LNK2W182MSEG

The LNK2W182MSEG is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers 1.8 mF (1800 µF) capacitance at a 450 V rated voltage in a compact φ63.5 × 85 mm can with screw terminal mounting.

Engineered for sustained operation under ripple stress, this part targets equipment designs that require high-voltage bulk capacitance, long endurance, and robust terminal connections while remaining RoHS compliant.

Key Features

• Capacitance and Voltage: 1.8 mF (1800 µF) rated at 450 V for bulk energy storage and filtering in high-voltage circuits.
• Tolerance and Loss: Capacitance tolerance ±20% at 120 Hz, 20°C and tangent of loss angle (tan δ / DF) specified at 0.2.
• Endurance and Temperature: Rated for 5000 hours of load life at 85°C; operating temperature range is −25°C to +85°C.
• Ripple Current Capability: Ripple current ratings of 7.6 A at 120 Hz and 10.64 A at 10 kHz (frequency-dependent performance).
• Robust Electrical Safety Characteristics: Leakage current after 5 minutes is limited to 3√(C·V) µA or 5 mA, whichever is smaller; insulation resistance >100 MΩ at DC 500 V; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Mechanical and Mounting: Screw terminal radial can package with M5-compatible terminal dimensions (φ63.5 size); nominal dimensions L: 85 mm × D: 63.5 mm.
• Marking and Compliance: Printed white-on-black sleeve marking; RoHS compliant and supplied in cardboard packing for mass production use.

Typical Applications

• General-purpose power supplies: Provides high-voltage bulk capacitance and ripple handling for filtering and energy buffering in general-purpose power electronics.
• Industrial equipment: Suited for equipment requiring durable screw-terminal connections and long endurance at elevated temperatures.
• High-voltage DC bus and smoothing: Used where 450 V rated capacitance and defined ripple current capability are required for DC link stabilization and smoothing.

Unique Advantages

• High-voltage bulk energy storage: 1.8 mF at 450 V provides substantial capacitance for high-voltage applications without resorting to multiple lower-voltage parts.
• Long rated life under ripple: 5000-hour endurance at 85°C with applied rated ripple current supports longevity in demanding thermal and electrical environments.
• Clear electrical limits and safety data: Specified leakage current limits, insulation resistance, and AC voltage proof provide verifiable electrical characteristics for design validation.
• Screw-terminal mounting: Provides a robust, serviceable electrical connection well suited to panel or chassis installations where secure bolted terminals are required.
• Frequency-aware ripple performance: Published ripple current values at 120 Hz and 10 kHz help designers evaluate performance across typical power-frequency and higher-frequency ripple conditions.
• RoHS compliant and production-ready: Conforms to RoHS and supplied in cardboard packing for mass production deployment.
