LNT1A334MSEB

The LNT1A334MSEB is a large-can, screw terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It delivers high bulk capacitance in a robust radial can package with screw terminals for secure, low-impedance connections.

Designed for general-purpose power applications, this unit pairs 330,000 µF (330 mF) of capacitance with a 10 V rating, high ripple-current capability, and a wide operating temperature range to support demanding power-smoothing and energy-storage tasks.

Key Features

• High Capacitance — 330,000 µF (330 mF) nominal capacitance with ±20% tolerance for substantial bulk energy storage and smoothing.
• Rated Voltage — 10 V DC rating suitable for low-voltage power rails and storage applications.
• High Ripple Current — 15.8 A at 120 Hz (low frequency) and 18.17 A at 100 kHz (high frequency), enabling effective handling of AC ripple and switching currents.
• Loss Factor (tan δ) — tan δ = 2 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for thermal and ripple-current planning.
• Robust Environmental Range — Operating temperature −40°C to +105°C with a rated life of 2,000 hours at +105°C under specified ripple/voltage conditions.
• Mounting & Package — Screw terminal radial can (φ76.2 × 120 mm) for secure mechanical and electrical connections in high-current layouts.
• Leakage Current — Specified leakage current up to 5,000 µA for planning standby and bias leakage budgets.
• Compliance & Packaging — RoHS compliant; supplied in cardboard packing and currently in mass production.

Typical Applications

• General Purpose Power Systems — Bulk energy storage and smoothing of low-voltage power rails where large capacitance and high ripple capability are required.
• Switching Power Supplies — Filtering and decoupling in supplies that present significant ripple currents at both low and high frequencies.
• Industrial Electronics — Energy buffering in industrial control and power electronics that operate within −40°C to +105°C and require screw-terminal mounting.

Unique Advantages

• Substantial Bulk Energy Capacity: 330,000 µF provides large charge reservoirs to reduce voltage sag and improve DC bus stability.
• Designed for High Ripple: Dual-specified ripple currents (15.8 A at 120 Hz, 18.17 A at 100 kHz) allow designers to manage both line-frequency and high-frequency ripple effectively.
• Durable Thermal Performance: Rated for −40°C to +105°C with a 2,000-hour endurance at 105°C, enabling reliable operation under elevated temperature stress.
• Secure Screw-Terminal Connections: Radial, screw-terminal can package simplifies high-current wiring and mechanical mounting in power assemblies.
• Specification Transparency: Clear leakage current and tan δ specifications support thermal, leakage, and lifetime budgeting during design.
• RoHS Compliant & Production-Ready: Meets RoHS requirements and is in mass production for predictable supply and procurement.
