LNY2W682MSEGBN

The LNY2W682MSEGBN is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNY series, rated at 6800 µF and 450 V. Engineered for general-purpose power applications, this radial can with screw terminals is designed to support equipment downsizing while delivering high capacitance and robust high-voltage performance.

Key value propositions include a high nominal capacitance at 450 V, a compact cylindrical package (φ63.5 × 210L), a 2000-hour load life under rated ripple at 85°C, and RoHS compliance for environmental compatibility.

Key Features

• High Capacitance and Voltage — 6800 µF nominal capacitance at a 450 V rating provides substantial energy storage for high-voltage power applications.
• Robust Screw-Terminal Package — Radial can with screw terminals offers secure, low-impedance connections suitable for high-current and serviceable installations.
• Load Life and Temperature Range — Rated for 2000 hours with applied ripple current at 85°C and an operating temperature range of −40°C to +85°C to support demanding thermal environments.
• Ripple Current Capability — Supports 19.1 A at 120 Hz and 26.74 A at 10 kHz, enabling reliable handling of applied ripple across a broad frequency range.
• Electrical Reliability — Leakage current after 5 minutes is limited to 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance exceeds 100 MΩ at DC 500 V; and voltage proof is specified at AC 2500 V for 1 minute between terminal and bracket.
• Capacitance Stability and Tolerance — Capacitance tolerance is ±20% (measured at 120 Hz, 20°C); low-temperature impedance stability is specified with Z(−40°C)/Z(+20°C) ≤ 12.
• Compact Form Factor — Cylindrical dimensions φ63.5 × 210L (L: 21 × D: 6.35 cm) support space-constrained designs and equipment downsizing.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power supplies — Energy storage and bulk smoothing in high-voltage power supply rails where 450 V ratings and large capacitance are required.
• Compact power systems — Enables equipment downsizing by delivering high capacitance in a screw-terminal radial can package for space-constrained enclosures.
• High-voltage filtering — Filtering and ripple suppression in high-voltage circuits using the capacitor's rated ripple current capabilities at both low and high frequencies.

Unique Advantages

• High-energy storage at 450 V: Enables designers to meet high-voltage bulk capacitance requirements without parallel arrays of smaller parts.
• Serviceable screw terminals: Provides secure mechanical and electrical connections that simplify installation and maintenance in industrial assemblies.
• Designed for sustained ripple conditions: Rated ripple currents of 19.1 A (120 Hz) and 26.74 A (10 kHz) support continuous AC ripple loading in power conversion stages.
• Specified endurance under load: 2000-hour load life at 85°C with applied ripple current gives a measurable reliability baseline for thermal and electrical stress planning.
• Verified electrical safeguards: Leakage current limits, high insulation resistance, and AC 2500 V voltage proof provide quantifiable electrical performance characteristics for system validation.
• RoHS compliance: Meets environmental regulatory requirements for restricted substances.
