LNC2V103MSEHBN

The LNC2V103MSEHBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, designed for industrial power systems requiring high ripple-current capability in a compact package. It is a polarized, radial can capacitor rated at 350 V with 10 mF capacitance and RoHS compliance.

Targeted at inverter and regenerative power applications, this capacitor is optimized for high-frequency charge–discharge and regenerative voltages such as those found in AC servomotor and general inverter circuits. It delivers long service life under ripple loading with a specified endurance of 5000 hours at 85°C.

Key Features

• Rated electricals — 10 mF capacitance at 350 V DC; capacitance tolerance ±20% (at 120 Hz, 20°C).
• Screw-terminal radial can — Screw terminal mounting for secure electrical connections and straightforward installation in power assemblies.
• High ripple-current handling — Rated ripple current: 25.2 A at 120 Hz and 35.28 A at 100 kHz, supporting demanding AC and high-frequency regenerative loads.
• Operating temperature and life — Rated for –40°C to +85°C with a load-life specification of 5000 hours at 85°C under rated ripple current.
• Durability under fast charge–discharge — Endurance for charge–discharge behavior: rated for 50 million cycles at ΔV = 0.3 × rated voltage, 3 Hz, at room temperature.
• Electrical reliability — Leakage current after 5 minutes at rated voltage is ≤ 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 for 1 minute between terminal and bracket.
• Compact dimensions — Package size L: 13.5 × D: 7.62 cm provides a smaller footprint compared with other LNC family references while maintaining high ripple capability.
• Standards compliance — Compliant with the RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverters — Energy storage and smoothing for inverter DC link circuits where high ripple current and reliable endurance are required.
• AC servomotor regenerative circuits — Handling high-frequency regenerative voltages and rapid charge–discharge cycles in servo drive systems.
• High-frequency power supplies — Filtering and energy buffering in high-frequency switching and regenerative power topologies.

Unique Advantages

• High ripple-current capability: Supports 25.2 A at 120 Hz and 35.28 A at 100 kHz, enabling robust performance in demanding inverter and regenerative applications.
• Long rated life under load: 5000 hours at 85°C under rated ripple current provides predictable long-term behavior in industrial environments.
• Designed for fast charge–discharge: Qualified for 50 million charge–discharge cycles (ΔV = 0.3 × Vr, 3 Hz), making it suitable for repetitive regenerative events.
• Secure screw-terminal mounting: Screw terminals simplify installation and ensure durable electrical connections in power assemblies.
• Proven electrical safeguards: Specified leakage, insulation resistance, and high-voltage proof limits support reliable integration into power systems.
• RoHS compliance: Meets RoHS directive requirements for environmentally conscious designs.
