LNK2V123MSEJ

The LNK2V123MSEJ is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for general‑purpose power applications. It provides high bulk capacitance (12,000 µF) at a 350 V rating with polarized screw‑terminal termination for robust electrical and mechanical connections.

Engineered for sustained operation at elevated temperature, this capacitor delivers a defined load life and ripple‑current capability for designs that require long service under DC bias and ripple stress.

Key Features

• High Capacitance & Voltage: 12,000 µF (12 mF) rated at 350 V for substantial energy storage in high‑voltage DC systems.
• Screw Terminal Package: Radial can with screw terminals for secure, low‑impedance connections and straightforward mounting.
• Load Life at Elevated Temperature: Specified load life of 5000 hours at 85 °C when subjected to DC bias plus rated ripple current; capacitance change remains within ±20% after endurance.
• High Ripple Current Capability: Rated ripple current 28.4 A at 120 Hz and 39.76 A at 10 kHz to handle significant AC ripple loads.
• Operating Temperature Range: −25 °C to +85 °C suitable for a range of commercial and industrial ambient conditions.
• Polarized Design: Polar capacitor construction for correct orientation in DC circuits.
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Electrical Reliability: Insulation resistance >100 MΩ at DC 500 V between terminal and bracket and voltage proof of AC 2500 V for 1 minute with no abnormalities.
• Physical Dimensions: Package dimensions L: 15 × D: 9 cm; maximum seated height 5.906 inches for mechanical planning.

Typical Applications

• General Purpose Power Systems — Intended for general‑purpose power applications that require high bulk capacitance at high voltage.
• High‑ripple DC Circuits — Suitable where sustained ripple current handling (28.4 A at 120 Hz; 39.76 A at 10 kHz) is required under rated conditions.
• Long‑life Power Designs — Designed for applications demanding defined endurance performance: 5000 hours at 85 °C under DC bias plus rated ripple current.

Unique Advantages

• Substantial energy storage: 12,000 µF at 350 V provides significant capacitance for bulk smoothing and DC link requirements.
• Robust termination: Screw‑terminal radial can simplifies secure connections and maintenance in fielded equipment.
• Documented endurance: 5000‑hour life at 85 °C under rated ripple current gives predictable ageing behavior for long‑term planning.
• High ripple tolerance across frequencies: Ripple ratings at both low (120 Hz) and high (10 kHz) frequencies support varied switching and line‑frequency environments.
• Design confidence: Leakage current and insulation resistance limits, plus voltage proof test criteria, provide measurable electrical reliability characteristics.
• Regulatory compliance: RoHS conformity supports use in locations requiring restricted‑substance compliance.
