LGX2W101MELZ30

The LGX2W101MELZ30 is a Nichicon LGX series aluminum electrolytic capacitor in a snap-in terminal (radial can) package. It delivers 100 µF capacitance at a 450 V rated voltage with polarized construction and is designed for general-purpose power applications.

Engineered for high-temperature, long-life operation, this component withstands rated ripple current for 5000 hours at 105°C and is suited for rectifier circuits in general inverters and switching power supplies. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 450 V rated voltage; capacitance tolerance is ±20% at 120 Hz, 20°C.
• High-temperature Long Life — Endurance specified as 5000 hours at 105°C when D.C. bias plus rated ripple current is applied; designed to maintain performance under elevated operating temperature.
• Snap-In Radial Package — Snap-in terminal / radial can package for secure mounting in power assemblies and ease of PCB installation.
• Ripple Current Capability — Rated ripple current: 690 mA at 120 Hz (low frequency) and 986.7 mA at 50 kHz (high frequency), supporting demanding power-conditioning duties.
• Thermal & Environmental Range — Operating temperature range from −25°C to +105°C; RoHS compliant (2011/65/EU, (EU)2015/863).
• Electrical Reliability Parameters — Leakage current specification: I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ max 0.20 for 450–500 V measured at 120 Hz and 20°C.
• Low-temperature Impedance — Impedance ratio Z(−25°C)/Z(+20°C) up to 8 for 400–500 V ratings, helping maintain performance at lower ambient temperatures.

Typical Applications

• Switching Power Supplies — Used on DC bus and rectifier stages to provide bulk energy storage and smoothing under high ripple stress.
• General Inverter Rectifiers — Suited for rectifier circuits in inverter systems where high voltage and sustained ripple endurance at elevated temperature are required.
• Power Conditioning Modules — Fits compact power modules that require a high-voltage, long-life electrolytic solution in a snap-in package.

Unique Advantages

• Proven High-temperature Endurance: Rated to withstand rated ripple current for 5000 hours at 105°C, providing predictable aging and lifecycle behavior in hot enclosures.
• High Voltage Handling: 450 V rating enables use in higher-voltage DC bus and rectifier applications without up-rating multiple devices in series.
• Robust Ripple Performance: Measured ripple current capability at both 120 Hz and 50 kHz supports use with a range of switching frequencies and rectifier conditions.
• Compact Snap-In Form Factor: Radial snap-in can simplifies board assembly and secures the capacitor in vertical power assemblies while saving PCB area.
• Measurable Reliability Limits: Endurance and shelf-life criteria (capacitance change, tan δ, leakage current) are defined and verifiable against datasheet conditions.
• Standards Compliance: RoHS compliant, supporting environmental requirements for commercial and industrial applications.
