LGX2D122MELA50

The LGX2D122MELA50 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGX series. It is a smaller-sized, polarized can-type capacitor designed for power-electronics environments requiring sustained ripple handling and long life at elevated temperatures.

Engineered for rectifier circuits used in general inverters and switching power supplies, this capacitor delivers rated performance at up to 105°C and is RoHS compliant.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance at a 200 V rated voltage with a tolerance of ±20% for general-purpose power applications.
• High-temperature long life — Rated to operate from −25°C to +105°C with a long-life assurance of 5000 hours when subjected to rated ripple current at 105°C.
• Ripple current capability — Handles 2.4 A at 120 Hz and 3.6 A at 50 kHz, supporting continuous ripple loading in power-conversion circuits.
• Package and mounting — Snap-in, radial can package suited for PCB insertion and secure mounting in power assemblies; smaller-sized footprint with dimensions L: 5 × D: 2.5 cm.
• Polarized construction — Designed for DC applications where polarity is maintained.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General inverters — Used in rectifier circuits within inverter power stages to support DC bus smoothing and ripple endurance at elevated temperatures.
• Switching power supplies — Applied on input or output stages where sustained ripple current and long life at 105°C are required.
• Power rectifier circuits — Suited for rectifier-filter roles in a variety of industrial and commercial power conversion systems.

Unique Advantages

• Designed for extended high-temperature operation — 5000-hour endurance at 105°C supports reliability in demanding thermal environments.
• Measurable ripple performance — Rated ripple currents (2.4 A at 120 Hz; 3.6 A at 50 kHz) allow engineers to specify the capacitor against known dynamic loading.
• Compact snap-in can — Smaller-sized radial can with snap-in terminals simplifies assembly while saving board space in power assemblies.
• Clear electrical specifications — 1.2 mF at 200 V with ±20% tolerance provides predictable capacitance for design calculations.
• Regulatory compliance — RoHS conformity supports deployment in markets requiring restricted-substance compliance.
