LNT1H474MSE

The LNT1H474MSE is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering very high bulk capacitance (470,000 µF) at a 50 V rating and an operating temperature up to 105°C. It is a radial can with screw terminals designed for general‑purpose power applications that require large energy storage and sustained ripple handling.

Engineered for sustained operation at elevated temperature, this part delivers rated ripple current performance and a specified load life of 2000 hours at 105°C when operated under rated bias and ripple conditions.

Key Features

• High Capacitance & Voltage — 470,000 µF nominal capacitance rated at 50 V, providing substantial bulk energy storage for power systems.
• High Temperature Endurance — Rated for operation from −40°C to +105°C with a specified lifetime of 2000 hours at 105°C under rated ripple/bias conditions.
• Screw Terminal Mounting — Radial can package with screw terminals enables secure, high‑current connections for power modules and bus applications.
• Robust Ripple Current Capability — Rated ripple current: 26.1 A at 120 Hz and 30.02 A at 100 kHz, supporting demanding AC ripple and switching environments.
• Polarized, ±20% Tolerance — Polarized design with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Physical Size & Mounting Details — Large can size specified as φ100 × 250L; SizeDimension listed as L: 25 x D: 10 cm and HeightSeatedMax of 9.843 inch; 3‑leg and 2‑leg bracket mounting options are available for larger diameters per series documentation.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current meets the datasheet limit: not more than 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20°C).
• RoHS Compliant — Manufactured to comply with RoHS directive requirements.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing where very large capacitance and high ripple current capacity are required.
• Industrial power electronics — DC link and power conditioning roles in equipment that must sustain elevated operating temperatures.
• High‑energy storage modules — Systems that benefit from dense capacitance in a screw‑terminal, serviceable package for robust connections.

Unique Advantages

• Substantial bulk capacitance: 470,000 µF provides large energy reserve to support power-holdup and smoothing functions without adding multiple smaller capacitors.
• High ripple handling: Rated ripple currents at both low and high frequencies help reduce heating and extend operational stability under AC and switching loads.
• Designed for elevated temperatures: 105°C operating rating and a defined 2000‑hour lifetime at 105°C give predictable aging and replacement scheduling for high‑temperature installations.
• Secure screw‑terminal connections: Screw terminals and heavy‑duty can construction simplify integration into power racks and bus systems while enabling reliable high‑current terminations.
• Clear electrical limits: Datasheet leakage current, tolerance, and endurance specifications allow straightforward design margins and qualification planning.
• Regulatory compliance: RoHS compliance supports use in regions and products where restricted substance requirements apply.
