LNY2W821MSEF

The LNY2W821MSEF is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose, high-voltage power applications. It delivers 820 µF capacitance at a 450 V rating with a screw-terminal package for secure, low-resistance connections.

Engineered for equipment downsizing and sustained ripple endurance, this part offers a rated lifetime of 2000 hours under rated ripple current at 85 °C and is RoHS compliant, making it suitable where high capacitance and reliable high-voltage performance are required.

Key Features

• Electrical Performance — 820 µF nominal capacitance at a 450 V rated voltage with ±20% tolerance (measured at 120 Hz, 20 °C).
• High ripple handling — Ripple current capability of 4.9 A at 120 Hz and 6.86 A at 10 kHz, supporting sustained AC ripple in high-voltage circuits.
• Reliability & endurance — Load-life specification of 2000 hours with DC plus rated ripple current at 85 °C; designed to meet defined endurance and shelf-life criteria after recovery to 20 °C.
• Leakage and insulation — Leakage current specified as not more than 3√(C·V) µA or 5 mA (after 5 minutes at 20 °C); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Voltage proof — No abnormality expected during AC 2500 V, 1 minute application between terminal and bracket as defined in the series datasheet.
• Mechanical & mounting — Screw terminal mounting on a radial can package for robust, serviceable connections and secure mounting.
• Operating environment — Rated for −40 °C to +85 °C operation and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical size — Compact radial can dimensions: length 6.0 cm × diameter 5.1 cm, polarized construction appropriate for DC power applications.

Typical Applications

• General-purpose power filtering — Bulk storage and smoothing in DC power supplies where a high-voltage 450 V capacitor is required.
• Equipment downsizing — Higher capacitance in a compact screw-terminal can supports reduced overall equipment footprint.
• High-voltage systems — Suitable for circuits that require a 450 V rated capacitor with defined ripple endurance.
• Screw-terminal power modules — Applications needing secure, low-impedance screw-terminal connections and easy serviceability.

Unique Advantages

• Higher capacitance for compact designs: 820 µF at 450 V helps reduce the number of components or board area needed for bulk energy storage.
• Screw-terminal reliability: Robust screw terminals provide secure electrical and mechanical connections for cabinet- or module-mounted power assemblies.
• Defined ripple endurance: Specified ripple currents at 120 Hz and 10 kHz plus a 2000-hour load-life at 85 °C offer predictable performance under continuous ripple stress.
• Broad operating range: −40 °C to +85 °C rating supports operation across common industrial and commercial environments.
• Compliance and testable safety margins: RoHS compliance, insulation resistance (>100 MΩ at DC 500 V), and AC voltage-withstand testing (AC 2500 V, 1 min) provide measurable safety and regulatory attributes.
