LNK2W122MSEFBN

The LNK2W122MSEFBN is a screw-terminal aluminum electrolytic capacitor providing 1.2 mF (1200 µF) capacitance at a 450 V rating. Built as a radial can with screw terminals, it targets general-purpose power applications that require high-voltage bulk capacitance with secure, high-current connections.

This capacitor combines high ripple-current capability, long endurance at elevated temperature, and RoHS compliance to support production designs requiring reliable energy storage and filtering in industrial and general-purpose power systems.

Key Features

• Capacitance & Rated Voltage — 1.2 mF (1200 µF) nominal capacitance rated for 450 V with ±20% tolerance (120 Hz, 20°C).
• Screw-Terminal Package — Radial can with screw terminals for robust, low-resistance mechanical and electrical connections in panel- or chassis-mounted systems.
• High Ripple-Current Capability — 6.3 A at 120 Hz (low frequency) and 8.82 A at 10 kHz (high frequency) to handle waveform and switching currents.
• Endurance at Elevated Temperature — Rated load life of 5000 hours at 85°C with specified endurance recovery criteria after test.
• Leakage and Loss Characteristics — Specified leakage current of 2200 µA and tangent of loss angle (tan δ) of 0.2 for predictable performance.
• Operating Range — Specified operating temperature range from -25°C to +85°C.
• Form Factor & Packing — Size φ51 × 85L (L: 8.5 × D: 5.1 cm) in a radial can; shipped in cardboard packing for mass-production handling.
• Regulatory Status — RoHS compliant.

Typical Applications

• General-purpose power systems — Bulk energy storage and DC-link filtering where a 1.2 mF, 450 V screw-terminal capacitor is required for reliable smoothing and decoupling.
• Industrial power supplies — High-voltage supply rails and power modules that benefit from screw-terminal mounting for secure mechanical and electrical connections.
• High-ripple environments — Circuits subjected to significant low- or high-frequency ripple currents, leveraging the 6.3 A (120 Hz) and 8.82 A (10 kHz) ripple-current ratings.

Unique Advantages

• High-voltage bulk capacitance: 450 V rating with 1.2 mF capacitance supports high-voltage DC-link and energy-storage demands.
• Robust connection method: Screw-terminal construction provides secure, low-resistance terminations suitable for heavy-current and vibration-prone installations.
• Designed for elevated-temperature endurance: 5000-hour rated life at 85°C offers predictable long-term behavior under sustained thermal and ripple stress.
• Clear electrical limits: Specified leakage current (2200 µA) and tan δ (0.2) enable accurate thermal and loss budgeting in power designs.
• High ripple-current handling: Separate low- and high-frequency ripple ratings allow designers to size capacitors for both mains-frequency and switching-frequency stress.
• Production-ready packaging: Cardboard packing and mass-production status simplify procurement and assembly planning.
