LGN2H331MELC45

The LGN2H331MELC45 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose high‑voltage applications. It combines a 330 µF capacitance with a 500 V rated voltage in a smaller‑sized snap‑in can, delivering high ripple endurance and extended operation at elevated temperatures.

Engineered for applications that require sustained performance at up to 105°C, this part offers long endurance under rated ripple current and is RoHS‑compliant for environmental standards.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 500 V rated voltage, suitable for high‑voltage electrolytic capacitor requirements.
• High‑temperature Endurance: Rated operating temperature range of −25°C to +105°C with endurance specified as 3000 hours at 105°C under DC bias plus rated ripple current.
• Snap‑in Terminal Package: Radial, can‑type snap‑in mounting for secure board attachment and reliable mechanical connection in high‑power assemblies.
• Ripple Current Capability: Specified ripple current of 1.25 A at 120 Hz and 1.788 A at 100 kHz, supporting applications with continuous AC ripple stress at the rated voltage.
• Leakage and Loss Characteristics: Leakage current conforms to the datasheet formula I ≤ 3/√C µA (measured after 5 minutes at 20°C); specified tan δ limits per rated voltage bands are provided in the LGN series datasheet.
• Compact, Smaller Case Size: One rank smaller case size compared to the LGU series, enabling denser packing where space is constrained.
• Polarized Electrolytic Design: Polarized construction with ±20% capacitance tolerance at 120 Hz, 20°C, for predictable bulk capacitance in DC applications.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for environmental regulatory requirements.

Typical Applications

• General‑purpose power supplies — Smoothing and bulk energy storage where a 500 V rated, high‑capacitance capacitor with defined ripple current capability is required.
• High‑voltage power circuits — Use in circuits that require 500 V dielectric rating and high ripple endurance at elevated temperature.
• Environments with elevated operating temperature — Systems requiring reliable operation up to 105°C and endurance of 3000 hours under rated ripple conditions.
• Applications needing compact high‑voltage capacitors — One‑rank smaller case size than LGU enables space‑efficient layouts without sacrificing rated voltage or endurance.

Unique Advantages

• Long high‑temperature life: Endurance specified at 3000 hours at 105°C ensures sustained performance in hot operating environments.
• Defined ripple performance: Published ripple current values at both 120 Hz and 100 kHz allow designers to size capacitors against measured ripple in the target circuit.
• Space savings: One rank smaller case size than LGU helps reduce board footprint while maintaining high voltage and capacitance.
• Robust mounting: Snap‑in terminal package provides a secure mechanical connection for heavy current and vibration conditions common in power equipment.
• Regulatory compliance: RoHS conformity supports deployment in products requiring restricted substance compliance.
• Predictable electrical characteristics: Specified tolerance (±20%), leakage current formula, and tan δ limits enable precise design margining and reliability planning.
