LGC2H331MELA55

The LGC2H331MELA55 is a snap-in terminal aluminum electrolytic capacitor designed for compact, long-life power applications. It combines a 330 µF capacitance with a 500 V rated voltage in an ultra-smaller-sized case (one rank smaller than LGX), making it suited for equipment downsizing and space-constrained designs.

Built for long-term reliability, this radial can snap-in capacitor is specified for operation from –40°C to +105°C and offers a 5000-hour endurance at 105°C, making it appropriate for general-purpose high-voltage DC applications where sustained performance is required.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 500 V rated voltage suitable for high-voltage DC circuits.
• High-temperature Long Life: Rated for operation to 105°C with an endurance specification of 5000 hours at 105°C under rated DC bias plus rated ripple current.
• Compact Snap-in Package: Radial, can-type snap-in mounting optimized for equipment downsizing — one rank smaller case than LGX to save board space.
• Ripple Current Performance: Rated ripple current of 1.78 A at 120 Hz (type value); frequency coefficient data is provided for higher frequencies (e.g., 1.43 at 50 kHz) to plan ripple handling across the spectrum.
• Reliability Parameters: Capacitance tolerance ±20% at 120 Hz/20°C; leakage current specified as I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ ≤ 0.25 at 120 Hz/20°C.
• Wide Operating Range: Specified operation from –40°C to +105°C with low-temperature stability (Z(–25°C)/Z(+20°C) ≤ 8 at 120 Hz).
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Compact power supplies: Provides bulk energy storage and smoothing in space-constrained AC/DC and DC/DC converters where 500 V capability and a small footprint are required.
• High-voltage DC filtering: Suited for high-voltage DC link and filtering duties up to the 500 V rating, benefiting designs that need long-term stability at elevated temperatures.
• Equipment downsizing and retrofits: The one-rank-smaller case size makes this capacitor a direct fit for redesigns targeting reduced enclosure and PCB real estate.
• General-purpose industrial electronics: Use in general-purpose circuits that require stable capacitance, controlled leakage, and reliable ripple handling across a broad temperature range.

Unique Advantages

• Space-saving design: One rank smaller than LGX, enabling reduced enclosure and PCB area for downsized equipment.
• High-voltage capability: 500 V rating supports high-voltage DC link and filtering requirements without parallel components.
• Long-life specification: 5000 hours at 105°C under rated conditions provides predictable service life for thermal-stressed applications.
• Quantified ripple handling: Published rated ripple currents and frequency coefficients allow accurate thermal and lifetime calculations under real operating spectra.
• Measurable reliability metrics: Clear leakage-current limit (I ≤ 3√CV), tan δ, and low-temperature impedance ratios facilitate engineering validation and BOM selection.
• RoHS compliant: Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances.
