LGR2E681MELC35

The LGR2E681MELC35 is a snap-in, radial can aluminum electrolytic capacitor from Nichicon’s LGR Long Life Assurance series. It delivers 680 µF capacitance at a 250 V rating in a polarized, snap-in package designed for general-purpose electronic applications.

Designed for elevated-temperature operation, this part is specified for use up to 105°C and is qualified by the series’ long-life specification that endures 10,000 hours of rated ripple current at 105°C. It is RoHS compliant.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a 250 V rated voltage and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Long-life Endurance — Part of the LGR series specified to withstand 10,000 hours of rated ripple current at 105°C; after endurance the capacitor meets defined limits for capacitance change, tan δ, and leakage current.
• High-Temperature Operation — Operating temperature range from –40°C to +105°C, enabling use in applications requiring sustained elevated-temperature performance.
• Ripple Current Capability — Rated ripple current of 1.7 A at 120 Hz and 2.55 A at 50 kHz for this part, with series frequency coefficients provided for other frequencies.
• Leakage Current Specification — Leakage current governed by the datasheet formula I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C.
• Package and Mounting — Radial, can-type snap-in terminal package for secure PCB mounting and mechanical stability in assemblies.
• Regulatory Compliance — RoHS compliant per the provided directive references.

Typical Applications

• General-purpose electronic equipment — Suitable wherever a polarized aluminum electrolytic capacitor is required for general-purpose circuit functions in electronic assemblies.
• Power supply filtering and smoothing — 250 V rating and defined ripple current capability (1.7 A @120 Hz, 2.55 A @50 kHz) support smoothing and filtering roles in high-voltage circuits.
• Elevated-temperature environments — Rated for operation up to 105°C and specified for long-life endurance under ripple current, making it appropriate for applications that require sustained high-temperature performance.
• Panel and chassis-mounted power assemblies — Snap-in radial can package offers mechanical retention for assemblies where robust through-hole mounting is preferred.

Unique Advantages

• Proven long-life specification: Endurance defined at 10,000 hours at 105°C for ripple current application, providing a verifiable lifetime metric.
• High ripple handling: Explicit ripple current ratings at 120 Hz and 50 kHz allow designers to size capacitors to meet AC stress requirements.
• Wide operational temperature range: –40°C to +105°C rating supports use across a broad set of thermal conditions.
• Secure snap-in mounting: Radial snap-in can package helps ensure mechanical stability and ease of assembly in through-hole designs.
• Clear electrical limits: Datasheet-specified leakage current formula and tan δ limits provide measurable acceptance criteria for production and inspection.
• RoHS compliance: Meets the stated RoHS directive requirements for restricted substances.
