LGA2W271MELA40

The LGA2W271MELA40 is a snap‑in, radial-can aluminum electrolytic capacitor rated at 270 µF and 450 V. It is designed for general purpose applications that require high capacitance and high ripple-handling in a robust, long‑life package.

Key value propositions include a 105°C operating range, proven endurance of 5000 hours under rated ripple at 105°C, and RoHS compliance for regulated environments.

Key Features

• Capacitance & Voltage — 270 µF capacitance with a 450 V rated voltage, suitable for high-voltage DC applications within the specified rating.
• High Ripple Current & Endurance — Rated ripple current of 1.77 A at 120 Hz and proven to withstand 5000 hours of rated ripple current at 105°C, supporting sustained high-stress operation.
• Wide Operating Temperature — Specified operating range from −40°C to 105°C for use across a wide thermal envelope.
• Low ESR — Equivalent series resistance of 1.105 mΩ at 120 Hz, enabling efficient ripple dissipation and reduced self-heating under load.
• Package & Mounting — Radial, snap‑in can package (snap‑in terminal type) for secure PCB mounting and mechanical stability.
• Quality & Compliance — Long-life endurance specification and compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — High‑voltage DC circuits — Provides bulk capacitance at 450 V where robust energy storage and smoothing are required within the rated limits.
• General Purpose — Ripple suppression — Handles specified ripple currents (1.77 A at 120 Hz; 2.531 A at 50 kHz) for filtering and stabilization under continuous load.
• General Purpose — Long-life power systems — Endurance rating of 5000 hours at 105°C supports applications that require sustained operation at elevated temperatures.

Unique Advantages

• Demonstrated long-life endurance: Withstands 5000 hours of rated ripple current at 105°C, offering predictable performance over prolonged high-temperature service.
• High-voltage capability: 450 V rating enables use in higher-voltage DC circuits while maintaining the specified capacitance of 270 µF.
• Efficient thermal performance: Low ESR (1.105 mΩ at 120 Hz) reduces power dissipation and helps control temperature rise under ripple loading.
• Snap‑in radial package: Robust can and snap‑in terminals provide reliable mechanical mounting and straightforward PCB integration.
• Regulatory compliance: RoHS compliance supports deployment in designs requiring restricted-substance adherence.
