LNY2W682MSEJ

The LNY2W682MSEJ is a screw-terminal aluminum electrolytic capacitor delivering 6.8 mF (6800 µF) at a 450 V rating with ±20% capacitance tolerance. Engineered for general-purpose power applications, it combines high capacitance and high-voltage capability in a radial can with screw terminals for secure, low-impedance connections.

Designed for durability, this part offers a 2000-hour load life at 85°C, measurable ripple-current capability, and a −40°C to +85°C operating range, making it suitable for equipment designs that require compact, high-capacitance energy storage and reliable long-term performance.

Key Features

• High Capacitance / High Voltage — 6.8 mF (6800 µF) rated at 450 V for applications needing substantial DC storage and voltage margin.
• Screw-Terminal Package — Radial can with screw terminals provides robust electrical and mechanical connections for power assemblies; nominal bolt size and terminal pitch information available in product documentation.
• Endurance — Rated for 2000 hours of applied ripple current at 85°C with post-test requirements for capacitance, tan δ and leakage current met after recovery to 20°C.
• Ripple Current Handling — Specified ripple current of 19.5 A at 120 Hz and 27.3 A at 10 kHz, supporting demanding AC ripple conditions in power systems.
• Temperature Performance — Operates from −40°C to +85°C; impedance stability at low temperature specified with Z(−40°C)/Z(+20°C) up to 12.
• Electrical Integrity — Leakage current limited to 3√(C·V) μA or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V voltage proof between terminal and bracket for 1 minute.
• Loss Tangent — Tangent of loss angle (tan δ) specified (product data: 0.25) for assessing equivalent series dissipation (measurement at 120 Hz, 20°C).
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• General-purpose power systems — For equipment designs that require high-capacitance, high-voltage bulk storage and smoothing using a screw-terminal, radial can package.
• Power conversion modules — Applicable where defined ripple-current capability (19.5 A @120 Hz, 27.3 A @10 kHz) and 450 V rating are needed for DC link or filter stages.
• Industrial equipment downsizing — Suited for designs targeting reduced footprint while maintaining high capacitance, as noted for equipment downsizing in product documentation.

Unique Advantages

• High-voltage, high-capacitance combination — Enables significant DC energy storage at 450 V in a single component, reducing the need for multiple parallel parts.
• Screw-terminal robustness — Provides secure mechanical and electrical termination for high-current or vibration-prone installations.
• Measured ripple-current ratings — Explicit ripple-current specifications at 120 Hz and 10 kHz help designers size thermal and lifetime performance accurately.
• Proven endurance specification — 2000-hour load life at 85°C with clear post-test acceptance criteria supports predictable long-term behavior in rated conditions.
• Wide operating temperature range — −40°C to +85°C operation and specified low-temperature impedance behavior (Z ratio) support varied environmental deployments.
• Compliance and electrical assurance — RoHS compliance, defined leakage current limits, insulation resistance and voltage-proof tests provide verifiable electrical integrity.
