LNC2H103MSEJBN

The LNC2H103MSEJBN is a screw-terminal aluminum electrolytic capacitor designed for high-power industrial applications. It is a smaller-sized, high ripple-current capacitor rated 10,000 µF (10 mF) at 500 V and specified for operation from –40 °C to +85 °C.

Optimized for inverter circuitry and high-frequency regenerative voltages, this Nichicon LNC series part delivers long load life under ripple conditions (5,000 hours at 85 °C) and is RoHS compliant.

Key Features

• High Capacitance and Voltage: 10,000 µF (10 mF) capacitance at a 500 V rated voltage, providing bulk energy storage for inverter and power-supply systems.
• High Ripple Current Capability: Rated ripple current of 38.3 A at 120 Hz and 53.62 A at 100 kHz, supporting heavy AC and high-frequency charge–discharge loading.
• Long Load Life: Endurance specified as 5,000 hours at 85 °C when DC bias plus rated ripple current is applied, with capacitance change within ±20% and leakage current within initial limits after test.
• Temperature Range: Operates from –40 °C to +85 °C to cover demanding industrial ambient conditions.
• Robust Electrical Safety Characteristics: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2,500 V for 1 minute without abnormality.
• Mechanical / Mounting: Screw terminal radial can package for secure, high-current terminations; smaller-sized format compared with LNX/LNK series variants.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is ≤ 3√(V) µA or 5 mA, whichever is smaller, enabling predictable standby and fault behavior.
• Charge–Discharge Endurance: Designed to tolerate high-speed charge–discharge cycles; specified endurance includes 50 million charge–discharge cycles with ΔV = rated voltage × 0.3 at 3 Hz (room temperature) while meeting post-test electrical limits.
• Polarized Electrolytic: Polarized design with ±20% capacitance tolerance (at 120 Hz, 20 °C).
• Standards Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters: Bulk energy storage and smoothing for inverter power stages where high voltage and sustained ripple handling are required.
• AC Servo Drives and Regenerative Systems: Handles high-frequency regenerative voltage and rapid charge–discharge cycles common in servomotor and motion-control systems.
• General Industrial Power Supplies: Filtering and energy buffering in power supplies for heavy-duty industrial equipment.

Unique Advantages

• High Ripple Tolerance: Measured ripple current ratings at both 120 Hz and 100 kHz enable use in low- and high-frequency power stages.
• Compact for Its Class: Marketed as smaller-sized compared with related LNX/LNK series parts, providing space savings in power-dense designs.
• Long-Term Reliability: 5,000-hour load-life specification at 85 °C under rated ripple current supports predictable long-term performance in industrial environments.
• Validated Endurance: Specified endurance for high-speed charge–discharge cycles (50 million cycles at defined test conditions) confirms suitability for regenerative and pulsed applications.
• Secure Screw-Terminal Mounting: Screw terminals and radial can package provide robust mechanical and electrical connections for high-current applications.
• RoHS Compliance: Meets RoHS requirements, simplifying use in regulated product lines and reducing materials risk.
