LNY2V472MSEG

The LNY2V472MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering 4.7 mF (4700 µF) capacitance at a 350 V rating in a radial can with screw terminals. It is designed for general-purpose power applications where high voltage, substantial capacitance and secure terminal connections are required.

Key attributes include a wide operating temperature range (−40 °C to 85 °C), high ripple-current capability and a rated load life of 2000 hours at 85 °C, making it suitable for equipment downsizing and robust power-handling applications. The component is RoHS compliant and supplied in cardboard packing.

Key Features

• Capacitance & Tolerance — 4700 µF (4.7 mF) with tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Rated Voltage — 350 V DC rating suited to high-voltage power circuits.
• Screw-Terminal Mounting — Radial can with screw terminals for secure mechanical and electrical connections in panel- or chassis-mounted designs.
• Ripple-Current Performance — Low-frequency ripple current 15.8 A at 120 Hz and high-frequency ripple current 22.12 A at 10 kHz, supporting substantial AC ripple handling across common power frequencies.
• Endurance — Load life of 2000 hours at 85 °C when subjected to rated voltage plus rated ripple current.
• Leakage & Loss Angle — Specified leakage current of 3840 µA and tan δ (DF) of 0.25 under measurement conditions of 20 °C, 120 Hz.
• Temperature Range & Stability — Operating temperature from −40 °C to +85 °C with impedance stability characterized at low temperature (Z(−40 °C)/Z(+20 °C) ≤ 12 for the rated voltage range).
• Packaging & Compliance — Supplied in cardboard packing and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• High-voltage power supplies — Bulk energy storage and output smoothing in 350 V systems using 4700 µF capacitance and high ripple-current capability.
• Inverters and motor drives — DC-link and smoothing applications where sustained ripple currents (15.8 A @120 Hz; 22.12 A @10 kHz) and a 350 V rating are required.
• Industrial power electronics — General-purpose power filtering and decoupling in industrial equipment benefiting from screw-terminal mounting and 2000 h endurance at 85 °C.

Unique Advantages

• High-voltage, high-capacitance combination — 350 V rating with 4700 µF capacitance enables compact energy storage for higher-voltage designs.
• Robust ripple handling — Defined low- and high-frequency ripple-current specifications support reliable operation under significant AC ripple loads.
• Screw-terminal reliability — Screw-terminal radial can package provides secure, serviceable connections for chassis-mounted and field-serviceable installations.
• Thermal endurance — 2000-hour rated life at 85 °C under rated ripple conditions supports sustained operation in elevated-temperature environments.
• Measurable electrical stability — Specified tan δ and leakage current figures allow engineers to predict dissipation and insulation performance for system design and thermal planning.
• Regulatory and handling — RoHS compliance and cardboard packing simplify environmental compliance and logistics handling.
