LNR1V474MSE

The LNR1V474MSE from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNR series, offering 470000 µF (470 mF) capacitance at a 35 V rating in a φ90 × 170 mm can. It is a polarized, radial can package designed for general-purpose power applications requiring large bulk capacitance and high ripple handling.

Engineered for sustained operation up to 85°C and RoHS compliant, this capacitor targets industrial and electronic equipment designs that need bulk energy storage, smoothing and DC-link support with screw-terminal mounting for secure electrical and mechanical connection.

Key Features

• Capacitance & Voltage — 470000 µF nominal capacitance at 35 V for high-capacity energy storage and smoothing in power circuits.
• Mounting & Package — Screw terminal, radial can with φ90 × 170 mm body for robust electrical connection and easy integration into chassis-mounted or bracket-mounted assemblies.
• Operating Temperature — Rated for –40°C to +85°C, supporting a wide ambient range appropriate for general-purpose equipment.
• Endurance — 5000 hours at 85°C under rated DC bias plus ripple current, with capacitance change specified within ±15% after endurance testing.
• High Ripple Current Capability — 32.6 A at 120 Hz (low frequency) and 37.49 A at 100 kHz (high frequency), enabling effective filtering of high-current ripple components.
• Tolerance & Polarization — Capacitance tolerance ±20% (–20% to +20%); polarized for conventional electrolytic use.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C), providing predictable standby characteristics.
• RoHS Compliant — Conforms to RoHS requirements for restricted substance content.

Typical Applications

• Bulk Energy Storage: Large capacitance supports energy buffering and hold-up in power systems and UPS/DC storage modules.
• DC-Link & Smoothing: High ripple current ratings and large capacitance enable smoothing of rectified DC and DC-link stabilization in converters and inverters.
• Power Conditioning in Industrial Equipment: Suitable for general-purpose industrial electronics where robust, chassis-mounted bulk capacitance is required.

Unique Advantages

• Very High Capacitance: 470000 µF provides substantial bulk storage per component, reducing the number of parallel units needed in high-capacitance designs.
• Screw-Terminal Reliability: Screw terminals deliver strong mechanical and electrical connections for high-current systems and ease of field installation or replacement.
• Designed for Continuous Operation: 5000-hour endurance at 85°C under rated bias and ripple current supports long-term reliability in demanding service conditions.
• Clear Leakage and Tolerance Specs: Defined leakage-current limits and ±20% tolerance enable predictable behavior for power budgeting and design verification.
• Wide Ambient Range: –40°C to +85°C operating range allows deployment across a broad set of general-purpose environments.
• RoHS Compliance: Facilitates use in products requiring restricted-substance conformance.
