Overview of LAK2G470MELB20 – 47 µF, 400 V Snap‑In Aluminum Electrolytic Capacitor

The LAK2G470MELB20 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAK series, rated 47 µF at 400 V. It is a polarized, radial can component designed for general‑purpose power applications and equipment that experiences voltage fluctuation.

Built for high‑temperature operation, the device delivers extended endurance and measured ripple performance for designs requiring reliable bulk capacitance in a compact snap‑in package.

Key Features

  • Capacitance & Voltage: 47 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (at 120 Hz, 20°C).
  • Package & Mounting: Snap‑in terminal, radial can (snap‑in) construction for secure chassis/board mounting; physical size approximately φ30 × 20 mm (D × L).
  • Temperature Range & Lifetime: Rated for −25°C to +105°C operation with a demonstrated endurance of 2000 hours at 105°C.
  • Ripple Current & Leakage: Rated ripple current of 400 mA at 120 Hz and 460 mA at 10 kHz, with a specified leakage current of 410 µA.
  • Dissipation Factor: tan δ ≤ 0.20 (120 Hz, 20°C), supporting stable AC performance.
  • Safety & Abnormal Voltage Tolerance: LAK series includes improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous conditions.
  • Environmental Compliance: RoHS‑compliant construction.

Typical Applications

  • General‑purpose power equipment — Suitable where a polarized, high‑voltage electrolytic capacitor is required for energy storage and smoothing in general designs.
  • Equipment subject to voltage fluctuation — LAK series features improved tolerance for abnormal voltages, making this part appropriate for systems operating in variable supply environments.
  • High‑temperature endurance applications — Use in assemblies that require continuous operation at elevated ambient temperatures up to 105°C with long rated life.

Unique Advantages

  • High‑voltage capability: 400 V rating enables use in higher DC voltage rails without series stacking.
  • Long high‑temperature endurance: 2000 hours at 105°C supports reliable life under elevated thermal stress.
  • Measured ripple performance: Specified ripple currents of 400 mA (120 Hz) and 460 mA (10 kHz) provide quantifiable AC handling for power circuits.
  • Secure snap‑in installation: Radial, snap‑in can design simplifies mounting and mechanical retention in chassis or board applications.
  • Built‑in safety features: Improved protection against abnormally excessive voltage and a designed pressure relief vent enhance operational safety.
  • Regulatory compliance: RoHS compliance supports use in environmentally restricted regions and products.
