Overview of LAK2G181MELA40 – Aluminum Electrolytic Capacitor (Snap‑in), 400 V, 180 µF

The LAK2G181MELA40 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAK series, rated 400 V with a capacitance of 180 µF. It delivers polarized, high‑voltage energy storage in a compact radial can (φ25 × 40 mm) and is offered in tray packing for production use.

Designed for general‑purpose applications and equipment operating in voltage‑fluctuating environments, this part combines a 105°C permissible temperature rating with extended endurance and safety features defined by the LAK series specification.

Key Features

  • Electrical Ratings — 180 µF capacitance at 400 V rated voltage with ±20% tolerance (120 Hz, 20°C).
  • High‑temperature Endurance — Specified for 2000 hours of operation at 105°C under DC bias plus rated ripple current (LAK series endurance requirement).
  • Ripple Handling — Rated ripple current of 800 mA at 120 Hz and 920 mA at 10 kHz, suitable for applications requiring sustained ripple performance.
  • Safety Features — LAK series design includes improved safety measures for abnormally excessive voltage and a pressure relief vent that operates without creating hazardous conditions.
  • Package & Mounting — Radial, can‑type snap‑in terminal construction for secure board mounting; supplied in tray packing for manufacturing workflows.
  • Temperature Range & Reliability — Operating range −25°C to +105°C and RoHS‑compliant construction for regulatory compatibility.
  • Leakage & Polarization — Polarized electrolytic capacitor with specified leakage current (0.80 mA for this part).

Typical Applications

  • General‑purpose high‑voltage systems — Use where a 400 V, 180 µF polarized snap‑in capacitor is needed for energy storage and DC link duties.
  • Equipment in voltage‑fluctuating areas — LAK series safety features and extended voltage range make this part suitable for designs exposed to unstable supply conditions.
  • Production assemblies — Tray packing and snap‑in mounting support efficient installation in manufactured electronic assemblies.

Unique Advantages

  • Long endurance at elevated temperature — 2000 hours at 105°C provides predictable aging characteristics for sustained high‑temperature operation.
  • Clear performance specifications — Defined ripple currents at 120 Hz and 10 kHz and explicit leakage current values allow straightforward thermal and reliability calculations.
  • Safety‑oriented series design — Pressure relief vent and abnormally excessive voltage protections reduce risk in unstable voltage environments.
  • Manufacturing ready — Snap‑in terminal package and tray packing streamline assembly and handling for volume production.
  • Regulatory compliance — RoHS‑compliant construction supports environmentally constrained product requirements.
