LGC2H331MELB40

The LGC2H331MELB40 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for long-life operation and compact assemblies. It delivers 330 µF capacitance at 500 V with a polarized construction tailored for general-purpose power applications where equipment downsizing and high-temperature endurance are priorities.

Engineered for sustained operation up to 105°C, this ultra-smaller-sized member of the LGC series is RoHS compliant and intended for designers who need reliable bulk capacitance in a reduced case footprint.

Key Features

• Capacitance & Rated Voltage — 330 µF nominal capacitance at a rated voltage of 500 V, suitable for high-voltage bulk energy storage and filtering.
• High-temperature long life — Rated for operation from −40°C to +105°C with a guaranteed endurance of 5,000 hours at 105°C under D.C. bias plus rated ripple current.
• Compact snap-in package — Snap-in terminal, radial can construction in an ultra-smaller-sized case (one rank smaller than LGX), with a physical size listed as L: 4 × D: 3 cm for space-constrained designs.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized configuration for standard electrolytic applications.
• Ripple current capability — Rated ripple current of 1.67 A at 120 Hz and 2.388 A at 50 kHz, enabling effective handling of AC ripple in power circuits.
• Leakage and loss characteristics — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) up to 0.25 max at 120 Hz, 20°C.
• Stability and endurance data — Low-temperature impedance stability Z(−25°C)/Z(+20°C) ≤ 8 (120 Hz); endurance criteria include capacitance retention and leakage current limits after life and shelf-life tests per the series specification.
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in power supplies and DC link circuits where a polarized high-voltage capacitor is required.
• Compact industrial equipment — Suited for equipment downsizing efforts thanks to its ultra-smaller-sized case compared with LGX-style parts.
• High-temperature environments — Applications that demand long-term performance at elevated temperatures up to 105°C, including continuous-duty power electronics.

Unique Advantages

• Smaller footprint for downsized designs: One rank smaller case than LGX enables higher component density without sacrificing capacitance or voltage rating.
• High-voltage capability: 500 V rating provides high-voltage bulk energy storage in a single component, reducing component count.
• Long-life assurance at elevated temperature: 5,000-hour endurance at 105°C supports longevity in demanding thermal environments.
• Robust ripple handling: Specified ripple currents at both low and high frequencies (1.67 A at 120 Hz, 2.388 A at 50 kHz) help manage AC stress in power circuits.
• Reliable electrical characteristics: Defined leakage current limit and tan δ specification allow predictable performance and easier system design.
• RoHS-compliant construction: Meets current lead-free and restricted-substance requirements for global product markets.
