LNT2H682MSEJ

The LNT2H682MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, featuring 6.8 mF (6800 µF) capacitance at a 500 V rating. Designed as a radial can with screw terminals, it delivers high-voltage energy storage with robust mechanical connection for general-purpose applications.

Key value propositions include high ripple-current capability, a wide operating temperature window up to 105°C, and RoHS compliance—attributes that support demanding, long-duration high-voltage applications within its specified endurance limits.

Key Features

• High Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance rated at 500 V for substantial energy storage in a single component.
• Screw Terminal Package: Radial, can-style package with screw terminals for secure, low-impedance connections and straightforward mounting.
• High Temperature Rating: Rated for operation up to 105°C; category temperature range for 160–500 V is −25°C to +105°C.
• High Ripple Current Handling: Rated ripple current of 20.7 A at 120 Hz and 28.98 A at 100 kHz to support continuous AC current stress at rated conditions.
• Endurance / Load Life: Specified lifetime of 2000 hours at 105°C under rated conditions (per LNT series endurance for 160–500 V parts).
• Polarized Electrolytic Design: Polar capacitor with ±20% capacitance tolerance at 120 Hz, 20°C.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Footprint: Radial can with screw terminals; size dimension listed as L: 17 × D: 9 cm and a maximum seated height of 6.693 inches.

Typical Applications

• General Purpose: Suitable for general-purpose electrical and electronic systems where a high-voltage, high-capacitance screw-terminal capacitor is required.
• General Purpose: Used in equipment designs that require robust terminal connections and high ripple-current capability at elevated temperatures.
• General Purpose: Applicable where long-duration operation at 105°C and rated ripple current are part of the design requirements.

Unique Advantages

• High-voltage single-component solution: 500 V rating with 6.8 mF capacitance reduces the need for multiple smaller capacitors in high-voltage designs.
• Robust electrical connections: Screw-terminal construction enables secure, low-resistance terminations for high-current and high-vibration environments.
• Designed for sustained stress: Rated ripple currents at both low and high frequencies and a 2000-hour endurance at 105°C support continuous operation under rated load.
• Wide operating temperature window: −25°C to +105°C for 160–500 V parts provides thermal headroom for elevated-temperature installations.
• Regulatory compliance: RoHS compliance supports environmentally conscious designs and supply-chain requirements.
