LGC2H331MELC35

The LGC2H331MELC35 is a snap‑in terminal type aluminum electrolytic capacitor in Nichicon's LGC series, offering 330 µF capacitance at a 500 V rating. It combines a compact, large‑can snap‑in package that is one rank smaller than LGX with long‑life capability for general-purpose power applications.

Designed for equipment downsizing and robust operation, the LGC2H331MELC35 supports high‑voltage smoothing and energy storage where a space‑efficient snap‑in can is required. The series is RoHS compliant and rated for extended endurance at elevated temperature.

Key Features

• Rated Capacitance and Voltage: 330 µF nominal capacitance at a 500 V DC rating for high‑voltage energy storage and smoothing.
• Compact Snap‑in Package: Radial can with snap‑in terminals in a smaller case size than LGX, sized L: 3.5 × D: 3.5 cm for equipment downsizing.
• Long Life at High Temperature: Endurance specified for 5000 hours at 105°C when tested under rated DC bias plus rated ripple current.
• Operating Temperature Range: −40°C to +105°C to support a wide range of ambient conditions.
• Ripple Current Capability: Specified ripple currents include 1.63 A at 120 Hz and 2.331 A at 50 kHz for AC ripple handling across common frequencies.
• Electrical Characteristics: 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 (120 Hz, 20°C).
• Performance Stability: Low‑temperature impedance stability Z(−25°C)/Z(+20°C) ≤ 8 (120 Hz); endurance and shelf‑life limits defined in the series datasheet.
• Polarized Device: Polarized electrolytic design for DC applications requiring a polarity‑defined capacitor.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power supply smoothing: Energy storage and ripple suppression in high‑voltage DC power stages where a 500 V, 330 µF capacitor is appropriate.
• Equipment downsizing projects: Replacement or design‑in where a smaller can size than LGX helps reduce enclosure volume while retaining high voltage capability.
• Industrial and commercial power equipment: Applications requiring long endurance at elevated temperatures and robust ripple handling in a snap‑in form factor.

Unique Advantages

• Space‑efficient form factor: One rank smaller case than LGX enables reduced board and enclosure footprint without lowering voltage or capacitance.
• Engineered for high‑temperature life: 5000 hours endurance at 105°C supports longevity in thermally demanding systems.
• Broad frequency ripple handling: Published ripple current values at 120 Hz and 50 kHz allow designers to evaluate performance across common operating frequencies.
• Clear, measurable electrical limits: Leakage current, tan δ, and low‑temperature impedance ratios are specified, simplifying validation and thermal design.
• Snap‑in mounting for secure PCB installation: Radial snap‑in terminals provide mechanical stability for high‑current and high‑vibration environments.
• RoHS compliant: Meets lead‑restriction requirements for environments requiring regulatory conformity.
