LNC2V392MSEHBB

The LNC2V392MSEHBB is a screw‑terminal aluminum electrolytic capacitor designed for industrial power electronics. It combines a compact can-style radial package with high ripple-current handling and a polarized 3.9 mF capacitance at a 350 V rating.

Engineered for inverter circuitry and high-frequency regenerative systems, this part offers a 5000‑hour load life at 85°C under ripple current, a wide operating range from −40°C to +85°C, and robust charge–discharge endurance for demanding power-supply and motor-control environments.

Key Features

• Electrical Rating — Rated capacitance 3.9 mF with a nominal voltage of 350 V and capacitance tolerance ±20%.
• Screw‑Terminal Mounting — Radial can package with screw terminals for secure, low‑impedance connections in power assemblies.
• High Ripple Current Capability — Handles 14.3 A at 120 Hz and 20.02 A at 100 kHz, supporting both low‑frequency smoothing and high‑frequency regenerative currents.
• Operating Range — Specified for −40°C to +85°C to accommodate industrial ambient conditions.
• Long Load Life — Designed for 5000 hours of ripple‑current application at 85°C; endurance requirements include capacitance change within ±20%, tan δ ≤200% of initial, and leakage current not exceeding initial specified value after test.
• Leakage Current Specification — After 5 minutes at rated voltage and 20°C, leakage current is limited to not more than 3√V (μA) or 5 mA, whichever is smaller, supporting predictable standby and fault behavior.
• Compact Mechanical Footprint — Can‑style radial package with physical dimensions L: 7 cm × D: 7.62 cm and a seated height max of 2.756 inch for space‑constrained power modules.
• RoHS Compliant — Meets RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Bulk energy storage and smoothing for inverter front‑ends, where high ripple capability and long life at 85°C are required.
• AC Servomotor Regeneration — Support for high‑frequency regenerative voltages and frequent charge–discharge cycles in servo and motor‑control systems.
• High‑Frequency Power Conditioning — Filtering and energy buffering in systems that combine low‑ and high‑frequency ripple components (120 Hz and up to 100 kHz).
• General Purpose Industrial Power — Use in power racks and modules requiring a polarized, screw‑terminal aluminum capacitor with robust endurance and predictable leakage behavior.

Unique Advantages

• High Ripple Handling: Explicit ripple ratings at both 120 Hz (14.3 A) and 100 kHz (20.02 A) let designers size bulk and decoupling networks with measured current limits.
• Validated Endurance: 5000‑hour load‑life specification at 85°C with defined post‑test limits (capacitance ±20%, tan δ ≤200% of initial, leakage ≤ initial) reduces uncertainty for life‑cycle planning.
• Secure Mechanical Termination: Screw terminals provide low‑resistance, reliable connections suitable for high‑current industrial wiring and serviceability.
• Predictable Leakage Behavior: A clear leakage‑current limit formula (3√V μA or 5 mA) simplifies worst‑case power and standby calculations.
• Compact Form Factor: Radial can package with modest footprint (7.0 × 7.62 cm) helps integrate high‑capacitance storage into constrained power assemblies.
