LNT2H681MSEFBN

The LNT2H681MSEFBN is a screw-terminal aluminum electrolytic capacitor designed for high-voltage, high-temperature general-purpose applications. It delivers 680 µF capacitance at a 500 V rating with screw-terminal mounting for robust electrical and mechanical connections.

Engineered for elevated operating conditions, this part supports up to +105°C operation and a specified load life of 2000 hours at 105°C for the 500 V rating, making it suitable for demanding power systems that require bulk energy storage and high ripple handling.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 500 V rated voltage for high-voltage DC applications where significant energy storage is required.
• High Temperature Operation — Rated for −25°C to +105°C operation, with endurance specified for 2000 hours at 105°C for the 500 V variant.
• High Ripple Current Capability — 4.20 A low-frequency ripple current at 120 Hz and 5.88 A high-frequency ripple current at 100 kHz, enabling effective smoothing under varying ripple spectra.
• Leakage and Loss — Specified leakage current of 1740 µA and maximum tan δ of 0.2 at 20°C, 120 Hz, supporting predictable loss characteristics in design.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-resistance connections and simplified mechanical integration into power assemblies.
• Compact, Defined Package — Physical size φ51 × 100 mm (L: 10 cm × D: 5.1 cm) and cardboard packing for handling and assembly.
• Compliance — RoHS-compliant construction.

Typical Applications

• General high-voltage power supplies — Bulk smoothing and energy storage where a 500 V, high-temperature-capable capacitor is required.
• Industrial power conversion — DC-link and filter applications that benefit from screw-terminal mounting and high ripple-current capability.
• Energy buffering / ride-through — Short-term energy storage in systems operating up to +105°C with a 500 V bus.

Unique Advantages

• High-voltage rating (500 V): Enables use in higher-voltage DC systems without stacking multiple lower-voltage parts.
• Elevated operating temperature: Rated to +105°C with a specified 2000-hour life at that temperature for the 500 V class, supporting thermally demanding installations.
• Robust ripple handling: Dual-spec ripple current ratings (4.20 A at 120 Hz and 5.88 A at 100 kHz) address both low- and high-frequency ripple environments.
• Screw-terminal connectivity: Provides secure, low-impedance electrical connections and straightforward mounting for serviceable power systems.
• Predictable electrical characteristics: Specified leakage current (1740 µA) and tan δ (0.2 at 20°C, 120 Hz) simplify thermal and loss budgeting in designs.
• RoHS-compliant: Aligns with environmental and regulatory requirements for electronics assemblies.
