LGN2P391MELY35

The LGN2P391MELY35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series, offering 390 µF capacitance at a 220 V rating in a compact φ20 × 35 mm can. Designed for general‑purpose electronic equipment, it combines high ripple‑current capability and extended high‑temperature endurance for demanding power applications.

Key attributes include operation from −40 °C to 105 °C, a rated life of 3000 hours at 105 °C under rated ripple current, low leakage current, and a snap‑in radial can package suited to through‑hole assemblies. The part is RoHS compliant and available in tray packing for production use.

Key Features

• Capacitance & Voltage: 390 µF nominal capacitance with a 220 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in 220 V systems.
• High‑temperature Endurance: Rated for operation to 105 °C with an endurance specification of 3000 hours at 105 °C when subjected to DC bias plus rated ripple current.
• Robust Ripple‑Current Performance: Low‑frequency ripple current of 1.34 A (120 Hz) and high‑frequency ripple current of 2.01 A (100 kHz) to support AC ripple handling across a range of operating frequencies.
• Low Leakage & Dissipation: Specified leakage current of 870 µA and a tan δ (DF) of 0.15 measured at 20 °C, 120 Hz for predictable loss characteristics.
• Snap‑in Radial Can Package: Snap‑in terminal configuration in a compact φ20 × 35 mm can (radial, snap‑in) for secure mechanical mounting in through‑hole assemblies.
• Operational Range & Reliability: Polarized aluminum electrolytic construction with an operating temperature range of −40 °C to 105 °C and life/shelf specifications consistent with long production use.
• Production Ready & RoHS Compliant: Mass production status with tray packing and compliance to RoHS (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power filtering: Bulk capacitance and ripple suppression for 220 V power systems where 390 µF and high ripple current capability are required.
• High‑temperature electronic assemblies: Use in equipment that must operate continuously at elevated temperatures up to 105 °C and where rated endurance (3000 h at 105 °C) is important.
• Through‑hole chassis and PCB designs: Snap‑in radial can package provides secure mechanical mounting for assemblies requiring robust through‑hole components.

Unique Advantages

• Designed for high ripple loads: Specified low‑ and high‑frequency ripple currents (1.34 A at 120 Hz and 2.01 A at 100 kHz) support a wide range of switching and line conditions.
• Extended high‑temperature life: 3000 hours endurance at 105 °C under rated conditions supports reliability in thermally demanding environments.
• Compact, secure mounting: φ20 × 35 mm snap‑in can reduces board footprint while providing stable mechanical anchoring in through‑hole designs.
• Predictable leakage and dissipation: Leakage current of 870 µA and tan δ of 0.15 (20 °C, 120 Hz) enable controlled standby losses and thermal planning.
• Production availability: Mass production status with tray packing simplifies procurement and assembly for volume applications.
• Regulatory compliance: RoHS compliance supports use in regions and programs that require restricted substance adherence.
