LGN2H101MELZ40

The LGN2H101MELZ40 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose applications that require high-voltage capability and elevated temperature endurance. It is a polarized, smaller-sized member of the LGN series engineered to deliver stable performance up to 105°C with long endurance under rated ripple current.

This part combines a 500 V rated voltage with 100 µF capacitance, snap-in mounting, and RoHS compliance, making it suited for equipment designs where reliable high-voltage bulk capacitance and compact snap-in packaging are needed.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance at a rated voltage of 500 V, suitable for high-voltage bulk capacitance requirements.
• High-Temperature Endurance: Rated for operation to 105°C and specified to withstand 3000 hours of rated ripple current at 105°C (endurance stated in series datasheet).
• Snap-In Terminal Package: Radial can with snap-in terminals for secure chassis or PCB mounting and straightforward mechanical installation.
• Compact Case Size: One rank smaller case size than the LGU series, with dimensions L: 4 × D: 2.2 cm and a maximum seated height of 1.575 inch, supporting space-conscious designs.
• Ripple Performance: Specified ripple current capability of 650 mA at 120 Hz and 929.5 mA at 100 kHz, enabling continuous AC ripple handling at rated conditions.
• Operating Range & Tolerance: Polarized capacitor with an operating temperature range of –25°C to +105°C and capacitance tolerance of –20% to +20%.
• RoHS Compliant: Complies with the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• General-purpose power circuits: Provides high-voltage bulk capacitance for smoothing and energy storage in equipment designs that require a 500 V rated capacitor.
• Industrial and commercial equipment: Suitable where elevated operating temperature (up to 105°C) and extended ripple-current endurance are required.
• Chassis-mounted or PCB snap-in installations: Snap-in terminal format simplifies mechanical mounting in assemblies that need secure, serviceable high-voltage capacitors.

Unique Advantages

• High-voltage capability: 500 V rating enables use in circuits that demand higher DC bus voltages without series stacking.
• Long ripple endurance at high temperature: Specified 3000-hour endurance at 105°C under rated ripple current supports reliable long-term operation in thermally demanding environments.
• Compact, space-saving footprint: One rank smaller case size than comparable LGU parts helps reduce enclosure space while maintaining required capacitance.
• Clear electrical performance data: Rated ripple currents at both 120 Hz and 100 kHz allow designers to assess suitability for their specific ripple conditions.
• Regulatory compliance: RoHS compliance simplifies integration into designs targeting restricted-substance regulations.
