LGZ2W151MELB40

The LGZ2W151MELB40 is a Nichicon LGZ series aluminum electrolytic capacitor in a snap-in radial can package. It delivers 150 µF capacitance at a 450 V rating with a ±20% tolerance and is specified for general-purpose use.

Designed for extended operation at elevated temperatures, this snap-in capacitor offers a 20,000 hour endurance at 105°C, high ripple handling, low leakage, and tray packaging for production-scale deployment.

Key Features

• Electrical Performance — 150 µF capacitance at 450 V rated voltage with ±20% tolerance, polarized design for DC power applications.
• Ripple Current & Frequency Response — Rated ripple current 790 mA at 120 Hz (105°C). Measured high-frequency ripple capability is 1.13 A at 50 kHz; frequency coefficient rises up to 1.43 at 50 kHz or more as listed in the series data.
• Long-Life Endurance — Specified endurance of 20,000 hours at 105°C with defined limits: capacitance change within ±25% of initial value, tan δ ≤ 250% of initial, and leakage current not exceeding initial specified value after endurance testing.
• Temperature Range — Operating temperature range from −25°C to +105°C, matching the LGZ series long-life assurance.
• Leakage & Dissipation — Typical leakage current 770 µA (after 5 minutes at rated voltage and 20°C); tan δ specified 0.20 max (120 Hz, 20°C) in the series data.
• Package & Mounting — Snap-in terminal, radial can package sized φ30 × 40 mm for secure board mounting; supplied in tray packing for mass-production handling.
• Environmental Compliance — RoHS-compliant per the product information.

Typical Applications

• General-purpose power electronics — Applied where a 450 V, 150 µF electrolytic capacitor with long thermal endurance is required for DC bus or high-voltage systems.
• Industrial equipment — Suited to equipment designs that demand extended life at elevated temperatures (20,000 h at 105°C) and reliable ripple handling.
• High-voltage assemblies in production — Tray-packed snap-in format supports production workflows for assemblies that need consistent high-voltage capacitance and manufacturing-ready packaging.

Unique Advantages

• Extended high-temperature life: 20,000 hour endurance at 105°C supports longer maintenance intervals and equipment longevity.
• High-voltage capability in a compact can: 450 V rating with 150 µF capacitance in a φ30 × 40 mm package provides dense energy storage for high-voltage circuits.
• Robust ripple handling: 790 mA rated ripple at 120 Hz and 1.13 A measured at 50 kHz improve performance under AC ripple and switching environments.
• Production-ready packaging: Tray packing and snap-in terminals simplify high-volume assembly and secure PCB installation.
• Predictable post-test performance: Endurance and shelf-life specifications define allowable capacitance, tan δ, and leakage limits after stress, aiding reliability planning.
• Regulatory compliance: RoHS status supports deployment in environments requiring restricted substance compliance.
