LGN2V181MELA25

The LGN2V181MELA25 is a Nichicon LGN series aluminum electrolytic capacitor in a snap-in terminal radial can. It delivers 180 µF capacitance at a 350 V rating with a φ25 × 25 mm package designed for general-purpose high-voltage applications.

Engineered for sustained performance at elevated temperatures, this part offers a 3000-hour endurance at 105°C and ripple current ratings specified at both low and high frequencies, making it suitable where reliable high-voltage capacitance and long-term stability are required.

Key Features

• Rated Capacitance and Voltage — 180 µF nominal capacitance rated for 350 V operation (±20% tolerance), providing substantial charge storage for high-voltage circuits.
• Snap-in Radial Can Package — Snap-in terminal, radial can construction in a φ25 × 25 mm body for secure panel/PCB mounting and mechanical stability.
• High-Temperature Endurance — Designed to meet endurance requirements after 3000 hours at 105°C under D.C. bias plus rated ripple current; capacitance change remains within ±20% and leakage current stays at or below initial specified values.
• Loss and Leakage Characteristics — Maximum tan δ of 0.15 (measured at 120 Hz, 20°C) and leakage current specification I ≤ 3/√C µA after 5 minutes at 20°C, enabling predictable electrical behavior.
• Ripple Current Ratings — Rated ripple current of 900 mA at 120 Hz and 1.287 A at 100 kHz, supporting applications with significant AC ripple components.
• Operating Temperature Range — Specified for operation from −25°C to +105°C for the 350 V rating, aligning with the product’s 105°C endurance qualification.
• Compliance and Packaging — RoHS compliant and available in tray packing for mass production handling and assembly.
• Polarized Electrolytic Design — Polarized capacitor suitable for DC-biased circuits where polarized electrolytic capacitors are required.

Typical Applications

• General-purpose high-voltage power filtering — Provides bulk capacitance and ripple handling at 350 V for power systems requiring stable DC smoothing.
• Energy storage in DC circuits — 180 µF capacitance and rated ripple current support temporary energy buffering and decoupling in high-voltage DC networks.
• High-temperature environments — Rated for continuous operation and tested endurance at 105°C, suitable where elevated ambient temperatures are expected.

Unique Advantages

• 350 V rating for high-voltage designs: Enables use in circuits demanding higher working voltages without series stacking of components.
• Long endurance at elevated temperature: 3000 hours at 105°C assures predictable lifetime behavior under sustained thermal stress.
• Frequency-aware ripple performance: Specified ripple currents at both 120 Hz and 100 kHz allow evaluation for a range of power-conversion switching frequencies.
• Compact snap-in form factor: φ25 × 25 mm body in a snap-in can combines manageable PCB mounting with substantial capacitance for its size.
• Measurable electrical stability: Tight specifications for tan δ and leakage current (including a formula-based leakage limit) help ensure consistent selection and design validation.
• Production-friendly packaging: Tray packing and mass-production availability support volume assembly and procurement planning.
