LGN2W151MELY45

The LGN2W151MELY45 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic equipment that requires a compact, high-voltage capacitor. It combines a 150 µF capacitance with a 450 V rating in a smaller-sized snap-in can that supports sustained operation at elevated temperature.

Key value comes from its 105°C endurance (designed to withstand 3000 hours of rated ripple current at 105°C), compact radial snap-in package, and RoHS compliance for regulated environments.

Key Features

• Electrical Performance — 150 µF capacitance at a 450 V rated voltage with ±20% tolerance; polarized for DC applications.
• High-Temperature Endurance — Rated for operation up to 105°C with endurance validated for 3000 hours under rated ripple current at 105°C.
• Ripple Current Capability — Rated ripple current of 790 mA at 120 Hz and 1.13 A at 100 kHz, supporting both low- and high-frequency ripple conditions.
• Package & Mounting — Radial, snap-in can for secure chassis mounting; physically compact one rank smaller than LGU series with size L: 4.5 × D: 2 cm.
• Reliability Metrics — Leakage current defined as I ≤ 3/√C (µA) after 5 minutes at 20°C; tan δ maximum of 0.20 for the 450 V rating.
• Temperature Stability — Category temperature range applicable at this voltage: –25°C to +105°C; impedance stability defined in the datasheet for low-temperature performance.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Provides high-voltage bulk capacitance where a 150 µF, 450 V polarized capacitor is required in a compact snap-in form.
• High-temperature environments — Suited for assemblies that require reliable operation up to 105°C with documented 3000-hour endurance at rated ripple current.
• Compact high-voltage designs — Useful where one-rank-smaller case size than LGU helps reduce enclosure space while maintaining high-voltage capability.

Unique Advantages

• Verified high-temperature endurance: Endurance testing at 105°C for 3000 hours under rated ripple current provides a measurable reliability baseline.
• Compact snap-in package: One-rank-smaller case than the LGU series reduces board or chassis footprint while keeping snap-in mounting robustness.
• Clear electrical specifications: Defined ripple current values at both 120 Hz (790 mA) and 100 kHz (1.13 A) help predict thermal and ripple handling in design.
• Quantified leakage and loss characteristics: Leakage current limit (I ≤ 3/√C µA) and tan δ max of 0.20 at 450 V support predictable performance and margining.
• Regulatory readiness: RoHS compliance supports deployment in regions and programs that require restricted substances conformance.
