LNT2H681MSEFBB

The LNT2H681MSEFBB is an aluminum electrolytic capacitor in Nichicon’s LNT series designed for screw-terminal, radial-can installations. It provides 680 µF of capacitance at a 500 V rating with polarized terminals and is RoHS compliant.

Engineered for general-purpose high-voltage applications, this capacitor delivers high ripple-current handling and extended temperature capability to support demanding power systems and industrial equipment that require robust, high-voltage bulk capacitance.

Key Features

• High Voltage Rating — 500 V rated voltage suitable for high-voltage power circuits.
• Large Capacitance — 680 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and smoothing.
• Screw Terminal Package — Radial can with screw terminals for secure, low-resistance connections in panel- or chassis-mounted power assemblies.
• High Ripple Current Capability — Rated ripple currents of 4.2 A at 120 Hz and 5.88 A at 100 kHz to support continuous AC ripple conditions.
• Elevated Temperature Endurance — Operates from −25°C to +105°C and specified lifetime of 2000 hours at +105°C for 500 V applications.
• Polarized Design — Electrolytic, polarized construction for DC bulk capacitance applications.
• RoHS Compliant — Meets RoHS directive requirements as indicated for the LNT series.
• Physical Size — Compact radial can (L: 10.0 cm × D: 5.1 cm) with a maximum seated height of 3.937 inches for space-aware mechanical design.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage where a 500 V rated capacitor is required.
• Industrial power systems — Filtering and ripple absorption in equipment that demands high ripple-current capability and reliable screw-terminal connections.
• Commercial electrical equipment — General-purpose DC-link and smoothing in systems operating up to +105°C ambient temperatures.

Unique Advantages

• High-voltage capability: 500 V rating enables use in elevated-voltage designs without parallel capacitor networks.
• Robust ripple performance: Specified ripple currents at 120 Hz and 100 kHz reduce the need for oversized margins in ripple-heavy circuits.
• Screw-terminal reliability: Radial can with screw terminals simplifies secure, mechanically robust connections for field- or factory-installed systems.
• Temperature and life data: Specified operating range of −25°C to +105°C and 2000 hours endurance at +105°C (for this voltage) provide clear design margins for thermal endurance planning.
• RoHS compliance: Meets environmental regulations for lead-free manufacturing and deployment.
• Clear electrical tolerance: ±20% capacitance tolerance at 120 Hz, 20°C supports predictable performance in filter and energy-storage designs.
