LGW2W151MELB25

The LGW2W151MELB25 is a snap‑in terminal aluminum electrolytic capacitor rated at 450 V with 150 µF capacitance. It is designed for general-purpose applications that require high ripple capability and robust high‑voltage performance.

Key value propositions include high ripple current handling and demonstrated endurance under rated ripple conditions at elevated temperature — withstanding 3000 hours of rated ripple current at 105 °C — while meeting RoHS requirements.

Key Features

• High Voltage Rating — Rated voltage of 450 V for high‑voltage circuits.
• Capacitance — 150 µF nominal capacitance with a tolerance of ±20% (–20%~20%).
• High Ripple Current — Specified ripple current: 1.31 A at 120 Hz and 1.873 A at 50 kHz, supporting demanding ripple conditions.
• Endurance at Elevated Temperature — Withstands 3000 hours of rated ripple current at 105 °C when tested per series endurance conditions.
• Package and Mounting — Snap‑in radial can (φ30×25L) for secure PCB mounting; package dimensions: L: 2.5 cm × D: 3 cm.
• Operating Temperature — Rated for operation from –25 °C to +105 °C (450‑V category).
• Polarized — Polarized electrolytic design for DC applications.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose High‑Voltage Designs — Suitable for general-purpose circuits that require a 450 V, 150 µF snap‑in electrolytic capacitor.
• High‑Ripple Environments — Targeted for applications where sustained ripple current at elevated temperature is expected, supported by 3000 hour endurance at 105 °C.
• PCB Snap‑in Mounting — Designed for assemblies using snap‑in radial cans with φ30×25L footprint for secure board installation.

Unique Advantages

• Long Endurance Under Load: Rated to withstand 3000 hours of rated ripple current at 105 °C, providing predictable long‑term performance in demanding conditions.
• High Ripple Capability: Explicit ripple current ratings at both 120 Hz (1.31 A) and 50 kHz (1.873 A) enable designers to select the part with known AC stress limits.
• High Voltage Capacity: 450 V rating supports high‑voltage system requirements without sacrificing capacitance.
• Compact Snap‑in Form Factor: φ30×25L radial can with snap‑in terminals simplifies secure PCB mounting for power modules and assemblies.
• Wide Operating Temperature: –25 °C to +105 °C operational range for 450‑V applications ensures stability across common industrial temperature conditions.
• Regulatory Compliance: RoHS conformity supports use in designs targeting regulatory compliance in applicable regions.
