LNK2W472MSEGBN

The LNK2W472MSEGBN is a screw-terminal aluminum electrolytic capacitor offering 4.7 mF (4700 µF) capacitance at a 450 V rating in a smaller-sized package. It is a polarized, radial can design intended for general-purpose electrical applications requiring high capacitance and elevated voltage handling.

Key engineering attributes include high ripple current capability, a rated operating temperature range of −25 °C to +85 °C, a 5000‑hour endurance at 85 °C under rated ripple, and RoHS compliance—making it suitable where sustained high-voltage bulk capacitance and reliable terminal connections are required.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 450 V for high-voltage bulk energy storage in a single component.
• Ripple Current Performance — Rated ripple current of 15.6 A at 120 Hz and 21.84 A at 10 kHz to support sustained AC ripple loading.
• Thermal & Lifetime Rating — Operating temperature range −25 °C to +85 °C with a specified endurance of 5000 hours at 85 °C under rated ripple current.
• Mounting & Package — Screw terminal mounting in a radial can with screw terminals for secure, serviceable connections.
• Electrical Characteristics — Polarized device with capacitance tolerance ±20% (at 120 Hz, 20 °C) and leakage current not more than 3√(C·V) µA or 5 mA after 5 minutes at rated voltage (at 20 °C), per datasheet.
• Size & Form — Smaller-sized series construction with physical dimension listing: L: 15.5 × D: 6.35 cm and a maximum seated height value provided in specifications.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power systems — Provides bulk capacitance and ripple handling where a 4.7 mF, 450 V polarized screw‑terminal capacitor is required; ripple current ratings and endurance support continuous operation.
• Industrial equipment and power supplies — Screw‑terminal package and high ripple capability suit industrial and commercial equipment requiring robust terminal connections and sustained energy buffering.
• High-voltage DC link or filtering — The 450 V rating and substantial capacitance make the part applicable in designs needing high-voltage bulk smoothing and DC link capacitance in general-purpose applications.

Unique Advantages

• High-voltage, high-capacitance combination: 4.7 mF at 450 V provides significant stored energy in a single capacitor for space-efficient design planning.
• Designed for sustained ripple: Specified ripple currents at both low and high frequencies (15.6 A at 120 Hz; 21.84 A at 10 kHz) reduce the need for parallel components to share ripple duty.
• Screw-terminal reliability: Radial can with screw terminals enables secure, serviceable connections for industrial assembly and maintenance.
• Durability at elevated temperature: 5000 hours load life at 85 °C under rated ripple current provides predictable long-term performance in thermal environments within the specified range.
• Measurable leakage limits: Leakage current specified as not more than 3√(C·V) µA or 5 mA after 5 minutes at rated voltage (20 °C) supports predictable standby and charge characteristics.
• RoHS compliance: Meets RoHS directive requirements for environmental regulatory conformity.
