LNT1A334MSE

The LNT1A334MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering very high bulk capacitance in a radial can with screw terminals. It is a polarized, general-purpose capacitor engineered for applications that require large energy storage, high ripple-current handling, and robust operation at elevated temperatures.

Key attributes include 330000 µF capacitance at 10 V, rated operation from −40°C to +105°C, and a 2000 hour endurance at 105°C under rated ripple current. The part is RoHS compliant and available in mass production with cardboard packing.

Key Features

• High Capacitance, Low Voltage — 330000 µF (330 mF) capacitance at a rated voltage of 10 V provides substantial bulk energy storage in a single component.
• Screw-Terminal Mounting — Radial can with screw terminals and M5 bolt provision (for φ76.2 case) enables secure, low-resistance electrical connection and simple mechanical attachment.
• High Ripple Current Capability — Low-frequency ripple current 15.8 A (120 Hz) and high-frequency ripple current 18.17 A (100 kHz) for applications with significant AC content on the DC bus.
• Thermal and Endurance Performance — Rated for operation from −40°C to +105°C with 2000 hours life at 105°C under rated ripple current (endurance per product specification).
• Electrical Characteristics — Capacitance tolerance −20% to +20%; tangent of loss angle (tan δ) = 2 (measured at 20°C, 120 Hz); leakage current specified at 5000 µA.
• Physical and Packaging Details — Size φ76.2 × 120 L (7.62 cm diameter × 12 cm length); packaged in cardboard; status: mass production.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose — Designed for general-purpose circuitry where large capacitance and a screw-terminal connection are required.
• High Ripple Current Systems — Suited to power electronics that impose significant ripple on DC rails, leveraging its specified low- and high-frequency ripple current ratings.
• Elevated Temperature Environments — Applicable where operation up to +105°C is required, supported by specified endurance at that temperature.

Unique Advantages

• Massive Bulk Storage in One Device: 330000 µF capacity reduces the need for multiple smaller capacitors, simplifying BOM and PCB layout.
• Screw-Terminal Reliability: Robust screw-terminal connections provide secure electrical and mechanical attachment for high-current applications.
• High Ripple Handling: Rated ripple currents of 15.8 A (120 Hz) and 18.17 A (100 kHz) support designs with substantial AC components on DC lines.
• Wide Operating Temperature and Specified Endurance: −40°C to +105°C operation and 2000 hours endurance at 105°C offer predictable performance in hotter environments.
• Production-Ready Supply: Product is listed as mass production and shipped in cardboard packing for standard handling and storage.
• Regulatory Compliance: RoHS compliance facilitates use in environments where hazardous-substance restrictions apply.
