LNT2W123MSEJBB

The LNT2W123MSEJBB is a screw‑terminal aluminum electrolytic capacitor providing 12,000 µF capacitance at a 450 V rating. It is a polarized, radial can‑style part designed for general‑purpose high‑voltage power applications that require large bulk capacitance and robust ripple handling.

With a specified operating range to +105°C, a rated life of 5,000 hours at 105°C, and high low‑ and high‑frequency ripple current capability, this capacitor addresses demanding power filtering and energy‑storage needs where secure screw‑terminal connections are required.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a 450 V rated voltage suitable for high‑voltage bulk energy storage and smoothing in power systems.
• High Ripple Current Handling — Rated low‑frequency ripple current of 39.2 A (120 Hz) and high‑frequency ripple capability of 54.88 A (100 kHz), supporting continuous ripple stress in power circuits.
• Thermal Performance & Life — Operating temperature range from −25°C to +105°C with an endurance rating of 5,000 hours at 105°C under rated ripple and bias conditions.
• Electrical Losses — Specified tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics for thermal design.
• Leakage Current — Leakage current specified at 5,000 µA, suitable for high‑voltage power designs where initial leakage behavior must be known.
• Robust Mechanical Interface — Screw terminal mounting and radial can package (φ90 × 230 mm) provide secure, low‑resistance connections for high‑current power distribution.
• Compliance & Availability — RoHS‑compliant and in mass production; supplied in cardboard packing for handling and storage.

Typical Applications

• High‑voltage power filtering — Provides bulk capacitance and ripple smoothing where 450 V DC filtering is required.
• Bulk energy storage — Used in power systems that need large capacitance to stabilize DC rails and absorb transient energy within the specified voltage and temperature limits.
• Power conversion and DC link circuits — Supports DC link smoothing and ripple demands thanks to high ripple current ratings and screw‑terminal connections for reliable power wiring.

Unique Advantages

• Large single‑component capacitance: 12,000 µF reduces the number of parallel parts needed for bulk storage, simplifying BOM and layout.
• High voltage capability: 450 V rating enables use in higher‑voltage DC systems without series stacking of lower‑voltage capacitors.
• High ripple current tolerance: Strong low‑ and high‑frequency ripple specifications (39.2 A at 120 Hz, 54.88 A at 100 kHz) minimize heating under continuous AC ripple conditions.
• Designed for sustained thermal stress: 5,000‑hour endurance at 105°C provides predictable life for elevated‑temperature installations.
• Screw‑terminal reliability: Mechanical screw terminals ensure secure electrical and mechanical connection for high‑current power wiring.
• Regulatory compliance and production readiness: RoHS compliant and in mass production, facilitating integration into production designs.
