Overview of LGX2W181MELB30 – 180 µF, 450 V Snap-in Aluminum Electrolytic Capacitor

The LGX2W181MELB30 is a snap-in terminal aluminum electrolytic capacitor designed for high-voltage power applications. It delivers 180 µF at 450 V with a long-life assurance rating of 5000 hours at 105°C, making it suitable for demanding rectifier and power conversion circuits.

Engineered for general-purpose power electronics, this smaller-sized LGX series part is optimized for rectifier circuits in inverters and switching power supplies where reliable high-voltage smoothing and ripple handling are required.

Key Features

  • High Voltage Capacity Rated at 450 V for applications requiring robust DC voltage tolerance.
  • Capacitance and Tolerance 180 µF nominal capacitance with a tolerance of ±20% (–20% to +20%) at 120 Hz, 20°C.
  • Long-Life Assurance Endurance verified for 5000 hours at 105°C under rated ripple current, supporting extended operation in high-temperature environments.
  • Ripple Current Performance Rated ripple current of 1.03 A at 120 Hz and 1.473 A at 50 kHz, suitable for smoothing and filtering in power conversion circuits.
  • Temperature Range Operational temperature range from –25°C to +105°C for consistent performance across typical industrial conditions.
  • Snap-In Radial Can Package Snap-in terminal type with a compact can package (approximately 3 × 3 cm) for secure board mounting in power assemblies.
  • Polarized Aluminum Electrolytic Polarized construction appropriate for DC smoothing and rectifier applications.
  • RoHS Compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • General Inverters Used in rectifier stages and DC link filtering where high-voltage smoothing and thermal endurance are required.
  • Switching Power Supplies Provides bulk capacitance and ripple handling in high-voltage switching regulators and power conversion modules.
  • Rectifier Circuits Suitable for general-purpose rectification and smoothing in industrial and power-electronics designs.

Unique Advantages

  • Extended High‑Temperature Reliability: 5000-hour endurance at 105°C under rated ripple current reduces maintenance and replacement frequency in thermally stressed systems.
  • High Voltage Handling: 450 V rating enables use in higher-voltage DC link and rectifier applications without series stacking.
  • Compact Snap‑In Packaging: Smaller-sized radial can with snap-in terminals simplifies PCB retention and mechanical stability in power assemblies.
  • Measured Ripple Capability: Specified ripple current values at both low and high frequencies (1.03 A at 120 Hz, 1.473 A at 50 kHz) help designers size components for real-world ripple conditions.
  • Wide Operating Range: –25°C to +105°C operation supports performance across common industrial temperature profiles.
  • Regulatory Compliance: RoHS conformity supports deployment in regions and products requiring hazardous-substance restrictions.
