LNC2G392MSEHBB

The LNC2G392MSEHBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power applications. It delivers 3.9 mF capacitance at a 400 V rating in a compact package optimized for high ripple current and high-speed charge–discharge environments.

Targeted for inverter circuitry and regenerative power stages, this part offers a combination of high ripple capability, a −40 °C to +85 °C operating range, and a rated load life of 5000 hours at 85 °C, making it suitable for demanding industrial power-supply and motor-drive designs.

Key Features

• Core Technology  Aluminum electrolytic, polarized capacitor with 3.9 mF capacitance and 400 V rated voltage (tolerance ±20%).
• High Ripple Current  Designed for high ripple environments: 17.1 A at 120 Hz and 23.94 A at 100 kHz, supporting high-frequency regenerative loads.
• Reliability & Lifetime  Load life specified as 5000 hours with rated ripple current applied at 85 °C; endurance tests include charge–discharge cycling (50 million cycles at room temperature, ΔV = rated × 0.3, 3 Hz).
• Temperature Range  Operates from −40 °C to +85 °C with specified impedance stability (Z(−40 °C)/Z(+20 °C) ≤ 8).
• Package & Mounting  Radial screw-terminal can (screw terminal type) sized L: 8.0 cm × D: 7.62 cm with a seated height specification; suitable for screw-mount installations.
• Electrical Safety Characteristics  Leakage current specification: after 5 minutes at rated voltage, leakage ≤ 3√V (µA) or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V, 1 minute between terminal and bracket.
• Endurance Characteristics  After endurance testing, requirements include capacitance change within ±20%, tan δ ≤ 200% of initial specified value, and leakage current ≤ initial specified value.
• RoHS Compliance  Designed and produced in compliance with the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Industrial Power Supplies (Inverter circuitry)  Used for bulk energy storage and ripple filtering in industrial inverter power supplies where high ripple current handling is required.
• AC Servomotor Regenerative Circuits  Handles high-frequency regenerative voltage and rapid charge–discharge cycles typical in servo drive systems.
• General Inverters and Motor Drives  Provides robust smoothing and transient energy buffering for inverters and motor-drive power stages operating up to 85 °C.

Unique Advantages

• Smaller footprint with higher ripple capability: Combines compact radial screw-terminal packaging with ripple performance specified at both 120 Hz and 100 kHz to save space without sacrificing power handling.
• Designed for high-frequency duty: Rated ripple current at 100 kHz and explicit charge–discharge endurance testing make it suitable for high-speed regenerative and switching environments.
• Long operational life under load: 5000-hour load-life rating at 85 °C under rated ripple current provides predictable aging and replacement planning for industrial systems.
• Robust electrical safety margins: Defined leakage, insulation resistance, and voltage-proof specifications support reliable integration into high-voltage assemblies.
• Wide temperature tolerance: −40 °C to +85 °C operating range supports deployment across varied industrial ambient conditions.
