LNT1V473MSEN

The LNT1V473MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, designed as a 105°C standard, high-capacitance, polarized solution in a radial can package. It delivers 47,000 µF at 35 V with engineered electrical and mechanical robustness for general-purpose power applications.

Engineered for systems that require large bulk capacitance, high ripple handling and extended elevated-temperature endurance, this part is suited for designers specifying robust power filtering and energy storage where a screw-terminal connection and RoHS compliance are required.

Key Features

• Capacitance & Voltage: 47,000 µF rated at 35 V (±20% tolerance), providing substantial bulk energy storage for smoothing and decoupling functions.
• Screw Terminal Mounting: Radial can with screw terminals (φ51 × 100L) for secure, low-impedance connections; nominal bolt for φ51 terminal configuration is M5 as specified in the series drawings.
• High Ripple Capacity: Rated ripple current of 8.4 A at 120 Hz and 9.66 A at 100 kHz, supporting continuous AC ripple loading in power subsystems.
• Temperature & Endurance: Operates from −40°C to +105°C with a rated load life of 2000 hours at 105°C under rated ripple conditions (per series endurance definition for 10–250 V range).
• Loss Characteristic: Tangent of loss angle (tan δ) specified at 0.4, enabling predictable dissipation behavior for thermal and performance planning.
• Polarized, RoHS Compliant: Standard polarized aluminum electrolytic construction with RoHS compliance for environmental compatibility.

Typical Applications

• Power-supply bulk smoothing: Large capacitance and high ripple current make this capacitor suitable for bulk energy storage and smoothing of DC bus voltages where 35 V rating is appropriate.
• Power conversion and filtering: Use in converters and intermediate DC links that require substantial capacitance and elevated-temperature endurance up to 105°C.
• Industrial electronics: General-purpose power systems and control equipment requiring screw-terminal mounting for robust, low-resistance connections and maintenance-friendly installation.

Unique Advantages

• Very high bulk capacitance: 47,000 µF provides significant charge storage to stabilize DC rails and reduce voltage ripple without paralleling multiple smaller capacitors.
• Screw-terminal reliability: Bolt-mounted terminals (M5 for φ51 size) offer mechanically secure connections and ease of installation and service.
• Designed for elevated temperatures: Rated for operation to +105°C with a specified 2000-hour life at that temperature under rated ripple, enabling use in thermally demanding enclosures.
• Predictable ripple handling: Explicit ripple current ratings at 120 Hz and 100 kHz allow designers to size and thermal-manage the capacitor for intended operating profiles.
• RoHS compliant construction: Conforms to applicable RoHS directives for simplified environmental compliance in product builds.
