LNT1E683MSE

The LNT1E683MSE is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series. It provides 68,000 µF of capacitance at a 25 V rating in a radial can with screw terminals, designed for general‑purpose power applications that require large bulk capacitance and robust terminal connections.

Key engineered attributes include a wide operating temperature range of −40°C to +105°C, a rated endurance of 2,000 hours at 105°C, and high ripple current capability at both low and high frequencies—making it suitable where sustained DC bias and ripple handling are required.

Key Features

• High Capacitance: 68,000 µF (68 mF) nominal capacitance for bulk energy storage and smoothing of power rails.
• 25 V Rated Voltage: Designed for 25 V DC systems where high bulk capacitance is required.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low‑impedance connections for high current applications.
• High Ripple Current Capability: Low‑frequency ripple current 10.2 A (120 Hz) and high‑frequency ripple current 11.73 A (100 kHz), supporting demanding AC ripple environments.
• Endurance at Elevated Temperature: 2,000 hours lifetime at 105°C under rated ripple current and DC bias.
• Temperature Range and Reliability: Rated for −40°C to +105°C operation with capacitance tolerance of −20% to +20% and a dissipation factor (tan δ) of 0.5 (measured at 20°C, 120 Hz).
• Physical Size & Package: Dimensions φ51 × 120 mm (L: 12 × D: 5.1 cm) and radial can package with screw terminals for secure mounting and ease of assembly.
• Leakage Current: Specified leakage current of 3,910 µA for predictable quiescent current characteristics.
• RoHS Compliant: Meets RoHS environmental requirements as documented in product data.

Typical Applications

• General Purpose Power Systems: Use as bulk capacitance for DC bus smoothing and energy buffering where high capacitance and screw‑terminal connections are required.
• Power Supply Filtering: Effective for filtering ripple at both low (120 Hz) and high (100 kHz) frequencies thanks to rated ripple current values of 10.2 A and 11.73 A respectively.
• Industrial Electronics: Suitable where robust terminal attachment and operation across −40°C to +105°C are needed for stable long‑term performance.

Unique Advantages

• Large Bulk Storage in a Compact Can: 68,000 µF in a φ51 × 120 mm package minimizes board area compared with multiple smaller capacitors.
• Secure High‑Current Connections: Screw terminals provide reliable, low‑impedance terminations for high ripple and DC currents.
• Broad Operating Temperature: −40°C to +105°C rating supports a wide range of environmental conditions without derating outside these limits.
• Engineered Endurance: 2,000 hours at 105°C under rated conditions gives predictable long‑term behavior in hot operating environments.
• Dual‑Frequency Ripple Capability: Specified ripple current at both 120 Hz and 100 kHz ensures performance across common power system frequencies.
