LGN2E391MELZ35

The LGN2E391MELZ35 is an aluminum electrolytic capacitor in a snap‑in terminal configuration designed for general-purpose electronic applications. It combines a compact, smaller-sized case profile with robust thermal and ripple-current endurance for reliable performance in board-mounted power circuitry.

Key attributes include a 390 µF capacitance at 250 V rating, rated operation to 105°C, and endurance for 3000 hours under rated ripple current at 105°C. The part is RoHS compliant and uses a snap‑in radial can package for secure PCB mounting.

Key Features

• Capacitance and Voltage: 390 µF nominal capacitance with a 250 V rated voltage, suitable where mid-range bulk capacitance and voltage handling are required.
• Tolerance: ±20% capacitance tolerance at 120 Hz, 20°C, providing predictable filtering and energy storage behavior.
• Temperature Range: Operates from −40°C to +105°C, supporting elevated-temperature environments within the specified range.
• Endurance at High Temperature: Specified to withstand 3000 hours of application of rated ripple current at 105°C, meeting longevity requirements for sustained high-temperature operation.
• Ripple Current Capability: Rated ripple current of 1.3 A at 120 Hz and 1.95 A at 100 kHz, enabling effective smoothing under AC and switching conditions.
• Package & Mounting: Snap‑in terminal, radial can package (L: 3.5 × D: 2.2 cm) designed for secure snap‑in PCB mounting; one rank smaller case size than LGU-series equivalents.
• Polarized Design: Polarized electrolytic construction for DC smoothing and bulk energy applications.
• Regulatory Compliance: Compliant with RoHS directive (2011/65/EU, (EU)2015/863), supporting restricted-substances requirements.

Typical Applications

• General‑Purpose Power Supplies — Bulk filtering and smoothing in power rails where 250 V rating and 390 µF capacitance are required.
• Industrial Electronics — Board-mounted energy storage and decoupling in industrial equipment operating up to 105°C ambient.
• Switching Power Converters — Ripple filtering in converters and rectifier outputs, taking advantage of the specified ripple current ratings at 120 Hz and 100 kHz.

Unique Advantages

• Compact, space-saving package: One rank smaller case size than LGU-series parts, enabling higher density board designs without sacrificing capacitance.
• Sustained high-temperature reliability: Endurance tested for 3000 hours at 105°C under rated ripple current, delivering predictable long-term performance in elevated-temperature applications.
• Dual-frequency ripple capability: Rated ripple currents provided for both low (120 Hz) and high (100 kHz) frequencies, simplifying selection for mixed-frequency power systems.
• Snap‑in mounting for secure installation: Radial, snap‑in can package ensures robust mechanical retention on PCBs for through‑hole assemblies.
• Regulatory alignment: RoHS compliance helps meet environmental and product compliance requirements in regulated markets.
