LGN2H151MELC25

The LGN2H151MELC25 is a snap-in terminal, large-can aluminum electrolytic capacitor from Nichicon’s LGN series, offered for general-purpose power applications. It delivers 150 µF capacitance at a 500 V rating with a compact φ35 × 25 mm case and is designed for long-duration operation up to 105°C.

Key value comes from its high-voltage capability, engineered endurance under rated ripple conditions (3000 hours at 105°C), and robust ripple-current performance across low and high frequencies—making it suitable where sustained high-voltage filtering and energy smoothing are required.

Key Features

• Electrical Performance — 150 µF capacitance at a 500 V rating with tolerance ±20% (–20% to +20%), and tanδ specified at 0.20 (measured at 20°C, 120 Hz).
• Ripple Current Capability — Handles 750 mA at 120 Hz (low frequency) and 1.073 A at 100 kHz (high frequency), supporting continuous ripple loading in demanding circuits.
• Leakage and Stability — Specified leakage current of 820 µA, with endurance characteristics that maintain capacitance, tanδ and leakage within datasheet limits after 3000 hours at 105°C under rated ripple.
• Thermal and Lifetime Rating — Rated for operation from –25°C to +105°C with a 3000-hour endurance rating at 105°C when subjected to DC bias plus rated ripple current.
• Package and Mounting — Snap-in radial can (φ35 × 25 mm), snap-in terminal type for secure board mounting and tray packing for handling in production environments.
• Compliance — RoHS compliant per provided product data.

Typical Applications

• General-Purpose Power Systems — Provides high-voltage bulk capacitance for filtering and energy storage where a 500 V rating and 150 µF value are required.
• Power Conversion and DC Link — Useful in circuits that demand sustained ripple handling, leveraging 750 mA (120 Hz) and 1.073 A (100 kHz) ripple current capability.
• Industrial Electronics — Supports long-duration, high-temperature operation (3000 h at 105°C) for industrial power assemblies and equipment.

Unique Advantages

• High-Voltage Capability: 500 V rated voltage enables use in high-voltage sections of power supplies and converters without stacking smaller capacitors.
• Long Endurance at Elevated Temperature: Specified 3000-hour endurance at 105°C under rated ripple current, providing predictable aging and maintenance scheduling.
• Dual-Frequency Ripple Handling: Rated ripple currents for both low (120 Hz) and high (100 kHz) frequencies accommodate a range of switching and line-frequency stress profiles.
• Compact Snap-In Package: φ35 × 25 mm can with snap-in termination offers a space-efficient, secure mounting option for through-hole assembly.
• Clear Performance Limits: Specified tanδ, leakage current, and tolerance figures allow straightforward design margining and validation against system requirements.
• RoHS Compliance: Conforms to RoHS directives as stated in the product data, supporting environmentally constrained designs.
