LNK2W153MSEJBB

The LNK2W153MSEJBB is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNK series, offering 15,000 µF capacitance at a 450 V rating. It is designed for general‑purpose power electronics where high bulk capacitance and robust high‑voltage performance are required.

As a radial, can‑style capacitor with screw terminals, this part targets applications that demand high ripple handling and long operational life in environments up to 85°C while meeting RoHS requirements.

Key Features

• Capacitance & Rated Voltage — 15,000 µF nominal capacitance rated for 450 V operation (±20% tolerance at 120 Hz, 20°C).
• Screw Terminal Mounting — Radial, can package with screw terminals for secure, high‑current connections and mechanical robustness.
• High Ripple Current Capability — 35.9 A at 120 Hz (low frequency) and 50.26 A at 10 kHz (high frequency), suitable for demanding smoothing and filtering duties.
• Electrical Losses & Leakage — tanδ of 0.2 at 20°C and 120 Hz; leakage current specified at 5000 µA.
• Reliability & Endurance — Load life of 5000 hours at 85°C with rated ripple current applied; endurance specifications specify capacitance within ±20% after test conditions.
• Operating Temperature — Rated for −25°C to +85°C operation, matching typical industrial ambient ranges.
• Form Factor & Packing — φ90×235L size (L: 23.5 cm × D: 9 cm) with cardboard packing; mass production status.
• RoHS Compliant — Conforms to RoHS directive requirements as noted in the series documentation.

Typical Applications

• Power supply bulk smoothing — Provides high capacitance and high‑voltage support for bulk energy storage and smoothing in AC/DC and DC/DC power supplies.
• Industrial power electronics — Suitable for inverter and drive systems that require sustained ripple handling and high voltage endurance.
• UPS and energy storage modules — Used for intermediate energy buffering and ripple mitigation where long endurance at elevated temperature is needed.

Unique Advantages

• Large energy storage at high voltage — 15,000 µF at 450 V gives substantial bulk capacitance for higher‑voltage systems without parallel arrays.
• Designed for high ripple environments — Specified ripple currents of 35.9 A (120 Hz) and 50.26 A (10 kHz) reduce the need for multiple parallel components in high‑current designs.
• Proven endurance under load — 5000 hours load life at 85°C with rated ripple current supports predictable lifetime planning.
• Robust mechanical termination — Screw terminals provide reliable, low‑impedance connections for heavy current paths and easy field wiring.
• Clear electrical behavior — ±20% capacitance tolerance and a specified tanδ help designers predict filtering and time‑constant performance.
• Production ready and compliant — Mass production status and RoHS compliance simplify procurement and regulatory alignment.
