LAK2D471MELB25

The LAK2D471MELB25 is a Nichicon LAK series aluminum electrolytic capacitor in a snap-in terminal can, rated for 200V and 470µF nominal capacitance. It is designed for general-purpose power applications that require high-voltage capability, measured ripple handling and long-term endurance at elevated temperatures.

With a permitted operating range from −25°C to 105°C, 2000 hours of rated-life endurance at 105°C, and built-in safety measures for abnormally excessive voltage, this component targets industrial and power-electronics designs where robust filtering and reliable operation under ripple and fluctuating voltage conditions are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a 200 V rated voltage with ±20% tolerance, suitable for medium-voltage energy storage and smoothing.
• Ripple Current Performance — Rated ripple current of 1.35 A at 120 Hz and 1.62 A at 10 kHz, supporting both low- and high-frequency ripple loads.
• Endurance at Elevated Temperature — 2000 hours life specification at 105°C under DC bias plus rated ripple current, with defined limits on capacitance change, tan δ and leakage after test.
• Safety & Abnormal Voltage Handling — LAK series improvements for safety under abnormally excessive voltage and a pressure relief vent designed to operate without flames or dispersion of fragments.
• Loss Angle & Leakage — tan δ specified at 0.20 max (120 Hz, 20°C) and measured leakage current specified (product nominal leakage: 910 µA), enabling predictable loss and standby characteristics.
• Package & Mounting — Radial, snap-in can package (φ30 × 25L mm) designed for secure panel or chassis mounting; supplied in tray packing and listed as mass production status for supply continuity.
• Environment — RoHS compliant, supporting regulatory requirements for lead-free systems.

Typical Applications

• General-purpose power supplies — smoothing and bulk energy storage where a 200 V, 470 µF capacitor with defined ripple ratings is required.
• Industrial equipment in fluctuating-voltage environments — designed for applications described as suited to equipment operating under variable or fluctuating supply voltages.
• Power conversion circuits — bulk filtering and ripple handling in circuits that impose both low- and high-frequency ripple currents.

Unique Advantages

• High-voltage capability: 200 V rating allows use in higher-voltage power stages where lower-voltage capacitors cannot be applied.
• Measured ripple handling: Specified ripple current at 120 Hz and 10 kHz provides clear limits for thermal and lifetime planning under real-world ripple loads.
• Long-term thermal endurance: 2000 hours at 105°C under rated conditions supports designs requiring sustained high-temperature reliability.
• Enhanced safety features: Series-level protections for abnormal voltage and a pressure relief vent reduce the risk of dangerous failure modes under over-voltage stress.
• Compact snap-in form factor: φ30 × 25L can with snap-in terminals simplifies secure mounting in high-density power assemblies and supports tray-based production handling.
• Regulatory compliance: RoHS conformity supports use in lead-free product lines and regulatory-aligned manufacturing.
