LGN2D331MELY30

The LGN2D331MELY30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGN series. It delivers 330 µF capacitance at a 200 V rating in a compact φ20 × 30 mm can with snap-in mounting for secure board attachment.

Designed for general-purpose applications that require high ripple handling and elevated temperature endurance, the part combines high-frequency and low-frequency ripple capability with a 3000-hour endurance rating at 105°C for sustained operation in demanding environments.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a 200 V rated voltage with ±20% tolerance.
• High-temperature Endurance — Endurance rated for 3000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Snap-In Mounting — Snap-in terminal type in a radial can package for reliable mechanical retention on PCBs.
• Ripple Current Capability — Low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 1.8 A (100 kHz), supporting both mains-frequency smoothing and higher-frequency decoupling.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.15 (measured at 20°C, 120 Hz) for predictable dissipation characteristics.
• Leakage Current — Rated leakage current of 770 µA (measured after application of rated voltage at 20°C).
• Operating Temperature Range — −40°C to +105°C, supporting elevated-temperature system designs.
• Compact Case & Packaging — φ20 × 30 mm can size (3 × 2 cm) supplied in tray packing; part is in mass production and RoHS compliant.

Typical Applications

• General-Purpose Power Electronics — For circuits requiring 330 µF / 200 V bulk capacitance in a snap-in can with proven high-temperature endurance.
• Power Supply Filtering — Suitable where combined low- and high-frequency ripple handling (1.2 A @120 Hz; 1.8 A @100 kHz) and long life at 105°C are needed.
• Industrial and Equipment Electronics — Fits designs that require robust, polarized aluminum electrolytic capacitors with tray packing for production assembly.

Unique Advantages

• Long 105°C Endurance: 3000 hours rated life at 105°C under DC bias plus rated ripple current supports longer maintenance intervals and reliability planning.
• Dual-Frequency Ripple Performance: Specified ripple currents at 120 Hz and 100 kHz provide quantifiable performance for both low- and high-frequency ripple scenarios.
• Compact Snap-In Form Factor: φ20 × 30 mm can with snap-in terminals offers a smaller footprint in the LGN family while maintaining radial can robustness.
• Predictable Dissipation: tan δ max of 0.15 (20°C, 120 Hz) helps designers estimate ESR-related heating and losses.
• Production-Ready Packaging: Tray packing and mass-production status simplify procurement and assembly logistics.
• RoHS Compliant: Conforms to RoHS directive requirements for regulated substances.
