LNR2D472MSE

The LNR2D472MSE is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require high capacitance at elevated voltage. It pairs a 200 V rated voltage with 4700 µF (4.7 mF) capacitance in a radial can with screw terminals, providing a robust, serviceable connection for DC-link, energy storage and power smoothing roles.

Engineered for durability, this component is specified for operation from −25°C to 85°C and a rated lifetime of 5000 hours at 85°C. Key performance attributes include a maximum tangent of loss angle (tan δ) of 0.15 and measurable ripple current ratings across low and high frequency bands.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C, providing bulk energy storage for power applications.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance connections and straightforward field installation or maintenance.
• Thermal & Lifetime Performance — Rated operating temperature −25°C to 85°C and endurance of 5000 hours at 85°C when subjected to DC bias plus rated ripple current; after endurance test, capacitance change remains within ±15% and leakage current stays at or below the initial specified value.
• Loss and Leakage Characteristics — Specified tan δ of 0.15 (max) and leakage current limited to not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20°C, enabling predictable dissipation and self-discharge behavior.
• Ripple Current Ratings — 6.3 A at 120 Hz and 7.56 A at 100 kHz, supporting a range of switching and filtering conditions across low- and high-frequency power circuits.
• Mechanical & Packaging — Body dimensions approximately φ51 × 100 mm (L: 10 × D: 5.1 cm) with standard 3‑leg mounting bracket for φ51 sizes; supplied in cardboard packing for mass production handling.
• Regulatory — RoHS compliant, supporting environmental and materials requirements for commercial and industrial products.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing in medium-voltage DC power supplies where 200 V rating and high capacitance are required.
• Industrial Power Electronics — DC-link filtering and ripple suppression in inverters, converters, and motor drive subsystems that operate within the −25°C to 85°C temperature range.
• Energy Buffering — Energy hold-up and transient absorption in commercial UPS and backup power modules that need high capacitance and robust terminal connections.

Unique Advantages

• High Energy Density at 200 V: 4700 µF capacitance at 200 V provides substantial bulk storage for smoothing and hold-up without parallel banks of smaller capacitors.
• Secure, Serviceable Connections: Screw-terminal construction enables reliable, low-resistance electrical contact and easy replacement or maintenance in fielded equipment.
• Defined Endurance Behavior: 5000 hours at 85°C with specified post-test limits (±15% capacitance, tan δ ≤175% of initial spec, leakage ≤ initial) gives predictable aging for design life assessments.
• Broad Ripple Handling: Published ripple currents at 120 Hz and 100 kHz support both line-frequency and high-frequency switching environments.
• Standard Mechanical Footprint: φ51 × 100 mm package with standard 3‑leg bracket simplifies mechanical integration for panel- or chassis-mounted power modules.
• RoHS Compliance: Materials compliant with RoHS requirements for environmental regulations.
