LGN2E681MELB30

The LGN2E681MELB30 is a Nichicon LGN-series aluminum electrolytic capacitor in a snap-in terminal radial can. It delivers 680 µF nominal capacitance at a 250 V rating and is polarized for DC applications.

Designed for general-purpose use, this smaller-sized snap-in part offers high-temperature endurance and robust ripple-current capability for designs that require durable bulk capacitance in a compact package.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 250 V rated voltage with ±20% tolerance, suitable where substantial bulk capacitance is required.
• High-Temperature Endurance — Rated for operation up to 105°C and specified to withstand 3000 hours of rated ripple-current application at 105°C.
• Ripple Current Performance — Rated ripple current of 1.7 A at 120 Hz and 2.55 A at 100 kHz, supporting applications with continuous AC ripple loading.
• Snap-In Radial Can Package — Snap-in terminal mounting simplifies board assembly for through-hole designs; the part is one rank smaller in case size than the LGU series.
• Operating Temperature Range — Specified for −40°C to +105°C operation, enabling use across a wide thermal range.
• Regulatory Compliance — Compliant to RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose circuits — For designs that require 680 µF at 250 V with snap-in mounting and 105°C endurance.
• High-temperature environments — Where continuity of rated ripple handling at elevated ambient temperature is necessary.
• Through-hole power assemblies — Suitable for assemblies that use snap-in radial cans to secure bulk capacitance on the PCB.

Unique Advantages

• Durable ripple endurance: Proven to withstand 3000 hours of rated ripple current at 105°C, providing predictable long-term performance under continuous ripple loading.
• Compact snap-in form factor: One rank smaller case size than LGU-series parts, enabling more compact board layouts without sacrificing capacitance.
• High ripple-current capability: Explicit ratings at both low and high frequencies (1.7 A at 120 Hz and 2.55 A at 100 kHz) help designers select appropriate parts for AC-loaded DC circuits.
• Wide operating temperature: −40°C to +105°C rating supports use across a broad range of thermal conditions.
• RoHS compliant: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for reduced hazardous substances.
• Trusted manufacturer and series: Part of Nichicon’s LGN series, providing consistent specification and sizing across the family.
