LGN2C272MELC45

The LGN2C272MELC45 is an aluminum electrolytic capacitor in a radial snap-in can designed for general-purpose applications. It combines a 2.7 mF capacitance with a 160 V rated voltage in a smaller-sized snap-in case, offering a compact solution where sustained ripple handling and elevated-temperature endurance are required.

Built for continuous operation up to 105°C, this capacitor is specified to withstand 3000 hours of rated ripple current at 105°C, making it suitable for designs that demand long-term stability under thermal and ripple stress. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — Rated capacitance of 2.7 mF with a rated voltage of 160 V, providing significant bulk capacitance in a snap-in package.
• High-Temperature Endurance — Endurance specified for 3000 hours at 105°C under D.C. bias plus rated ripple current, with capacitance change, tan δ and leakage current limits defined by the datasheet.
• Ripple Current Performance — Rated ripple current capability of 3.1 A at 120 Hz and 4.65 A at 100 kHz, supporting designs with sustained ripple load.
• Temperature Range — Operating temperature from −40°C to +105°C (per product specifications), supporting operation in elevated-temperature environments.
• Compact Snap-in Package — Radial, can-style snap-in mounting with physical size L: 4.5 × D: 3.5 cm and a smaller case size than the LGU series, enabling space-efficient board or rack layouts.
• Polarized Electrolytic — Polarized capacitor suitable for DC applications where polarity is observed; capacitance tolerance ±20%.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — For devices requiring 2.7 mF at 160 V in a snap-in can, specified for long-term operation at elevated temperature.
• High‑Ripple Environments — Where sustained ripple current handling is needed; specified ripple currents are 3.1 A at 120 Hz and 4.65 A at 100 kHz.
• Compact Power Assemblies — One rank smaller case than LGU and radial snap-in mounting help save space in power racks or chassis-mounted modules.

Unique Advantages

• Proven High-Temperature Endurance: Specified to withstand 3000 hours at 105°C under rated ripple current, supporting long-life use in thermally demanding installations.
• Strong Ripple Capability: Explicit ripple current ratings at both low and high frequencies enable predictable thermal and electrical design margins.
• Space-Efficient Footprint: Smaller-sized case than the LGU series and radial snap-in termination reduce board and chassis space requirements.
• Robust Operating Range: −40°C to +105°C operating range addresses a wide set of general-purpose use cases where elevated ambient temperatures occur.
• RoHS Compliance: Meets RoHS requirements (2011/65/EU, (EU)2015/863) for environmental and regulatory considerations.
• Clear Electrical Specification Set: Defined capacitance tolerance (±20%) and performance limits after endurance make it straightforward to validate in design tests.
