LGY2A272MELB45

The LGY2A272MELB45 is a Nichicon LGY-series aluminum electrolytic capacitor in a snap-in radial can designed for high-reliability power applications. It provides 2.7 mF (2700 µF) capacitance at a 100 V rating with polarized terminals and tray packing for mass production.

Designed for industrial power supplies and ballast applications, this capacitor offers long-life assurance with endurance at elevated temperature, making it suitable where dependable smoothing, bulk energy storage and sustained ripple handling are required.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 100 V rated voltage and ±20% tolerance.
• High-Temperature Long Life — Endurance specified as 5000 hours at 105°C under rated ripple and DC bias conditions.
• Operating Temperature Range — Specified for –40°C to +105°C operation for thermal robustness in industrial environments.
• Ripple Current Capability — Rated ripple: 2.4 A at 120 Hz and 2.76 A at 50 kHz; frequency coefficients apply across frequency ranges (e.g., 0.88 at 50 Hz, 1.00 at 120 Hz, 1.15 at 1 kHz and above).
• Leakage Current Specification — Leakage current limited to I ≤ 3√(C·V) μA after 5 minutes' application of rated voltage at 20°C (C in μF, V in V).
• Mounting & Package — Snap-in terminal, radial can package (φ30 × 45 mm / L: 4.5 × D: 3 cm) for secure board retention and efficient installation in production.
• Polarized — Designed for polarized DC applications requiring reliable polarity handling.
• RoHS Compliant — Complies with RoHS directives as stated in the product data.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy storage where elevated temperature endurance (5000 h at 105°C) and 100 V rating support reliable operation under sustained load.
• Ballasts — Suited for ballast circuits that require long-life capacitors able to tolerate continuous ripple current and high temperature.
• General Purpose Power Filtering — Smoothing and decoupling in general-purpose power systems that need high capacitance and robust ripple performance.

Unique Advantages

• Proven Long-Life Endurance: 5000 hours at 105°C under rated ripple and DC bias provides predictable degradation characteristics for long-term designs.
• High Capacitance at High Voltage: 2700 µF at 100 V supports substantial bulk energy storage in a compact snap-in can.
• Broad Operating Temperature Range: –40°C to +105°C enables deployment across a wide range of industrial environments.
• Frequency-aware Ripple Performance: Published ripple current ratings and frequency coefficients allow engineers to size the capacitor for application-specific ripple spectra.
• Production-friendly Packaging: Tray packing and snap-in mounting facilitate automated assembly and reliable mechanical retention in mass-production environments.
• Measurable Leakage Limit: Leakage current defined by I ≤ 3√(C·V) μA gives a verifiable criterion for leakage behavior after voltage application.
