LGN2C122MELC25

The LGN2C122MELC25 is a polarized, snap-in terminal aluminum electrolytic capacitor from Nichicon's LGN series. It is a radial, can-style component designed for general-purpose use where robust ripple handling and high-temperature endurance are required.

Key attributes include a 1.2 mF capacitance at 160 V, rated operation from −40 °C to 105 °C, RoHS compliance, and the ability to withstand 3000 hours of rated ripple current at 105 °C.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance with a rated voltage of 160 V and a tolerance of −20% to +20%.
• High-temperature Endurance — Specified to withstand 3000 hours of application of rated ripple current at 105 °C, meeting the LGN series endurance criteria.
• Ripple Current Performance — Rated ripple current of 2.3 A at 120 Hz and 3.45 A at 100 kHz, supporting demanding AC ripple conditions within the specified limits.
• Package & Mounting — Snap-in, radial can package for secure board anchoring and replacement-friendly installation; one rank smaller case size than the LGU series.
• Operating Range — Wide operating temperature range from −40 °C to 105 °C for use in elevated-temperature environments covered by the LGN specification.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Compact radial can with dimensions L: 2.5 × D: 3.5 cm and a seated height up to 2.5 cm, facilitating layout in space-constrained designs.

Typical Applications

• Power supply filtering — General-purpose smoothing and bulk energy storage on power supply rails where high ripple handling and elevated-temperature endurance are needed.
• DC decoupling — Local decoupling for boards and modules to reduce voltage ripple using the specified ripple current capabilities.
• PCB power modules — Snap-in radial can form factor for secure mounting in discrete power assemblies and replacement-friendly serviceability.

Unique Advantages

• Proven high-temperature endurance — Rated to endure 3000 hours at 105 °C with rated ripple current, helping designs meet long-term stability requirements under heat stress.
• High ripple capability — Specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies support a range of switching and AC ripple conditions.
• Space-efficient can — One-rank smaller case size than the LGU series and compact dimensions aid in tighter PCB layouts without sacrificing capacitance.
• Robust mounting — Snap-in terminal provides mechanical stability for radial can installations and facilitates assembly and serviceability.
• Regulatory compliance — RoHS-compliant construction supports regulatory requirements for many modern electronic products.
