LNT2A473MSEB

The LNT2A473MSEB is an aluminum electrolytic capacitor in Nichicon’s LNT series designed as a screw‑terminal, radial can device. It provides 47,000 µF capacitance at a 100 V rating with polarized construction and is intended for general purpose applications that require high bulk capacitance and sustained ripple handling.

Its specification set—including a -40°C to +105°C operating range, high ripple current ratings, and RoHS compliance—positions the component for applications where reliable energy storage, smoothing and ripple endurance are required in a screw‑terminal package.

Key Features

• Capacitance and Voltage: 47,000 µF (47 mF) rated at 100 V, providing substantial bulk energy storage in a single component.
• High Ripple Current: Rated ripple current of 17 A at 120 Hz and 19.55 A at 100 kHz to support circuits with sustained AC ripple loads.
• Temperature Range and Endurance: Operates from -40°C to +105°C with a rated lifetime of 2000 hours at +105°C.
• Mounting and Package: Screw terminal, radial can construction for secure bolted connections and mechanical stability.
• Polarized Design: Polar capacitor for DC energy storage applications.
• Tolerance: Capacitance tolerance of ±20% at 120 Hz, 20°C.
• Dimensions: Physical size documented as L: 14 × D: 9 cm in the specification set.
• RoHS Compliance: Conforms to RoHS directive requirements as noted for the LNT series.

Typical Applications

• General‑purpose power circuits: Bulk energy storage and smoothing where high capacitance and a 100 V rating are required.
• High‑ripple environments: Circuits subject to sustained ripple currents can use this part to handle significant ripple at both power‑line and high frequencies (17 A at 120 Hz, 19.55 A at 100 kHz).
• Temperature‑challenging systems: Systems requiring components that operate from -40°C to +105°C and sustain rated lifetime at elevated temperature.

Unique Advantages

• Large single‑component capacitance: 47,000 µF reduces the need for parallel arrays and simplifies board layout for bulk storage.
• High voltage capability: 100 V rating supports higher‑voltage DC bus and energy storage requirements.
• Screw‑terminal connectivity: Provides secure, low‑resistance mechanical attachment suitable for robust power assemblies.
• Designed for ripple endurance: High ripple current ratings at both 120 Hz and 100 kHz improve reliability in ripple‑intensive designs.
• Wide operating temperature: -40°C to +105°C range and 2000 h life at 105°C for predictable performance in elevated temperature environments.
• Regulatory compliance: RoHS compliant to meet environmental directive requirements.
