LNR1K473MSEB

The LNR1K473MSEB is a screw-terminal, radial aluminum electrolytic capacitor in Nichicon's LNR series. It delivers 47 mF capacitance at an 80 V rating in a robust φ63.5 mm × 100 mm can designed for general-purpose power applications.

Engineered for bulk energy storage and high ripple environments, this polarized capacitor combines high capacitance, elevated ripple-current capability, and a 5 000‑hour endurance at 85 °C to support demanding industrial and power-electronics designs.

Key Features

• Capacitance & Voltage — 47 000 µF (47 mF) rated at 80 V, ±20% tolerance for stable bulk energy storage and smoothing.
• High Ripple Current — 12.7 A at 120 Hz (low frequency) and 14.61 A at 100 kHz (high frequency), supporting heavy ripple loads and long-term filtering performance.
• Leakage and Loss — Specified leakage current of 5 000 µA and a tangent of loss angle (tan δ) of 0.25 for predictable DC bias and dissipation behavior.
• Endurance & Temperature — Rated for 5 000 hours at 85 °C with an operating range of −40 °C to +85 °C.
• Package & Mounting — Radial, can-style package with screw terminals for secure bolted connections; body diameter φ63.5 mm and length 100 mm. Capacitors φ51 mm or larger are furnished with a 3‑leg mounting bracket as standard.
• Polarized, General-Purpose — Polar construction intended for general-purpose power applications; RoHS compliant.

Typical Applications

• Power filtering and bulk energy storage — Large capacitance and high ripple-current ratings make this capacitor suitable for smoothing DC bus voltages and storing energy in power subsystems.
• Industrial power supplies — Designed to handle sustained ripple and elevated temperatures common in industrial converters and supplies.
• UPS and backup power systems — High capacitance and endurance support short-term energy buffering and ride-through functions.
• Inverters and motor drives — Screw-terminal construction and robust ripple capability simplify integration into high-current power assemblies.

Unique Advantages

• Large-capacity solution: 47 000 µF at 80 V reduces the number of capacitors required for bulk storage compared to lower-capacitance parts, simplifying BOM and PCB layout.
• High ripple handling: Dual ripple specifications (12.7 A at 120 Hz and 14.61 A at 100 kHz) provide measurable performance across both low- and high-frequency regimes.
• Secure, serviceable connections: Screw-terminal interface enables reliable bolted terminations and straightforward field installation or replacement.
• Designed for elevated duty: 5 000‑hour life at 85 °C and an operating range of −40 °C to +85 °C support long-term operation in thermally demanding environments.
• Mounting flexibility: φ63.5 mm housing with standard 3‑leg bracket for larger-diameter cans facilitates stable mechanical installation in power racks and enclosures.
• Regulatory alignment: RoHS compliance supports environmental and materials requirements in modern designs.
