LNC2H103MSEJ

The LNC2H103MSEJ is a screw‑terminal aluminum electrolytic capacitor designed for industrial power electronics where high energy storage and high ripple handling are required. It is a polarized, radial can style capacitor optimized for inverter circuitry and regenerative power applications.

With a rated capacitance of 10,000 μF at 500 V and an operating temperature range of −40 °C to +85 °C, this part delivers high ripple current capability in a smaller-sized package and is compliant with the RoHS directive.

Key Features

• High Voltage Energy Storage: 10,000 μF capacitance rated at 500 V for bulk energy smoothing and DC link applications.
• High Ripple Current Performance: Rated ripple current of 38.3 A at 120 Hz and 53.62 A at 100 kHz supports high-frequency charge/discharge and switching loads.
• Temperature and Lifetime: Operating range −40 °C to +85 °C with a load life specified as 5,000 hours at 85 °C under applied ripple current.
• Robust Endurance: Meets endurance for 50 million charge/discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature without exceeding specified electrical characteristic changes.
• Mounting and Package: Screw terminal, radial can with screw terminals for secure, high-current connections in power modules and assemblies.
• Leakage and Insulation: Leakage current after 5 minutes is specified as not more than 3√(V) μA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliant: Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk DC link and smoothing in inverter power supplies where sustained ripple handling and high voltage rating are required.
• Motor Drives and AC Servomotors: Support for regenerative voltages and high-speed charge/discharge behavior in motor control electronics.
• Regenerative Inverters: Energy buffering for systems that experience frequent high-frequency switching and bidirectional power flow.
• High-Frequency Switching Circuits: Applications demanding high ripple current at both low and high frequencies, benefiting from the capacitor’s frequency-specific ripple ratings.

Unique Advantages

• High Voltage and High Capacitance in One Part: 10,000 μF at 500 V enables substantial energy storage for DC link and smoothing without combining multiple lower‑voltage parts.
• Engineered for High Ripple Loads: Specified ripple current values at 120 Hz and 100 kHz reduce thermal stress and support reliable operation under switching loads.
• Smaller-Sized Design: Described as smaller-sized while maintaining high ripple capability, allowing more compact power assemblies.
• Proven Endurance: Load life of 5,000 hours at 85 °C and validated charge/discharge endurance provide predictable aging and performance over time.
• Secure Screw-Terminal Mounting: Screw terminals provide robust electrical and mechanical connections for high-current installations.
• Measured Leakage and Insulation Specs: Defined leakage current limits and insulation resistance ensure safe, verifiable performance after installation and during operation.
