LNK2W392MSEHBB

The LNK2W392MSEHBB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications. It provides 3.9 mF (3900 µF) capacitance at a rated voltage of 450 V in a radial can package with robust screw terminals.

Built for high‑duty power systems, the device delivers high ripple-current capability and a long load life (5,000 hours at 85°C), making it suitable where durable DC bus filtering and energy buffering are required across a –25°C to 85°C operating range.

Key Features

• Capacitance & Voltage: 3.9 mF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable for high‑voltage DC applications.
• High Ripple‑Current Handling: Rated ripple current of 14.20 A at 120 Hz (low frequency) and 19.88 A at 10 kHz (high frequency), supporting demanding power conversion loads.
• Long Endurance: Load life of 5,000 hours at 85°C under specified ripple conditions, with endurance validated by the manufacturer.
• Leakage Current: Typical leakage specified at 3970 μA after initial application of rated voltage, consistent with electrolytic capacitor behavior.
• Robust Mechanical Package: Radial can with screw terminals (φ76.2 × 110 mm size) for secure electrical and mechanical connections.
• Operating Environment: Rated for continuous operation from –25°C to +85°C and supplied in cardboard packing; RoHS compliant.

Typical Applications

• Power supply DC bus filtering: High capacitance and 450 V rating support bulk energy storage and smoothing on high‑voltage DC rails.
• Power conversion and inverters: Elevated ripple‑current capability at both low and high frequencies helps handle switching and ripple stresses in converters and inverters.
• Industrial power systems: Long life at 85°C and screw‑terminal mounting provide reliable performance in industrial and utility power electronics.

Unique Advantages

• High‑voltage energy storage: 450 V rating enables use on elevated DC buses without series stacking.
• Superior ripple tolerance: Specified 14.20 A (120 Hz) and 19.88 A (10 kHz) ripple currents reduce temperature rise and extend service life under ripple loading.
• Durable screw‑terminal connection: Screw terminals offer secure, low‑resistance terminations for heavy‑current applications and easy installation.
• Proven thermal endurance: 5,000‑hour rated life at 85°C supports designs that require sustained high‑temperature operation.
• Clear, verifiable specifications: Leakage current, tolerance, and frequency ripple coefficients are documented for engineering validation and thermal design.
