LGZ2W101MELB30

The LGZ2W101MELB30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGZ long‑life series. It delivers 100 µF capacitance at a 450 V rating with polarized, radial can construction designed for general‑purpose power applications that require sustained performance at elevated temperatures.

Engineered for long life, this part is specified for continuous operation up to 105°C with a 20,000‑hour endurance at that temperature, offering predictable aging and stable electrical characteristics over extended service intervals.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable where high DC voltage energy storage is required.
• Package & Mounting: Radial can, snap‑in terminal type for robust board retention and straightforward assembly into power modules and chassis‑mount designs. Size φD × L = 30 × 30 mm.
• High‑Temperature Long Life: Designed for operation from −25°C to +105°C with a rated endurance of 20,000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance: Rated ripple current 640 mArms at 105°C, 120 Hz; frequency performance yields higher allowable ripple at elevated frequencies (example: 915.2 mA at 50 kHz as specified).
• Electrical Reliability: Leakage current specified by I ≤ 3√CV (μA) after 5 minutes at 20°C and tan δ ≤ 0.20 (120 Hz at 20°C), supporting predictable filtering and smoothing behavior.
• Regulatory Compliance: Compliant with RoHS (2011/65/EU,(EU)2015/863), meeting current lead‑restriction environmental requirements.

Typical Applications

• Power supply filtering: Bulk smoothing and DC link decoupling in high‑voltage power supplies where 450 V capability and long life at elevated temperature are required.
• High‑voltage energy storage: Local energy reservoir for circuits that need 100 µF at 450 V to stabilize voltage rails during load transients.
• Industrial power systems: Use in industrial converters and power modules for reliable long‑term operation under continuous thermal stress up to 105°C.

Unique Advantages

• Long‑life assurance: 20,000 hours endurance at 105°C provides predictable lifespan and reduces the frequency of capacitor replacement in service.
• High voltage rating: 450 V rating enables use in elevated DC bus and high‑voltage circuits without overspecifying capacitance.
• Robust ripple capability: 640 mArms rated ripple at 120 Hz and higher allowable ripple at increased frequencies support demanding filtering duties.
• Secure snap‑in mounting: Snap‑in terminals offer stable mechanical retention for heavy copper or chassis assemblies, simplifying board layout and assembly.
• Measured electrical stability: Tight specifications for leakage current and tan δ allow predictable behavior after long‑term operation and shelf storage per the datasheet endurance and shelf‑life criteria.
• RoHS compliant: Meets current environmental restriction requirements for lead‑free assemblies.
