LAKW6470MELZ25

The LAKW6470MELZ25 is a Nichicon LAK series aluminum electrolytic capacitor with a snap‑in terminal style, rated 47 µF at 420 V. It is designed for general‑purpose power applications where high voltage capability, elevated‑temperature endurance and enhanced safety under abnormal voltages are required.

Key value comes from its 2000‑hour endurance at 105°C, snap‑in packaging for through‑hole assembly, and series safety features that address abnormally excessive voltage conditions—making it suitable for equipment operating in voltage‑fluctuating environments and for volume production.

Key Features

• Rated Capacitance and Voltage: 47 µF at 420 V, providing a compact high‑voltage solution for power circuits that require polarized aluminum electrolytic capacitance.
• High‑Temperature Endurance: Specified for 2000 hours at 105°C; capacitance, tan δ and leakage meet endurance limits after that test condition as defined by the series.
• Ripple Current Capability: Supports 350 mA at 120 Hz and 402.5 mA at 10 kHz, enabling effective handling of AC ripple in power conversion stages.
• Leakage and Loss Characteristics: Low leakage current of 0.42 mA and a maximum tan δ of 0.20 (120 Hz, 20°C) for controlled dissipation and predictable behavior in DC circuits.
• Enhanced Safety for Abnormal Voltage: LAK series design incorporates improved safety features and a pressure relief vent to mitigate hazardous conditions under abnormal voltage stress.
• Snap‑in Radial Can Package: φ22 × 25 mm (D × L) radial can with snap‑in terminals for secure mounting in through‑hole assemblies and compatibility with tray packing for mass production.
• Operating Range and Tolerance: Polarized device with an operating temperature range of −25°C to +105°C and capacitance tolerance of ±20%.
• RoHS Compliant: Manufactured in compliance with RoHS directives for regulatory environmental requirements.

Typical Applications

• General‑purpose power equipment: Suitable where a 47 µF, 420 V polarized capacitor with high ripple capability and elevated‑temperature endurance is required.
• Voltage‑fluctuating environments: Designed for equipment exposed to varying or abnormal voltages—series features improve safety under such conditions.
• Through‑hole, high‑volume assemblies: Snap‑in terminal and tray packing support efficient insertion and assembly for mass production runs.

Unique Advantages

• High‑voltage capability: 420 V rating lets designers use a single capacitor solution in higher‑voltage DC buses and circuits.
• Designed for elevated‑temperature durability: 2000 hours at 105°C endurance provides predictable performance for equipment operating in hot environments.
• Robust ripple handling: Specified ripple currents at 120 Hz and 10 kHz support reliable smoothing and filtering under AC ripple stress.
• Safety‑oriented construction: Improved series safety features and a pressure relief vent reduce risk during abnormal voltage events.
• Production‑friendly packaging: Snap‑in radial can and tray packing simplify PCB assembly workflows and help streamline high‑volume manufacturing.
• Regulatory compliance: RoHS compliance supports environmental and regulatory goals without additional qualifiers.
