LNY2G472MSEG

The LNY2G472MSEG is a screw-terminal aluminum electrolytic capacitor offering 4.7 mF (4700 µF) capacitance at a 400 V rating. Built in a radial can with screw terminals, it is intended for general-purpose high-voltage bulk capacitance applications where secure electrical and mechanical connections are required.

Key attributes include a ±20% capacitance tolerance, a tangent of loss angle (tan δ) of 0.25 (measured at 120 Hz, 20°C), rated endurance of 2000 hours at 85°C under applied ripple current, and a −40°C to +85°C operating range. The part is RoHS compliant and is offered in mass production with cardboard packing.

Key Features

• Capacitance and Tolerance — 4.7 mF (4700 µF) nominal capacitance with ±20% tolerance (120 Hz, 20°C).
• Rated Voltage — 400 V nominal rating suitable for high-voltage DC applications within the series' 350–450 V range.
• Screw-Terminal Construction — Radial can with screw terminals for robust electrical and mechanical connections; nominal bolt size for φ63.5 case is M5.
• Endurance at Elevated Temperature — Load-life specification of 2000 hours at 85°C with rated ripple current applied; components are restored to 20°C for post-test measurements.
• Ripple Current Capability — 16.1 A at 120 Hz and 22.54 A at 100 kHz, supporting higher AC current handling.
• Thermal and Low-Temperature Stability — Operating range −40°C to +85°C; impedance stability at low temperature specified with Z(−40°C)/Z(+20°C) ≤ 12.
• Leakage and Insulation Characteristics — Leakage current after 5 minutes not more than 3√CV (µA) or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Packaging & Compliance — Cardboard packing, mass production availability, and RoHS compliance.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing in high-voltage equipment where 400 V rating and large capacitance are required.
• Equipment downsizing — Suited for designs targeting reduced footprint while retaining high-capacitance, high-voltage performance.
• High-voltage DC filtering — Screw-terminal mounting and rated ripple current values support robust connections in DC filter and energy-buffer roles.

Unique Advantages

• High-voltage bulk capacitance: 4700 µF at 400 V provides substantial charge storage for high-voltage circuits.
• Secure screw-terminal assembly: Mechanical and electrical robustness for high-current connections and serviceability.
• Validated endurance at elevated temperature: 2000 hours at 85°C under rated ripple current ensures predictable performance over sustained operation.
• Broad operating temperature range: −40°C to +85°C with defined low-temperature impedance stability (Z(−40°C)/Z(+20°C) ≤ 12).
• Documented electrical integrity: Defined leakage current limits and insulation resistance specification for reliable system integration.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in mass production with cardboard packing.
