LNR2E472MSEN

The LNR2E472MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNR series, offering 4.7 mF (4700 µF) capacitance at a 250 V rating. It is a radial, can-style capacitor with screw terminals designed for general-purpose power applications that require bulk energy storage and high ripple-handling capability.

Key design attributes include high ripple current capability (7.3 A at 120 Hz, 8.76 A at 100 kHz), an endurance rating of 5000 hours at 85°C, a wide operating temperature range of −25°C to +85°C (for 160–250 V ratings), RoHS compliance, and cardboard packing for shipment. The part is in mass production.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a tolerance of −20% to +20% at a rated voltage of 250 V.
• Screw-Terminal Power Package — Radial can with screw terminals; body diameter φ63.5 mm and length 100 mm. Terminal hardware for φ63.5 is supplied with M5 nominal bolt sizing and standard 3‑leg mounting bracket.
• High Ripple Current — Low-frequency ripple current 7.3 A at 120 Hz and high-frequency ripple current 8.76 A at 100 kHz, enabling robust AC ripple handling on DC rails.
• Electrical Loss and Leakage — tan δ (loss tangent) of 0.2 (measured at 20°C, 120 Hz) and a specified leakage current of 3250 µA.
• Endurance & Temperature — Rated for 5000 hours at 85°C with operating temperature range −25°C to +85°C (for 160–250 V rating), and recovery-tested to meet capacitance, tan δ and leakage specifications after endurance stress.
• Packaging & Compliance — Supplied in cardboard packing for handling and storage; RoHS compliant and available in mass-production quantities.

Typical Applications

• Power supply filtering — Bulk energy storage and smoothing for 250 V DC rails, leveraging the 4700 µF capacitance and high ripple current specifications.
• DC link decoupling — Energy buffering and ripple reduction in converter and inverter DC links where sustained ripple handling and 250 V rating are required.
• Industrial electronics — General-purpose power conditioning in equipment operating within −25°C to +85°C and requiring long endurance (5000 h at 85°C).

Unique Advantages

• High energy density at 250 V: 4.7 mF nominal capacitance provides substantial bulk storage on higher-voltage rails without increasing component count.
• Robust ripple capability: Dual ripple ratings (7.3 A at 120 Hz and 8.76 A at 100 kHz) cover both low- and high-frequency AC components common in power systems.
• Long-term reliability: Endurance tested to 5000 hours at 85°C ensures stability of capacitance and controlled tan δ and leakage after stress.
• Service-friendly screw terminals: Screw-terminal construction with M5 nominal bolts and standard mounting brackets simplifies installation and replacement in field or bench environments.
• Regulatory readiness: RoHS compliance supports deployment in designs requiring restricted-substance compliance.
