Overview of LASW6181MELB30 – Snap-in Aluminum Electrolytic Capacitor, 180 µF / 420 V

The LASW6181MELB30 is a snap-in terminal aluminum electrolytic capacitor offering 180 µF capacitance at a 420 V rating. Designed for general-purpose high-voltage applications, it combines a compact snap-in can package with high ripple-current capability and extended endurance at elevated temperature.

This part is specifically suited for equipment operating in areas with fluctuating supply voltage, providing enhanced safety features against abnormally excessive voltage and proven performance after long-term ripple-stress at 105 °C.

Key Features

  • Electrolytic Snap-in Construction Robust radial, can-style snap-in package for secure panel or chassis mounting in high-voltage assemblies.
  • Rated Capacitance & Voltage 180 µF nominal capacitance with a 420 V DC rated voltage and ±20% tolerance.
  • High-Temperature Endurance Specified to withstand 2000 hours of rated ripple current at 105 °C, meeting endurance criteria after D.C. bias plus ripple stress.
  • Ripple Current Performance Rated for 900 mA at 120 Hz and 1.035 A at 10 kHz, with frequency coefficients provided for different operating frequencies.
  • Wide Operating Temperature Range Operates from −25 °C to +105 °C with low-temperature impedance stability (Z(−25 °C)/Z(+20 °C) ≤ 8).
  • Safety Design Improved safety features for abnormally excessive voltage, including a pressure relief vent that operates without flames, ignition, or dispersion of case pieces under test conditions.
  • RoHS Compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
  • Compact Footprint φ30 × 30 mm can size provides a smaller case profile while delivering higher ripple-current capability compared to the LAQ series.

Typical Applications

  • General-purpose high-voltage smoothing and filtering — Suited for DC link, bulk filtering, and smoothing in high-voltage circuits where 420 V ratings are required.
  • Equipment in fluctuating-voltage environments — Designed for devices and installations exposed to supply variations, benefiting from enhanced safety measures and ripple endurance.
  • Compact high-ripple assemblies — Ideal where smaller case size and elevated ripple-current capability are required in radial snap-in configurations.

Unique Advantages

  • Proven high-temperature endurance: Rated for 2000 hours at 105 °C under rated ripple current, ensuring sustained performance in hot operating conditions.
  • Elevated ripple-current capability: Explicit ripple ratings at 120 Hz and 10 kHz (900 mA and 1.035 A respectively) reduce thermal stress and improve lifetime in ripple-intensive applications.
  • Safety-focused design: Pressure relief vent and tested safety performance for abnormal over-voltage events reduce risk of flame or case dispersion.
  • Smaller case, higher performance: φ30 × 30 mm package delivers a smaller footprint while offering higher ripple capacity compared to the LAQ series.
  • Low-temperature stability: Impedance ratio limited to 8 at −25 °C vs +20 °C, supporting performance across the specified operating range.
  • Regulatory compliance: RoHS conformity supports deployment in markets requiring hazardous-substance restrictions.

Why Choose LASW6181MELB30?

The LASW6181MELB30 positions itself as a compact, high-voltage electrolytic solution for designs that demand robust ripple handling, extended high-temperature endurance, and enhanced safety under abnormal voltage conditions. Its snap-in can packaging and φ30 × 30 mm footprint make it suitable for space-constrained power assemblies that still require reliable bulk capacitance at 420 V.

Engineers specifying this capacitor benefit from clear, verifiable performance data—ripple current ratings, 2000-hour endurance at 105 °C, and low-temperature impedance limits—helping reduce design risk in applications exposed to supply fluctuations or continuous ripple stress.
