LNT1A473MSE

The LNT1A473MSE is an aluminum electrolytic capacitor from Nichicon’s LNT series, configured with screw terminals for robust, low-impedance connections. This high-capacitance, low-voltage device is designed for general-purpose applications that require bulk energy storage and high ripple-current handling in demanding temperature environments.

Key characteristics include a nominal capacitance of 47 mF (47,000 µF) at 10 V, a wide operating temperature range of −40°C to +105°C, and an endurance rating of 2000 hours at 105°C when subjected to rated ripple current.

Key Features

• High Capacitance: 47 mF (47,000 µF) nominal capacitance with a tolerance of −20% to +20% at 120 Hz, 20°C, providing substantial bulk energy storage for power smoothing and reservoir functions.
• Rated Voltage & Dielectric Loss: Rated at 10 V with a tangent of loss angle (tan δ) of 0.65 measured at 20°C, 120 Hz, enabling designers to predict ESR-related losses.
• High Ripple Current Capability: Low-frequency ripple current of 6.2 A (120 Hz) and high-frequency ripple current of 7.13 A (100 kHz), supporting applications with significant AC ripple stress.
• Leakage Current: Specified leakage current of 2050 µA after 5 minutes at rated voltage (20°C) for predictable standby characteristics.
• Thermal and Endurance Performance: Operating range −40°C to +105°C with rated lifetime of 2000 hours at 105°C under rated ripple current for long-term stability in elevated-temperature environments.
• Screw Terminal Package: Radial can with screw terminals and φ35 × 100 mm size (approximately 3.5 cm × 10 cm) for secure mechanical and electrical connections in power assemblies.
• RoHS Compliant and Production Ready: RoHS-compliant construction, supplied in cardboard packing, and listed as mass production.

Typical Applications

• General-Purpose Power Supplies: Bulk energy storage and smoothing where high capacitance and high ripple-current capability are required to stabilize DC rails.
• Industrial Power Electronics: Use in systems that demand robust screw-terminal connections and high ripple handling over extended temperature ranges.
• Energy Reservoirs and Filtering: Local energy buffering and decoupling in systems that need substantial charge storage and predictable leakage behavior.

Unique Advantages

• Large Stored Energy per Volume: 47 mF capacitance provides significant bulk charge capacity for smoothing and transient support, reducing the need for multiple smaller capacitors.
• Designed for High Ripple Stress: Specified ripple currents at both low and high frequencies (6.2 A at 120 Hz, 7.13 A at 100 kHz) enable reliable operation in AC-stressed circuits.
• Robust Mechanical Termination: Screw terminal package simplifies high-current wiring and mechanical mounting for power assemblies.
• Elevated-Temperature Endurance: Rated 2000 hours at 105°C under rated ripple conditions, supporting prolonged operation in higher-temperature environments.
• Predictable Leakage and Loss Characteristics: Leakage current (2050 µA) and tan δ (0.65) specifications allow accurate thermal and standby loss budgeting in system design.
