LGL2W181MELZ35

The LGL2W181MELZ35 is an aluminum electrolytic capacitor in a snap-in radial can optimized for compact, high-voltage applications. It delivers 180 µF of capacitance at a 450 V rating and is specified for operating temperatures from –25°C to +105°C.

Designed for general-purpose use, this snap-in capacitor combines a high voltage rating, elevated temperature endurance and a small footprint to address designs that require reliable high-voltage capacitance with robust thermal performance.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 450 V rated voltage; capacitance tolerance ±20%.
• High‑temperature endurance — Rated for –25°C to +105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑in radial can package — Snap-in terminal mounting for secure PCB installation and mechanical stability in vertical assemblies.
• Compact dimensions — Physical size L: 3.5 × D: 2.2 cm and a seated height maximum of 1.378 inch, enabling space-efficient board layouts.
• Ripple current capability — Specified ripple current of 770 mA at 120 Hz and 1.101 A at 50 kHz; frequency coefficient for rated ripple current reaches 1.43 at 50 kHz for higher-frequency applications.
• Leakage and dissipation characteristics — Leakage current limited by I ≤ 3√(C·V) μA after 5 minutes at 20°C; tan δ specified up to 0.20 at 450 V (measurement at 120 Hz, 20°C).

Typical Applications

• General‑purpose high‑voltage circuits — Provides bulk capacitance where a 450 V rating and 180 µF are required.
• High‑temperature system environments — Suited for equipment that must withstand continuous operation up to 105°C with long endurance.
• Snap‑in mounting designs — Appropriate for assemblies that use snap-in radial can components for robust mechanical retention and simplified installation.

Unique Advantages

• High voltage capability: 450 V rating supports high-voltage circuit requirements without series stacking.
• Thermal endurance: 2000 hours at 105°C under rated stress provides predictable long-term behavior in hot operating conditions.
