LNY2G682MSEG

The LNY2G682MSEG is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-capacitance, high-voltage general-purpose applications. It delivers 6.8 mF of capacitance at a 400 V rating with a screw terminal mounting for secure connections in power assemblies.

Engineered for reliability in demanding thermal and ripple environments, this RoHS‑compliant part offers a 2000 hour load life at 85°C under rated ripple current and is suited for equipment downsizing where high capacitance and secure mounting are required.

Key Features

• Capacitance and Voltage – 6.8 mF (6800 µF) rated at 400 V, providing significant bulk energy storage for high-voltage power rails.
• Screw Terminal Mounting – Radial can with screw terminals for robust, low-resistance connections and straightforward mechanical fastening.
• High Ripple Handling – Rated ripple current: 19.1 A at 120 Hz and 26.74 A at 10 kHz, enabling effective smoothing under both low- and high-frequency ripple conditions.
• Thermal and Lifetime Performance – Operating temperature range of −40°C to +85°C with a rated load life of 2000 hours at 85°C when subjected to rated ripple current.
• Stability at Low Temperature – Impedance ratio Z(−40°C)/Z(+20°C) specified as 12, supporting predictable behavior in cold-start conditions.
• Leakage and Insulation Characteristics – Leakage current after 5 minutes is ≤ 3√CV (µA) or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V voltage proof for 1 minute between terminal and bracket.
• Package and Tolerance – Radial can with screw terminals, capacitance tolerance ±20% (120 Hz, 20°C); physical size approximately L 16.5 cm × D 6.35 cm.
• RoHS Compliant – Meets RoHS directive requirements for restricted substances.

Typical Applications

• Power Filtering and Smoothing – Bulk capacitance and high-voltage rating make this capacitor suitable for smoothing DC bus and supply rails in general-purpose power electronics.
• DC Link and Energy Storage – High capacitance at 400 V supports energy buffering and DC-link stability in equipment requiring substantial stored energy.
• Industrial Power Equipment – Screw-terminal mounting and robust insulation characteristics provide secure electrical and mechanical integration in rack or chassis-mounted power systems.

Unique Advantages

• High Capacitance at High Voltage – 6.8 mF at 400 V supplies significant stored energy in a single component, reducing the need for parallel arrays.
• Secure, Serviceable Connections – Screw terminals enable reliable, maintainable wiring and strong mechanical retention for heavy-current applications.
• Designed for Thermal and Ripple Stress – Rated ripple currents at both 120 Hz and 10 kHz plus a 2000 hour life at 85°C under rated ripple current support sustained performance in demanding environments.
• Predictable Low-Temperature Behavior – Specified impedance ratio at −40°C helps designers account for cold-start and extended operating-range behavior.
• Safety and Insulation Assurance – Insulation resistance and AC voltage proof ratings between terminal and bracket provide measurable electrical isolation characteristics for system design.
• Regulatory Compliance – RoHS compliance supports use in applications requiring restricted-substance conformity.
