LGL2G271MELA30

The LGL2G271MELA30 is a snap-in terminal aluminum electrolytic capacitor optimized for high-voltage, general-purpose power applications. It delivers 270 µF at 400 V in a compact 25 mm × 30 mm can and is designed for reliable long-term performance with a rated operating temperature range of −25°C to 105°C.

With a 2000-hour endurance at 105°C, low loss (tan δ ≤ 0.15 at 20°C/120 Hz), and validated ripple-handling capability across frequencies, this part is suited for bulk smoothing, DC-link, and other high-voltage reservoir applications that demand compact size and robust thermal endurance.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 400 V; ±20% tolerance (120 Hz, 20°C).
• Snap-in Radial Can — Snap-in terminal type in a radial can package for secure mounting and ease of assembly in power modules.
• Temperature & Endurance — Operating range −25°C to 105°C with 2000 hours life at 105°C under rated DC bias plus rated ripple current.
• Low Loss — tan δ ≤ 0.15 (max) measured at 120 Hz and 20°C, supporting efficient energy storage and reduced self-heating.
• Leakage Specification — Specified leakage current of 980 µA; datasheet provides the leakage limit formulation I ≤ 3√(C·V) after 5 minutes at 20°C.
• High Ripple Capability — Rated ripple current of 910 mA at 120 Hz and 1.301 A at 50 kHz, enabling stable performance across common power-conversion frequencies; frequency coefficients are provided for other operating frequencies.
• Compact Dimensions — Physical size approximately 25 mm diameter × 30 mm length (L: 3 × D: 2.5 cm), enabling tighter packing in high-voltage assemblies.
• Production & Packaging — Tray packing and mass production status support volume manufacturing and streamlined procurement.

Typical Applications

• 400 V Power Supplies — Bulk smoothing and energy reservoir in 400 V rails where high-voltage capacitance and ripple handling are required.
• DC-Link and Inverter Systems — DC-link decoupling and pulse-current buffering in power conversion modules using the part’s rated voltage and ripple capability.
• Industrial Power Electronics — General-purpose filtering and energy storage in industrial converters and power-conditioning equipment operating up to 105°C.

Unique Advantages

• High-Voltage, Compact Form — 400 V rating in a 25 mm × 30 mm can lets designers reduce board area without sacrificing voltage capability.
• Validated Thermal Endurance — 2000 hours at 105°C ensures durability for extended operation in thermally demanding environments.
• Frequency-Aware Ripple Performance — Rated ripple values at 120 Hz and 50 kHz, plus frequency coefficients, give predictable behavior across common switching frequencies.
• Low Dissipation Factor — tan δ ≤ 0.15 at 120 Hz supports lower self-heating and consistent AC performance.
• Assembly-Friendly Mounting — Snap-in terminals provide reliable mechanical retention for power assemblies and simplify placement during production.
• Production-Ready Packaging — Tray packing and mass-production availability support cost-effective sourcing for large-volume programs.
