LNC2H682MSEJBB

The LNC2H682MSEJBB is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNC series, offering 6.8 mF capacitance at 500 V in a compact, high-ripple format. It is designed for general-purpose industrial power electronics, especially inverter and regenerative circuits where high-voltage bulk capacitance and robust ripple handling are required.

This unit combines a high nominal capacitance, a rated voltage of 500 V, and an operating temperature range of –40 °C to +85 °C, with a rated load life of 5000 hours at 85 °C to support sustained operation under heavy ripple and charge–discharge loading.

Key Features

• High Capacitance and Voltage — 6.8 mF nominal capacitance rated at 500 V for bulk energy storage and DC-link applications.
• Screw-Terminal Mounting — Robust screw terminal and radial can package for secure connections in power assemblies and easy installation in industrial racks.
• High Ripple Current Capability — Rated ripple current: 30 A at 120 Hz and 42 A at 100 kHz, supporting high-frequency and heavy-load ripple environments.
• Thermal and Lifetime Performance — Operating range –40 °C to +85 °C with a load life of 5000 hours at 85 °C under rated ripple current conditions.
• Durable, Compact Package — φ90×145L can size (L: 14.5 cm × D: 9 cm) offers a smaller footprint for its class while maintaining high performance.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Leakage and Reliability — Leakage current specification after 5 minutes: not more than 3√(V) µA or 5 mA (whichever is smaller), with endurance and shelf-life characteristics defined in the datasheet.

Typical Applications

• Industrial Inverters and Drives — Bulk DC-link and regenerative circuits for AC servomotor and general inverter systems where high-voltage energy buffering and high-frequency charge–discharge are required.
• Power Supplies — High-voltage smoothing and energy storage in industrial power supplies, supplying stable DC under heavy ripple conditions.
• Regenerative Energy Circuits — Supports high-frequency regenerative voltages in systems that require frequent charge–discharge cycles.
• Test and Laboratory Equipment — Suitable for applications that impose high ripple currents and repeated charge–discharge loads at elevated voltages.

Unique Advantages

• High-Voltage Bulk Capacity: 6.8 mF at 500 V provides substantial energy storage in a single component for DC-link and smoothing duties.
• Designed for Heavy Ripple: Specified ripple current up to 42 A at 100 kHz and 30 A at 120 Hz enables use in high-frequency and low-frequency ripple environments alike.
• Long Operational Life at Elevated Temperature: 5000 hours rated life at 85 °C under rated ripple load supports sustained industrial operation.
• Robust Mechanical Termination: Screw-terminal radial can package ensures secure electrical and mechanical connections for demanding installations.
• Compact Form Factor for Performance: φ90×145L package (L: 14.5 cm × D: 9 cm) offers a balance of high capacitance and manageable footprint.
• Standards-Compliant Materials: RoHS compliance aligns the component with common regulatory requirements for electronic assemblies.
