LGN2G271MELZ50

The LGN2G271MELZ50 is a snap-in terminal type aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 270 µF capacitance at a 400 V rating in a smaller-sized, radial can package and is compliant with RoHS requirements.

Engineered for elevated-temperature operation, this capacitor is specified for operation up to 105°C and is rated to withstand 3000 hours of applied rated ripple current at 105°C, making it suited to demanding, continuous-duty environments where a compact, high-voltage electrolytic solution is required.

Key Features

• Capacitance & Voltage — 270 µF capacitance at a 400 V rated voltage for high-voltage bulk energy and filtering needs.
• High-Temperature Endurance — Rated for operation up to 105°C with a specified lifetime of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Capability — Rated ripple current of 1.22 A at 120 Hz and 1.745 A at 100 kHz for continuous ripple handling across common power frequencies.
• Compact Snap-In Package — Radial, can-type snap-in mounting provides secure board attachment and a one-rank-smaller case size compared to LGU-series parts to save PCB space.
• Electrical Characteristics — Polarized capacitor with ±20% capacitance tolerance and leakage current specification I ≤ 3/√C after standard warm-up.
• Operating Range — Specified operating temperature range of −25°C to 105°C for a variety of general-purpose environments.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• General-purpose power electronics — Bulk smoothing and energy storage in general-purpose equipment that requires a compact 400 V electrolytic capacitor.
• Power supplies — Use where sustained ripple current and high-voltage filtering are needed within a constrained footprint.
• Industrial equipment — Applications requiring robust high-temperature endurance and reliable snap-in mounting for secure installation.

Unique Advantages

• Compact high-voltage solution: One-rank-smaller case than LGU-series parts reduces PCB space while retaining 400 V capability.
• Extended high-temperature durability: 3000-hour endurance at 105°C under rated ripple current supports sustained operation in warm environments.
• Reliable snap-in mounting: Radial can with snap-in terminals provides secure mechanical attachment for stable long-term use.
• Measurable ripple performance: Specified ripple current at both 120 Hz (1.22 A) and 100 kHz (1.745 A) lets designers evaluate performance across relevant frequencies.
• Regulatory compliance: RoHS compliance supports deployments where restricted substances compliance is required.
