LNC2H472MSEJBB

The LNC2H472MSEJBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, rated 4700 µF at 500 V. It is a radial can with screw terminals designed for industrial power applications where high ripple-current capability, long load life, and robust charge–discharge performance are required.

Typical use cases include industrial inverter power supplies and regenerative drives where high-frequency ripple and rapid charge/discharge cycles are present. The device combines high ripple-current handling with a compact form factor within the LNC family.

Key Features

• Electrical Performance — 4700 µF capacitance at 500 V with ±20% tolerance, polarized design suitable for high-voltage DC link applications.
• High Ripple Current — Rated ripple current: 23.6 A at 120 Hz and 33.04 A at 100 kHz, supporting heavy AC ripple and high-frequency operation.
• Reliability & Endurance — Load life of 5000 hours at 85°C under rated ripple current; endurance after charge–discharge testing specified (50 million cycles at ΔV = 0.3 × rated, 3 Hz).
• Thermal Range — Operating temperature range from −40°C to +85°C, enabling use across typical industrial temperature environments.
• Leakage Current — After 5 minutes at rated voltage, leakage current is limited to 3√V (µA) or 5 mA, whichever is smaller (at 20°C), per datasheet specification.
• Mechanical & Mounting — Radial can with screw terminals for secure, low-inductance connections in power assemblies.
• Insulation & Voltage Proof — Insulation resistance >100 MΩ at DC 500 V (terminal to bracket) and withstands AC 2500 V for 1 minute without abnormality.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact LNC Series Design — Described as smaller-sized with higher ripple current capability compared to other series variants within the same family.

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitor for inverter power stages where sustained ripple current and voltage stability are required.
• Regenerative Drives and AC Servomotors — Handles high-frequency regenerative voltage and frequent charge/discharge cycles in motor control systems.
• General Inverters — Energy storage and ripple suppression in inverters for industrial equipment and power conversion modules.

Unique Advantages

• High ripple-current capacity: Specified 23.6 A at 120 Hz and 33.04 A at 100 kHz, enabling reliable operation under heavy AC ripple and high-frequency switching conditions.
• Long elevated-temperature life: 5000 hours at 85°C under rated ripple conditions for predictable long-term performance in hot enclosures.
• Robust charge–discharge endurance: Verified for 50 million charge–discharge cycles (ΔV = 0.3 × rated, 3 Hz), supporting high-speed cycling in regenerative applications.
• Secure screw-terminal mounting: Radial can with screw terminals provides strong mechanical retention and low-inductance connections for power assemblies.
• Measured insulation and voltage proof: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V, 1 minute voltage proof between terminal and bracket.
• RoHS compliant manufacturing: Conforms to applicable RoHS directives, suitable for environments requiring restricted substances compliance.
