Overview of LAK2G181MELB30ZB – 400 V, 180 µF Snap‑In Aluminum Electrolytic Capacitor

The LAK2G181MELB30ZB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAK series, delivering 180 µF at a 400 V rating in a compact radial can package. Designed for general‑purpose electronic equipment, it combines high ripple handling, extended operating temperature range, and enhanced safety measures for designs that encounter voltage fluctuations.

Key Features

  • Electrical Performance — 180 µF capacitance at a 400 V rated voltage with ±20% tolerance (120 Hz, 20°C) and a maximum tan δ of 0.20 (120 Hz, 20°C) for predictable AC loss characteristics.
  • Ripple Current Capability — Handles 800 mA at 120 Hz and 920 mA at 10 kHz, supporting applications with significant low‑ and high‑frequency ripple demands.
  • Leakage and Endurance — Specified leakage current of 800 µA and endurance of 2000 hours at 105°C, providing long‑term stability under elevated temperature and stress.
  • Package & Mounting — Radial, snap‑in can package with a compact footprint (≈30 mm × 30 mm) for secure mounting and efficient board placement in assemblies.
  • Safety & Voltage Robustness — Part of the LAK series enhancements for improved safety under abnormal overvoltage conditions; includes pressure relief venting designed to avoid dangerous failures.
  • Environmental Compliance & Production — RoHS‑compliant, supplied in tray packing and intended for mass production deployment.

Typical Applications

  • General‑purpose electronic equipment — Provides bulk capacitance and ripple handling where a 400 V, 180 µF capacitor profile is required.
  • High‑temperature systems — Suited to applications that operate up to 105°C and require components with proven endurance at that temperature.
  • Voltage‑fluctuating environments — Designed for equipment used in areas with fluctuating supply voltages, leveraging the LAK series' improved safety features.

Unique Advantages

  • High‑voltage capability: 400 V rating enables designs that need extended voltage headroom without up‑rating multiple components.
  • Robust ripple handling: Rated for 800 mA (120 Hz) and 920 mA (10 kHz) ripple current to support demanding AC and switching scenarios.
  • Long‑term high‑temperature endurance: 2000 hours at 105°C gives predictable lifetime performance in elevated‑temperature applications.
  • Safety‑focused design: LAK series enhancements and pressure relief venting reduce the risk of hazardous failure under abnormal voltage conditions.
  • Production ready: Tray packing and mass production availability simplify procurement and assembly scaling.
  • Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for electronic assemblies.
