LNY2W472MSEHBN

The LNY2W472MSEHBN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose high-voltage applications. It combines 4.7 mF (4700 µF) capacitance with a 450 V rated voltage in a radial can with secure screw terminals for robust electrical connections.

Engineered for elevated-temperature operation and equipment downsizing, this part offers a 2000-hour load life at 85°C, RoHS compliance, and performance data useful for power electronics designers and procurement teams working on high-voltage bulk-filtering and energy-storage needs.

Key Features

• Electrical Capacity: 4.7 mF (4700 µF) rated capacitance with ±20% tolerance (120 Hz, 20°C), delivering substantial bulk energy storage at high voltage.
• High Voltage Rating: 450 V rated voltage suitable for high-voltage DC applications within the LNY series range.
• Low-Frequency Ripple Current: 15.6 A at 120 Hz, supporting sustained ripple handling for DC link and smoothing duties.
• High-Frequency Ripple Current: 21.84 A at 10 kHz, enabling improved performance under higher-frequency ripple conditions.
• Loss Tangent (tan δ): tanδ 0.25 (measurement reference provided in datasheet), useful for estimating dissipation and thermal considerations.
• Lifetime and Endurance: Rated for 2000 hours at 85°C with rated ripple current applied, supporting reliable operation under elevated-temperature loading.
• Temperature Range and Low-Temperature Stability: Operating range –40°C to +85°C; impedance ratio Z(–40°C)/Z(+20°C) up to 12 for the 350–450 V range as specified in the series datasheet.
• Mounting and Mechanical: Screw terminal radial can package (φ76.2 × 105 mm length), nominal M5 bolt terminal interface for secure connections and mechanical stability.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage is not more than 3√CV (µA) or 5 mA, whichever is smaller, per datasheet conditions.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Identification: Marking printed in white on a black sleeve for clear part identification.

Typical Applications

• General-purpose power equipment — bulk energy storage and smoothing in high-voltage DC circuits where robust capacitance and secure screw connections are required.
• Power supplies and converters — DC link and filtering roles that demand substantial capacitance at up to 450 V and dependable ripple-current performance.
• Industrial electronics — applications that benefit from high-voltage capacitance with a rugged screw-terminal mounting and 2000-hour endurance at 85°C.

Unique Advantages

• High-voltage bulk capacitance: 4700 µF at 450 V provides significant energy-storage capability for high-voltage systems, reducing the number of parallel components required.
• Screw-terminal reliability: M5-compatible screw terminals deliver secure electrical and mechanical connections for heavy-current and industrial installations.
• Designed for elevated-temperature duty: 2000-hour rated life at 85°C under rated ripple current supports stable long-term operation in warm environments.
• Broad ripple-current capability: Specified ripple currents at 120 Hz and 10 kHz help designers assess thermal and lifetime trade-offs across operating conditions.
• Compact high-capacitance form factor: φ76.2 × 105 mm radial can helps with equipment downsizing while maintaining high capacitance and voltage rating.
• Regulatory peace of mind: RoHS compliance supports environmental and regulatory requirements for modern electronic systems.
