LNT2V681MSEFBB

The LNT2V681MSEFBB is a screw-terminal aluminum electrolytic capacitor rated at 350 V with 680 µF capacitance. It is a polar, radial can-style capacitor in the Nichicon LNT series designed for general-purpose high-voltage power applications that require a robust, serviceable connection and long operating life.

Key value comes from its 5,000-hour endurance at 105°C, low dissipation factor (tan δ 0.2), and measurable ripple-current capability, making it suitable for DC link and bulk energy storage duties in industrial power systems and other equipment that operate to +105°C.

Key Features

• Capacitance & Voltage: 680 µF at 350 V — provides substantial energy storage for high-voltage DC applications.
• Screw Terminal Mounting: Radial can with screw terminals for secure, serviceable electrical connections. For φ51 size the nominal bolt is M5.
• Operating Temperature Range: Specified for −25°C to +105°C, matching the LNT series 160–500 V category temperature characteristics.
• Endurance: 5,000 hours at 105°C under rated ripple current — designed for sustained high-temperature operation.
• Ripple Current Capability: 4.1 A at 120 Hz and 5.74 A at 100 kHz — supports moderate AC ripple handling in power circuits.
• Dissipation Factor (tan δ): 0.2 (specified) — indicative of controlled loss characteristics at the measurement conditions.
• Low-Temperature Impedance Stability: For the 160–500 V range, Z(−25°C)/Z(+20°C) ≤ 8, helping maintain performance in cooler environments.
• Tolerance & Polarization: ±20% capacitance tolerance; polarized device for correct DC installation.
• Package & Size: φ51 × 80L (approximately L: 8 cm × D: 5.1 cm) in a radial can with screw terminals.
• Compliance & Manufacturing: RoHS compliant, packaged in cardboard, and listed as mass production status.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing on high-voltage DC rails where a 350 V, high-capacitance screw-terminal capacitor is required.
• Inverters and Motor Drives: DC-link smoothing and ripple mitigation benefiting from the part’s rated ripple current and high-temperature endurance.
• Power Conversion Systems: Energy buffering and transient suppression in medium-voltage converters and power-conditioning equipment.

Unique Advantages

• High-Voltage Energy Storage: 350 V rating with 680 µF capacitance provides substantial charge capacity for DC-link and bulk filtering needs.
• Secure, Serviceable Connections: Screw-terminal design with M5 nominal bolt (φ51) enables robust mechanical and electrical fastening for high-current or field-serviceable installations.
• Long High-Temperature Life: 5,000 hours at 105°C under rated ripple current supports durability in demanding thermal environments.
• Measured Ripple Performance: Specified ripple currents (4.1 A at 120 Hz; 5.74 A at 100 kHz) allow designers to assess thermal and ripple handling against system requirements.
• Controlled Dissipation: tan δ of 0.2 helps manage power loss and heating within the capacitor under normal measurement conditions.
• Regulatory Compliance & Production Readiness: RoHS compliance and mass-production availability simplify procurement and lifecycle planning.
