Overview of LGUW6181MELA – 420 V, 180 µF Snap‑In Aluminum Electrolytic Capacitor

The LGUW6181MELA is a snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage, high‑temperature applications. It delivers 180 µF at a rated voltage of 420 V in a radial, can-style snap‑in package with RoHS compliance and tray packing for production use.

Built for sustained performance at elevated temperatures, this capacitor offers a 3000‑hour endurance at 105°C with rated ripple current capability, making it suitable for general‑purpose power applications that require durable, high‑voltage bulk capacitance.

Key Features

  • High Voltage Rating — Rated voltage 420 V suitable for high‑voltage power circuits requiring reliable bulk capacitance.
  • Capacitance and Tolerance — 180 µF with ±20% tolerance specified at 120 Hz and 20°C for predictable charge storage.
  • High Temperature Endurance — Qualified for 3000 hours at 105°C under DC bias plus rated ripple current; capacitance change remains within ±20% after endurance test.
  • Low Loss (tan δ) — tan δ = 0.15 maximum (measured at 120 Hz, 20°C for 160–420 V range), supporting stable performance under load.
  • Ripple Current Capability — Rated ripple current 950 mA at 120 Hz (low frequency) and 1.359 A at 50 kHz (high frequency) to handle AC ripple in power supplies.
  • Controlled Leakage — Specified leakage current (820 µA) for predictable standby currents and startup behavior.
  • Rugged Package & Mounting — Snap‑in radial can (φ25 × 35L / L: 3.5 × D: 2.5 cm) for robust PCB mounting and ease of assembly in production.
  • Compliance & Production Readiness — RoHS compliant and listed as mass production status with tray packing for volume manufacturing.

Typical Applications

  • General Purpose Power Electronics — Provides high‑voltage bulk capacitance in designs that require 420 V rating and sustained operation at up to 105°C.
  • Power Supply Filtering — Supports smoothing and ripple handling where rated ripple current and low loss (tan δ) are required.
  • High‑Temperature Environments — Suitable where long endurance at elevated temperatures is needed, backed by a 3000‑hour life specification at 105°C.

Unique Advantages

  • Rated for Sustained High‑Temperature Duty — 3000 hours at 105°C ensures long‑term stability under continuous high‑temperature conditions.
  • Designed for High‑Voltage Systems — 420 V rating enables use in higher voltage rails without sacrificing capacitance density.
  • Reliable Ripple Handling — Specified low‑ and high‑frequency ripple currents (950 mA at 120 Hz; 1.359 A at 50 kHz) reduce thermal stress and support robust power conditioning.
  • Predictable Electrical Behavior — Tight specification for tan δ (0.15 at 120 Hz, 20°C) and controlled leakage current (820 µA) assist in accurate circuit design and power budgeting.
  • Production‑Friendly Packaging — Snap‑in radial can and tray packing streamline assembly for mass production environments.
  • RoHS Compliance — Meets environmental regulatory requirements for electronics manufacturing.
