LAK2G470MELA20

The LAK2G470MELA20 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 47 µF at 400 V in a radial, snap‑in can package sized Ø25 × 20 mm, offering high‑voltage capability and robust thermal endurance.

Engineered for equipment operating in fluctuating voltage environments, this part combines a 105 °C rated operating temperature, a 2000‑hour endurance at 105 °C under rated ripple, and built‑in safety features for abnormal overvoltage conditions.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance at 400 V for high‑voltage smoothing, decoupling, and energy storage in power circuits.
• Snap‑In Package — Radial, can snap‑in mounting simplifies PCB retention and mechanical stability for high‑current or vibration‑prone assemblies.
• High Temperature Endurance — Rated for −25 °C to +105 °C with 2000 hours endurance at 105 °C when subjected to D.C. bias plus rated ripple current.
• Ripple Performance — Handles 350 mA (120 Hz) and 402.5 mA (10 kHz) ripple current, supporting both low‑ and high‑frequency power applications.
• Leakage & Loss — Specified leakage current of 410 µA and tan δ ≤ 0.20 (120 Hz, 20 °C), enabling predictable loss and leakage behavior for design margining.
• Safety Design — Includes improved safety features for abnormally excessive voltage and a pressure relief vent that operates without dangerous flame or fragmentation.
• Compliance & Packaging — RoHS compliant; supplied in tray packing for mass production handling.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy buffering where 400 V ratings and sustained ripple endurance at 105 °C are required.
• Voltage‑Fluctuation Environments — Circuits exposed to varying input voltages benefit from the LAK series’ improved safety features for abnormal voltages.
• Commercial Inverters and Converters — Smoothing and ripple suppression in mid‑to‑high voltage DC link and power conversion stages.

Unique Advantages

• High‑Voltage, Compact Footprint: 47 µF at 400 V in a Ø25 × 20 mm can saves board space while meeting high‑voltage requirements.
• Proven Thermal Endurance: 2000‑hour performance at 105 °C under rated ripple current provides predictable aging behavior for thermal‑stress designs.
• Dual‑Frequency Ripple Capability: Rated ripple current at both 120 Hz and 10 kHz supports a wide range of power topologies and switching frequencies.
• Safety‑Focused Construction: Pressure relief vent and abnormal‑voltage protections reduce risk under overvoltage events, aiding safer system behavior.
• Production‑Ready Packaging: Tray packing and mass production availability simplify procurement and assembly for volume manufacturing.
• Regulatory Compatibility: RoHS compliance supports use in regions requiring lead‑restricted components.
