LGN2D391MELY30

The LGN2D391MELY30 is an aluminum electrolytic capacitor in a snap-in terminal radial can package, designed for general-purpose electronic applications. It delivers 390 µF at a 200 V rating with a compact, smaller-sized case profile (one rank smaller than LGU) and is specified for continuous use from –40°C to 105°C.

Key value propositions include a long endurance under elevated temperature and ripple conditions (3000 hours at 105°C with rated ripple), industry-standard snap-in mounting for robust PCB installation, and RoHS compliance.

Key Features

• Electrical Rating — 390 µF nominal capacitance at 200 VDC provides significant bulk capacitance for energy storage and smoothing in general-purpose circuits.
• High-Temperature Endurance — Rated for operation from –40°C to 105°C with an endurance specification of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Performance — Specified ripple ratings of 1.34 A at 120 Hz and 2.01 A at 100 kHz support applications with substantial AC ripple content.
• Snap-In Radial Can Package — Snap-in terminal type in a radial, can-style package for secure mechanical mounting and easy assembly into power modules and assemblies.
• Leakage and Dielectric Characteristics — Series specification for leakage current: I ≤ 3/√(C) µA after 5 minutes’ application of rated voltage at 20°C; tan δ limits and impedance stability are defined by the LGN series datasheet.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics — Suitable for assemblies requiring reliable bulk capacitance in a compact snap-in format for ease of installation.
• High-Temperature Operation — For designs that require sustained performance up to 105°C and verified endurance (3000 hours at 105°C under rated ripple and bias).
• High-Ripple Current Circuits — Appropriate where significant ripple handling is needed, backed by rated ripple current data at 120 Hz and 100 kHz.

Unique Advantages

• Smaller Case Footprint — One rank smaller case size than the LGU series lets designers reduce board area while maintaining rated capacitance.
• Proven High-Temperature Endurance — Endurance tested for 3000 hours at 105°C with D.C. bias plus rated ripple current, supporting reliable long-term operation in elevated-temperature environments.
• Robust Ripple Capability — Published ripple current specifications at both low and high frequencies (120 Hz and 100 kHz) simplify thermal and lifetime planning.
• Secure Snap-In Mounting — Snap-in terminals in a radial can package provide reliable mechanical retention for power assemblies and modules.
• RoHS Compliance — Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for environmental and regulatory requirements.
• Measured Electrical Limits — Leakage and tan δ parameters are defined by the LGN series specifications to support predictable electrical behavior after voltage application and aging.

Why Choose LGN2D391MELY30?

LGN2D391MELY30 is positioned for designers seeking a compact, high-capacitance aluminum electrolytic with verified endurance at elevated temperatures and clear ripple-current specifications. Its snap-in radial can package and RoHS compliance make it a practical choice for assembly into general-purpose power and electronic systems where mechanical stability and long-term thermal performance matter.

This part suits projects requiring predictable lifetime behavior under rated ripple and bias, and it supports design decisions where smaller case size, high-temperature endurance, and defined electrical limits reduce uncertainty during qualification and production.
