LGU2F271MELA

The LGU2F271MELA is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power electronics. It provides 270 µF capacitance at a 315 V rating in a compact φ25 × 35 mm can, delivering high ripple-handling and long-term endurance for demanding DC applications.

Key value comes from its 3000-hour endurance at 105°C, low loss (tan δ = 0.15 at 20°C, 120 Hz), and measured ripple-current capability at both low and high frequencies—attributes that support reliable bulk filtering and energy buffering in industrial and power systems.

Key Features

• Rated Voltage & Capacitance — 315 V nominal rating with 270 µF capacitance and ±20% tolerance for bulk energy storage and DC voltage support.
• Snap-in Terminal Package — Radial, can-type snap-in mounting for secure PCB installation and high-current connection in through-hole assemblies.
• High Temperature Endurance — Specified for 3000 hours at 105°C with DC bias plus rated ripple current, supporting long-term operation in elevated-temperature environments.
• Ripple Current Performance — 1.16 A at 120 Hz (low frequency) and 1.659 A at 50 kHz (high frequency), enabling effective smoothing under AC ripple and switching conditions.
• Low Dissipation Factor — tan δ = 0.15 (max) measured at 20°C and 120 Hz, indicating low dielectric loss for improved efficiency.
• Low Leakage Current — 870 µA specified leakage current after rated voltage application, supporting predictable standby and DC performance.
• Operating Temperature Range — Rated for −25°C to +105°C to accommodate a wide range of industrial ambient conditions.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing in high-voltage supply rails where 315 V rating and high ripple capability are required.
• DC Link / Energy Buffering — DC link and intermediate energy storage for converters and inverters benefiting from the capacitor's high voltage rating and endurance at 105°C.
• Power Conditioning — Ripple suppression and energy decoupling in UPS modules and power-conditioning equipment that demand stable performance under sustained ripple current.
• Motor Drives and Inverters — Support for switching loads where both low-loss dielectric behavior (tan δ) and measured high-frequency ripple current are important.

Unique Advantages

• High-voltage capability: 315 V rating lets designers use a single capacitor for higher-voltage DC systems, simplifying BOM and layout.
• Long-term reliability at elevated temperature: 3000 hours endurance at 105°C under rated ripple current provides documented life performance for longer maintenance intervals.
• Measured ripple performance across frequencies: Specified ripple-current values at 120 Hz and 50 kHz enable confident thermal and lifetime calculations for both line-frequency and switching applications.
• Low dissipation and controlled leakage: tan δ = 0.15 and 870 µA leakage current support efficient energy use and predictable leakage budgets in system designs.
• Robust snap-in packaging: Radial snap-in can delivers secure mechanical retention and high-current PCB connections for through-hole assemblies.
• RoHS compliant manufacturing: Aligns with environmental requirements for commercial and industrial products.
