LNR2E472MSEB

The LNR2E472MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNR series, offering 4700 µF capacitance at a 250 V rating. Designed for general-purpose power applications, it provides high bulk capacitance and robust terminal connections for industrial and power-electronic systems.

Key value propositions include high ripple-handling capability, long endurance at elevated temperature, and a form factor sized for high-voltage power filtering and energy storage needs.

Key Features

• Capacitance and Voltage: 4700 µF (4.7 mF) nominal capacitance with a 250 V rated voltage, suitable for high-voltage DC filtering and energy storage.
• Tolerance and Loss: ±20% capacitance tolerance (120 Hz, 20°C) and tanδ (DF) 0.2 measured at 20°C, 120 Hz, providing predictable impedance and ESR behavior under standard measurement conditions.
• Ripple Current Performance: Low-frequency ripple current 7.3 A at 120 Hz and high-frequency ripple current 8.76 A at 100 kHz, enabling effective smoothing of both mains-frequency and switching-frequency ripple.
• Leakage Current: Leakage current specified at 3250 µA (per datasheet leakage measurement conditions), allowing designers to account for quiescent current in power budgets.
• Endurance and Temperature Range: Rated life 5000 hours at 85°C and an operating temperature range of −25°C to +85°C, supporting sustained operation in elevated-temperature environments.
• Mechanical and Mounting: Screw-terminal, radial can package with a φ63.5 mm body diameter and 100 mm length; standard three-leg mounting bracket supplied for φ51 and larger bodies, with nominal M5 terminal bolts for this diameter.
• Packaging and Compliance: Supplied in cardboard packing and RoHS compliant; product is in mass production.

Typical Applications

• General-purpose power supplies: Bulk energy storage and smoothing for high-voltage DC rails up to 250 V, leveraging 4700 µF capacitance and high ripple current ratings.
• Industrial power electronics: DC-link or filter capacitor in industrial converters and drives where robust screw-terminal connections and elevated-temperature endurance are required.
• Switch-mode power systems: Filtering and ripple suppression for switching supplies at both mains-frequency and switching-frequency components, supported by specified ripple current at 120 Hz and 100 kHz.

Unique Advantages

• High-voltage capability: 250 V rating lets designers use a single capacitor for higher-voltage DC circuits without stacking.
• Dual-band ripple handling: Specified ripple current at 120 Hz and 100 kHz addresses both low-frequency and high-frequency ripple sources in modern power systems.
• Extended endurance: 5000 hours at 85°C provides predictable lifetime performance for sustained elevated-temperature operation.
• Robust screw-terminal connection: Screw terminals and standard three-leg bracket (for φ63.5 body) deliver secure mechanical and electrical mounting for high-current applications.
• Clear specification set: Measured tanδ, leakage current, and tolerance information enable straightforward thermal and electrical design trade-offs.
• RoHS compliant and production-ready: RoHS status and mass-production availability simplify procurement and regulatory planning.
