LNT2V123MSEJ

The LNT2V123MSEJ is a screw-terminal, large-can aluminum electrolytic capacitor designed for general-purpose applications that require high capacitance and high-voltage handling. It provides 12,000 µF at a rated voltage of 350 V with robust ripple-current capability and a 105°C endurance rating.

Its combination of high capacitance, elevated ripple current ratings and a long-life endurance at elevated temperature makes it suitable for designs where bulk energy storage and reliable high-voltage filtering are required.

Key Features

• High capacitance and voltage: 12,000 µF nominal capacitance with a 350 V rated voltage for substantial energy storage in a single component.
• Screw-terminal package: Radial can with screw terminals provides secure, low-inductance connections for high-current power systems (φ90 × 190L).
• High ripple current capability: Low-frequency ripple current 36 A (120 Hz) and high-frequency ripple current 50.4 A (100 kHz) to support demanding AC ripple conditions.
• Endurance at elevated temperature: Rated life of 5,000 hours at +105°C with application of rated ripple current, supporting long-term operation in hot environments.
• Leakage and dissipation: Specified leakage current 5,000 µA and tan δ of 0.2 (measured at 20°C, 120 Hz), enabling predictable loss and leakage behavior.
• Operating temperature range: –25°C to +105°C to accommodate a wide range of ambient conditions.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in designs that require 12,000 µF at 350 V and high ripple-current capability.
• High-voltage filtering: Filtering and decoupling in high-voltage circuits where elevated ripple currents are present and reliable screw-terminal connections are preferred.
• Industrial power electronics: Use in industrial modules that operate at elevated temperatures and demand long endurance at +105°C.

Unique Advantages

• Large single-component capacitance: 12,000 µF at 350 V reduces board area and part count compared with multiple smaller capacitors.
• High ripple-handling capacity: 36 A (120 Hz) and 50.4 A (100 kHz) ratings directly address applications with significant AC ripple currents.
• Durable, high-temperature life: 5,000-hour endurance at 105°C gives predictable lifetime performance in elevated-temperature environments.
• Secure, serviceable connections: Screw-terminal construction facilitates reliable mechanical and electrical connections for high-current assemblies.
• Defined electrical characteristics: Specified tan δ, leakage current, and tolerance (±20%) support predictable design margins and system behavior.
• Regulatory compliance: RoHS compliance supports use in designs requiring restricted-substance conformity.
