage fluctuation.
• Designed for High‑Temperature Duty: 2000 hours endurance at 105°C maintains capacitance, tan δ and leakage within specified limits after extended stress.
• Frequency‑Versatile Ripple Performance: Specified ripple currents at both 120 Hz and 10 kHz support realistic low‑ and high‑frequency filtering needs.
• Predictable Electrical Losses: Low tan δ (0.20 max at 20°C/120 Hz) helps manage dissipation and thermal rise in dense power assemblies.
• Safety‑Oriented Construction: Improved safety measures and a pressure relief vent reduce risk under abnormal overvoltage conditions.
• Mechanical Fit for PCB Assembly: Snap‑in radial can (φ25 × 40 mm / L: 4.0 cm × D: 2.5 cm) simplifies mounting in modular power boards and systems.
