LNR1V683MSEN

The LNR1V683MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, delivering 68,000 µF (68 mF) at a rated voltage of 35 V in a φ51×80L radial can with screw terminals. Designed for general-purpose power applications, it provides high bulk capacitance and rugged screw-terminal mounting for secure electrical and mechanical connections.

Built to the LNR series’ 85°C standard, this part supports an operating temperature range of −40°C to +85°C and a rated endurance of 5,000 hours at 85°C, making it suitable for systems that require sustained bulk energy storage and reliable long-term performance.

Key Features

• Electrical Performance 68,000 µF (68 mF) capacitance at 35 V with ±20% tolerance; leakage current specified as ≤ 3√(C·V) µA or 5 mA (after 5 minutes at 20°C).
• Ripple Current Capability Handles 9.3 A ripple at 120 Hz and 10.7 A at 100 kHz, supporting significant AC ripple in power-conditioning applications.
• Thermal and Endurance Specification Rated for −40°C to +85°C operation and qualified for 5,000 hours at 85°C under DC bias plus rated ripple current; capacitance change after endurance is within ±15% and leakage current remains within initial limits.
• Robust Screw-Terminal Package Radial can with screw terminals (φ51 body) and standard 3-leg mounting bracket; terminal hardware accommodates M5 bolt mounting for secure connections.
• Mechanical Dimensions Compact high-capacitance form factor: body diameter φ51 mm and length 80 mm, suitable where high bulk capacitance is required in a screw-terminal package.
• Compliance RoHS compliant.

Typical Applications

• Power supply bulk storage — High capacitance and rated ripple current make this capacitor suitable for DC bus smoothing and bulk energy storage in equipment that accepts screw-terminal components.
• Power conditioning modules — Use where sustained ripple handling and long endurance at 85°C are required to stabilize supply rails.
• Industrial and general-purpose equipment — Appropriate for machinery and systems that require high-capacitance, screw-mounted electrolytic capacitors for reliable power performance.

Unique Advantages

• High bulk capacitance: 68,000 µF provides substantial energy storage in a single component, reducing BOM count for bulk filtering.
• Secure screw-terminal connection: Screw terminals and M5-compatible hardware enable robust electrical and mechanical mounting for high-current or vibration-prone environments.
• Designed for continuous operation at elevated temperature: Rated for −40°C to +85°C with endurance validated for 5,000 hours at 85°C under rated conditions, supporting long-term reliability.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 100 kHz allow designers to evaluate performance across common power frequencies.
• Series-level reliability data: Endurance and leakage specifications (capacitance drift and leakage limits after endurance testing) provide predictable behavior for system-level design.
• RoHS compliance: Conforms to RoHS requirements for restricted substances.
