LNY2G103MSEH

The LNY2G103MSEH is a screw‑terminal aluminum electrolytic capacitor offering 10,000 µF capacitance at a 400 V rating in a high‑capacitance LNY series package. Designed for general‑purpose power applications, it combines high capacitance, high rated voltage and screw‑terminal mounting to serve bulky smoothing and energy‑storage roles in equipment where secure mechanical and electrical connections are required.

Key product attributes include a −40°C to +85°C operating range, a 2000‑hour load life at 85°C under rated ripple, and RoHS compliance—making it suitable for long‑life industrial and commercial power designs that require reliable high‑voltage bulk capacitance.

Key Features

• High Capacitance and Voltage — 10,000 µF rated capacitance at 400 V to provide significant bulk energy storage for 400 V systems.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low‑impedance electrical connection and robust mechanical mounting in high‑current power assemblies.
• High Ripple Current Capability — 22.4 A at 120 Hz and 31.36 A at 10 kHz ripple current ratings to support heavy AC ripple conditions within the specified temperature limits.
• Endurance — 2000 hours rated life at 85°C with rated DC plus ripple applied, supporting extended service in continuous‑load environments.
• Leakage and Loss Characteristics — Specified leakage current of 5000 µA and a tangent of loss angle (tan δ) of 0.25 for predictable loss behavior under test conditions.
• Wide Operating Temperature — −40°C to +85°C category temperature range and impedance stability (Z(−40°C)/Z(+20°C) up to 12) for operation across broad environmental conditions.
• Safety and Insulation — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket and voltage proof of AC 2500 V for 1 minute between terminal and bracket, per series specifications.
• Form Factor — φ76.2 × 170 mm can style optimized for equipment downsizing while delivering high capacitance per package.

Typical Applications

• General‑Purpose Power Supplies — Bulk smoothing and energy storage for 400 V power rails in industrial and commercial power systems where secure screw‑terminal connections are preferred.
• Industrial Equipment — Provides high‑voltage bulk capacitance for machinery and power conversion equipment that require robust mounting and high ripple handling.
• Energy Storage and Filtering — Suitable for DC link or bulk filter sections in high‑voltage assemblies that demand long life at elevated temperatures.

Unique Advantages

• Substantial Bulk Capacitance at 400 V — Delivers 10,000 µF at a high voltage rating to reduce the number of capacitors required for equivalent energy storage.
