LNT1E473MSEB

The LNT1E473MSEB is a screw-terminal aluminum electrolytic capacitor offering 47,000 µF capacitance at a 25 V rating in a radial can package. It is designed for general-purpose power applications that require high bulk capacitance, robust ripple handling and secure screw-terminal connections.

With an operating temperature range down to –40 °C and up to 105 °C and a rated lifetime of 2,000 hours at 105 °C under rated ripple conditions, this capacitor supports demanding thermal and power environments common in industrial and general-purpose power systems.

Key Features

• Capacitance & Tolerance — 47,000 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C), providing substantial bulk energy storage for smoothing and decoupling.
• Rated Voltage — 25 V DC rated voltage suitable for low-voltage power rails and power-supply energy buffering.
• High-Temperature Endurance — Rated for operation from –40 °C to +105 °C with a specified lifetime of 2,000 hours at 105 °C under rated ripple conditions.
• Mounting & Package — Screw terminal radial can (φ51 × 80 mm) package for robust, low-impedance connections and easy field wiring.
• Ripple Current Capability — Handles 8.3 A at 120 Hz and 9.545 A at 100 kHz, enabling reliable performance under AC ripple and high-frequency loading.
• Polarized Design — Polar capacitor construction for DC bulk storage and filtering applications.
• RoHS Compliant — Meets RoHS requirements for lead-free manufacturing and regulatory compliance.

Typical Applications

• General-purpose power systems — Bulk smoothing and decoupling in power supplies and converters where high capacitance and ripple handling are required.
• Industrial equipment — Energy buffering and filtering in industrial power electronics that operate across a wide temperature range.
• Backup and hold-up circuits — Temporary energy storage for ride-through and hold-up functions, leveraging the large 47,000 µF capacitance.

Unique Advantages

• Large bulk capacitance: 47,000 µF provides significant energy storage per component, reducing the number of devices required for the same capacitance budget.
• Screw-terminal reliability: M5 screw terminals and a radial can package deliver secure, low-resistance connections for high-current applications.
• High ripple acceptance: Rated ripple currents at both 120 Hz and 100 kHz support performance under AC-loaded and high-frequency conditions.
• Wide temperature range: –40 °C to +105 °C operation enables deployment in thermally challenging environments.
• Designed for extended operation at elevated temperatures: Specified 2,000-hour lifetime at 105 °C under rated ripple current to support sustained high-temperature use.
• Regulatory compliance: RoHS-compliant construction supports regulatory requirements for lead-free assemblies.
