LNK2W152MSEF

The LNK2W152MSEF from Nichicon is a smaller-sized, screw-terminal aluminum electrolytic capacitor rated for 1.5 mF (1500 µF) at 450 V. It is a polarized, radial can-type capacitor designed for general-purpose use where high voltage, elevated ripple handling and secure screw-terminal mounting are required.

Key value propositions include high ripple current capability, a long rated life under ripple stress (5000 hours at 85°C), and RoHS compliance, making this part suitable for robust power filtering and energy-storage roles in general purpose equipment.

Key Features

• Capacitance and Voltage: 1.5 mF (1500 µF) nominal capacitance with a 450 V rated voltage for high-voltage bulk storage and smoothing tasks.
• Screw Terminal Package: Radial can with screw terminals for secure, low-impedance connections and straightforward chassis or bracket mounting.
• Ripple Current Performance: Rated ripple current of 6.4 A at 120 Hz and 8.96 A at 10 kHz, enabling operation in applications with significant AC ripple content.
• Operating Range and Lifetime: Operational temperature range −25 °C to +85 °C with a rated load life of 5000 hours at 85 °C under applied rated ripple current.
• Tolerance and Polarization: Capacitance tolerance of −20% to +20%; polarized construction typical of aluminum electrolytic capacitors.
• Reliability Characteristics: Leakage-current limit after 5 minutes is not more than 3√CV (µA) or 5 mA (whichever is smaller). Insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket, and voltage proof of AC 2500 V for 1 minute between terminal and bracket (per datasheet).
• Compliance: RoHS compliant.
• Compact Footprint: Smaller-sized series with physical dimensions L: 9.5 cm × D: 5.1 cm for space-conscious designs.

Typical Applications

• General-purpose power systems: Use the 1.5 mF, 450 V rating for bulk smoothing and DC filtering in general-purpose power circuits where a high-voltage polarized capacitor is required.
• High-ripple environments: The 6.4 A (120 Hz) and 8.96 A (10 kHz) ripple ratings support use in circuits that experience substantial ripple currents.
• Chassis- or bracket-mounted power modules: Screw terminal construction enables secure electrical and mechanical installation in panel- or module-mounted power assemblies.

Unique Advantages

• High-voltage capability: 450 V rating allows deployment in higher-voltage DC circuits without the need for series stacking of lower-voltage parts.
• Designed for ripple stress: Explicit ripple current specifications at 120 Hz and 10 kHz provide predictable performance in AC-rich environments.
• Long rated life under load: 5000 hours at 85 °C with applied rated ripple current supports longer maintenance intervals and predictable replacement cycles.
• Secure screw-terminal connections: Radial can with screw terminals delivers reliable, low-resistance connections for high-current applications and robust mechanical mounting.
• Measured leakage and insulation criteria: Clear limits for leakage current and insulation resistance provide quantifiable electrical reliability metrics for design validation.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
