LNR1A474MSE

The LNR1A474MSE is a screw-terminal aluminum electrolytic capacitor engineered for general-purpose power electronics that require very large capacitance in a robust, serviceable package. With 470000 µF (470 mF) rated at 10 V, this radial can with screw terminals delivers bulk energy storage and smoothing capability in industrial and power system applications.

Designed for long-term operation, the LNR1A474MSE is specified for a 5000-hour endurance at 85°C and supports high ripple currents across both low- and high-frequency regimes, offering a durable solution where sustained performance under bias and ripple is required.

Key Features

• High Capacitance: 470000 µF (470 mF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C—provides substantial bulk energy storage for smoothing and buffering.
• Rated Voltage: 10 V rated working voltage matching low-voltage power rails and energy storage applications.
• Screw Terminal Mounting: Radial can with screw terminals for secure electrical connection and straightforward serviceability in field or bench assemblies.
• High Ripple Current Capability: Low-frequency ripple current 19 A (120 Hz) and high-frequency ripple current 21.85 A (100 kHz) to handle sustained AC ripple across common power-conversion frequencies.
• Loss and Leakage Characteristics: Specified tanδ (DF) of 1.2 (measured at 20°C, 120 Hz) and leakage current listed at 5000 µA, enabling predictable dissipation and self-discharge behavior.
• Endurance and Stability: Life-tested 5000 hours at 85°C under rated DC bias plus rated ripple current; capacitance change within ±15% and leakage current remains at or below initial specified value after endurance testing.
• Operating Temperature Range: –40°C to +85°C (for 10 V rated voltage) for use across typical industrial ambient conditions.
• Mechanical & Packaging: Body dimension φ63.5 × 120 mm length, furnished with a 3-leg mounting bracket as standard for this diameter; supplied in cardboard packing and available in mass production.
• Compliance: RoHS compliant.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing where high capacitance and screw-terminal connections are required.
• Power supply filtering — Use in low-voltage power rails to reduce ripple and stabilize DC outputs thanks to the high capacitance and specified ripple-current ratings.
• Energy buffering for power electronics — Provides transient energy during load changes and supports sustained ripple currents in converters and inverters.

Unique Advantages

• Massive capacitance in a single component: 470000 µF minimizes the number of parts needed for large bulk-storage requirements.
• Screw-terminal reliability: Robust screw terminals and a 3-leg bracket (standard for φ63.5 diameter) provide secure mounting and easy field replacement or maintenance.
• High ripple endurance across frequencies: Rated ripple currents at both 120 Hz and 100 kHz ensure consistent performance in low- and high-frequency circuits.
• Long-term thermal endurance: 5000-hour rating at 85°C supports designs that must maintain capacitance and leakage characteristics under continuous elevated temperature and bias.
• Clear electrical characterization: Specified tanδ, leakage current, and tolerance figures enable predictable system-level thermal and discharge behavior.
• Regulatory readiness: RoHS compliance simplifies integration into assemblies targeting restricted-substance requirements.
